+# ☁️ Cloud Deployment
+
+Deploy 9Router on VPS or Docker for remote access and production use.
+
+---
+
+## 🖥️ VPS Deployment
+
+### Prerequisites
+
+- Ubuntu 20.04+ or similar Linux distribution
+- Node.js 20+
+- Git
+- Root or sudo access
+
+### Step 1: Clone Repository
+
+```bash
+git clone https://github.com/decolua/9router.git
+cd 9router/app
+```
+
+### Step 2: Install Dependencies
+
+```bash
+npm install
+```
+
+### Step 3: Build Application
+
+```bash
+npm run build
+```
+
+### Step 4: Configure Environment Variables
+
+Create a `.env` file or export variables:
+
+```bash
+export JWT_SECRET="your-secure-secret-change-this-to-random-string"
+export INITIAL_PASSWORD="your-secure-password"
+export DATA_DIR="/var/lib/9router"
+export NODE_ENV="production"
+```
+
+**Environment Variables:**
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `JWT_SECRET` | Auto-generated | **MUST change in production!** Used for JWT token signing |
+| `INITIAL_PASSWORD` | `123456` | Dashboard login password |
+| `DATA_DIR` | `~/.9router` | Database and data storage path |
+| `NODE_ENV` | `development` | Set to `production` for deployment |
+| `ENABLE_REQUEST_LOGS` | `false` | Enable debug request/response logs |
+
+### Step 5: Create Data Directory
+
+```bash
+sudo mkdir -p /var/lib/9router
+sudo chown $USER:$USER /var/lib/9router
+```
+
+### Step 6: Start Application
+
+```bash
+npm run start
+```
+
+### Step 7: Setup PM2 for Production
+
+PM2 keeps your application running and restarts it on crashes:
+
+```bash
+# Install PM2 globally
+npm install -g pm2
+
+# Start 9Router with PM2
+pm2 start npm --name 9router -- start
+
+# Save PM2 configuration
+pm2 save
+
+# Setup PM2 to start on system boot
+pm2 startup
+# Follow the instructions printed by the command above
+```
+
+**PM2 Management Commands:**
+
+```bash
+# View logs
+pm2 logs 9router
+
+# Restart application
+pm2 restart 9router
+
+# Stop application
+pm2 stop 9router
+
+# View status
+pm2 status
+
+# Monitor resources
+pm2 monit
+```
+
+---
+
+## 🐳 Docker Deployment
+
+### Option 1: Using Dockerfile
+
+Create a `Dockerfile` in the `app` directory:
+
+```dockerfile
+FROM node:20-alpine
+
+WORKDIR /app
+
+# Copy package files
+COPY package*.json ./
+
+# Install dependencies
+RUN npm ci --only=production
+
+# Copy application files
+COPY . .
+
+# Build application
+RUN npm run build
+
+# Expose ports
+EXPOSE 3000 20128
+
+# Set environment variables
+ENV NODE_ENV=production
+ENV DATA_DIR=/app/data
+
+# Create data directory
+RUN mkdir -p /app/data
+
+# Start application
+CMD ["npm", "run", "start"]
+```
+
+**Build and Run:**
+
+```bash
+# Build image
+docker build -t 9router .
+
+# Run container
+docker run -d \
+  --name 9router \
+  -p 3000:3000 \
+  -p 20128:20128 \
+  -e JWT_SECRET="your-secure-secret-change-this" \
+  -e INITIAL_PASSWORD="your-secure-password" \
+  -v 9router-data:/app/data \
+  9router
+```
+
+### Option 2: Docker Compose
+
+Create `docker-compose.yml`:
+
+```yaml
+version: '3.8'
+
+services:
+  9router:
+    build: .
+    container_name: 9router
+    ports:
+      - "3000:3000"
+      - "20128:20128"
+    environment:
+      - NODE_ENV=production
+      - JWT_SECRET=your-secure-secret-change-this
+      - INITIAL_PASSWORD=your-secure-password
+      - DATA_DIR=/app/data
+    volumes:
+      - 9router-data:/app/data
+    restart: unless-stopped
+
+volumes:
+  9router-data:
+```
+
+**Run with Docker Compose:**
+
+```bash
+# Start services
+docker-compose up -d
+
+# View logs
+docker-compose logs -f
+
+# Stop services
+docker-compose down
+
+# Rebuild and restart
+docker-compose up -d --build
+```
+

+
+## 🌐 Reverse Proxy with Nginx
+
+### Why Use Nginx?
+
+- SSL/TLS termination
+- Domain name mapping
+- Load balancing
+- Better security
+
+### Step 1: Install Nginx
+
+```bash
+sudo apt update
+sudo apt install nginx
+```
+
+### Step 2: Configure Nginx
+
+Create `/etc/nginx/sites-available/9router`:
+
+```nginx
+server {
+    listen 80;
+    server_name your-domain.com;
+
+    # Redirect HTTP to HTTPS
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name your-domain.com;
+
+    # SSL certificates (use certbot to generate)
+    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
+
+    # SSL configuration
+    ssl_protocols TLSv1.2 TLSv1.3;
+    ssl_ciphers HIGH:!aNULL:!MD5;
+    ssl_prefer_server_ciphers on;
+
+    # Proxy to 9Router
+    location / {
+        proxy_pass http://localhost:3000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_cache_bypass $http_upgrade;
+        
+        # SSE support - CRITICAL for streaming
+        proxy_buffering off;
+        proxy_read_timeout 86400;
+    }
+
+    # API endpoint
+    location /v1 {
+        proxy_pass http://localhost:20128;
+        proxy_http_version 1.1;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        
+        # SSE support - CRITICAL for streaming
+        proxy_buffering off;
+        proxy_read_timeout 86400;
+    }
+}
+```
+
+### Step 3: Enable Site
+
+```bash
+# Create symbolic link
+sudo ln -s /etc/nginx/sites-available/9router /etc/nginx/sites-enabled/
+
+# Test configuration
+sudo nginx -t
+
+# Reload Nginx
+sudo systemctl reload nginx
+```
+
+### Step 4: Setup SSL with Let's Encrypt
+
+```bash
+# Install certbot
+sudo apt install certbot python3-certbot-nginx
+
+# Obtain SSL certificate
+sudo certbot --nginx -d your-domain.com
+
+# Auto-renewal is configured automatically
+# Test renewal
+sudo certbot renew --dry-run
+```
+
+---
+
+## 🔒 Security Considerations
+
+### 1. Change Default Credentials
+
+**CRITICAL:** Change `JWT_SECRET` and `INITIAL_PASSWORD` before deployment:
+
+```bash
+# Generate secure JWT secret
+openssl rand -base64 32
+
+# Use this value for JWT_SECRET
+export JWT_SECRET="generated-secret-here"
+```
+
+### 2. Firewall Configuration
+
+```bash
+# Allow SSH
+sudo ufw allow 22/tcp
+
+# Allow HTTP/HTTPS (if using Nginx)
+sudo ufw allow 80/tcp
+sudo ufw allow 443/tcp
+
+# If NOT using reverse proxy, allow 9Router ports
+sudo ufw allow 3000/tcp
+sudo ufw allow 20128/tcp
+
+# Enable firewall
+sudo ufw enable
+```
+
+### 3. Restrict Dashboard Access
+
+If you only need API access, restrict dashboard port:
+
+```bash
+# Only allow localhost access to dashboard
+sudo ufw deny 3000/tcp
+```
+
+Access dashboard via SSH tunnel:
+
+```bash
+ssh -L 3000:localhost:3000 user@your-server.com
+# Then open http://localhost:3000 in your browser
+```
+
+### 4. Regular Updates
+
+```bash
+# Update system packages
+sudo apt update && sudo apt upgrade -y
+
+# Update 9Router
+cd /path/to/9router/app
+git pull
+npm install
+npm run build
+pm2 restart 9router
+```
+
+### 5. Backup Strategy
+
+```bash
+# Backup data directory
+tar -czf 9router-backup-$(date +%Y%m%d).tar.gz /var/lib/9router
+
+# Automated daily backup (add to crontab)
+0 2 * * * tar -czf /backups/9router-$(date +\%Y\%m\%d).tar.gz /var/lib/9router
+```
+
+---
+
+## 📊 Monitoring
+
+### Check Application Status
+
+```bash
+# PM2 status
+pm2 status
+
+# View logs
+pm2 logs 9router --lines 100
+
+# Monitor resources
+pm2 monit
+```
+
+### Nginx Logs
+
+```bash
+# Access logs
+sudo tail -f /var/log/nginx/access.log
+
+# Error logs
+sudo tail -f /var/log/nginx/error.log
+```
+
+### System Resources
+
+```bash
+# CPU and memory usage
+htop
+
+# Disk usage
+df -h
+
+# Network connections
+netstat -tulpn | grep -E '3000|20128'
+```
+
+---
+
+## 🚨 Troubleshooting
+
+### Application Won't Start
+
+```bash
+# Check logs
+pm2 logs 9router
+
+# Check if ports are in use
+sudo lsof -i :3000
+sudo lsof -i :20128
+
+# Check environment variables
+pm2 env 9router
+```
+
+### Nginx 502 Bad Gateway
+
+```bash
+# Check if 9Router is running
+pm2 status
+
+# Check Nginx error logs
+sudo tail -f /var/log/nginx/error.log
+
+# Test Nginx configuration
+sudo nginx -t
+```
+
+### SSE Streaming Not Working
+
+Ensure `proxy_buffering off` is set in Nginx configuration for SSE support.
+
+### Permission Denied Errors
+
+```bash
+# Fix data directory permissions
+sudo chown -R $USER:$USER /var/lib/9router
+chmod 755 /var/lib/9router
+```

+
+---
+
+## 🔍 Troubleshooting
+
+### Port Already in Use
+
+If port 20128 or 3000 is already in use:
+
+```bash
+# Find process using the port (macOS/Linux)
+lsof -i :20128
+lsof -i :3000

+# Or fix npm permissions (recommended)
+mkdir ~/.npm-global
+npm config set prefix '~/.npm-global'
+echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
+source ~/.bashrc
+```
+
+### Data Directory Issues
+
+If the data directory is not accessible:
+
+```bash
+# Check permissions

+# Frequently Asked Questions
+
+Common questions about 9Router.
+
+---
+
+## What is 9Router?
+
+**9Router is an AI model router that maximizes your subscription value and minimizes costs.**
+
+It intelligently routes requests across multiple AI providers using a 3-tier fallback system:
+1. **Subscription tier** - Maximize Claude Code, Codex, Gemini quotas you already pay for
+2. **Cheap tier** - Ultra-cheap alternatives ($0.20-$0.60 per 1M tokens)
+3. **Free tier** - Emergency backup with unlimited free models
+
+**Key benefits:**
+- Never waste subscription quota
+- Automatic fallback when quota exhausted
+- Real-time quota tracking
+- 90% cost savings vs direct API usage
+
+---
+
+## How does pricing work?
+
+**9Router uses a 3-tier pricing strategy:**
+
+### Tier 1: Subscription (Maximize First)
+- **Claude Code** (Pro/Max): $20-100/month - 5-hour + weekly quota
+- **OpenAI Codex** (Plus/Pro): $20-200/month - 5-hour + weekly quota
+- **Gemini CLI**: FREE - 180K completions/month + 1K/day
+- **GitHub Copilot**: $10-19/month - Monthly reset
+- **Antigravity**: FREE - Similar to Gemini
+
+**Goal:** Use every bit of quota before it resets!
+
+### Tier 2: Cheap (Backup)
+- **GLM-4.7**: $0.60/$2.20 per 1M tokens - Daily reset 10AM
+- **MiniMax M2.1**: $0.20/$1.00 per 1M tokens - 5-hour rolling
+- **Kimi K2**: $9/month flat (10M tokens)
+
+**Goal:** 90% cheaper than ChatGPT API ($20/1M)!
+
+### Tier 3: Free (Emergency)

+See [providers documentation](providers/subscription.md) for details.
+
+---
+
+## Can I use multiple providers?
+
+**Yes! This is 9Router's core feature.**
+
+**Combos allow you to chain multiple providers with automatic fallback:**
+
+```
+Example combo: "premium-coding"
+1. cc/claude-opus-4-5 (Subscription primary)
+2. glm/glm-4.7 (Cheap backup)
+3. if/kimi-k2 (Free emergency)
+
+→ Auto-switches when quota exhausted
+→ Never stops coding
+→ Minimal extra cost
+```
+
+**How to create combos:**
+```
+Dashboard → Combos → Create New
+→ Add models in priority order
+→ Use combo name in CLI: "premium-coding"
+```
+
+**Benefits:**
+- Zero downtime when quota runs out
+- Automatic cost optimization
+- Single model name for all tools
+
+See [combos documentation](features/combos.md) for examples.
+
+---
+
+## How does quota tracking work?
+
+**9Router tracks quota in real-time for all providers:**
+
+**Features:**
+- **Token consumption** - Input/output tokens per request
+- **Reset countdown** - Time until quota refreshes
+- **Usage stats** - Daily/weekly/monthly reports
+- **Cost estimation** - Projected spending (paid tiers)
+- **Quota alerts** - Notifications when quota low
+
+**Quota types:**
+- **5-hour rolling** - Claude Code, Codex, MiniMax
+- **Daily reset** - Gemini CLI (1K/day), GLM (10AM)
+- **Weekly reset** - Claude Code, Codex (additional quota)
+- **Monthly reset** - Gemini CLI (180K), GitHub Copilot (1st)
+
+**View quota:**
+```
+Dashboard → Providers → Quota Tracking
+→ Real-time usage + reset countdown
+```
+
+See [quota tracking documentation](features/quota-tracking.md) for details.
+
+---
+
+## Does 9Router work with Cursor?
+
+**Yes, but Cursor requires a cloud endpoint.**
+
+**Problem:** Cursor IDE doesn't support localhost endpoints.
+
+**Solution:** Use 9Router cloud deployment:
+
+```
+Cursor Settings → Models → Advanced:
+  OpenAI API Base URL: https://9router.com/v1
+  OpenAI API Key: [from dashboard]
+  Model: cc/claude-opus-4-5-20251101
+```
+

+```bash
+# Deploy to VPS
+git clone https://github.com/decolua/9router.git
+cd 9router/app
+npm install && npm run build
+npm start
+
+# Configure Nginx reverse proxy
+# Point Cursor to: https://your-domain.com/v1
+```
+
+**Other CLI tools work with localhost:**
+- Cline ✅
+- Claude Desktop ✅

+# Combos - Custom Fallback Chains
+
+Create custom model combinations with automatic fallback. Combos let you define your own routing strategy based on cost, quality, and availability.
+
+---
+
+## What Are Combos?
+
+Combos are **custom fallback chains** that you create in the dashboard. Instead of using a single model, you define a sequence of models that 9Router tries in order.
+
+**Example:**
+```
+Combo name: premium-coding
+Models:
+  1. cc/claude-opus-4-5-20251101 (try first)
+  2. glm/glm-4.7 (if #1 quota exhausted)
+  3. minimax/MiniMax-M2.1 (if #2 quota exhausted)
+```
+
+**Usage in CLI:**
+```
+Model: premium-coding
+```
+
+9Router automatically tries each model in sequence until one succeeds.
+
+---
+
+## Why Use Combos?
+
+### 1. Maximize Subscription Value
+```
+cc/claude-opus → glm/glm-4.7 → if/kimi-k2-thinking
+
+→ Use subscription first, cheap backup, free emergency
+→ Get full value from subscriptions you already pay for
+```
+
+### 2. Minimize Costs
+```
+glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+
+→ Start with cheapest paid option ($0.60/1M)
+→ Fallback to even cheaper ($0.20/1M)
+→ Emergency free tier
+→ Total cost: ~$5-10/month vs $2000 on ChatGPT API
+```
+
+### 3. Ensure 24/7 Availability
+```
+cc/claude-opus → cx/gpt-5.2-codex → glm/glm-4.7 → if/kimi-k2-thinking
+
+→ Always include free tier at the end
+→ Never run out of quota
+→ Code anytime, anywhere
+```
+
+### 4. Optimize for Quality
+```
+cc/claude-opus-4-5 → cx/gpt-5.2-codex → gc/gemini-3-pro
+
+→ Best models first
+→ Fallback to other premium models
+→ Maintain high quality across fallback chain
+```
+
+---
+
+## How to Create Combos
+
+### Step 1: Open Dashboard
+
+```
+http://localhost:20128
+→ Login with your password
+```
+
+### Step 2: Navigate to Combos
+
+```
+Dashboard → Combos → Create New Combo
+```
+
+### Step 3: Configure Combo
+
+**Combo Name:**
+```
+premium-coding
+```
+
+**Description (optional):**
+```
+Subscription first, cheap backup, free emergency
+```
+
+**Select Models:**
+```
+1. cc/claude-opus-4-5-20251101
+2. glm/glm-4.7
+3. minimax/MiniMax-M2.1
+```
+
+**Drag to reorder** - Priority from top to bottom.
+
+### Step 4: Save
+
+```
+Click "Save Combo"
+→ Combo appears in model list
+```
+
+### Step 5: Use in CLI
+
+```
+Cursor/Cline/Any tool:
+  Model: premium-coding
+```
+
+---
+
+## Example Combos
+
+### Example 1: Premium Coding (Subscription → Cheap → Free)
+
+**Goal**: Maximize subscription value, minimize extra costs.
+
+```
+Dashboard → Combos → Create New
+
+Name: premium-coding
+Models:
+  1. cc/claude-opus-4-5-20251101
+  2. glm/glm-4.7
+  3. minimax/MiniMax-M2.1
+```
+
+**Usage:**
+```
+Cursor IDE:
+  Model: premium-coding
+```
+
+**Behavior:**
+```
+Morning (fresh quota):
+  Request → cc/claude-opus-4-5 ✅
+
+Afternoon (Claude quota out):
+  Request → glm/glm-4.7 ✅ (auto switched)
+
+Evening (GLM quota out):
+  Request → minimax/MiniMax-M2.1 ✅ (auto switched)
+```
+
+**Monthly cost (100M tokens):**
+```
+80M via Claude Code: $0 (subscription)
+15M via GLM: $9
+5M via MiniMax: $1
+Total: $10 + your subscription
+```
+
+**Savings**: ~99% vs ChatGPT API ($2000).
+
+---
+
+### Example 2: Budget Combo (Cheap → Free)
+
+**Goal**: Minimize costs, use free tier as backup.
+
+```
+Dashboard → Combos → Create New
+
+Name: budget-combo
+Models:
+  1. glm/glm-4.7
+  2. minimax/MiniMax-M2.1
+  3. if/kimi-k2-thinking
+```
+
+**Usage:**
+```
+Cline:
+  Provider: OpenAI Compatible
+  Base URL: http://localhost:20128/v1
+  Model: budget-combo
+```
+
+**Behavior:**
+```
+Request → glm/glm-4.7
+  ✅ Daily quota available → Use GLM ($0.60/1M)
+  ❌ Quota exhausted → Try MiniMax ($0.20/1M)
+  ❌ MiniMax quota out → Use iFlow (FREE)
+```
+
+**Monthly cost (100M tokens):**
+```
+70M via GLM: $42
+20M via MiniMax: $4
+10M via iFlow: $0
+Total: $46 vs $2000 on ChatGPT API
+```
+
+**Savings**: 97%.
+
+---
+
+### Example 3: Free Combo (Zero Cost)
+
+**Goal**: 100% free, no costs ever.
+
+```
+Dashboard → Combos → Create New
+
+Name: free-combo
+Models:
+  1. if/kimi-k2-thinking
+  2. qw/qwen3-coder-plus
+  3. kr/claude-sonnet-4.5
+```
+
+**Usage:**
+```
+Claude Desktop:
+  Model: free-combo
+```
+
+**Behavior:**
+```
+Request → if/kimi-k2-thinking
+  ✅ Available → Use iFlow
+  ❌ Error → Try Qwen
+  ❌ Error → Try Kiro
+```
+
+**Monthly cost:**
+```
+100M tokens via free providers: $0
+Total: $0 forever
+```
+
+**Use case**: Personal projects, learning, experimentation.
+
+---
+
+### Example 4: Quality First (Premium Models Only)
+
+**Goal**: Best quality, no cheap fallback.
+
+```
+Dashboard → Combos → Create New
+
+Name: quality-first
+Models:
+  1. cc/claude-opus-4-5-20251101
+  2. cx/gpt-5.2-codex
+  3. gc/gemini-3-pro-preview
+```
+
+**Usage:**
+```
+Codex CLI:
+  export OPENAI_BASE_URL="http://localhost:20128"
+  Model: quality-first
+```
+
+**Behavior:**
+```
+Request → cc/claude-opus-4-5
+  ❌ Quota out → cx/gpt-5.2-codex
+  ❌ Quota out → gc/gemini-3-pro-preview
+  ❌ All out → Return error (no cheap fallback)
+```
+
+**Use case**: Critical production code, complex refactoring.
+
+---
+
+### Example 5: Multi-Subscription (Maximize All)
+
+**Goal**: Use all subscriptions before paying extra.
+
+```
+Dashboard → Combos → Create New
+
+Name: multi-sub
+Models:
+  1. gc/gemini-3-flash-preview (FREE 180K/month)
+  2. cc/claude-opus-4-5-20251101 (Pro subscription)
+  3. cx/gpt-5.2-codex (Plus subscription)
+  4. gh/gpt-5 (Copilot subscription)
+  5. glm/glm-4.7 (Cheap backup)
+  6. if/kimi-k2-thinking (Free emergency)
+```
+
+**Monthly cost (200M tokens):**
+```
+50M via Gemini CLI: $0 (free tier)
+80M via Claude Code: $0 (subscription)
+40M via Codex: $0 (subscription)
+20M via Copilot: $0 (subscription)
+8M via GLM: $4.80
+2M via iFlow: $0
+Total: $4.80 + existing subscriptions
+```
+
+**Result**: Use 190M tokens from subscriptions, only $4.80 extra.
+
+---
+
+### Example 6: Quota Reset Optimization
+
+**Goal**: Distribute usage based on reset times.
+
+```
+Dashboard → Combos → Create New
+
+Name: reset-optimized
+Models:
+  1. cc/claude-opus-4-5 (5h reset, use morning)
+  2. gc/gemini-3-flash (1K/day, use afternoon)
+  3. glm/glm-4.7 (daily 10AM reset, use evening)
+  4. minimax/MiniMax-M2.1 (5h rolling, use night)
+  5. if/kimi-k2-thinking (unlimited, emergency)
+```
+
+**Daily routine:**
+```
+08:00 - 13:00: Claude Code (fresh 5h quota)
+13:00 - 18:00: Gemini CLI (1K/day quota)
+18:00 - 22:00: GLM (resets 10AM next day)
+22:00 - 08:00: MiniMax (5h rolling) or iFlow
+```
+
+**Result**: Code 24/7 with minimal costs.

+      {"role": "user", "content": "Write a function to..."}
+    ],
+    "stream": true
+  }'
+```
+
+---
+
+## Best Practices
+
+### 1. Always Include Free Tier
+
+```
+✅ Good:
+cc/claude-opus → glm/glm-4.7 → if/kimi-k2-thinking
+
+❌ Bad:
+cc/claude-opus → glm/glm-4.7
+(no free fallback, can run out of quota)
+```
+
+**Why**: Ensures 24/7 availability, never blocked by quota.
+
+### 2. Order by Cost (Cheap to Expensive)
+
+```
+✅ Good:
+glm/glm-4.7 → minimax/MiniMax-M2.1 → cc/claude-opus
+
+❌ Bad:
+cc/claude-opus → glm/glm-4.7
+(wastes subscription quota on simple tasks)
+```
+
+**Exception**: If you want to maximize subscription value, put subscription first.
+
+### 3. Match Quality Requirements
+
+```
+For production code:
+cc/claude-opus → cx/gpt-5.2-codex → glm/glm-4.7
+
+For quick tasks:
+glm/glm-4.7 → if/kimi-k2-thinking
+
+For experimentation:
+if/kimi-k2-thinking → qw/qwen3-coder-plus
+```
+
+### 4. Consider Quota Reset Times
+
+```
+Morning combo (fresh quotas):
+cc/claude-opus → cx/gpt-5.2-codex
+
+Evening combo (quotas likely exhausted):
+glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+```
+
+### 5. Create Multiple Combos for Different Use Cases
+
+```
+premium-coding: For complex tasks
+budget-combo: For simple tasks
+free-combo: For experimentation
+quality-first: For production code
+```
+
+**Switch between combos** based on task requirements.
+
+### 6. Monitor Combo Performance
+
+```
+Dashboard → Analytics → Combo Usage:
+  premium-coding:
+    80% via cc/claude-opus (good, using subscription)
+    15% via glm/glm-4.7 (acceptable backup)
+    5% via minimax (rare fallback)
+```
+
+**Optimize**: If too much fallback usage, increase primary quota or reorder models.
+
+---
+
+## Advanced Configuration
+
+### Set Budget Limits per Combo
+
+```
+Dashboard → Combos → Edit → Budget:
+  Daily limit: $5
+  Monthly limit: $50
+```
+
+When limit reached, 9Router skips paid models and uses free tier only.
+
+### Enable/Disable Models in Combo
+
+```
+Dashboard → Combos → Edit → Models:
+  ✅ cc/claude-opus-4-5 (enabled)
+  ❌ glm/glm-4.7 (temporarily disabled)
+  ✅ if/kimi-k2-thinking (enabled)
+```
+
+**Use case**: Temporarily disable expensive models without deleting combo.
+
+### Clone Existing Combo
+
+```
+Dashboard → Combos → Clone "premium-coding"
+→ Creates copy with "-copy" suffix
+→ Modify and save as new combo
+```
+
+**Use case**: Create variations for different scenarios.
+
+---
+
+## Troubleshooting
+
+**Issue: Combo not appearing in model list**
+
+**Solution:**
+1. Refresh dashboard
+2. Check combo is saved (green checkmark)
+3. Restart CLI tool to refresh model list
+
+**Issue: Combo always uses last model (free tier)**
+
+**Solution:**
+1. Check quota for primary models (Dashboard → Quota)
+2. Verify API keys are valid (Dashboard → Providers)
+3. Check budget limits not exceeded
+
+**Issue: Combo costs more than expected**
+
+**Solution:**
+1. Dashboard → Analytics → Review combo usage
+2. Check if primary models are quota-exhausted
+3. Reorder models (put cheaper first)
+4. Set budget limits

+## Alerts & Notifications
+
+### Quota Alerts
+
+```
+Dashboard → Settings → Alerts
+
+Quota warnings:
+  ✅ Alert at 80% quota used
+  ✅ Alert at 90% quota used
+  ✅ Alert when quota exhausted
+  ✅ Notify when quota resets
+
+Delivery:
+  ✅ Dashboard notification
+  ✅ Email (optional)
+  ✅ Webhook (optional)
+```
+
+**Example notifications:**
+```
+⚠️ Claude Code quota 80% used
+   2.5h remaining (resets in 1h 30m)
+   
+⚠️ GLM-4.7 quota 90% used
+   1M tokens remaining (resets in 5h)
+   
+✅ Gemini CLI quota reset
+   1,000 requests available (daily limit)
+```
+
+### Budget Alerts
+
+```
+Dashboard → Settings → Budget Alerts
+
+Daily budget: $5
+  ✅ Alert at 80% ($4)
+  ✅ Alert at 100% ($5)
+  ✅ Auto-switch to free tier when exceeded
+
+Monthly budget: $150
+  ✅ Alert at 50% ($75)
+  ✅ Alert at 80% ($120)
+  ✅ Alert at 100% ($150)
+```
+
+**Example notifications:**
+```
+⚠️ Daily budget 80% used
+   $4.00 / $5.00 spent today
+   
+⚠️ Monthly budget 50% reached
+   $75 / $150 spent this month
+   Projected: $135 (within budget)
+   
+🚨 Daily budget exceeded
+   $5.20 / $5.00 spent today
+   Auto-switched to free tier
+```
+
+### Cost Anomaly Detection
+
+```
+Dashboard → Settings → Anomaly Detection
+
+✅ Detect unusual spending patterns
+✅ Alert on cost spikes (>2× daily average)
+✅ Warn on quota exhaustion patterns
+
+Example alert:
+⚠️ Cost spike detected
+   Today: $12.50 (2.5× daily average)
+   Reason: High GLM-4.7 usage (20M tokens)
+   Suggestion: Check if primary models quota-exhausted
+```
+
+---
+
+## Best Practices
+
+### 1. Monitor Quota Daily
+
+```
+Daily routine:
+1. Check dashboard quota overview (30 seconds)
+2. Review reset times
+3. Plan usage around quota availability
+```
+
+**Example:**
+```
+Morning check:
+  ✅ Claude Code: 5h available (fresh reset)
+  ✅ Gemini CLI: 1K requests available
+  ⚠️ GLM-4.7: 2M tokens left (resets 10AM)
+  
+Action: Use Claude Code for morning work
+```
+
+### 2. Set Budget Limits
+
+```
+Dashboard → Settings → Budget:
+  Daily: $5 (prevents overspending)
+  Monthly: $150 (aligns with budget)
+```
+
+**Result**: Auto-switch to free tier when limit reached.
+
+### 3. Optimize Combo Usage
+
+```
+Dashboard → Analytics → Combos:
+  Review which models are used most
+  Adjust combo order to minimize costs
+```
+
+**Example:**
+```
+Current: cc/claude-opus → glm/glm-4.7
+  80% via Claude (good)
+  20% via GLM ($12/month)
+
+Optimized: gc/gemini-3-flash → cc/claude-opus → glm/glm-4.7
+  50% via Gemini (free)
+  40% via Claude (subscription)
+  10% via GLM ($6/month)
+  
+Savings: $6/month
+```
+
+### 4. Track Reset Times
+
+```
+Dashboard → Quota → Reset Schedule:
+  Claude Code: 5h rolling + Weekly Monday
+  Gemini CLI: Daily 00:00 UTC + Monthly 1st
+  GLM-4.7: Daily 10:00 AM Beijing Time
+  MiniMax: Rolling 5h window
+```
+
+**Strategy**: Use providers when quota is fresh.
+
+### 5. Review Monthly Reports
+
+```
+Dashboard → Analytics → Monthly Report:
+  Total tokens: 1.5B
+  Total cost: $120
+  Savings: 97% vs ChatGPT API
+  
+Insights:
+  - 60% usage via subscriptions ($0)
+  - 30% via GLM ($90)
+  - 10% via free tier ($0)
+  
+Optimization:
+  - Increase Gemini CLI usage (free)
+  - Reduce GLM usage (expensive)
+```

+# Smart Routing & Auto Fallback
+
+9Router automatically routes your requests through the best available provider using a 3-tier fallback system. Never stop coding due to quota limits or rate limiting.
+
+---
+
+## How It Works
+
+9Router uses intelligent routing to maximize your existing subscriptions, minimize costs, and ensure 24/7 availability:
+
+```
+Request → 9Router → Check Tier 1 (Subscription)
+                     ↓ quota exhausted
+                     Check Tier 2 (Cheap)
+                     ↓ budget limit
+                     Check Tier 3 (Free)
+                     ↓
+                     Response
+```
+
+### 3-Tier Fallback System
+
+**Tier 1: SUBSCRIPTION (Primary)**
+- Claude Code (Pro/Max)
+- OpenAI Codex (Plus/Pro)
+- Gemini CLI (FREE 180K/month)
+- GitHub Copilot
+- Antigravity (Google)
+
+**Goal**: Maximize value from subscriptions you already pay for.
+
+**Tier 2: CHEAP (Backup)**
+- GLM-4.7 ($0.60/1M input)
+- MiniMax M2.1 ($0.20/1M input)
+- Kimi K2 ($9/month flat)
+
+**Goal**: Ultra-cheap backup when subscription quota runs out (~90% cheaper than ChatGPT API).
+
+**Tier 3: FREE (Emergency)**
+- iFlow (8 models)
+- Qwen (3 models)
+- Kiro (Claude FREE)
+
+**Goal**: Zero-cost fallback for unlimited coding.
+
+---
+
+## Automatic Switching
+
+9Router monitors quota in real-time and switches providers automatically:
+
+### Scenario 1: Subscription Quota Exhausted
+
+```
+User request → cc/claude-opus-4-5
+               ↓ quota exhausted (5-hour limit reached)
+               Auto switch → glm/glm-4.7
+               ↓ daily quota exhausted
+               Auto switch → minimax/MiniMax-M2.1
+               ↓ 5-hour quota exhausted
+               Auto switch → if/kimi-k2-thinking (FREE)
+               ↓
+               Response delivered ✅
+```
+
+**Result**: Zero downtime, seamless experience.
+
+### Scenario 2: Rate Limiting
+
+```
+User request → cx/gpt-5.2-codex
+               ↓ rate limited (too many requests)
+               Auto switch → glm/glm-4.7
+               ↓
+               Response delivered ✅
+```
+
+### Scenario 3: Provider Unavailable
+
+```
+User request → cc/claude-opus-4-5
+               ↓ provider error (503)
+               Auto switch → next available model
+               ↓
+               Response delivered ✅
+```
+
+---
+
+## Model Selection Logic
+
+9Router selects the best model based on:
+
+1. **Quota availability** - Check if provider has remaining quota
+2. **Cost tier** - Prefer subscription → cheap → free
+3. **Reset timing** - Consider when quota resets
+4. **Provider health** - Skip providers with errors
+
+### Priority Order Example
+
+For a request to `cc/claude-opus-4-5`:
+
+```
+1. Check Claude Code quota
+   ✅ Available → Use cc/claude-opus-4-5
+   ❌ Exhausted → Continue to step 2
+
+2. Check fallback tier (if configured)
+   ✅ GLM quota available → Use glm/glm-4.7
+   ❌ Exhausted → Continue to step 3
+
+3. Check free tier
+   ✅ iFlow available → Use if/kimi-k2-thinking
+   ❌ All exhausted → Return quota error
+```
+
+---
+
+## Configuration Options
+
+### Dashboard Settings
+
+**1. Enable/Disable Auto Fallback**
+
+```
+Dashboard → Settings → Smart Routing
+→ Toggle "Auto Fallback" ON/OFF
+```
+
+- **ON** (default): Automatic tier switching
+- **OFF**: Strict mode, return error if primary model unavailable
+
+**2. Set Budget Limits**
+
+```
+Dashboard → Settings → Budget Control
+→ Daily limit: $5
+→ Monthly limit: $50
+```
+
+When budget reached, 9Router automatically switches to free tier.
+
+**3. Configure Fallback Order**
+
+```
+Dashboard → Settings → Fallback Priority
+→ Drag to reorder providers within each tier
+```
+
+Example custom order:
+```
+Tier 1: Gemini CLI → Claude Code → Codex
+Tier 2: MiniMax → GLM → Kimi
+Tier 3: iFlow → Kiro → Qwen
+```
+
+**4. Quota Reset Notifications**
+
+```
+Dashboard → Settings → Notifications
+→ Email when quota resets
+→ Alert when 80% quota used
+```
+
+---
+
+## Examples
+
+### Example 1: Basic Auto Fallback
+
+**Setup:**
+```
+Model: cc/claude-opus-4-5-20251101
+Fallback: Auto (default 3-tier)
+```
+
+**Behavior:**
+```
+Morning (fresh quota):
+  Request → cc/claude-opus-4-5 ✅
+
+Afternoon (quota exhausted):
+  Request → glm/glm-4.7 ✅ (auto switched)
+
+Evening (GLM quota out):
+  Request → minimax/MiniMax-M2.1 ✅ (auto switched)
+
+Late night (all paid quota out):
+  Request → if/kimi-k2-thinking ✅ (free tier)
+```
+
+**Cost**: ~$5-10/month extra (mostly covered by subscription).
+
+### Example 2: Budget-Conscious Routing
+
+**Setup:**
+```
+Dashboard → Settings:
+  Daily budget: $2
+  Monthly budget: $20
+  Fallback: Enabled
+```
+
+**Behavior:**
+```
+Day 1-15 (within budget):
+  Requests → glm/glm-4.7 (cheap tier)
+  Cost: $1.50/day
+
+Day 16 (budget reached):
+  Requests → if/kimi-k2-thinking (free tier)
+  Cost: $0
+
+Next month (budget resets):
+  Requests → glm/glm-4.7 again
+```
+
+**Result**: Never exceed $20/month, always available.
+
+### Example 3: Subscription-Only Mode
+
+**Setup:**
+```
+Dashboard → Settings:
+  Auto Fallback: OFF
+  Strict mode: ON
+```
+
+**Behavior:**
+```
+Request → cc/claude-opus-4-5
+  ✅ Quota available → Success
+  ❌ Quota exhausted → Return error (no fallback)
+```
+
+**Use case**: When you only want to use paid subscriptions, no extra costs.
+
+### Example 4: Free-Only Mode
+
+**Setup:**
+```
+Model: if/kimi-k2-thinking
+Fallback: qw/qwen3-coder-plus → kr/claude-sonnet-4.5
+```
+
+**Behavior:**
+```
+All requests → Free tier only
+Cost: $0 forever
+```
+
+**Use case**: Personal projects, learning, experimentation.
+
+---
+
+## Best Practices
+
+### 1. Maximize Subscription Value
+
+```
+Strategy:
+- Set subscription models as Tier 1
+- Monitor quota usage in dashboard
+- Use cheap tier only when subscription exhausted
+```
+
+**Example combo:**
+```
+cc/claude-opus-4-5 → glm/glm-4.7 → if/kimi-k2-thinking
+```
+
+### 2. Optimize for Cost
+
+```
+Strategy:
+- Use Gemini CLI free tier first (180K/month)
+- Fallback to GLM/MiniMax (ultra-cheap)
+- Emergency: iFlow (free)
+```
+
+**Example combo:**
+```
+gc/gemini-3-flash-preview → glm/glm-4.7 → if/kimi-k2-thinking
+```
+
+### 3. Optimize for Quality
+
+```
+Strategy:
+- Use best models (Claude Opus, GPT-5.2)
+- Fallback to good cheap models (GLM-4.7)
+- Last resort: Free tier
+```
+
+**Example combo:**
+```
+cc/claude-opus-4-5 → cx/gpt-5.2-codex → glm/glm-4.7
+```
+
+### 4. 24/7 Availability
+
+```
+Strategy:
+- Always include free tier in fallback
+- Monitor quota reset times
+- Distribute usage across providers
+```
+
+**Example combo:**
+```
+cc/claude-opus-4-5 → glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+```
+
+**Result**: Never run out of quota, code anytime.
+
+---
+
+## Quota Reset Strategy
+
+Plan your usage around quota reset times:
+
+| Provider | Quota Reset | Strategy |
+|----------|-------------|----------|
+| **Claude Code** | 5-hour + weekly | Use in morning, fresh quota |
+| **Codex** | 5-hour + weekly | Use after Claude quota out |
+| **Gemini CLI** | Daily (1K) + Monthly (180K) | Use throughout day |
+| **GLM-4.7** | Daily 10:00 AM | Use evening, resets next morning |
+| **MiniMax M2.1** | 5-hour rolling | Use anytime, tracks rolling window |
+| **iFlow/Qwen/Kiro** | No limit | Emergency backup |
+
+**Daily routine example:**
+```
+08:00 - 13:00: Claude Code (fresh 5h quota)
+13:00 - 18:00: Gemini CLI (1K/day quota)
+18:00 - 22:00: GLM-4.7 (cheap, resets 10AM)
+22:00 - 08:00: MiniMax or iFlow (5h rolling or free)
+```
+
+---
+
+## Monitoring & Alerts
+
+### Dashboard Quota Tracker
+
+```
+Dashboard → Quota Overview:
+  Claude Code: 2.5h / 5h remaining (50%)
+  Gemini CLI: 450 / 1000 requests today
+  GLM-4.7: 5M / 10M tokens (resets in 8h)
+  MiniMax: 3M / 5M tokens (rolling 5h)
+```
+
+### Real-Time Notifications
+
+```
+Dashboard → Notifications:
+  ⚠️ Claude Code quota 80% used (1h remaining)
+  ✅ GLM-4.7 quota reset (10M tokens available)
+  💰 Daily budget 50% used ($2.50 / $5)
+```
+
+### Usage Analytics
+
+```
+Dashboard → Analytics:
+  Today: 50M tokens
+    - 30M via Claude Code (subscription)
+    - 15M via GLM-4.7 ($9)
+    - 5M via iFlow (free)
+  
+  Cost: $9 (vs $1000 on ChatGPT API)
+  Savings: 99%
+```
+
+---
+
+## Troubleshooting
+
+**Issue: "All providers quota exhausted"**
+
+**Solution:**
+1. Check dashboard quota tracker
+2. Wait for quota reset (see countdown)
+3. Add free tier to fallback chain
+4. Or increase budget limit
+
+**Issue: "Too many fallback switches"**
+
+**Solution:**
+1. Check if primary provider is down
+2. Increase quota limits (upgrade subscription)
+3. Use cheaper primary model (GLM instead of Claude)
+
+**Issue: "Unexpected costs"**
+
+**Solution:**
+1. Dashboard → Analytics → Review usage
+2. Set daily/monthly budget limits
+3. Switch to free tier for non-critical tasks
+4. Use combos with free fallback

+🎉 **Dashboard opens automatically** at `http://localhost:20128`
+
+- Default password: `123456` (change in dashboard)
+- API key generated automatically
+- Ready to connect providers
+
+### 3. Connect Providers
+
+You have 3 ways to connect providers:
+
+#### Option A: OAuth (Subscription Providers)
+
+**Best for:** Claude Code, Codex, Gemini CLI, GitHub Copilot
+
+```
+Dashboard → Providers → Connect [Provider]
+→ OAuth login → Auto token refresh
+→ Quota tracking enabled
+```
+
+**Example: Claude Code**
+1. Click "Connect Claude Code"
+2. Login with your Claude account
+3. Authorize 9Router
+4. ✅ Done! Use model: `cc/claude-opus-4-5-20251101`
+
+#### Option B: API Key (Cheap Providers)
+
+**Best for:** GLM, MiniMax, Kimi, OpenRouter
+
+```
+Dashboard → Providers → Add API Key
+→ Select provider
+→ Paste API key
+→ Save
+```
+
+**Example: GLM-4.7**
+1. Sign up at [Zhipu AI](https://open.bigmodel.cn/)
+2. Get API key from Coding Plan
+3. Dashboard → Add API Key → Provider: `glm` → Paste key
+4. ✅ Done! Use model: `glm/glm-4.7`
+
+#### Option C: Free Providers (No Cost)
+
+**Best for:** iFlow, Qwen, Kiro
+
+```
+Dashboard → Providers → Connect [Free Provider]
+→ Device code or OAuth
+→ Unlimited usage
+```
+
+**Example: iFlow**
+1. Click "Connect iFlow"
+2. Login with iFlow account
+3. Authorize
+4. ✅ Done! Use 8 models: `if/kimi-k2-thinking`, `if/qwen3-coder-plus`, etc.
+
+---
+
+## 4. Use in CLI Tools
+
+Point your coding tool to 9Router:
+
+### Cursor IDE
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [from 9router dashboard]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+### Claude Desktop
+
+Edit `~/.claude/config.json`:
+
+```json
+{
+  "anthropic_api_base": "http://localhost:20128/v1",
+  "anthropic_api_key": "your-9router-api-key"
+}
+```
+
+### Cline / Continue / RooCode
+
+```
+Provider: OpenAI Compatible
+Base URL: http://localhost:20128/v1
+API Key: [from dashboard]
+Model: cc/claude-opus-4-5-20251101
+```
+
+### Codex CLI
+
+```bash
+export OPENAI_BASE_URL="http://localhost:20128"
+export OPENAI_API_KEY="your-9router-api-key"
+
+codex "your prompt"
+```
+
+---
+
+## 5. Create Smart Combos (Optional)
+
+Combos enable automatic fallback between models:
+
+```
+Dashboard → Combos → Create New
+
+Name: premium-coding
+Models:
+  1. cc/claude-opus-4-5-20251101 (Subscription primary)
+  2. glm/glm-4.7 (Cheap backup, $0.6/1M)
+  3. if/kimi-k2-thinking (Free fallback)
+
+Use in CLI: premium-coding
+```
+
+**How it works:**
+1. Tries Claude Opus first (your subscription)
+2. If quota exhausted → GLM-4.7 (ultra-cheap)
+3. If budget limit → iFlow (free)
+4. Zero downtime, automatic switching!
+
+---
+
+## Available Models

+## Cost Optimization Strategy
+
+### Monthly Budget: $10-20/month
+
+```
+1. Use Gemini CLI free tier (180K/month) for quick tasks
+2. Use Claude Code subscription quota fully (you already pay)
+3. Fallback to GLM ($0.6/1M) when quota out
+4. Emergency: MiniMax M2.1 ($0.20/1M) or iFlow (free)
+
+Real example (100M tokens/month):
+  60M via Gemini CLI: $0 (free tier)
+  30M via Claude Code: $0 (subscription you already have)
+  8M via GLM: $4.80
+  2M via MiniMax: $0.40
+  Total: $5.20/month + existing subscriptions
+```
+
+### Quota Reset Strategy
+
+```
+Daily routine:
+1. Morning: Fresh Claude Code quota (5h reset)
+2. Afternoon: Switch to Gemini CLI (1K/day)
+3. Evening: GLM daily quota (reset 10AM next day)
+4. Late night: MiniMax (5h rolling) or iFlow (free)
+
+→ Code 24/7 with minimal extra cost!

+
+## Common Integration Patterns
+
+### Environment Variables
+
+Store credentials securely:
+
+```bash
+# .env file
+ROUTER_API_KEY=your-api-key-from-dashboard
+ROUTER_BASE_URL=http://localhost:20128/v1
+ROUTER_MODEL=cc/claude-sonnet-4-20250514
+```
+
+```python
+import os
+from openai import OpenAI
+
+client = OpenAI(
+    api_key=os.getenv("ROUTER_API_KEY"),
+    base_url=os.getenv("ROUTER_BASE_URL")
+)
+```
+
+### Error Handling
+
+```python
+from openai import OpenAI, OpenAIError
+
+client = OpenAI(
+    api_key="your-api-key",
+    base_url="http://localhost:20128/v1"
+)
+
+try:
+    response = client.chat.completions.create(
+        model="cc/claude-sonnet-4-20250514",
+        messages=[{"role": "user", "content": "Hello"}]
+    )
+    print(response.choices[0].message.content)
+except OpenAIError as e:
+    print(f"Error: {e}")
+```
+
+### Retry Logic
+
+```python
+import time
+from openai import OpenAI, RateLimitError
+
+client = OpenAI(
+    api_key="your-api-key",
+    base_url="http://localhost:20128/v1"
+)
+
+def chat_with_retry(prompt, max_retries=3):
+    for attempt in range(max_retries):
+        try:
+            response = client.chat.completions.create(
+                model="cc/claude-sonnet-4-20250514",
+                messages=[{"role": "user", "content": prompt}]
+            )
+            return response.choices[0].message.content
+        except RateLimitError:
+            if attempt < max_retries - 1:
+                time.sleep(2 ** attempt)  # Exponential backoff
+            else:

+---
+
+## Usage Example
+
+### Cursor IDE Setup
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [from 9router dashboard]
+  Model: glm/glm-4.7
+```
+
+### Create Combo (Recommended)
+
+```
+Dashboard → Combos → Create New
+
+Name: cheap-backup
+Models:
+  1. cc/claude-opus-4-5 (Subscription primary)
+  2. glm/glm-4.7 (Cheap backup, daily reset)
+  3. minimax/MiniMax-M2.1 (Cheapest fallback)
+  4. if/kimi-k2-thinking (FREE emergency)
+
+Use in CLI: cheap-backup
+```
+
+**Result:** Subscription → Cheap → Cheapest → Free
+
+---
+
+## Cost Optimization
+
+### Strategy 1: Daily Reset Routine
+
+```
+Morning (10AM): Fresh GLM quota
+→ Use GLM for heavy tasks
+→ Save subscription quota
+
+Afternoon: Subscription quota
+→ Use Claude/Codex for complex tasks
+
+Evening: MiniMax (5h reset)
+→ Cheap fallback for late work
+
+Night: Free tier (iFlow)
+→ Zero cost emergency backup
+```
+
+### Strategy 2: Budget-First
+
+```
+Set monthly budget: $20
+
+Allocation:
+- $9 Kimi K2 (10M tokens flat)
+- $6 GLM daily quota (10M tokens)
+- $5 MiniMax overflow (25M tokens)
+
+Total: 45M tokens for $20
+vs 1M tokens for $20 on ChatGPT API!
+```
+
+### Strategy 3: Maximize Subscriptions First
+
+```
+Priority:
+1. Gemini CLI (180K/month FREE)
+2. Claude Code (subscription you already pay)
+3. GLM-4.7 (cheap backup, $0.6/1M)
+4. MiniMax M2.1 (cheapest, $0.2/1M)
+5. iFlow (FREE emergency)
+
+Monthly cost example (100M tokens):
+- 60M via Gemini CLI: $0 (free)
+- 30M via Claude Code: $0 (subscription)
+- 8M via GLM: $4.80
+- 2M via MiniMax: $0.40
+Total: $5.20/month!
+```
+
+---
+
+## Real-World Examples
+
+### Example 1: Heavy Coding Month (100M tokens)
+
+```
+Breakdown:
+- 60M via subscription (Claude/Codex): $0 extra
+- 30M via GLM-4.7: $18
+- 10M via MiniMax M2.1: $2
+
+Total: $20/month
+vs $2000 on ChatGPT API!
+
+Savings: 99% cheaper!
+```
+
+### Example 2: Budget Coder ($10/month)
+
+```
+Strategy:
+- $9 Kimi K2 (10M tokens)
+- $1 MiniMax overflow (5M tokens)
+
+Total: 15M tokens for $10
+vs 0.5M tokens for $10 on ChatGPT API!
+
+30× more tokens!
+```
+
+### Example 3: Freelancer (Variable Usage)
+
+```
+Light month (20M tokens):
+- 15M via subscription: $0
+- 5M via GLM: $3
+Total: $3
+
+Heavy month (150M tokens):
+- 60M via subscription: $0
+- 60M via GLM: $36
+- 30M via MiniMax: $6
+Total: $42
+
+Average: $22.50/month
+vs $3400 on ChatGPT API!
+```
+
+---
+
+## Best Practices
+
+### 1. Track Daily Quota
+
+```
+Dashboard shows:
+- GLM quota: 75% used (reset in 6h)
+- MiniMax quota: 50% used (reset in 2h)
+- Kimi quota: 8M/10M used (reset in 15 days)
+
+Plan heavy tasks around reset times!
+```
+
+### 2. Use Coding Plan (GLM)
+
+```
+Standard: 1× quota
+Coding Plan: 3× quota (same price!)
+
+→ Always choose Coding Plan
+```
+
+### 3. Combine with Free Tier
+
+```
+Combo:
+1. gc/gemini-3-flash (FREE primary)
+2. glm/glm-4.7 (cheap backup)
+3. minimax/MiniMax-M2.1 (cheapest)
+4. if/kimi-k2-thinking (FREE emergency)
+
+Result: Minimize costs, maximize uptime
+```
+
+### 4. Set Budget Alerts
+
+```
+Dashboard → Settings → Budget Alerts
+
+Daily: $2 limit
+Weekly: $10 limit
+Monthly: $30 limit
+
+→ Auto switch to free tier when limit reached
+```
+
+---
+
+## Troubleshooting
+
+### "Quota exhausted"
+
+**Solution:**
+- GLM: Wait until 10:00 AM Beijing time
+- MiniMax: Wait 5 hours from first use
+- Kimi: Wait until 1st of next month
+- Use combo fallback to free tier
+
+### "API key invalid"
+
+**Solution:**
+- Check API key copied correctly
+- Verify account has credits
+- Regenerate API key if needed
+
+### "High costs"
+
+**Solution:**
+- Check usage stats in Dashboard
+- Set budget alerts
+- Switch to MiniMax ($0.2/1M cheapest)
+- Use free tier for non-critical tasks
+
+---
+
+## Next Steps
+
+- **Add free fallback:** [Free Providers](./free.md)
+- **Setup subscriptions:** [Subscription Providers](./subscription.md)
+- **Create combos:** Dashboard → Combos → Create New

+## Best Practices
+
+### 1. Use as Emergency Backup
+
+```
+Priority:
+1. Subscription tier (maximize paid quota)
+2. Cheap tier (pennies per 1M tokens)
+3. FREE tier (unlimited, zero cost)
+
+Only use free tier when:
+- Subscription quota exhausted
+- Budget limit reached
+- Testing/non-critical tasks
+```
+
+### 2. Choose Right Model
+
+```
+Complex reasoning: if/kimi-k2-thinking
+Fast coding: qw/qwen3-coder-flash
+Best quality: kr/claude-sonnet-4.5
+Long context: if/minimax-m2
+Vision tasks: qw/vision-model
+```
+
+### 3. Create Free-Only Combo
+
+```
+For zero-cost coding:
+
+Name: zero-cost
+Models:
+  1. kr/claude-sonnet-4.5 (Best quality)
+  2. if/kimi-k2-thinking (Complex tasks)
+  3. qw/qwen3-coder-plus (Fast coding)
+
+Cost: $0 forever!
+```
+
+### 4. Test Before Production
+
+```
+Use free tier to:
+- Test prompts

+```
+
+---
+
+## Cost Comparison
+
+### Scenario: 100M tokens/month
+
+**Option 1: ChatGPT API Only**
+```
+100M × $20/1M = $2,000/month
+```
+
+**Option 2: 9Router Free Tier Only**
+```
+100M via free tier = $0/month
+Savings: $2,000/month (100%)
+```
+
+**Option 3: 9Router Complete Strategy**
+```
+60M via Gemini CLI (FREE): $0
+30M via Claude Code (subscription): $0 extra
+8M via GLM (cheap): $4.80
+2M via iFlow (FREE): $0
+Total: $4.80/month + subscriptions you already have
+Savings: $1,995/month (99.76%)
+```
+
+---
+
+## Troubleshooting
+
+### "OAuth failed"
+
+**Solution:**
+- Check internet connection
+- Try different browser
+- Clear browser cache
+- Reconnect in dashboard
+
+### "Model not available"
+
+**Solution:**
+- Check provider connected in dashboard
+- Verify OAuth token valid
+- Reconnect provider if needed
+
+### "Slow responses"
+
+**Solution:**
+- Free tier may have lower priority
+- Use during off-peak hours
+- Switch to different free provider
+- Upgrade to cheap tier for speed
+
+---
+
+## Limitations
+
+### Free Tier Considerations
+
+- **Speed** - May be slower than paid tiers
+- **Priority** - Lower priority during peak hours
+- **Rate limits** - Possible rate limiting (but unlimited quota)
+- **Availability** - May have occasional downtime
+
+**Solution:** Use 3-tier fallback strategy for reliability!
+
+---
+
+## Next Steps
+
+- **Setup subscriptions:** [Subscription Providers](./subscription.md)
+- **Add cheap backup:** [Cheap Providers](./cheap.md)
+- **Create combos:** Dashboard → Combos → Create New
+- **Start coding:** Use `complete-fallback` combo for maximum reliability

+## Usage Example
+
+### Cursor IDE Setup
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [from 9router dashboard]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+### Create Combo (Recommended)
+
+```
+Dashboard → Combos → Create New
+
+Name: premium-coding
+Models:
+  1. gc/gemini-3-flash-preview (FREE, use first)
+  2. cc/claude-opus-4-5-20251101 (Subscription)
+  3. cx/gpt-5.2-codex (Subscription backup)
+
+Use in CLI: premium-coding
+```
+
+**Result:** Maximize free tier → Use subscription → Auto fallback
+
+---
+
+## Quota Tracking
+
+9Router tracks quota in real-time:
+
+- **Token consumption** - Input/output tokens per request
+- **Reset countdown** - Time until next quota reset
+- **Usage percentage** - How much quota used
+- **Auto fallback** - Switch to next tier when exhausted
+
+**Dashboard view:**
+
+```
+Claude Code Pro
+├─ Quota: 75% used
+├─ Reset: 2h 15m (5-hour)
+├─ Weekly reset: 3 days
+└─ Fallback: glm/glm-4.7 (cheap tier)
+```
+
+---
+
+## Best Practices
+
+### 1. Use Free Tier First
+
+```
+Priority:
+1. Gemini CLI (180K/month FREE)
+2. Antigravity (FREE Claude)
+3. Claude Code/Codex (paid subscriptions)
+```
+
+### 2. Track Quota Daily
+
+- Check dashboard every morning
+- Plan heavy tasks around quota resets
+- Use cheap/free tier for non-critical tasks
+
+### 3. Create Smart Combos
+
+```
+Example combo:
+1. gc/gemini-3-flash-preview (FREE primary)
+2. cc/claude-opus-4-5 (Complex tasks)
+3. glm/glm-4.7 (Cheap backup)
+4. if/kimi-k2-thinking (FREE fallback)
+```
+
+### 4. Optimize by Time
+
+```
+Morning: Fresh 5-hour quota (Claude/Codex)
+Afternoon: Gemini CLI (1K/day)
+Evening: Subscription quota
+Night: Cheap/free tier
+```
+
+---
+
+## Troubleshooting
+
+### "Quota exhausted"
+
+**Solution:**
+- Check dashboard quota tracker
+- Wait for reset (5-hour or daily)
+- Use combo fallback to cheap/free tier
+
+### "OAuth token expired"
+
+**Solution:**
+- Auto-refreshed by 9Router
+- If issues: Dashboard → Provider → Reconnect
+
+### "Rate limiting"
+
+**Solution:**
+- Subscription quota out
+- Add fallback: `cc/claude-opus → glm/glm-4.7`
+- Use free tier: `if/kimi-k2-thinking`
+
+---
+
+## Next Steps
+
+- **Setup cheap backup:** [Cheap Providers](./cheap.md)
+- **Add free fallback:** [Free Providers](./free.md)
+- **Create combos:** Dashboard → Combos → Create New

+# Troubleshooting
+
+Common issues and solutions when using 9Router.
+
+---
+
+## "Language model did not provide messages"
+
+**Problem:** Request fails with empty response or error message.
+
+**Causes:**
+- Provider quota exhausted
+- API key invalid or expired
+- Model not available
+
+**Solutions:**
+
+1. **Check quota status:**
+   ```
+   Dashboard → Providers → View quota tracker
+   ```
+   If quota is exhausted, wait for reset or switch provider.
+
+2. **Use combo fallback:**
+   ```
+   Dashboard → Combos → Create fallback chain
+   Example: cc/claude-opus → glm/glm-4.7 → if/kimi-k2
+   ```
+
+3. **Verify provider connection:**
+   ```
+   Dashboard → Providers → Reconnect if needed
+   ```
+
+---
+
+## Rate Limiting
+
+**Problem:** "Rate limit exceeded" or "Too many requests" errors.
+
+**Causes:**
+- Subscription quota depleted (5-hour/daily/weekly limits)
+- API rate limits hit
+- Too many concurrent requests
+
+**Solutions:**
+
+1. **Check reset time:**
+   ```
+   Dashboard → Quota Tracking → View reset countdown
+   ```
+
+2. **Switch to cheap tier:**
+   ```
+   Use: glm/glm-4.7 ($0.6/1M tokens)
+        minimax/MiniMax-M2.1 ($0.20/1M tokens)
+   ```
+
+3. **Add fallback combo:**
+   ```
+   Dashboard → Combos → Add backup models
+   Primary: cc/claude-opus (subscription)
+   Backup: glm/glm-4.7 (cheap)
+   Emergency: if/kimi-k2 (free)
+   ```
+
+---
+
+## OAuth Token Expired
+
+**Problem:** "Unauthorized" or "Token expired" errors.
+
+**Causes:**
+- OAuth token expired (auto-refresh failed)
+- Provider session invalidated
+- Network issues during refresh
+
+**Solutions:**
+
+1. **Auto-refresh (default):**
+   9Router automatically refreshes tokens. Wait 30 seconds and retry.
+
+2. **Manual reconnect:**
+   ```
+   Dashboard → Providers → [Provider Name] → Reconnect
+   → Complete OAuth flow again
+   ```
+
+3. **Check provider status:**
+   Verify provider service is online (Claude Code, Codex, etc.)
+
+---
+
+## High Costs
+
+**Problem:** Unexpected high usage or costs.
+
+**Causes:**
+- Using expensive models unnecessarily
+- No fallback to cheaper tiers
+- Large context windows
+
+**Solutions:**
+
+1. **Check usage stats:**
+   ```
+   Dashboard → Usage Stats → View token consumption
+   → Identify high-cost models
+   ```
+
+2. **Switch to cheaper models:**
+   ```
+   Replace: cc/claude-opus ($20-100/month subscription)
+   With: glm/glm-4.7 ($0.6/1M tokens)
+         minimax/MiniMax-M2.1 ($0.20/1M tokens)
+   ```
+
+3. **Use free tier:**
+   ```
+   if/kimi-k2-thinking (FREE)
+   qw/qwen3-coder-plus (FREE)
+   kr/claude-sonnet-4.5 (FREE)
+   gc/gemini-3-flash-preview (FREE 180K/month)
+   ```
+
+4. **Optimize prompts:**
+   - Reduce context size
+   - Use streaming for long responses
+   - Cache common prompts
+
+---
+
+## Connection Refused
+
+**Problem:** "ECONNREFUSED" or "Cannot connect to localhost:20128".
+
+**Causes:**
+- 9Router not running
+- Port 20128 blocked
+- Firewall blocking connection
+
+**Solutions:**
+
+1. **Start 9Router:**
+   ```bash
+   9router
+   ```
+   Dashboard should open at http://localhost:3000
+
+2. **Verify port 20128:**
+   ```bash
+   # Check if port is listening
+   lsof -i :20128
+   
+   # Or on Windows
+   netstat -ano | findstr :20128
+   ```
+
+3. **Check firewall:**
+   - macOS: System Settings → Network → Firewall
+   - Windows: Windows Defender Firewall → Allow app
+   - Linux: `sudo ufw allow 20128`
+
+4. **Use cloud endpoint:**
+   If localhost doesn't work (e.g., Cursor IDE):
+   ```
+   Endpoint: https://9router.com/v1
+   ```
+
+---
+
+## Dashboard Not Opening
+
+**Problem:** Dashboard doesn't load at http://localhost:3000.
+
+**Causes:**
+- Port 3000 already in use
+- 9Router crashed
+- Browser cache issues
+
+**Solutions:**
+
+1. **Check if 9Router is running:**
+   ```bash
+   # Check process
+   ps aux | grep 9router
+   
+   # Check port 3000
+   lsof -i :3000
+   ```
+
+2. **Kill conflicting process:**
+   ```bash
+   # macOS/Linux
+   lsof -ti:3000 | xargs kill -9
+   
+   # Windows
+   netstat -ano | findstr :3000
+   taskkill /PID <PID> /F
+   ```
+
+3. **Restart 9Router:**

+   - Try incognito mode
+
+5. **Check firewall settings:**
+   Ensure port 3000 is not blocked.
+
+---
+
+## Model Not Found
+
+**Problem:** "Model not found" or "Invalid model" errors.
+
+**Causes:**
+- Provider not connected
+- Model ID typo
+- Provider inactive
+
+**Solutions:**
+
+1. **Verify provider connection:**
+   ```
+   Dashboard → Providers → Check status (green = active)
+   ```
+
+2. **Check model ID format:**
+   ```
+   Correct: cc/claude-opus-4-5-20251101
+   Wrong: claude-opus-4-5-20251101
+   
+   Format: [provider-prefix]/[model-name]
+   ```
+
+3. **List available models:**
+   ```bash
+   curl http://localhost:20128/v1/models \
+     -H "Authorization: Bearer your-api-key"
+   ```
+
+4. **Reconnect provider:**
+   ```
+   Dashboard → Providers → [Provider] → Reconnect
+   ```
+
+---
+
+## Slow Response
+
+**Problem:** Requests take too long or timeout.
+
+**Causes:**
+- Provider latency
+- Network issues
+- Large context/response
+- Provider rate limiting
+
+**Solutions:**
+
+1. **Check provider status:**
+   ```
+   Dashboard → Providers → View latency stats
+   ```
+
+2. **Switch to faster model:**
+   ```
+   Fast: cc/claude-haiku-4-5 (Haiku is faster than Opus)
+         gc/gemini-3-flash-preview
+         qw/qwen3-coder-flash
+   ```
+
+3. **Use streaming:**
+   ```json
+   {
+     "model": "cc/claude-opus-4-5",
+     "messages": [...],
+     "stream": true
+   }
+   ```
+
+4. **Check network:**
+   ```bash
+   # Test latency
+   ping api.anthropic.com
+   ping api.openai.com
+   ```
+
+5. **Reduce context size:**
+   - Trim message history
+   - Use smaller prompts
+   - Enable context pruning in CLI tool
+
+---
+
+## API Key Invalid
+
+**Problem:** "Invalid API key" or "Authentication failed" errors.
+
+**Causes:**
+- Wrong API key copied
+- API key expired
+- API key not generated
+
+**Solutions:**
+
+1. **Regenerate API key:**
+   ```
+   Dashboard → Settings → API Keys → Generate New Key
+   → Copy and use new key
+   ```
+
+2. **Verify key format:**
+   ```
+   Correct: 9r_xxxxxxxxxxxxxxxxxxxxxxxx
+   Wrong: Missing 9r_ prefix
+   ```
+
+3. **Check key in CLI config:**
+   ```bash
+   # Cursor
+   Settings → Models → OpenAI API Key
+   
+   # Cline
+   Settings → API Key
+   
+   # Environment variable
+   export OPENAI_API_KEY="9r_your_key"
+   ```
+
+4. **Test API key:**
+   ```bash
+   curl http://localhost:20128/v1/models \
+     -H "Authorization: Bearer 9r_your_key"
+   ```

+
+# Monitorear recursos
+pm2 monit
+```
+
+---
+
+## 🐳 Despliegue con Docker
+
+### Opción 1: Usando Dockerfile
+
+Crea un `Dockerfile` en el directorio `app`:
+
+```dockerfile
+FROM node:20-alpine
+
+WORKDIR /app
+
+# Copy package files
+COPY package*.json ./
+
+# Install dependencies
+RUN npm ci --only=production

+
+## 🌐 Proxy reverso con Nginx
+
+### ¿Por qué usar Nginx?
+
+- Terminación SSL/TLS
+- Mapeo de nombre de dominio
+- Balanceo de carga
+- Mejor seguridad
+
+### Paso 1: Instalar Nginx
+
+```bash
+sudo apt update
+sudo apt install nginx
+```
+
+### Paso 2: Configurar Nginx
+
+Crea `/etc/nginx/sites-available/9router`:
+
+```nginx
+server {
+    listen 80;
+    server_name your-domain.com;
+
+    # Redirect HTTP to HTTPS
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name your-domain.com;
+
+    # SSL certificates (use certbot to generate)
+    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
+
+    # SSL configuration
+    ssl_protocols TLSv1.2 TLSv1.3;
+    ssl_ciphers HIGH:!aNULL:!MD5;
+    ssl_prefer_server_ciphers on;
+
+    # Proxy to 9Router
+    location / {
+        proxy_pass http://localhost:3000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_cache_bypass $http_upgrade;
+        
+        # SSE support - CRITICAL for streaming
+        proxy_buffering off;
+        proxy_read_timeout 86400;
+    }
+
+    # API endpoint
+    location /v1 {
+        proxy_pass http://localhost:20128;
+        proxy_http_version 1.1;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        
+        # SSE support - CRITICAL for streaming
+        proxy_buffering off;
+        proxy_read_timeout 86400;
+    }
+}
+```
+
+### Paso 3: Habilitar el sitio
+
+```bash
+# Crear enlace simbólico
+sudo ln -s /etc/nginx/sites-available/9router /etc/nginx/sites-enabled/
+
+# Probar configuración
+sudo nginx -t
+
+# Recargar Nginx
+sudo systemctl reload nginx
+```
+
+### Paso 4: Configurar SSL con Let's Encrypt
+
+```bash
+# Instalar certbot
+sudo apt install certbot python3-certbot-nginx
+
+# Obtener certificado SSL
+sudo certbot --nginx -d your-domain.com
+
+# La auto-renovación se configura automáticamente
+# Probar renovación
+sudo certbot renew --dry-run
+```
+
+---
+
+## 🔒 Consideraciones de seguridad
+
+### 1. Cambiar credenciales por defecto
+
+**CRÍTICO:** Cambia `JWT_SECRET` y `INITIAL_PASSWORD` antes del despliegue:
+
+```bash
+# Generar JWT secret seguro
+openssl rand -base64 32
+
+# Usa este valor para JWT_SECRET
+export JWT_SECRET="generated-secret-here"
+```
+
+### 2. Configuración del firewall
+
+```bash
+# Permitir SSH
+sudo ufw allow 22/tcp
+
+# Permitir HTTP/HTTPS (si usas Nginx)
+sudo ufw allow 80/tcp
+sudo ufw allow 443/tcp
+
+# Si NO usas proxy reverso, permite los puertos de 9Router
+sudo ufw allow 3000/tcp
+sudo ufw allow 20128/tcp
+
+# Habilitar firewall
+sudo ufw enable
+```
+
+### 3. Restringir el acceso al dashboard
+
+Si solo necesitas acceso por API, restringe el puerto del dashboard:
+
+```bash
+# Solo permitir acceso localhost al dashboard
+sudo ufw deny 3000/tcp
+```
+
+Accede al dashboard vía túnel SSH:
+
+```bash
+ssh -L 3000:localhost:3000 user@your-server.com
+# Luego abre http://localhost:3000 en tu navegador
+```
+
+### 4. Actualizaciones regulares
+
+```bash
+# Actualizar paquetes del sistema
+sudo apt update && sudo apt upgrade -y
+
+# Actualizar 9Router
+cd /path/to/9router/app
+git pull
+npm install
+npm run build
+pm2 restart 9router
+```
+
+### 5. Estrategia de respaldo
+
+```bash
+# Respaldar el directorio de datos
+tar -czf 9router-backup-$(date +%Y%m%d).tar.gz /var/lib/9router
+
+# Respaldo automatizado diario (agregar a crontab)
+0 2 * * * tar -czf /backups/9router-$(date +\%Y\%m\%d).tar.gz /var/lib/9router
+```
+
+---
+
+## 📊 Monitoreo
+
+### Verificar el estado de la aplicación
+
+```bash
+# Estado PM2
+pm2 status
+
+# Ver logs
+pm2 logs 9router --lines 100
+
+# Monitorear recursos
+pm2 monit
+```
+
+### Logs de Nginx
+
+```bash
+# Logs de acceso
+sudo tail -f /var/log/nginx/access.log
+
+# Logs de error
+sudo tail -f /var/log/nginx/error.log
+```
+
+### Recursos del sistema
+
+```bash
+# Uso de CPU y memoria
+htop
+
+# Uso de disco
+df -h
+
+# Conexiones de red
+netstat -tulpn | grep -E '3000|20128'
+```
+
+---
+
+## 🚨 Solución de problemas
+
+### La aplicación no inicia
+
+```bash
+# Verificar logs
+pm2 logs 9router
+
+# Verificar si los puertos están en uso
+sudo lsof -i :3000
+sudo lsof -i :20128
+
+# Verificar variables de entorno
+pm2 env 9router
+```
+
+### Nginx 502 Bad Gateway
+
+```bash
+# Verificar si 9Router está corriendo
+pm2 status
+
+# Verificar logs de error de Nginx
+sudo tail -f /var/log/nginx/error.log
+
+# Probar configuración de Nginx
+sudo nginx -t
+```
+
+### El streaming SSE no funciona
+
+Asegúrate de que `proxy_buffering off` esté configurado en Nginx para soporte SSE.
+
+### Errores de permiso denegado
+
+```bash
+# Corregir permisos del directorio de datos
+sudo chown -R $USER:$USER /var/lib/9router
+chmod 755 /var/lib/9router
+```

+
+---
+
+## ¿Puedo usar múltiples proveedores?
+
+**¡Sí! Esta es la característica principal de 9Router.**
+
+**Los combos te permiten encadenar múltiples proveedores con fallback automático:**
+
+```
+Ejemplo de combo: "premium-coding"
+1. cc/claude-opus-4-5 (Suscripción principal)
+2. glm/glm-4.7 (Respaldo barato)
+3. if/kimi-k2 (Emergencia gratis)
+
+→ Cambio automático cuando se agota la cuota
+→ Nunca para de codificar
+→ Costo extra mínimo
+```
+
+**Cómo crear combos:**
+```
+Dashboard → Combos → Create New
+→ Agrega modelos en orden de prioridad
+→ Usa el nombre del combo en CLI: "premium-coding"
+```
+
+**Beneficios:**
+- Cero tiempo de inactividad cuando se agota la cuota
+- Optimización automática de costos
+- Un solo nombre de modelo para todas las herramientas
+
+Consulta la [documentación de combos](features/combos.md) para ejemplos.
+
+---
+
+## ¿Cómo funciona el seguimiento de cuota?
+
+**9Router rastrea la cuota en tiempo real para todos los proveedores:**
+
+**Características:**
+- **Consumo de tokens** - Tokens de entrada/salida por solicitud
+- **Cuenta regresiva de reinicio** - Tiempo hasta que se refresca la cuota
+- **Estadísticas de uso** - Reportes diarios/semanales/mensuales
+- **Estimación de costos** - Gasto proyectado (niveles de pago)
+- **Alertas de cuota** - Notificaciones cuando la cuota es baja
+
+**Tipos de cuota:**
+- **5 horas rolling** - Claude Code, Codex, MiniMax
+- **Reinicio diario** - Gemini CLI (1K/día), GLM (10AM)
+- **Reinicio semanal** - Claude Code, Codex (cuota adicional)

+
+## ¿9Router funciona con Cursor?
+
+**Sí, pero Cursor requiere un endpoint en la nube.**
+
+**Problema:** Cursor IDE no soporta endpoints en localhost.
+
+**Solución:** Usa el despliegue en la nube de 9Router:
+
+```
+Cursor Settings → Models → Advanced:
+  OpenAI API Base URL: https://9router.com/v1
+  OpenAI API Key: [desde el dashboard]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+**Alternativa:** Auto-hospéda en VPS con dominio público:
+```bash
+# Despliega en VPS
+git clone https://github.com/decolua/9router.git
+cd 9router/app
+npm install && npm run build
+npm start
+
+# Configura proxy reverso Nginx
+# Apunta Cursor a: https://your-domain.com/v1
+```
+
+**Otras herramientas CLI funcionan con localhost:**
+- Cline ✅
+- Claude Desktop ✅
+- Codex CLI ✅
+- Continue ✅
+- RooCode ✅
+
+Consulta la [guía de integración de Cursor](integration/cursor.md) para detalles.
+
+---
+
+## ¿Puedo auto-hospedar 9Router?
+
+**¡Sí! 9Router soporta múltiples opciones de despliegue:**
+
+### Localhost (Por defecto)
+```bash
+npm install -g 9router
+9router
+→ Dashboard: http://localhost:3000
+→ API: http://localhost:20128/v1
+```
+
+### VPS/Cloud
+```bash
+git clone https://github.com/decolua/9router.git
+cd 9router/app
+npm install && npm run build
+
+export JWT_SECRET="your-secure-secret"
+export INITIAL_PASSWORD="your-password"
+export NODE_ENV="production"
+
+npm start
+```
+

+# Combos - Cadenas de fallback personalizadas
+
+Crea combinaciones de modelos personalizadas con fallback automático. Los combos te permiten definir tu propia estrategia de enrutamiento basada en costo, calidad y disponibilidad.
+
+---
+
+## ¿Qué son los combos?
+
+Los combos son **cadenas de fallback personalizadas** que creas en el dashboard. En lugar de usar un solo modelo, defines una secuencia de modelos que 9Router intenta en orden.
+
+**Ejemplo:**
+```
+Nombre del combo: premium-coding
+Modelos:
+  1. cc/claude-opus-4-5-20251101 (intentar primero)
+  2. glm/glm-4.7 (si #1 tiene cuota agotada)
+  3. minimax/MiniMax-M2.1 (si #2 tiene cuota agotada)
+```
+
+**Uso en CLI:**
+```
+Model: premium-coding
+```
+
+9Router intenta automáticamente cada modelo en secuencia hasta que uno tenga éxito.
+
+---
+
+## ¿Por qué usar combos?
+
+### 1. Maximiza el valor de la suscripción
+```
+cc/claude-opus → glm/glm-4.7 → if/kimi-k2-thinking
+
+→ Usa la suscripción primero, respaldo barato, emergencia gratis
+→ Obtén el valor completo de las suscripciones que ya pagas
+```
+
+### 2. Minimiza costos
+```
+glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+
+→ Comienza con la opción de pago más barata ($0.60/1M)
+→ Fallback a una aún más barata ($0.20/1M)
+→ Nivel de emergencia gratis
+→ Costo total: ~$5-10/mes vs $2000 en ChatGPT API
+```
+
+### 3. Garantiza disponibilidad 24/7
+```
+cc/claude-opus → cx/gpt-5.2-codex → glm/glm-4.7 → if/kimi-k2-thinking
+
+→ Siempre incluye el nivel gratis al final
+→ Nunca te quedes sin cuota
+→ Codifica en cualquier momento, en cualquier lugar
+```
+
+### 4. Optimiza por calidad
+```
+cc/claude-opus-4-5 → cx/gpt-5.2-codex → gc/gemini-3-pro
+
+→ Mejores modelos primero
+→ Fallback a otros modelos premium
+→ Mantén alta calidad en toda la cadena de fallback
+```
+
+---
+
+## Cómo crear combos
+
+### Paso 1: Abrir el dashboard
+
+```
+http://localhost:20128
+→ Inicia sesión con tu contraseña
+```
+
+### Paso 2: Navegar a Combos
+
+```
+Dashboard → Combos → Create New Combo
+```
+
+### Paso 3: Configurar el combo
+
+**Nombre del combo:**
+```
+premium-coding
+```
+
+**Descripción (opcional):**
+```
+Suscripción primero, respaldo barato, emergencia gratis
+```
+
+**Seleccionar modelos:**
+```
+1. cc/claude-opus-4-5-20251101
+2. glm/glm-4.7
+3. minimax/MiniMax-M2.1
+```
+
+**Arrastra para reordenar** - Prioridad de arriba a abajo.
+
+### Paso 4: Guardar
+
+```
+Clic en "Save Combo"
+→ El combo aparece en la lista de modelos
+```
+
+### Paso 5: Usar en CLI
+
+```
+Cursor/Cline/Cualquier herramienta:
+  Model: premium-coding
+```
+
+---
+
+## Combos de ejemplo
+
+### Ejemplo 1: Premium Coding (Suscripción → Barato → Gratis)
+
+**Objetivo**: Maximizar el valor de la suscripción, minimizar costos extras.
+
+```
+Dashboard → Combos → Create New
+
+Name: premium-coding
+Models:
+  1. cc/claude-opus-4-5-20251101
+  2. glm/glm-4.7
+  3. minimax/MiniMax-M2.1
+```
+
+**Uso:**
+```
+Cursor IDE:
+  Model: premium-coding
+```
+
+**Comportamiento:**
+```
+Mañana (cuota fresca):
+  Solicitud → cc/claude-opus-4-5 ✅
+
+Tarde (cuota de Claude agotada):
+  Solicitud → glm/glm-4.7 ✅ (cambio automático)
+
+Noche (cuota de GLM agotada):
+  Solicitud → minimax/MiniMax-M2.1 ✅ (cambio automático)
+```
+
+**Costo mensual (100M tokens):**
+```
+80M vía Claude Code: $0 (suscripción)
+15M vía GLM: $9
+5M vía MiniMax: $1
+Total: $10 + tu suscripción
+```
+
+**Ahorros**: ~99% vs ChatGPT API ($2000).
+
+---
+
+### Ejemplo 2: Combo de presupuesto (Barato → Gratis)
+
+**Objetivo**: Minimizar costos, usar el nivel gratis como respaldo.
+
+```
+Dashboard → Combos → Create New
+
+Name: budget-combo
+Models:
+  1. glm/glm-4.7
+  2. minimax/MiniMax-M2.1
+  3. if/kimi-k2-thinking
+```
+
+**Uso:**
+```
+Cline:
+  Provider: OpenAI Compatible
+  Base URL: http://localhost:20128/v1
+  Model: budget-combo
+```
+
+**Comportamiento:**
+```
+Solicitud → glm/glm-4.7
+  ✅ Cuota diaria disponible → Usa GLM ($0.60/1M)
+  ❌ Cuota agotada → Intenta MiniMax ($0.20/1M)
+  ❌ Cuota de MiniMax agotada → Usa iFlow (GRATIS)
+```
+
+**Costo mensual (100M tokens):**
+```
+70M vía GLM: $42
+20M vía MiniMax: $4
+10M vía iFlow: $0
+Total: $46 vs $2000 en ChatGPT API
+```
+
+**Ahorros**: 97%.
+
+---
+
+### Ejemplo 3: Combo gratis (Cero costo)
+
+**Objetivo**: 100% gratis, sin costos nunca.
+
+```
+Dashboard → Combos → Create New
+
+Name: free-combo
+Models:
+  1. if/kimi-k2-thinking
+  2. qw/qwen3-coder-plus
+  3. kr/claude-sonnet-4.5
+```
+
+**Uso:**
+```
+Claude Desktop:
+  Model: free-combo
+```
+
+**Comportamiento:**
+```
+Solicitud → if/kimi-k2-thinking
+  ✅ Disponible → Usa iFlow
+  ❌ Error → Intenta Qwen
+  ❌ Error → Intenta Kiro
+```
+
+**Costo mensual:**
+```
+100M tokens vía proveedores gratis: $0
+Total: $0 para siempre
+```
+
+**Caso de uso**: Proyectos personales, aprendizaje, experimentación.
+
+---
+
+### Ejemplo 4: Calidad primero (Solo modelos premium)
+
+**Objetivo**: Mejor calidad, sin fallback barato.
+
+```
+Dashboard → Combos → Create New
+
+Name: quality-first
+Models:
+  1. cc/claude-opus-4-5-20251101
+  2. cx/gpt-5.2-codex
+  3. gc/gemini-3-pro-preview
+```
+
+**Uso:**
+```
+Codex CLI:
+  export OPENAI_BASE_URL="http://localhost:20128"
+  Model: quality-first
+```
+
+**Comportamiento:**
+```
+Solicitud → cc/claude-opus-4-5
+  ❌ Cuota agotada → cx/gpt-5.2-codex
+  ❌ Cuota agotada → gc/gemini-3-pro-preview
+  ❌ Todo agotado → Devuelve error (sin fallback barato)
+```
+
+**Caso de uso**: Código crítico de producción, refactoring complejo.
+
+---
+
+### Ejemplo 5: Multi-suscripción (Maximiza todo)
+
+**Objetivo**: Usa todas las suscripciones antes de pagar extra.
+
+```
+Dashboard → Combos → Create New
+
+Name: multi-sub
+Models:
+  1. gc/gemini-3-flash-preview (GRATIS 180K/mes)
+  2. cc/claude-opus-4-5-20251101 (suscripción Pro)
+  3. cx/gpt-5.2-codex (suscripción Plus)
+  4. gh/gpt-5 (suscripción Copilot)
+  5. glm/glm-4.7 (respaldo barato)
+  6. if/kimi-k2-thinking (emergencia gratis)
+```
+
+**Costo mensual (200M tokens):**
+```
+50M vía Gemini CLI: $0 (nivel gratis)
+80M vía Claude Code: $0 (suscripción)
+40M vía Codex: $0 (suscripción)
+20M vía Copilot: $0 (suscripción)
+8M vía GLM: $4.80
+2M vía iFlow: $0
+Total: $4.80 + suscripciones existentes
+```
+
+**Resultado**: Usa 190M tokens de suscripciones, solo $4.80 extra.
+
+---
+
+### Ejemplo 6: Optimización de reinicio de cuota
+
+**Objetivo**: Distribuir el uso según los tiempos de reinicio.
+
+```
+Dashboard → Combos → Create New
+
+Name: reset-optimized
+Models:
+  1. cc/claude-opus-4-5 (reinicio 5h, usar mañana)
+  2. gc/gemini-3-flash (1K/día, usar tarde)
+  3. glm/glm-4.7 (reinicio diario 10AM, usar noche)
+  4. minimax/MiniMax-M2.1 (rolling 5h, usar madrugada)
+  5. if/kimi-k2-thinking (ilimitado, emergencia)
+```
+
+**Rutina diaria:**
+```
+08:00 - 13:00: Claude Code (cuota fresca de 5h)
+13:00 - 18:00: Gemini CLI (cuota 1K/día)
+18:00 - 22:00: GLM (se reinicia 10AM del día siguiente)
+22:00 - 08:00: MiniMax (rolling 5h) o iFlow
+```
+
+**Resultado**: Codifica 24/7 con costos mínimos.
+
+---
+
+## Usar combos en herramientas CLI
+
+### Cursor IDE
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [desde el dashboard]
+  Model: premium-coding
+```
+
+### Claude Desktop
+
+Edita `~/.claude/config.json`:
+```json
+{
+  "anthropic_api_base": "http://localhost:20128/v1",
+  "anthropic_api_key": "your-9router-api-key",
+  "model": "budget-combo"
+}
+```
+
+### Codex CLI
+
+```bash
+export OPENAI_BASE_URL="http://localhost:20128"
+export OPENAI_API_KEY="your-9router-api-key"
+
+codex --model quality-first "your prompt"
+```
+
+### Cline / Continue / RooCode
+
+```
+Provider: OpenAI Compatible
+Base URL: http://localhost:20128/v1
+API Key: [desde el dashboard]
+Model: free-combo
+```
+
+### Solicitud por API
+
+```bash
+curl http://localhost:20128/v1/chat/completions \
+  -H "Authorization: Bearer your-api-key" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "premium-coding",
+    "messages": [
+      {"role": "user", "content": "Write a function to..."}
+    ],
+    "stream": true
+  }'
+```
+
+---
+
+## Mejores prácticas
+
+### 1. Siempre incluye el nivel gratis
+
+```
+✅ Bueno:
+cc/claude-opus → glm/glm-4.7 → if/kimi-k2-thinking
+
+❌ Malo:
+cc/claude-opus → glm/glm-4.7
+(sin fallback gratis, puede quedarse sin cuota)
+```
+
+**Por qué**: Garantiza disponibilidad 24/7, nunca bloqueado por cuota.
+
+### 2. Ordena por costo (Barato a costoso)
+
+```
+✅ Bueno:
+glm/glm-4.7 → minimax/MiniMax-M2.1 → cc/claude-opus
+
+❌ Malo:
+cc/claude-opus → glm/glm-4.7
+(desperdicia cuota de suscripción en tareas simples)
+```
+
+**Excepción**: Si quieres maximizar el valor de la suscripción, pon la suscripción primero.
+
+### 3. Coincide con los requisitos de calidad
+
+```
+Para código de producción:
+cc/claude-opus → cx/gpt-5.2-codex → glm/glm-4.7
+
+Para tareas rápidas:
+glm/glm-4.7 → if/kimi-k2-thinking
+
+Para experimentación:
+if/kimi-k2-thinking → qw/qwen3-coder-plus
+```
+
+### 4. Considera los tiempos de reinicio de cuota
+
+```
+Combo matutino (cuotas frescas):
+cc/claude-opus → cx/gpt-5.2-codex
+
+Combo nocturno (cuotas probablemente agotadas):
+glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+```
+
+### 5. Crea múltiples combos para diferentes casos de uso
+
+```
+premium-coding: Para tareas complejas
+budget-combo: Para tareas simples
+free-combo: Para experimentación
+quality-first: Para código de producción
+```
+
+**Cambia entre combos** según los requisitos de la tarea.
+
+### 6. Monitorea el desempeño del combo
+
+```
+Dashboard → Analytics → Combo Usage:
+  premium-coding:
+    80% vía cc/claude-opus (bueno, usando suscripción)
+    15% vía glm/glm-4.7 (respaldo aceptable)
+    5% vía minimax (fallback raro)
+```
+
+**Optimiza**: Si hay demasiado uso de fallback, aumenta la cuota principal o reordena modelos.
+
+---
+
+## Configuración avanzada
+
+### Establecer límites de presupuesto por combo
+
+```
+Dashboard → Combos → Edit → Budget:
+  Daily limit: $5
+  Monthly limit: $50
+```
+
+Cuando se alcanza el límite, 9Router omite los modelos de pago y usa solo el nivel gratis.
+
+### Habilitar/Deshabilitar modelos en un combo
+
+```
+Dashboard → Combos → Edit → Models:
+  ✅ cc/claude-opus-4-5 (habilitado)
+  ❌ glm/glm-4.7 (deshabilitado temporalmente)
+  ✅ if/kimi-k2-thinking (habilitado)
+```
+
+**Caso de uso**: Deshabilitar temporalmente modelos costosos sin eliminar el combo.
+
+### Clonar un combo existente
+
+```
+Dashboard → Combos → Clone "premium-coding"
+→ Crea una copia con sufijo "-copy"
+→ Modifica y guarda como nuevo combo
+```
+
+**Caso de uso**: Crear variaciones para diferentes escenarios.
+
+---
+
+## Solución de problemas
+
+**Problema: El combo no aparece en la lista de modelos**
+
+**Solución:**
+1. Refresca el dashboard
+2. Verifica que el combo esté guardado (marca verde)
+3. Reinicia la herramienta CLI para refrescar la lista de modelos
+
+**Problema: El combo siempre usa el último modelo (nivel gratis)**
+
+**Solución:**
+1. Verifica la cuota de los modelos principales (Dashboard → Quota)
+2. Verifica que las API keys sean válidas (Dashboard → Providers)
+3. Verifica que no se hayan excedido los límites de presupuesto
+
+**Problema: El combo cuesta más de lo esperado**
+
+**Solución:**
+1. Dashboard → Analytics → Revisa el uso del combo
+2. Verifica si los modelos principales tienen cuota agotada
+3. Reordena los modelos (pon los más baratos primero)
+4. Establece límites de presupuesto
+

+   Proyectado: $135 (dentro del presupuesto)
+   
+🚨 Presupuesto diario excedido
+   $5.20 / $5.00 gastados hoy
+   Cambio automático al nivel gratis
+```
+
+### Detección de anomalías de costo
+
+```
+Dashboard → Settings → Anomaly Detection
+
+✅ Detectar patrones de gasto inusuales
+✅ Alerta en picos de costo (>2× promedio diario)
+✅ Advertencia en patrones de agotamiento de cuota
+
+Ejemplo de alerta:
+⚠️ Pico de costo detectado
+   Hoy: $12.50 (2.5× promedio diario)
+   Razón: Alto uso de GLM-4.7 (20M tokens)
+   Sugerencia: Verifica si los modelos principales tienen cuota agotada
+```
+
+---
+
+## Mejores prácticas
+
+### 1. Monitorea la cuota diariamente
+
+```
+Rutina diaria:
+1. Revisa el resumen de cuota del dashboard (30 segundos)
+2. Revisa los tiempos de reinicio
+3. Planifica el uso según la disponibilidad de cuota
+```
+
+**Ejemplo:**
+```
+Revisión matutina:
+  ✅ Claude Code: 5h disponibles (reinicio fresco)
+  ✅ Gemini CLI: 1K solicitudes disponibles
+  ⚠️ GLM-4.7: 2M tokens restantes (se reinicia 10AM)
+  
+Acción: Usar Claude Code para el trabajo matutino
+```
+
+### 2. Establece límites de presupuesto
+
+```
+Dashboard → Settings → Budget:
+  Diario: $5 (previene gastos excesivos)
+  Mensual: $150 (alinea con el presupuesto)
+```
+
+**Resultado**: Cambio automático al nivel gratis cuando se alcanza el límite.
+
+### 3. Optimiza el uso de combos
+
+```
+Dashboard → Analytics → Combos:
+  Revisa qué modelos se usan más
+  Ajusta el orden del combo para minimizar costos
+```
+
+**Ejemplo:**
+```
+Actual: cc/claude-opus → glm/glm-4.7
+  80% vía Claude (bueno)
+  20% vía GLM ($12/mes)
+
+Optimizado: gc/gemini-3-flash → cc/claude-opus → glm/glm-4.7
+  50% vía Gemini (gratis)
+  40% vía Claude (suscripción)
+  10% vía GLM ($6/mes)
+  
+Ahorros: $6/mes
+```
+
+### 4. Rastrea los tiempos de reinicio
+
+```
+Dashboard → Quota → Reset Schedule:
+  Claude Code: 5h rolling + Semanal lunes
+  Gemini CLI: Diario 00:00 UTC + Mensual día 1
+  GLM-4.7: Diario 10:00 AM hora Beijing
+  MiniMax: Ventana rolling 5h
+```
+
+**Estrategia**: Usa proveedores cuando la cuota esté fresca.
+
+### 5. Revisa los reportes mensuales
+
+```
+Dashboard → Analytics → Monthly Report:
+  Total de tokens: 1.5B
+  Costo total: $120
+  Ahorros: 97% vs ChatGPT API
+  
+Insights:
+  - 60% de uso vía suscripciones ($0)
+  - 30% vía GLM ($90)
+  - 10% vía nivel gratis ($0)
+  
+Optimización:
+  - Aumentar el uso de Gemini CLI (gratis)
+  - Reducir el uso de GLM (costoso)
+```

+
+## Solución de problemas
+
+**Problema: La cuota muestra 0% pero las solicitudes fallan**
+
+**Solución:**
+1. Verifica la conexión del proveedor (Dashboard → Providers)
+2. Verifica que las API keys sean válidas
+3. Verifica si el proveedor está caído (página de estado)
+4. Intenta reconectar los proveedores OAuth
+
+**Problema: Estimación de costos incorrecta**
+
+**Solución:**
+1. Dashboard → Settings → Pricing
+2. Verifica que el precio por proveedor coincida con las tarifas actuales
+3. Actualiza el precio si el proveedor cambió las tarifas
+4. Contacta a soporte si la discrepancia persiste
+
+**Problema: El tiempo de reinicio no se actualiza**
+
+**Solución:**
+1. Refresca el dashboard (F5)
+2. Verifica que la hora del sistema sea correcta
+3. Verifica la configuración de zona horaria
+4. Reinicia 9Router si el problema persiste
+
+**Problema: No se reciben alertas**
+
+**Solución:**
+1. Dashboard → Settings → Alerts
+2. Verifica que la dirección de email sea correcta
+3. Revisa la carpeta de spam
+4. Prueba la notificación (botón Send Test)

+# Enrutamiento inteligente y fallback automático
+
+9Router enruta automáticamente tus solicitudes a través del mejor proveedor disponible usando un sistema de fallback de 3 niveles. Nunca dejes de codificar debido a límites de cuota o rate-limiting.
+
+---
+
+## Cómo funciona
+
+9Router usa enrutamiento inteligente para maximizar tus suscripciones existentes, minimizar costos y garantizar disponibilidad 24/7:
+
+```
+Solicitud → 9Router → Verificar Nivel 1 (Suscripción)
+                       ↓ cuota agotada
+                       Verificar Nivel 2 (Barato)
+                       ↓ límite de presupuesto
+                       Verificar Nivel 3 (Gratis)
+                       ↓
+                       Respuesta
+```
+
+### Sistema de fallback de 3 niveles
+
+**Nivel 1: SUSCRIPCIÓN (Primario)**
+- Claude Code (Pro/Max)
+- OpenAI Codex (Plus/Pro)
+- Gemini CLI (GRATIS 180K/mes)
+- GitHub Copilot
+- Antigravity (Google)
+
+**Objetivo**: Maximizar el valor de las suscripciones que ya pagas.
+
+**Nivel 2: BARATO (Respaldo)**
+- GLM-4.7 ($0.60/1M entrada)
+- MiniMax M2.1 ($0.20/1M entrada)
+- Kimi K2 ($9/mes plano)
+
+**Objetivo**: Respaldo ultra-barato cuando se agota la cuota de suscripción (~90% más barato que ChatGPT API).
+
+**Nivel 3: GRATIS (Emergencia)**
+- iFlow (8 modelos)
+- Qwen (3 modelos)
+- Kiro (Claude GRATIS)
+
+**Objetivo**: Fallback de cero costo para codificación ilimitada.
+
+---
+
+## Cambio automático
+
+9Router monitorea la cuota en tiempo real y cambia de proveedor automáticamente:
+
+### Escenario 1: Cuota de suscripción agotada
+
+```

+
+**Resultado**: Cero tiempo de inactividad, experiencia sin interrupciones.
+
+### Escenario 2: Rate limiting
+
+```
+Solicitud del usuario → cx/gpt-5.2-codex
+                       ↓ rate limited (demasiadas solicitudes)
+                       Cambio automático → glm/glm-4.7

+                       Respuesta entregada ✅
+```
+
+### Escenario 3: Proveedor no disponible
+
+```
+Solicitud del usuario → cc/claude-opus-4-5
+                       ↓ error del proveedor (503)
+                       Cambio automático → siguiente modelo disponible
+                       ↓
+                       Respuesta entregada ✅
+```
+
+---
+
+## Lógica de selección de modelo
+
+9Router selecciona el mejor modelo según:
+
+1. **Disponibilidad de cuota** - Verifica si el proveedor tiene cuota restante
+2. **Nivel de costo** - Prefiere suscripción → barato → gratis
+3. **Tiempo de reinicio** - Considera cuándo se reinicia la cuota
+4. **Salud del proveedor** - Omite proveedores con errores
+
+### Ejemplo de orden de prioridad
+
+Para una solicitud a `cc/claude-opus-4-5`:
+
+```
+1. Verificar cuota de Claude Code
+   ✅ Disponible → Usa cc/claude-opus-4-5
+   ❌ Agotada → Continúa al paso 2
+
+2. Verificar nivel de fallback (si está configurado)
+   ✅ Cuota de GLM disponible → Usa glm/glm-4.7
+   ❌ Agotada → Continúa al paso 3
+
+3. Verificar nivel gratis
+   ✅ iFlow disponible → Usa if/kimi-k2-thinking
+   ❌ Todo agotado → Devuelve error de cuota
+```
+
+---
+
+## Opciones de configuración
+
+### Configuración del dashboard
+
+**1. Habilitar/Deshabilitar fallback automático**
+
+```
+Dashboard → Settings → Smart Routing
+→ Toggle "Auto Fallback" ON/OFF
+```
+
+- **ON** (por defecto): Cambio automático de nivel
+- **OFF**: Modo estricto, devuelve error si el modelo principal no está disponible
+
+**2. Establecer límites de presupuesto**
+
+```
+Dashboard → Settings → Budget Control
+→ Límite diario: $5
+→ Límite mensual: $50
+```
+
+Cuando se alcanza el presupuesto, 9Router cambia automáticamente al nivel gratis.
+
+**3. Configurar el orden de fallback**
+
+```
+Dashboard → Settings → Fallback Priority
+→ Arrastra para reordenar proveedores dentro de cada nivel
+```
+
+Ejemplo de orden personalizado:
+```
+Nivel 1: Gemini CLI → Claude Code → Codex
+Nivel 2: MiniMax → GLM → Kimi
+Nivel 3: iFlow → Kiro → Qwen
+```
+
+**4. Notificaciones de reinicio de cuota**
+
+```
+Dashboard → Settings → Notifications
+→ Email cuando se reinicia la cuota
+→ Alerta cuando se usa 80% de cuota
+```
+
+---
+
+## Ejemplos
+
+### Ejemplo 1: Fallback automático básico
+
+**Configuración:**
+```
+Model: cc/claude-opus-4-5-20251101
+Fallback: Auto (3 niveles por defecto)
+```
+
+**Comportamiento:**
+```
+Mañana (cuota fresca):
+  Solicitud → cc/claude-opus-4-5 ✅
+
+Tarde (cuota agotada):
+  Solicitud → glm/glm-4.7 ✅ (cambio automático)
+
+Noche (cuota de GLM agotada):
+  Solicitud → minimax/MiniMax-M2.1 ✅ (cambio automático)
+
+Madrugada (toda la cuota de pago agotada):
+  Solicitud → if/kimi-k2-thinking ✅ (nivel gratis)
+```
+
+**Costo**: ~$5-10/mes extra (en su mayoría cubierto por la suscripción).
+
+### Ejemplo 2: Enrutamiento consciente del presupuesto
+
+**Configuración:**
+```
+Dashboard → Settings:
+  Presupuesto diario: $2
+  Presupuesto mensual: $20
+  Fallback: Habilitado
+```
+
+**Comportamiento:**
+```
+Día 1-15 (dentro del presupuesto):
+  Solicitudes → glm/glm-4.7 (nivel barato)
+  Costo: $1.50/día
+
+Día 16 (presupuesto alcanzado):
+  Solicitudes → if/kimi-k2-thinking (nivel gratis)
+  Costo: $0
+
+Mes siguiente (presupuesto se reinicia):
+  Solicitudes → glm/glm-4.7 nuevamente
+```
+
+**Resultado**: Nunca excede $20/mes, siempre disponible.
+
+### Ejemplo 3: Modo solo suscripción
+
+**Configuración:**
+```
+Dashboard → Settings:
+  Fallback automático: OFF
+  Modo estricto: ON
+```
+
+**Comportamiento:**
+```
+Solicitud → cc/claude-opus-4-5
+  ✅ Cuota disponible → Éxito
+  ❌ Cuota agotada → Devuelve error (sin fallback)
+```
+
+**Caso de uso**: Cuando solo quieres usar suscripciones de pago, sin costos extras.
+
+### Ejemplo 4: Modo solo gratis
+
+**Configuración:**
+```
+Model: if/kimi-k2-thinking
+Fallback: qw/qwen3-coder-plus → kr/claude-sonnet-4.5
+```
+
+**Comportamiento:**
+```
+Todas las solicitudes → Solo nivel gratis
+Costo: $0 para siempre
+```
+
+**Caso de uso**: Proyectos personales, aprendizaje, experimentación.
+
+---
+
+## Mejores prácticas
+
+### 1. Maximiza el valor de la suscripción
+
+```
+Estrategia:
+- Establece modelos de suscripción como Nivel 1
+- Monitorea el uso de cuota en el dashboard
+- Usa el nivel barato solo cuando la suscripción se agote
+```
+
+**Ejemplo de combo:**
+```
+cc/claude-opus-4-5 → glm/glm-4.7 → if/kimi-k2-thinking
+```
+
+### 2. Optimiza por costo
+
+```
+Estrategia:
+- Usa el nivel gratis de Gemini CLI primero (180K/mes)
+- Fallback a GLM/MiniMax (ultra-baratos)
+- Emergencia: iFlow (gratis)
+```
+
+**Ejemplo de combo:**
+```
+gc/gemini-3-flash-preview → glm/glm-4.7 → if/kimi-k2-thinking
+```
+
+### 3. Optimiza por calidad
+
+```
+Estrategia:
+- Usa los mejores modelos (Claude Opus, GPT-5.2)
+- Fallback a modelos baratos buenos (GLM-4.7)
+- Último recurso: Nivel gratis
+```
+
+**Ejemplo de combo:**
+```
+cc/claude-opus-4-5 → cx/gpt-5.2-codex → glm/glm-4.7
+```
+
+### 4. Disponibilidad 24/7
+
+```
+Estrategia:
+- Siempre incluye el nivel gratis en el fallback
+- Monitorea los tiempos de reinicio de cuota
+- Distribuye el uso entre proveedores
+```
+
+**Ejemplo de combo:**
+```
+cc/claude-opus-4-5 → glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+```
+
+**Resultado**: Nunca te quedas sin cuota, codifica en cualquier momento.
+
+---
+
+## Estrategia de reinicio de cuota
+
+Planifica tu uso según los tiempos de reinicio de cuota:
+
+| Proveedor | Reinicio de cuota | Estrategia |
+|----------|-------------|----------|
+| **Claude Code** | 5 horas + semanal | Usar en la mañana, cuota fresca |
+| **Codex** | 5 horas + semanal | Usar después de cuota de Claude |
+| **Gemini CLI** | Diario (1K) + Mensual (180K) | Usar durante el día |
+| **GLM-4.7** | Diario 10:00 AM | Usar en la noche, se reinicia al día siguiente |
+| **MiniMax M2.1** | Rolling 5 horas | Usar cuando sea, rastrea ventana rolling |
+| **iFlow/Qwen/Kiro** | Sin límite | Respaldo de emergencia |
+
+**Ejemplo de rutina diaria:**
+```
+08:00 - 13:00: Claude Code (cuota fresca 5h)
+13:00 - 18:00: Gemini CLI (cuota 1K/día)
+18:00 - 22:00: GLM-4.7 (barato, se reinicia 10AM)
+22:00 - 08:00: MiniMax o iFlow (rolling 5h o gratis)
+```
+
+---
+
+## Monitoreo y alertas
+
+### Rastreador de cuota del dashboard
+
+```
+Dashboard → Quota Overview:
+  Claude Code: 2.5h / 5h restantes (50%)
+  Gemini CLI: 450 / 1000 solicitudes hoy
+  GLM-4.7: 5M / 10M tokens (se reinicia en 8h)
+  MiniMax: 3M / 5M tokens (rolling 5h)
+```
+
+### Notificaciones en tiempo real
+
+```
+Dashboard → Notifications:
+  ⚠️ Cuota de Claude Code 80% usada (1h restante)
+  ✅ Cuota de GLM-4.7 reiniciada (10M tokens disponibles)
+  💰 Presupuesto diario 50% usado ($2.50 / $5)
+```
+
+### Analítica de uso
+
+```
+Dashboard → Analytics:
+  Hoy: 50M tokens
+    - 30M vía Claude Code (suscripción)
+    - 15M vía GLM-4.7 ($9)
+    - 5M vía iFlow (gratis)
+  
+  Costo: $9 (vs $1000 en ChatGPT API)
+  Ahorros: 99%
+```
+
+---
+
+## Solución de problemas
+
+**Problema: "All providers quota exhausted"**
+
+**Solución:**
+1. Verifica el rastreador de cuota del dashboard
+2. Espera el reinicio de cuota (mira la cuenta regresiva)
+3. Agrega el nivel gratis a la cadena de fallback
+4. O aumenta el límite de presupuesto
+
+**Problema: "Demasiados cambios de fallback"**
+
+**Solución:**
+1. Verifica si el proveedor principal está caído
+2. Aumenta los límites de cuota (mejora la suscripción)
+3. Usa un modelo principal más barato (GLM en lugar de Claude)
+
+**Problema: "Costos inesperados"**
+
+**Solución:**
+1. Dashboard → Analytics → Revisa el uso
+2. Establece límites de presupuesto diarios/mensuales
+3. Cambia al nivel gratis para tareas no críticas
+4. Usa combos con fallback gratis

+3. Dashboard → Add API Key → Provider: `glm` → Pega la key
+4. ✅ ¡Listo! Usa el modelo: `glm/glm-4.7`
+
+#### Opción C: Proveedores gratis (Sin costo)
+
+**Ideal para:** iFlow, Qwen, Kiro
+
+```
+Dashboard → Providers → Connect [Free Provider]
+→ Device code u OAuth
+→ Uso ilimitado
+```
+
+**Ejemplo: iFlow**
+1. Clic en "Connect iFlow"
+2. Inicia sesión con tu cuenta de iFlow
+3. Autoriza
+4. ✅ ¡Listo! Usa 8 modelos: `if/kimi-k2-thinking`, `if/qwen3-coder-plus`, etc.
+
+---
+
+## 4. Usar en herramientas CLI
+
+Apunta tu herramienta de codificación a 9Router:
+
+### Cursor IDE
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [desde el dashboard de 9router]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+### Claude Desktop
+
+Edita `~/.claude/config.json`:
+
+```json
+{
+  "anthropic_api_base": "http://localhost:20128/v1",
+  "anthropic_api_key": "your-9router-api-key"
+}
+```
+
+### Cline / Continue / RooCode
+
+```
+Provider: OpenAI Compatible
+Base URL: http://localhost:20128/v1
+API Key: [desde el dashboard]
+Model: cc/claude-opus-4-5-20251101
+```
+
+### Codex CLI
+
+```bash
+export OPENAI_BASE_URL="http://localhost:20128"
+export OPENAI_API_KEY="your-9router-api-key"
+
+codex "your prompt"
+```
+
+---
+
+## 5. Crear combos inteligentes (Opcional)
+
+Los combos habilitan el fallback automático entre modelos:
+
+```
+Dashboard → Combos → Create New
+
+Name: premium-coding
+Models:
+  1. cc/claude-opus-4-5-20251101 (Suscripción principal)
+  2. glm/glm-4.7 (Respaldo barato, $0.6/1M)
+  3. if/kimi-k2-thinking (Fallback gratis)
+
+Usar en CLI: premium-coding
+```
+
+**Cómo funciona:**
+1. Intenta primero Claude Opus (tu suscripción)
+2. Si la cuota se agota → GLM-4.7 (ultra-barato)
+3. Si llega al límite de presupuesto → iFlow (gratis)
+4. ¡Cero tiempo de inactividad, cambio automático!
+
+---

+  60M vía Gemini CLI: $0 (nivel gratis)
+  30M vía Claude Code: $0 (suscripción que ya tienes)
+  8M vía GLM: $4.80
+  2M vía MiniMax: $0.40
+  Total: $5.20/mes + suscripciones existentes
+```
+
+### Estrategia de reinicio de cuota
+
+```
+Rutina diaria:
+1. Mañana: Cuota fresca de Claude Code (reinicio 5h)
+2. Tarde: Cambia a Gemini CLI (1K/día)
+3. Noche: Cuota diaria de GLM (reinicio 10AM del día siguiente)
+4. Madrugada: MiniMax (rolling 5h) o iFlow (gratis)
+
+→ ¡Codifica 24/7 con costo extra mínimo!

+## Patrones comunes de integración
+
+### Variables de entorno
+
+Almacena credenciales de forma segura:
+
+```bash
+# .env file
+ROUTER_API_KEY=your-api-key-from-dashboard
+ROUTER_BASE_URL=http://localhost:20128/v1
+ROUTER_MODEL=cc/claude-sonnet-4-20250514
+```
+
+```python
+import os
+from openai import OpenAI
+
+client = OpenAI(
+    api_key=os.getenv("ROUTER_API_KEY"),
+    base_url=os.getenv("ROUTER_BASE_URL")
+)
+```
+
+### Manejo de errores
+
+```python
+from openai import OpenAI, OpenAIError
+
+client = OpenAI(
+    api_key="your-api-key",
+    base_url="http://localhost:20128/v1"
+)
+
+try:
+    response = client.chat.completions.create(
+        model="cc/claude-sonnet-4-20250514",
+        messages=[{"role": "user", "content": "Hello"}]
+    )
+    print(response.choices[0].message.content)
+except OpenAIError as e:
+    print(f"Error: {e}")
+```
+
+### Lógica de reintentos
+
+```python
+import time
+from openai import OpenAI, RateLimitError
+
+client = OpenAI(
+    api_key="your-api-key",
+    base_url="http://localhost:20128/v1"
+)
+
+def chat_with_retry(prompt, max_retries=3):

+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [desde el dashboard de 9router]
+  Model: glm/glm-4.7
+```
+
+### Crear combo (Recomendado)
+
+```
+Dashboard → Combos → Create New
+
+Name: cheap-backup
+Models:
+  1. cc/claude-opus-4-5 (Suscripción principal)
+  2. glm/glm-4.7 (Respaldo barato, reinicio diario)
+  3. minimax/MiniMax-M2.1 (Fallback más barato)
+  4. if/kimi-k2-thinking (Emergencia GRATIS)
+
+Usar en CLI: cheap-backup
+```
+
+**Resultado:** Suscripción → Barato → Más barato → Gratis
+
+---
+
+## Optimización de costos
+
+### Estrategia 1: Rutina de reinicio diario
+
+```
+Mañana (10AM): Cuota fresca de GLM
+→ Usa GLM para tareas pesadas
+→ Ahorra cuota de suscripción
+
+Tarde: Cuota de suscripción
+→ Usa Claude/Codex para tareas complejas
+
+Noche: MiniMax (reinicio 5h)
+→ Respaldo barato para trabajo nocturno
+
+Madrugada: Nivel gratis (iFlow)
+→ Respaldo de emergencia cero costo
+```
+
+### Estrategia 2: Presupuesto primero
+
+```
+Establece presupuesto mensual: $20
+
+Asignación:
+- $9 Kimi K2 (10M tokens plano)
+- $6 cuota diaria de GLM (10M tokens)
+- $5 overflow de MiniMax (25M tokens)
+
+Total: 45M tokens por $20
+¡vs 1M tokens por $20 en ChatGPT API!
+```
+
+### Estrategia 3: Maximiza suscripciones primero
+
+```
+Prioridad:
+1. Gemini CLI (180K/mes GRATIS)
+2. Claude Code (suscripción que ya pagas)
+3. GLM-4.7 (respaldo barato, $0.6/1M)
+4. MiniMax M2.1 (más barato, $0.2/1M)
+5. iFlow (emergencia GRATIS)
+
+Ejemplo de costo mensual (100M tokens):
+- 60M vía Gemini CLI: $0 (gratis)
+- 30M vía Claude Code: $0 (suscripción)
+- 8M vía GLM: $4.80
+- 2M vía MiniMax: $0.40
+¡Total: $5.20/mes!
+```
+
+---
+
+## Ejemplos reales
+
+### Ejemplo 1: Mes de codificación intensa (100M tokens)
+
+```
+Desglose:
+- 60M vía suscripción (Claude/Codex): $0 extra
+- 30M vía GLM-4.7: $18
+- 10M vía MiniMax M2.1: $2
+
+Total: $20/mes
+¡vs $2000 en ChatGPT API!
+
+Ahorros: ¡99% más barato!
+```
+
+### Ejemplo 2: Codificador con presupuesto ($10/mes)
+
+```
+Estrategia:
+- $9 Kimi K2 (10M tokens)
+- $1 overflow de MiniMax (5M tokens)
+
+Total: 15M tokens por $10
+¡vs 0.5M tokens por $10 en ChatGPT API!
+
+¡30× más tokens!
+```
+
+### Ejemplo 3: Freelancer (Uso variable)
+
+```
+Mes ligero (20M tokens):
+- 15M vía suscripción: $0
+- 5M vía GLM: $3
+Total: $3
+
+Mes intenso (150M tokens):
+- 60M vía suscripción: $0
+- 60M vía GLM: $36
+- 30M vía MiniMax: $6
+Total: $42
+
+Promedio: $22.50/mes
+¡vs $3400 en ChatGPT API!
+```
+
+---
+
+## Mejores prácticas
+
+### 1. Rastrea la cuota diaria
+
+```
+El dashboard muestra:
+- Cuota GLM: 75% usado (reinicio en 6h)
+- Cuota MiniMax: 50% usado (reinicio en 2h)
+- Cuota Kimi: 8M/10M usado (reinicio en 15 días)
+
+¡Planifica tareas pesadas según los tiempos de reinicio!
+```
+
+### 2. Usa el Coding Plan (GLM)
+
+```
+Standard: 1× cuota
+Coding Plan: 3× cuota (¡mismo precio!)
+
+→ Siempre elige Coding Plan
+```
+
+### 3. Combina con el nivel gratis
+
+```
+Combo:
+1. gc/gemini-3-flash (GRATIS principal)
+2. glm/glm-4.7 (respaldo barato)
+3. minimax/MiniMax-M2.1 (más barato)
+4. if/kimi-k2-thinking (emergencia GRATIS)
+
+Resultado: Minimiza costos, maximiza uptime
+```
+
+### 4. Establece alertas de presupuesto
+
+```
+Dashboard → Settings → Budget Alerts
+
+Diario: $2 límite
+Semanal: $10 límite
+Mensual: $30 límite
+
+→ Cambio automático al nivel gratis cuando se alcanza el límite
+```
+
+---
+
+## Solución de problemas
+
+### "Cuota agotada"
+
+**Solución:**
+- GLM: Espera hasta las 10:00 AM hora Beijing
+- MiniMax: Espera 5 horas desde el primer uso
+- Kimi: Espera hasta el 1ro del próximo mes
+- Usa fallback de combo al nivel gratis
+
+### "API key inválida"
+
+**Solución:**
+- Verifica que la API key esté copiada correctamente
+- Verifica que la cuenta tenga créditos
+- Regenera la API key si es necesario
+
+### "Costos altos"
+
+**Solución:**
+- Revisa las estadísticas de uso en el dashboard
+- Establece alertas de presupuesto
+- Cambia a MiniMax ($0.2/1M, la más barata)
+- Usa el nivel gratis para tareas no críticas
+
+---
+
+## Próximos pasos
+
+- **Agregar fallback gratis:** [Proveedores gratis](./free.md)
+- **Configurar suscripciones:** [Proveedores de suscripción](./subscription.md)

+
+## Solución de problemas
+
+### "OAuth failed"
+
+**Solución:**
+- Verifica la conexión a internet
+- Prueba otro navegador
+- Limpia la caché del navegador
+- Reconecta en el dashboard
+
+### "Modelo no disponible"
+
+**Solución:**
+- Verifica que el proveedor esté conectado en el dashboard
+- Verifica que el token OAuth sea válido
+- Reconecta el proveedor si es necesario
+
+### "Respuestas lentas"
+
+**Solución:**
+- El nivel gratis puede tener menor prioridad
+- Úsalo durante horas off-peak
+- Cambia a otro proveedor gratis
+- Mejora al nivel barato para velocidad
+
+---
+
+## Limitaciones
+
+### Consideraciones del nivel gratis
+
+- **Velocidad** - Puede ser más lento que los niveles de pago
+- **Prioridad** - Menor prioridad en horas pico
+- **Rate limits** - Posible rate-limiting (pero cuota ilimitada)
+- **Disponibilidad** - Puede tener tiempo de inactividad ocasional
+
+**Solución:** ¡Usa la estrategia de fallback de 3 niveles para confiabilidad!
+
+---
+
+## Próximos pasos
+
+- **Configurar suscripciones:** [Proveedores de suscripción](./subscription.md)
+- **Agregar respaldo barato:** [Proveedores baratos](./cheap.md)
+- **Crear combos:** Dashboard → Combos → Create New
+- **Empezar a codificar:** Usa el combo `complete-fallback` para máxima confiabilidad

+  OpenAI API Key: [desde el dashboard de 9router]
+  Model: cc/claude-opus-4-5-20251101

+
+```
+Dashboard → Combos → Create New

+Name: premium-coding
+Models:
+  1. gc/gemini-3-flash-preview (GRATIS, usar primero)
+  2. cc/claude-opus-4-5-20251101 (Suscripción)
+  3. cx/gpt-5.2-codex (Respaldo de suscripción)
+
+Usar en CLI: premium-coding
+```
+
+**Resultado:** Maximiza el nivel gratis → Usa suscripción → Fallback automático
+
+---
+
+## Seguimiento de cuota
+
+9Router rastrea la cuota en tiempo real:
+
+- **Consumo de tokens** - Tokens de entrada/salida por solicitud
+- **Cuenta regresiva de reinicio** - Tiempo hasta el próximo reinicio de cuota
+- **Porcentaje de uso** - Cuánta cuota se ha usado
+- **Fallback automático** - Cambia al siguiente nivel cuando se agota
+
+**Vista del dashboard:**
+
+```
+Claude Code Pro
+├─ Cuota: 75% usada
+├─ Reinicio: 2h 15m (5 horas)
+├─ Reinicio semanal: 3 días
+└─ Fallback: glm/glm-4.7 (nivel barato)
+```
+
+---
+
+## Mejores prácticas
+
+### 1. Usa el nivel gratis primero
+
+```
+Prioridad:
+1. Gemini CLI (180K/mes GRATIS)
+2. Antigravity (Claude GRATIS)
+3. Claude Code/Codex (suscripciones de pago)
+```
+
+### 2. Rastrea la cuota diariamente
+
+- Revisa el dashboard cada mañana
+- Planifica tareas pesadas según reinicios de cuota
+- Usa el nivel barato/gratis para tareas no críticas
+
+### 3. Crea combos inteligentes
+
+```
+Ejemplo de combo:
+1. gc/gemini-3-flash-preview (GRATIS principal)
+2. cc/claude-opus-4-5 (Tareas complejas)
+3. glm/glm-4.7 (Respaldo barato)
+4. if/kimi-k2-thinking (Fallback GRATIS)
+```
+
+### 4. Optimiza por tiempo
+
+```
+Mañana: Cuota fresca de 5 horas (Claude/Codex)
+Tarde: Gemini CLI (1K/día)
+Noche: Cuota de suscripción
+Madrugada: Nivel barato/gratis
+```
+
+---
+
+## Solución de problemas
+
+### "Cuota agotada"
+
+**Solución:**
+- Verifica el rastreador de cuota del dashboard
+- Espera el reinicio (5 horas o diario)
+- Usa fallback de combo al nivel barato/gratis
+
+### "Token OAuth expirado"
+
+**Solución:**
+- Auto-refresh por 9Router
+- Si hay problemas: Dashboard → Provider → Reconnect
+
+### "Rate limiting"
+

+# Solución de problemas
+
+Problemas comunes y soluciones al usar 9Router.
+
+---
+
+## "Language model did not provide messages"
+
+**Problema:** La solicitud falla con una respuesta vacía o un mensaje de error.
+
+**Causas:**
+- Cuota del proveedor agotada
+- API key inválida o expirada
+- Modelo no disponible
+
+**Soluciones:**
+
+1. **Verifica el estado de la cuota:**
+   ```
+   Dashboard → Providers → Ver el rastreador de cuota
+   ```
+   Si la cuota está agotada, espera el reinicio o cambia de proveedor.
+
+2. **Usa el fallback con combo:**
+   ```
+   Dashboard → Combos → Crea cadena de fallback
+   Ejemplo: cc/claude-opus → glm/glm-4.7 → if/kimi-k2
+   ```
+
+3. **Verifica la conexión del proveedor:**
+   ```
+   Dashboard → Providers → Reconecta si es necesario
+   ```
+
+---
+
+## Rate Limiting
+
+**Problema:** Errores "Rate limit exceeded" o "Too many requests".
+
+**Causas:**
+- Cuota de suscripción agotada (límites de 5 horas/diario/semanal)
+- Límites de tasa de API alcanzados
+- Demasiadas solicitudes concurrentes
+
+**Soluciones:**
+
+1. **Verifica el tiempo de reinicio:**
+   ```
+   Dashboard → Quota Tracking → Ver cuenta regresiva
+   ```
+
+2. **Cambia al nivel barato:**
+   ```
+   Usa: glm/glm-4.7 ($0.6/1M tokens)
+        minimax/MiniMax-M2.1 ($0.20/1M tokens)
+   ```
+
+3. **Agrega un combo de fallback:**
+   ```
+   Dashboard → Combos → Agrega modelos de respaldo
+   Principal: cc/claude-opus (suscripción)
+   Respaldo: glm/glm-4.7 (barato)
+   Emergencia: if/kimi-k2 (gratis)
+   ```
+
+---
+
+## Token OAuth expirado
+
+**Problema:** Errores "Unauthorized" o "Token expired".
+
+**Causas:**
+- Token OAuth expirado (refresh automático falló)
+- Sesión del proveedor invalidada
+- Problemas de red durante el refresh
+
+**Soluciones:**
+
+1. **Refresh automático (por defecto):**
+   9Router refresca automáticamente los tokens. Espera 30 segundos y reintenta.
+
+2. **Reconexión manual:**
+   ```
+   Dashboard → Providers → [Nombre del proveedor] → Reconnect
+   → Completa el flujo OAuth de nuevo
+   ```
+
+3. **Verifica el estado del proveedor:**
+   Verifica que el servicio del proveedor esté en línea (Claude Code, Codex, etc.)
+
+---
+
+## Costos altos
+
+**Problema:** Uso o costos altos inesperados.
+
+**Causas:**
+- Uso de modelos costosos innecesariamente
+- Sin fallback a niveles más baratos
+- Ventanas de contexto grandes
+
+**Soluciones:**
+
+1. **Verifica las estadísticas de uso:**
+   ```
+   Dashboard → Usage Stats → Ver consumo de tokens
+   → Identifica modelos de alto costo
+   ```
+
+2. **Cambia a modelos más baratos:**
+   ```
+   Reemplaza: cc/claude-opus (suscripción $20-100/mes)
+   Con: glm/glm-4.7 ($0.6/1M tokens)
+        minimax/MiniMax-M2.1 ($0.20/1M tokens)
+   ```
+
+3. **Usa el nivel gratis:**
+   ```
+   if/kimi-k2-thinking (GRATIS)
+   qw/qwen3-coder-plus (GRATIS)
+   kr/claude-sonnet-4.5 (GRATIS)
+   gc/gemini-3-flash-preview (GRATIS 180K/mes)
+   ```
+
+4. **Optimiza los prompts:**
+   - Reduce el tamaño del contexto
+   - Usa streaming para respuestas largas
+   - Cachea prompts comunes
+
+---
+
+## Connection Refused
+
+**Problema:** "ECONNREFUSED" o "Cannot connect to localhost:20128".
+
+**Causas:**
+- 9Router no está ejecutándose
+- Puerto 20128 bloqueado
+- Firewall bloqueando la conexión
+
+**Soluciones:**
+
+1. **Inicia 9Router:**
+   ```bash
+   9router
+   ```
+   El dashboard debe abrir en http://localhost:3000
+
+2. **Verifica el puerto 20128:**
+   ```bash
+   # Verifica si el puerto está escuchando
+   lsof -i :20128
+   
+   # O en Windows
+   netstat -ano | findstr :20128
+   ```
+
+3. **Revisa el firewall:**
+   - macOS: System Settings → Network → Firewall
+   - Windows: Windows Defender Firewall → Allow app
+   - Linux: `sudo ufw allow 20128`
+
+4. **Usa el endpoint en la nube:**
+   Si localhost no funciona (ej. Cursor IDE):
+   ```
+   Endpoint: https://9router.com/v1
+   ```
+
+---
+
+## El dashboard no abre
+
+**Problema:** El dashboard no carga en http://localhost:3000.
+
+**Causas:**
+- Puerto 3000 ya en uso
+- 9Router crasheó
+- Problemas de caché del navegador
+
+**Soluciones:**
+
+1. **Verifica si 9Router está ejecutándose:**
+   ```bash
+   # Verifica el proceso
+   ps aux | grep 9router
+   
+   # Verifica el puerto 3000
+   lsof -i :3000
+   ```
+
+2. **Mata el proceso en conflicto:**
+   ```bash
+   # macOS/Linux
+   lsof -ti:3000 | xargs kill -9
+   
+   # Windows
+   netstat -ano | findstr :3000
+   taskkill /PID <PID> /F
+   ```
+
+3. **Reinicia 9Router:**
+   ```bash
+   # Detener
+   pkill -f 9router
+   
+   # Iniciar
+   9router
+   ```
+
+4. **Limpia la caché del navegador:**
+   - Chrome: Ctrl+Shift+Delete → Limpiar caché
+   - Prueba en modo incógnito
+
+5. **Verifica la configuración del firewall:**
+   Asegúrate de que el puerto 3000 no esté bloqueado.
+
+---
+
+## Modelo no encontrado
+
+**Problema:** Errores "Model not found" o "Invalid model".
+
+**Causas:**
+- Proveedor no conectado
+- Error tipográfico en el ID del modelo
+- Proveedor inactivo
+
+**Soluciones:**
+
+1. **Verifica la conexión del proveedor:**
+   ```
+   Dashboard → Providers → Verifica estado (verde = activo)
+   ```
+
+2. **Revisa el formato del ID del modelo:**
+   ```
+   Correcto: cc/claude-opus-4-5-20251101
+   Incorrecto: claude-opus-4-5-20251101
+   
+   Formato: [prefijo-proveedor]/[nombre-modelo]
+   ```
+
+3. **Lista los modelos disponibles:**
+   ```bash
+   curl http://localhost:20128/v1/models \
+     -H "Authorization: Bearer your-api-key"
+   ```
+
+4. **Reconecta el proveedor:**
+   ```
+   Dashboard → Providers → [Proveedor] → Reconnect
+   ```
+
+---
+
+## Respuesta lenta
+
+**Problema:** Las solicitudes tardan demasiado o hacen timeout.
+
+**Causas:**
+- Latencia del proveedor
+- Problemas de red
+- Contexto/respuesta grande
+- Rate limiting del proveedor
+
+**Soluciones:**
+
+1. **Verifica el estado del proveedor:**
+   ```
+   Dashboard → Providers → Ver estadísticas de latencia
+   ```
+
+2. **Cambia a un modelo más rápido:**
+   ```
+   Rápidos: cc/claude-haiku-4-5 (Haiku es más rápido que Opus)
+         gc/gemini-3-flash-preview
+         qw/qwen3-coder-flash
+   ```
+
+3. **Usa streaming:**
+   ```json
+   {
+     "model": "cc/claude-opus-4-5",
+     "messages": [...],
+     "stream": true
+   }
+   ```
+
+4. **Verifica la red:**
+   ```bash
+   # Prueba la latencia
+   ping api.anthropic.com
+   ping api.openai.com
+   ```
+
+5. **Reduce el tamaño del contexto:**
+   - Recorta el historial de mensajes
+   - Usa prompts más pequeños
+   - Habilita el pruning de contexto en la herramienta CLI
+
+---
+
+## API Key inválida
+
+**Problema:** Errores "Invalid API key" o "Authentication failed".
+
+**Causas:**
+- API key incorrecta copiada
+- API key expirada
+- API key no generada
+
+**Soluciones:**
+
+1. **Regenera la API key:**
+   ```
+   Dashboard → Settings → API Keys → Generate New Key
+   → Copia y usa la nueva key
+   ```
+
+2. **Verifica el formato de la key:**
+   ```
+   Correcto: 9r_xxxxxxxxxxxxxxxxxxxxxxxx
+   Incorrecto: Falta el prefijo 9r_
+   ```
+
+3. **Verifica la key en la configuración del CLI:**
+   ```bash
+   # Cursor
+   Settings → Models → OpenAI API Key
+   
+   # Cline
+   Settings → API Key
+   
+   # Variable de entorno
+   export OPENAI_API_KEY="9r_your_key"
+   ```
+
+4. **Prueba la API key:**
+   ```bash
+   curl http://localhost:20128/v1/models \
+     -H "Authorization: Bearer 9r_your_key"
+   ```

+
+## 🌐 Nginxリバースプロキシ
+
+### Nginxを使う理由
+
+- SSL/TLS終端
+- ドメイン名マッピング
+- ロードバランシング
+- セキュリティ強化
+
+### ステップ1: Nginxをインストール
+
+```bash
+sudo apt update
+sudo apt install nginx
+```
+
+### ステップ2: Nginxを設定
+
+`/etc/nginx/sites-available/9router` を作成:
+
+```nginx
+server {
+    listen 80;
+    server_name your-domain.com;
+
+    # Redirect HTTP to HTTPS
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name your-domain.com;
+
+    # SSL certificates (use certbot to generate)
+    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
+
+    # SSL configuration
+    ssl_protocols TLSv1.2 TLSv1.3;
+    ssl_ciphers HIGH:!aNULL:!MD5;
+    ssl_prefer_server_ciphers on;
+
+    # Proxy to 9Router
+    location / {
+        proxy_pass http://localhost:3000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_cache_bypass $http_upgrade;
+        
+        # SSE support - CRITICAL for streaming
+        proxy_buffering off;
+        proxy_read_timeout 86400;
+    }
+
+    # API endpoint
+    location /v1 {
+        proxy_pass http://localhost:20128;
+        proxy_http_version 1.1;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        
+        # SSE support - CRITICAL for streaming
+        proxy_buffering off;
+        proxy_read_timeout 86400;
+    }
+}
+```
+
+### ステップ3: サイトを有効化
+
+```bash
+# シンボリックリンクを作成
+sudo ln -s /etc/nginx/sites-available/9router /etc/nginx/sites-enabled/
+
+# 設定をテスト
+sudo nginx -t
+
+# Nginxをリロード
+sudo systemctl reload nginx
+```
+
+### ステップ4: Let's EncryptでSSLをセットアップ
+
+```bash
+# certbotをインストール
+sudo apt install certbot python3-certbot-nginx
+
+# SSL証明書を取得
+sudo certbot --nginx -d your-domain.com
+
+# 自動更新は自動的に設定されます
+# 更新をテスト
+sudo certbot renew --dry-run
+```
+
+---
+
+## 🔒 セキュリティ考慮事項
+
+### 1. デフォルト認証情報を変更
+
+**重要:** デプロイ前に `JWT_SECRET` と `INITIAL_PASSWORD` を変更:
+
+```bash
+# 安全なJWTシークレットを生成
+openssl rand -base64 32
+
+# この値をJWT_SECRETに使用
+export JWT_SECRET="generated-secret-here"
+```
+
+### 2. ファイアウォール設定
+
+```bash
+# SSHを許可
+sudo ufw allow 22/tcp
+
+# HTTP/HTTPSを許可 (Nginx使用時)
+sudo ufw allow 80/tcp
+sudo ufw allow 443/tcp
+
+# リバースプロキシを使用しない場合、9Routerポートを許可
+sudo ufw allow 3000/tcp
+sudo ufw allow 20128/tcp
+
+# ファイアウォールを有効化
+sudo ufw enable
+```
+
+### 3. ダッシュボードアクセスを制限
+
+APIアクセスのみ必要な場合、ダッシュボードポートを制限:
+
+```bash
+# ダッシュボードへのlocalhostアクセスのみ許可
+sudo ufw deny 3000/tcp
+```
+
+SSHトンネル経由でダッシュボードにアクセス:
+
+```bash
+ssh -L 3000:localhost:3000 user@your-server.com
+# ブラウザで http://localhost:3000 を開く
+```
+
+### 4. 定期的な更新
+
+```bash
+# システムパッケージを更新
+sudo apt update && sudo apt upgrade -y
+
+# 9Routerを更新
+cd /path/to/9router/app
+git pull
+npm install
+npm run build
+pm2 restart 9router
+```
+
+### 5. バックアップ戦略
+
+```bash
+# データディレクトリをバックアップ
+tar -czf 9router-backup-$(date +%Y%m%d).tar.gz /var/lib/9router
+
+# 自動毎日バックアップ (crontabに追加)
+0 2 * * * tar -czf /backups/9router-$(date +\%Y\%m\%d).tar.gz /var/lib/9router
+```
+
+---
+
+## 📊 モニタリング
+
+### アプリケーションステータスを確認
+
+```bash
+# PM2ステータス
+pm2 status
+
+# ログを表示
+pm2 logs 9router --lines 100
+
+# リソースをモニタリング
+pm2 monit
+```
+
+### Nginxログ
+
+```bash
+# アクセスログ
+sudo tail -f /var/log/nginx/access.log
+
+# エラーログ
+sudo tail -f /var/log/nginx/error.log
+```
+
+### システムリソース
+
+```bash
+# CPUとメモリ使用量
+htop
+
+# ディスク使用量
+df -h
+
+# ネットワーク接続
+netstat -tulpn | grep -E '3000|20128'
+```
+
+---
+
+## 🚨 トラブルシューティング
+
+### アプリケーションが起動しない
+
+```bash
+# ログを確認
+pm2 logs 9router

+# コンボ - カスタムフォールバックチェーン
+
+自動フォールバック付きのカスタムモデル組み合わせを作成。コンボを使って、コスト、品質、可用性に基づく独自のルーティング戦略を定義できます。
+
+---
+
+## コンボとは?
+
+コンボはダッシュボードで作成する**カスタムフォールバックチェーン**です。単一モデルを使う代わりに、9Routerが順番に試すモデルのシーケンスを定義します。
+
+**例:**
+```
+コンボ名: premium-coding
+モデル:
+  1. cc/claude-opus-4-5-20251101 (最初に試行)
+  2. glm/glm-4.7 (#1のクォータ消費時)
+  3. minimax/MiniMax-M2.1 (#2のクォータ消費時)
+```
+
+**CLIでの使用:**
+```
+Model: premium-coding
+```
+
+9Routerは成功するまで各モデルを順番に自動的に試します。
+
+---
+
+## なぜコンボを使うのか?
+
+### 1. サブスクリプション価値を最大化
+```
+cc/claude-opus → glm/glm-4.7 → if/kimi-k2-thinking
+
+→ サブスクリプション優先、低価格バックアップ、無料緊急時
+→ すでに支払っているサブスクリプションから完全な価値を得る
+```
+
+### 2. コストを最小化
+```
+glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+
+→ 最安の有料オプションから開始 (100万あたり$0.60)
+→ さらに安いものへフォールバック (100万あたり$0.20)
+→ 緊急時の無料階層
+→ 総コスト: 月$5〜10 vs ChatGPT APIの$2000
+```
+
+### 3. 24時間可用性を確保
+```
+cc/claude-opus → cx/gpt-5.2-codex → glm/glm-4.7 → if/kimi-k2-thinking
+
+→ 最後に常に無料階層を含める
+→ クォータ切れにならない
+→ いつでもどこでもコーディング
+```
+
+### 4. 品質に最適化
+```
+cc/claude-opus-4-5 → cx/gpt-5.2-codex → gc/gemini-3-pro
+
+→ 最高のモデルが最初
+→ 他のプレミアムモデルへフォールバック
+→ フォールバックチェーン全体で高品質を維持
+```
+
+---
+
+## コンボの作成方法
+
+### ステップ1: ダッシュボードを開く
+
+```
+http://localhost:20128
+→ パスワードでログイン
+```
+
+### ステップ2: コンボへ移動

+    ],
+    "stream": true
+  }'
+```
+
+---
+
+## ベストプラクティス
+
+### 1. 常に無料階層を含める
+
+```
+✅ 良い:
+cc/claude-opus → glm/glm-4.7 → if/kimi-k2-thinking
+
+❌ 悪い:
+cc/claude-opus → glm/glm-4.7
+(無料フォールバックなし、クォータ切れの可能性)
+```
+
+**理由**: 24時間可用性を確保、クォータでブロックされない。
+
+### 2. コスト順に並べる (安価→高価)
+
+```
+✅ 良い:
+glm/glm-4.7 → minimax/MiniMax-M2.1 → cc/claude-opus
+
+❌ 悪い:
+cc/claude-opus → glm/glm-4.7
+(シンプルなタスクにサブスクリプションクォータを浪費)
+```
+
+**例外**: サブスクリプション価値を最大化したい場合は、サブスクリプションを最初に。
+
+### 3. 品質要件に合わせる
+
+```
+本番コードの場合:
+cc/claude-opus → cx/gpt-5.2-codex → glm/glm-4.7
+
+クイックタスクの場合:
+glm/glm-4.7 → if/kimi-k2-thinking
+
+実験用:
+if/kimi-k2-thinking → qw/qwen3-coder-plus
+```
+
+### 4. クォータリセット時間を考慮
+
+```
+朝のコンボ (新鮮なクォータ):
+cc/claude-opus → cx/gpt-5.2-codex
+
+夕方のコンボ (クォータが消費されている可能性):
+glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+```
+
+### 5. 異なるユースケース用に複数のコンボを作成
+
+```
+premium-coding: 複雑なタスク用
+budget-combo: シンプルなタスク用
+free-combo: 実験用
+quality-first: 本番コード用
+```
+
+**タスク要件に基づいてコンボを切り替え**ます。
+
+### 6. コンボパフォーマンスをモニター
+
+```
+Dashboard → Analytics → Combo Usage:
+  premium-coding:
+    80% cc/claude-opus経由 (良好、サブスクリプション使用)
+    15% glm/glm-4.7経由 (許容バックアップ)
+    5% minimax経由 (まれなフォールバック)
+```
+
+**最適化**: フォールバック使用が多すぎる場合、プライマリクォータを増やすかモデルを並べ替え。
+
+---
+
+## 高度な設定
+
+### コンボごとに予算上限を設定
+
+```
+Dashboard → Combos → Edit → Budget:
+  Daily limit: $5
+  Monthly limit: $50
+```
+
+上限に達すると、9Routerは有料モデルをスキップして無料階層のみを使用。
+
+### コンボ内のモデルを有効/無効
+
+```
+Dashboard → Combos → Edit → Models:
+  ✅ cc/claude-opus-4-5 (有効)
+  ❌ glm/glm-4.7 (一時的に無効)
+  ✅ if/kimi-k2-thinking (有効)
+```
+
+**ユースケース**: コンボを削除せずに高価なモデルを一時的に無効化。
+
+### 既存のコンボを複製
+
+```
+Dashboard → Combos → Clone "premium-coding"
+→ "-copy" サフィックス付きのコピーを作成
+→ 変更して新しいコンボとして保存
+```
+
+**ユースケース**: 異なるシナリオ用のバリエーションを作成。
+
+---
+
+## トラブルシューティング
+
+**問題: コンボがモデルリストに表示されない**
+
+**解決策:**
+1. ダッシュボードを更新
+2. コンボが保存されていることを確認 (緑のチェック)
+3. CLIツールを再起動してモデルリストを更新
+
+**問題: コンボが常に最後のモデル (無料階層) を使用**
+
+**解決策:**
+1. プライマリモデルのクォータを確認 (Dashboard → Quota)
+2. APIキーが有効か確認 (Dashboard → Providers)
+3. 予算上限を超えていないか確認
+
+**問題: コンボのコストが予想より高い**
+
+**解決策:**
+1. Dashboard → Analytics → コンボ使用量を確認
+2. プライマリモデルがクォータ切れか確認
+3. モデルを並べ替え (安価を先に)
+4. 予算上限を設定

+```
+
+---
+
+## ベストプラクティス
+
+### 1. クォータを毎日モニター
+
+```
+日課:
+1. ダッシュボードクォータ概要を確認 (30秒)
+2. リセット時間を確認
+3. クォータ可用性に合わせて使用量を計画
+```
+
+**例:**
+```
+朝の確認:
+  ✅ Claude Code: 5時間利用可 (新鮮なリセット)
+  ✅ Gemini CLI: 1Kリクエスト利用可
+  ⚠️ GLM-4.7: 2Mトークン残 (午前10時リセット)
+  
+アクション: 朝の作業にClaude Codeを使用
+```
+
+### 2. 予算上限を設定
+
+```
+Dashboard → Settings → Budget:
+  Daily: $5 (使いすぎ防止)
+  Monthly: $150 (予算に整合)
+```
+
+**結果**: 上限到達時に自動的に無料階層へ切替。
+
+### 3. コンボ使用を最適化
+
+```
+Dashboard → Analytics → Combos:
+  どのモデルが最もよく使われているか確認
+  コストを最小化するためにコンボ順序を調整
+```
+
+**例:**
+```
+現在: cc/claude-opus → glm/glm-4.7
+  80% Claude経由 (良好)
+  20% GLM経由 ($12/月)
+
+最適化後: gc/gemini-3-flash → cc/claude-opus → glm/glm-4.7
+  50% Gemini経由 (無料)
+  40% Claude経由 (サブスクリプション)
+  10% GLM経由 ($6/月)
+  
+節約: $6/月
+```
+
+### 4. リセット時間を追跡
+
+```
+Dashboard → Quota → Reset Schedule:
+  Claude Code: 5時間ローリング + 週次月曜
+  Gemini CLI: 日次 00:00 UTC + 月次 1日
+  GLM-4.7: 毎日午前10時 北京時間
+  MiniMax: 5時間ローリングウィンドウ
+```
+
+**戦略**: クォータが新鮮な時にプロバイダーを使用。
+
+### 5. 月次レポートを確認
+
+```
+Dashboard → Analytics → Monthly Report:
+  Total tokens: 1.5B
+  Total cost: $120
+  Savings: 97% vs ChatGPT API
+  
+インサイト:
+  - 60% サブスクリプション経由の使用 ($0)
+  - 30% GLM経由 ($90)
+  - 10% 無料階層経由 ($0)
+  
+最適化:
+  - Gemini CLI使用を増やす (無料)
+  - GLM使用を減らす (高価)

+# スマートルーティングと自動フォールバック
+
+9Routerは3階層フォールバックシステムを使用して、最適な利用可能なプロバイダーへリクエストを自動的にルーティングします。クォータ制限やレート制限でコーディングが止まることはありません。
+
+---
+
+## 動作の仕組み
+
+9Routerは、既存のサブスクリプションを最大化し、コストを最小化し、24時間可用性を確保するため、インテリジェントなルーティングを使用します:
+
+```
+Request → 9Router → Tier 1を確認 (サブスクリプション)
+                     ↓ クォータ消費
+                     Tier 2を確認 (低価格)
+                     ↓ 予算上限
+                     Tier 3を確認 (無料)
+                     ↓
+                     Response
+```
+
+### 3階層フォールバックシステム
+
+**Tier 1: サブスクリプション (プライマリ)**
+- Claude Code (Pro/Max)
+- OpenAI Codex (Plus/Pro)
+- Gemini CLI (月18万無料)
+- GitHub Copilot
+- Antigravity (Google)
+
+**目標**: すでに支払っているサブスクリプションから価値を最大化。
+
+**Tier 2: 低価格 (バックアップ)**
+- GLM-4.7 (入力100万あたり$0.60)
+- MiniMax M2.1 (入力100万あたり$0.20)
+- Kimi K2 (月$9固定)
+
+**目標**: サブスクリプションクォータ切れ時の超低価格バックアップ (ChatGPT APIより約90%安い)。
+
+**Tier 3: 無料 (緊急時)**
+- iFlow (8モデル)
+- Qwen (3モデル)
+- Kiro (Claude無料)
+
+**目標**: 無制限コーディング用のゼロコストフォールバック。
+
+---
+
+## 自動切替
+
+9Routerはクォータをリアルタイムでモニターし、プロバイダーを自動的に切り替えます:
+
+### シナリオ1: サブスクリプションクォータ消費
+
+```
+ユーザーリクエスト → cc/claude-opus-4-5
+               ↓ クォータ消費 (5時間制限到達)
+               自動切替 → glm/glm-4.7
+               ↓ 日次クォータ消費
+               自動切替 → minimax/MiniMax-M2.1
+               ↓ 5時間クォータ消費
+               自動切替 → if/kimi-k2-thinking (無料)
+               ↓
+               レスポンス配信 ✅
+```
+
+**結果**: ダウンタイムゼロ、シームレスな体験。
+
+### シナリオ2: レート制限
+
+```
+ユーザーリクエスト → cx/gpt-5.2-codex
+               ↓ レート制限 (リクエストが多すぎ)
+               自動切替 → glm/glm-4.7
+               ↓
+               レスポンス配信 ✅
+```
+
+### シナリオ3: プロバイダー利用不可
+
+```
+ユーザーリクエスト → cc/claude-opus-4-5
+               ↓ プロバイダーエラー (503)
+               自動切替 → 次の利用可能なモデル
+               ↓
+               レスポンス配信 ✅
+```
+
+---
+
+## モデル選択ロジック
+
+9Routerは以下に基づいて最適なモデルを選択します:
+
+1. **クォータ可用性** - プロバイダーに残量があるか確認
+2. **コスト階層** - サブスクリプション → 低価格 → 無料を優先
+3. **リセットタイミング** - クォータリセット時を考慮
+4. **プロバイダー健全性** - エラーのあるプロバイダーをスキップ
+
+### 優先順位の例
+
+`cc/claude-opus-4-5` へのリクエストの場合:
+
+```
+1. Claude Codeクォータを確認
+   ✅ 利用可 → cc/claude-opus-4-5を使用
+   ❌ 消費 → ステップ2へ
+
+2. フォールバック階層を確認 (設定されている場合)
+   ✅ GLMクォータ利用可 → glm/glm-4.7を使用
+   ❌ 消費 → ステップ3へ
+
+3. 無料階層を確認
+   ✅ iFlow利用可 → if/kimi-k2-thinkingを使用
+   ❌ すべて消費 → クォータエラーを返す
+```
+
+---
+
+## 設定オプション
+
+### ダッシュボード設定
+
+**1. 自動フォールバックを有効/無効化**
+
+```
+Dashboard → Settings → Smart Routing
+→ 「Auto Fallback」をオン/オフに切替
+```
+
+- **オン** (デフォルト): 自動階層切替
+- **オフ**: 厳格モード、プライマリモデル利用不可時にエラーを返す
+
+**2. 予算上限を設定**
+
+```
+Dashboard → Settings → Budget Control
+→ 日次上限: $5
+→ 月次上限: $50
+```
+
+予算到達時、9Routerは自動的に無料階層へ切替。
+
+**3. フォールバック順序を設定**
+
+```
+Dashboard → Settings → Fallback Priority
+→ 各階層内でプロバイダーをドラッグして並べ替え
+```
+
+カスタム順序の例:
+```
+Tier 1: Gemini CLI → Claude Code → Codex
+Tier 2: MiniMax → GLM → Kimi
+Tier 3: iFlow → Kiro → Qwen
+```
+
+**4. クォータリセット通知**
+
+```
+Dashboard → Settings → Notifications
+→ クォータリセット時にメール
+→ 80%クォータ使用時にアラート
+```
+
+---
+
+## 例
+
+### 例1: 基本的な自動フォールバック
+
+**セットアップ:**
+```
+Model: cc/claude-opus-4-5-20251101
+Fallback: 自動 (デフォルト3階層)
+```
+
+**動作:**
+```
+朝 (新鮮なクォータ):
+  Request → cc/claude-opus-4-5 ✅
+
+午後 (クォータ消費):
+  Request → glm/glm-4.7 ✅ (自動切替)
+
+夕方 (GLMクォータ切れ):
+  Request → minimax/MiniMax-M2.1 ✅ (自動切替)
+
+深夜 (すべての有料クォータ切れ):
+  Request → if/kimi-k2-thinking ✅ (無料階層)
+```
+
+**コスト**: 月$5〜10の追加料金 (主にサブスクリプションでカバー)。
+
+### 例2: 予算意識のルーティング
+
+**セットアップ:**
+```
+Dashboard → Settings:
+  Daily budget: $2
+  Monthly budget: $20
+  Fallback: 有効
+```
+
+**動作:**
+```
+1〜15日 (予算内):
+  Requests → glm/glm-4.7 (低価格階層)
+  コスト: $1.50/日
+
+16日 (予算到達):
+  Requests → if/kimi-k2-thinking (無料階層)
+  コスト: $0
+
+翌月 (予算リセット):
+  Requests → 再びglm/glm-4.7
+```
+
+**結果**: 月$20を超えない、常に利用可能。
+
+### 例3: サブスクリプションのみモード
+
+**セットアップ:**
+```
+Dashboard → Settings:
+  Auto Fallback: オフ
+  Strict mode: オン
+```
+
+**動作:**
+```
+Request → cc/claude-opus-4-5
+  ✅ クォータ利用可 → 成功
+  ❌ クォータ消費 → エラーを返す (フォールバックなし)
+```
+
+**ユースケース**: 有料サブスクリプションのみを使用したい場合、追加コストなし。
+
+### 例4: 無料のみモード
+
+**セットアップ:**
+```
+Model: if/kimi-k2-thinking
+Fallback: qw/qwen3-coder-plus → kr/claude-sonnet-4.5
+```
+
+**動作:**
+```
+すべてのリクエスト → 無料階層のみ
+コスト: 永久に$0
+```
+
+**ユースケース**: 個人プロジェクト、学習、実験。
+
+---
+
+## ベストプラクティス
+
+### 1. サブスクリプション価値を最大化
+
+```
+戦略:
+- サブスクリプションモデルをTier 1に設定
+- ダッシュボードでクォータ使用量をモニター
+- サブスクリプション消費時のみ低価格階層を使用
+```
+
+**コンボ例:**
+```
+cc/claude-opus-4-5 → glm/glm-4.7 → if/kimi-k2-thinking
+```
+
+### 2. コストに最適化
+
+```
+戦略:
+- Gemini CLI無料階層を最初に使用 (月18万)
+- GLM/MiniMaxへフォールバック (超低価格)
+- 緊急時: iFlow (無料)
+```
+
+**コンボ例:**
+```
+gc/gemini-3-flash-preview → glm/glm-4.7 → if/kimi-k2-thinking
+```
+
+### 3. 品質に最適化
+
+```
+戦略:
+- 最高のモデルを使用 (Claude Opus、GPT-5.2)
+- 良質な低価格モデルへフォールバック (GLM-4.7)
+- 最後の手段: 無料階層
+```
+
+**コンボ例:**
+```
+cc/claude-opus-4-5 → cx/gpt-5.2-codex → glm/glm-4.7
+```
+
+### 4. 24時間可用性
+
+```
+戦略:
+- フォールバックに常に無料階層を含める
+- クォータリセット時間をモニター
+- プロバイダー間で使用量を分散
+```
+
+**コンボ例:**
+```
+cc/claude-opus-4-5 → glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+```
+
+**結果**: クォータ切れにならない、いつでもコーディング。
+
+---
+
+## クォータリセット戦略
+
+クォータリセット時間に合わせて使用量を計画:
+
+| プロバイダー | クォータリセット | 戦略 |
+|----------|-------------|----------|
+| **Claude Code** | 5時間 + 週次 | 朝、新鮮なクォータを使用 |
+| **Codex** | 5時間 + 週次 | Claudeクォータ切れ後に使用 |
+| **Gemini CLI** | 日次 (1K) + 月次 (18万) | 一日中使用 |
+| **GLM-4.7** | 毎日午前10時 | 夕方使用、翌朝リセット |
+| **MiniMax M2.1** | 5時間ローリング | いつでも使用、ローリングウィンドウを追跡 |
+| **iFlow/Qwen/Kiro** | 制限なし | 緊急時バックアップ |
+
+**日課の例:**
+```
+08:00 - 13:00: Claude Code (新鮮な5時間クォータ)
+13:00 - 18:00: Gemini CLI (1K/日クォータ)
+18:00 - 22:00: GLM-4.7 (低価格、午前10時リセット)
+22:00 - 08:00: MiniMaxまたはiFlow (5時間ローリングまたは無料)
+```
+
+---
+
+## モニタリングとアラート
+
+### ダッシュボードクォータトラッカー
+
+```
+Dashboard → Quota Overview:
+  Claude Code: 2.5h / 5h 残 (50%)
+  Gemini CLI: 今日 450 / 1000 リクエスト
+  GLM-4.7: 5M / 10M トークン (8時間後リセット)
+  MiniMax: 3M / 5M トークン (5時間ローリング)
+```
+
+### リアルタイム通知
+
+```
+Dashboard → Notifications:
+  ⚠️ Claude Codeクォータ80%使用 (1時間残)
+  ✅ GLM-4.7クォータリセット (10Mトークン利用可)
+  💰 日次予算50%使用 ($2.50 / $5)
+```
+
+### 使用統計
+
+```
+Dashboard → Analytics:
+  今日: 5000万トークン
+    - 3000万 Claude Code経由 (サブスクリプション)
+    - 1500万 GLM-4.7経由 ($9)
+    - 500万 iFlow経由 (無料)
+  
+  コスト: $9 (vs ChatGPT APIの$1000)
+  節約: 99%
+```
+
+---
+
+## トラブルシューティング
+
+**問題: "All providers quota exhausted"**
+
+**解決策:**
+1. ダッシュボードクォータトラッカーを確認
+2. クォータリセットを待つ (カウントダウン参照)
+3. フォールバックチェーンに無料階層を追加
+4. または予算上限を増やす
+
+**問題: "Too many fallback switches"**
+
+**解決策:**
+1. プライマリプロバイダーがダウンしているか確認
+2. クォータ上限を増やす (サブスクリプションをアップグレード)
+3. より安いプライマリモデルを使用 (Claudeの代わりにGLM)
+
+**問題: "Unexpected costs"**
+
+**解決策:**
+1. Dashboard → Analytics → 使用量を確認
+2. 日次/月次予算上限を設定
+3. クリティカルでないタスクは無料階層へ切替
+4. 無料フォールバック付きのコンボを使用

+# はじめに
+
+9Routerを5分で起動し、AIリクエストをインテリジェントにルーティングし始めましょう。
+
+---
+
+## クイックスタート
+
+### 1. インストール
+
+```bash
+npm install -g 9router
+```
+
+**要件:** Node.js 20+ ([インストール詳細](getting-started/installation.md))
+
+### 2. 起動
+
+```bash
+9router
+```
+
+🎉 **ダッシュボードが自動的に開きます** (`http://localhost:20128`)
+
+- デフォルトパスワード: `123456` (ダッシュボードで変更)
+- APIキーは自動生成
+- プロバイダー接続の準備完了
+
+### 3. プロバイダーを接続
+
+プロバイダーを接続する方法は3つあります:
+
+#### オプションA: OAuth(サブスクリプションプロバイダー)
+
+**最適:** Claude Code、Codex、Gemini CLI、GitHub Copilot
+
+```
+Dashboard → Providers → Connect [Provider]
+→ OAuthログイン → トークン自動更新
+→ クォータトラッキング有効化
+```
+
+**例: Claude Code**
+1. 「Connect Claude Code」をクリック
+2. Claudeアカウントでログイン
+3. 9Routerを認可
+4. ✅ 完了! モデルを使用: `cc/claude-opus-4-5-20251101`
+
+#### オプションB: APIキー(低価格プロバイダー)
+
+**最適:** GLM、MiniMax、Kimi、OpenRouter
+
+```
+Dashboard → Providers → Add API Key
+→ プロバイダーを選択
+→ APIキーを貼り付け
+→ 保存
+```
+
+**例: GLM-4.7**
+1. [Zhipu AI](https://open.bigmodel.cn/)でサインアップ
+2. Coding PlanからAPIキーを取得
+3. Dashboard → Add API Key → Provider: `glm` → キーを貼り付け
+4. ✅ 完了! モデルを使用: `glm/glm-4.7`
+
+#### オプションC: 無料プロバイダー(コストなし)
+
+**最適:** iFlow、Qwen、Kiro
+
+```
+Dashboard → Providers → Connect [Free Provider]
+→ デバイスコードまたはOAuth
+→ 無制限利用
+```
+
+**例: iFlow**
+1. 「Connect iFlow」をクリック
+2. iFlowアカウントでログイン
+3. 認可
+4. ✅ 完了! 8モデルを使用: `if/kimi-k2-thinking`、`if/qwen3-coder-plus`など
+
+---
+
+## 4. CLIツールで使用
+
+コーディングツールを9Routerに向けます:
+
+### Cursor IDE
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [9routerダッシュボードから取得]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+### Claude Desktop
+
+`~/.claude/config.json`を編集:
+
+```json
+{
+  "anthropic_api_base": "http://localhost:20128/v1",
+  "anthropic_api_key": "your-9router-api-key"
+}
+```
+
+### Cline / Continue / RooCode
+
+```
+Provider: OpenAI Compatible
+Base URL: http://localhost:20128/v1
+API Key: [ダッシュボードから取得]
+Model: cc/claude-opus-4-5-20251101
+```
+
+### Codex CLI
+
+```bash
+export OPENAI_BASE_URL="http://localhost:20128"
+export OPENAI_API_KEY="your-9router-api-key"
+
+codex "your prompt"
+```
+
+---
+
+## 5. スマートコンボを作成(オプション)
+
+コンボはモデル間の自動フォールバックを可能にします:
+
+```
+Dashboard → Combos → Create New
+
+Name: premium-coding
+Models:
+  1. cc/claude-opus-4-5-20251101 (サブスクリプション優先)
+  2. glm/glm-4.7 (低価格バックアップ、100万あたり$0.6)
+  3. if/kimi-k2-thinking (無料フォールバック)
+
+CLIで使用: premium-coding
+```
+
+**動作:**
+1. 最初にClaude Opusを試行(サブスクリプション)
+2. クォータ消費時 → GLM-4.7(超低価格)
+3. 予算上限時 → iFlow(無料)
+4. ダウンタイムゼロ、自動切替!
+
+---

+→ 遅い作業の低価格フォールバック
+
+夜: 無料階層 (iFlow)
+→ ゼロコスト緊急バックアップ
+```
+
+### 戦略2: 予算優先
+
+```
+月次予算設定: $20
+
+割り当て:
+- $9 Kimi K2 (1000万トークン固定)
+- $6 GLM日次クォータ (1000万トークン)
+- $5 MiniMaxオーバーフロー (2500万トークン)
+
+合計: $20で4500万トークン
+vs ChatGPT APIでは$20で100万トークン!
+```
+
+### 戦略3: サブスクリプションを最初に最大化
+
+```
+優先順位:
+1. Gemini CLI (月18万無料)
+2. Claude Code (すでに支払っているサブスクリプション)
+3. GLM-4.7 (低価格バックアップ、100万あたり$0.6)
+4. MiniMax M2.1 (最安、100万あたり$0.2)
+5. iFlow (無料緊急時)
+
+月次コスト例 (1億トークン):
+- Gemini CLI経由で6000万: $0 (無料)
+- Claude Code経由で3000万: $0 (サブスクリプション)
+- GLM経由で800万: $4.80
+- MiniMax経由で200万: $0.40
+合計: 月$5.20!
+```
+
+---
+
+## 実例
+
+### 例1: 重いコーディング月 (1億トークン)
+
+```
+内訳:
+- サブスクリプション (Claude/Codex) 経由で6000万: $0追加
+- GLM-4.7経由で3000万: $18
+- MiniMax M2.1経由で1000万: $2
+
+合計: 月$20
+vs ChatGPT APIの$2000!
+
+節約: 99%安い!
+```
+
+### 例2: バジェットコーダー ($10/月)
+
+```
+戦略:
+- $9 Kimi K2 (1000万トークン)
+- $1 MiniMaxオーバーフロー (500万トークン)
+
+合計: $10で1500万トークン
+vs ChatGPT APIでは$10で50万トークン!
+
+30倍多くのトークン!
+```
+
+### 例3: フリーランサー (変動使用量)
+
+```
+軽い月 (2000万トークン):
+- サブスクリプション経由で1500万: $0
+- GLM経由で500万: $3
+合計: $3
+
+重い月 (1.5億トークン):
+- サブスクリプション経由で6000万: $0
+- GLM経由で6000万: $36
+- MiniMax経由で3000万: $6
+合計: $42
+
+平均: 月$22.50
+vs ChatGPT APIの$3400!
+```
+
+---
+
+## ベストプラクティス
+
+### 1. 日次クォータを追跡
+
+```
+ダッシュボード表示:
+- GLMクォータ: 75%使用 (6時間後リセット)
+- MiniMaxクォータ: 50%使用 (2時間後リセット)
+- Kimiクォータ: 800万/1000万使用 (15日後リセット)
+
+リセット時間に合わせて重いタスクを計画!
+```
+
+### 2. Coding Planを使用 (GLM)
+
+```
+Standard: 1×クォータ
+Coding Plan: 3×クォータ (同じ価格!)
+
+→ 常にCoding Planを選択
+```
+
+### 3. 無料階層と組み合わせる
+
+```
+コンボ:
+1. gc/gemini-3-flash (無料プライマリ)
+2. glm/glm-4.7 (低価格バックアップ)
+3. minimax/MiniMax-M2.1 (最安)
+4. if/kimi-k2-thinking (無料緊急時)
+
+結果: コストを最小化、アップタイムを最大化
+```
+
+### 4. 予算アラートを設定
+
+```
+Dashboard → Settings → Budget Alerts
+
+日次: $2上限
+週次: $10上限
+月次: $30上限
+
+→ 上限到達時に自動的に無料階層へ切替
+```
+
+---
+
+## トラブルシューティング
+
+### 「クォータ消費」
+
+**解決策:**
+- GLM: 北京時間午前10時まで待つ
+- MiniMax: 最初の使用から5時間待つ
+- Kimi: 翌月1日まで待つ
+- 無料階層へのコンボフォールバックを使用
+
+### 「APIキー無効」
+
+**解決策:**
+- APIキーが正しくコピーされたか確認
+- アカウントにクレジットがあるか確認
+- 必要に応じてAPIキーを再生成
+
+### 「高コスト」
+
+**解決策:**
+- ダッシュボードで使用統計を確認
+- 予算アラートを設定
+- MiniMax (100万あたり$0.2最安) へ切替
+- クリティカルでないタスクに無料階層を使用
+

+## 使用例
+
+### Cursor IDEセットアップ
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [9routerダッシュボードから取得]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+### コンボを作成 (推奨)
+
+```
+Dashboard → Combos → Create New
+
+Name: premium-coding
+Models:
+  1. gc/gemini-3-flash-preview (無料、最初に使用)
+  2. cc/claude-opus-4-5-20251101 (サブスクリプション)
+  3. cx/gpt-5.2-codex (サブスクリプションバックアップ)
+
+CLIで使用: premium-coding
+```
+
+**結果:** 無料階層を最大化 → サブスクリプションを使用 → 自動フォールバック
+
+---
+
+## クォータトラッキング
+
+9Routerはクォータをリアルタイムで追跡:
+
+- **トークン消費** - リクエストごとの入出力トークン
+- **リセットカウントダウン** - 次のクォータリセットまでの時間
+- **使用量パーセンテージ** - クォータの使用量
+- **自動フォールバック** - 消費時に次の階層へ切替
+
+**ダッシュボード表示:**
+
+```
+Claude Code Pro
+├─ Quota: 75% used
+├─ Reset: 2h 15m (5-hour)
+├─ Weekly reset: 3 days
+└─ Fallback: glm/glm-4.7 (cheap tier)
+```
+
+---
+
+## ベストプラクティス
+
+### 1. 無料階層を最初に使用
+
+```
+優先順位:
+1. Gemini CLI (月18万無料)
+2. Antigravity (無料Claude)
+3. Claude Code/Codex (有料サブスクリプション)
+```
+
+### 2. クォータを毎日追跡
+
+- 毎朝ダッシュボードを確認
+- クォータリセットに合わせて重いタスクを計画
+- クリティカルでないタスクには低価格/無料階層を使用
+
+### 3. スマートコンボを作成
+
+```
+コンボ例:
+1. gc/gemini-3-flash-preview (無料プライマリ)
+2. cc/claude-opus-4-5 (複雑なタスク)
+3. glm/glm-4.7 (低価格バックアップ)
+4. if/kimi-k2-thinking (無料フォールバック)
+```
+
+### 4. 時間別に最適化
+
+```
+朝: 新鮮な5時間クォータ (Claude/Codex)
+午後: Gemini CLI (1K/日)
+夕方: サブスクリプションクォータ
+夜: 低価格/無料階層
+```
+
+---
+
+## トラブルシューティング
+
+### 「クォータ消費」
+
+**解決策:**
+- ダッシュボードクォータトラッカーを確認
+- リセットを待つ (5時間または日次)
+- 低価格/無料階層へのコンボフォールバックを使用
+
+### 「OAuthトークン期限切れ」
+
+**解決策:**
+- 9Routerにより自動更新
+- 問題がある場合: Dashboard → Provider → Reconnect
+
+### 「レート制限」
+
+**解決策:**
+- サブスクリプションクォータ切れ
+- フォールバックを追加: `cc/claude-opus → glm/glm-4.7`
+- 無料階層を使用: `if/kimi-k2-thinking`
+
+---
+
+## 次のステップ
+
+- **低価格バックアップをセットアップ:** [低価格プロバイダー](./cheap.md)
+- **無料フォールバックを追加:** [無料プロバイダー](./free.md)
+- **コンボを作成:** Dashboard → Combos → Create New

+   置換: cc/claude-opus (月$20〜100サブスクリプション)
+   へ: glm/glm-4.7 (100万トークンあたり$0.6)
+       minimax/MiniMax-M2.1 (100万トークンあたり$0.20)
+   ```
+
+3. **無料階層を使用:**
+   ```
+   if/kimi-k2-thinking (無料)
+   qw/qwen3-coder-plus (無料)
+   kr/claude-sonnet-4.5 (無料)
+   gc/gemini-3-flash-preview (月18万無料)
+   ```
+
+4. **プロンプトを最適化:**

+
+# Monitor resources
+pm2 monit
+```
+
+---
+
+## 🐳 Triển khai Docker
+
+### Cách 1: Dùng Dockerfile
+
+Tạo `Dockerfile` trong thư mục `app`:
+
+```dockerfile
+FROM node:20-alpine
+
+WORKDIR /app
+
+# Copy package files
+COPY package*.json ./
+
+# Install dependencies
+RUN npm ci --only=production
+
+# Copy application files
+COPY . .
+
+# Build application
+RUN npm run build
+
+# Expose ports
+EXPOSE 3000 20128
+
+# Set environment variables
+ENV NODE_ENV=production
+ENV DATA_DIR=/app/data
+
+# Create data directory
+RUN mkdir -p /app/data
+
+# Start application
+CMD ["npm", "run", "start"]
+```
+
+**Build và Run:**
+
+```bash
+# Build image
+docker build -t 9router .
+
+# Run container
+docker run -d \
+  --name 9router \
+  -p 3000:3000 \
+  -p 20128:20128 \
+  -e JWT_SECRET="your-secure-secret-change-this" \
+  -e INITIAL_PASSWORD="your-secure-password" \
+  -v 9router-data:/app/data \
+  9router
+```
+
+### Cách 2: Docker Compose
+
+Tạo `docker-compose.yml`:
+
+```yaml
+version: '3.8'
+
+services:
+  9router:
+    build: .
+    container_name: 9router
+    ports:
+      - "3000:3000"
+      - "20128:20128"
+    environment:
+      - NODE_ENV=production
+      - JWT_SECRET=your-secure-secret-change-this
+      - INITIAL_PASSWORD=your-secure-password
+      - DATA_DIR=/app/data
+    volumes:
+      - 9router-data:/app/data
+    restart: unless-stopped
+
+volumes:
+  9router-data:
+```
+
+**Chạy với Docker Compose:**
+
+```bash
+# Start services
+docker-compose up -d
+

+## 🌐 Reverse Proxy với Nginx
+
+### Tại sao dùng Nginx?
+
+- Terminate SSL/TLS
+- Map domain
+- Load balancing
+- Bảo mật tốt hơn
+
+### Bước 1: Cài đặt Nginx
+
+```bash
+sudo apt update
+sudo apt install nginx
+```
+
+### Bước 2: Cấu hình Nginx
+
+Tạo `/etc/nginx/sites-available/9router`:
+
+```nginx
+server {
+    listen 80;
+    server_name your-domain.com;
+
+    # Redirect HTTP to HTTPS
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name your-domain.com;
+
+    # SSL certificates (use certbot to generate)
+    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
+
+    # SSL configuration
+    ssl_protocols TLSv1.2 TLSv1.3;
+    ssl_ciphers HIGH:!aNULL:!MD5;
+    ssl_prefer_server_ciphers on;
+
+    # Proxy to 9Router
+    location / {

+        proxy_pass http://localhost:20128;
+        proxy_http_version 1.1;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        
+        # SSE support - CRITICAL for streaming
+        proxy_buffering off;
+        proxy_read_timeout 86400;
+    }
+}
+```
+
+### Bước 3: Enable Site
+
+```bash
+# Create symbolic link
+sudo ln -s /etc/nginx/sites-available/9router /etc/nginx/sites-enabled/
+
+# Test configuration
+sudo nginx -t
+
+# Reload Nginx
+sudo systemctl reload nginx
+```
+
+### Bước 4: Setup SSL với Let's Encrypt
+
+```bash
+# Install certbot
+sudo apt install certbot python3-certbot-nginx
+
+# Obtain SSL certificate
+sudo certbot --nginx -d your-domain.com
+
+# Auto-renewal is configured automatically
+# Test renewal
+sudo certbot renew --dry-run
+```
+
+---
+
+## 🔒 Cân nhắc về Bảo mật
+
+### 1. Đổi credentials mặc định
+
+**QUAN TRỌNG:** Đổi `JWT_SECRET` và `INITIAL_PASSWORD` trước khi deploy:
+
+```bash
+# Generate secure JWT secret
+openssl rand -base64 32
+
+# Use this value for JWT_SECRET
+export JWT_SECRET="generated-secret-here"
+```
+
+### 2. Cấu hình Firewall
+
+```bash
+# Allow SSH
+sudo ufw allow 22/tcp
+
+# Allow HTTP/HTTPS (if using Nginx)
+sudo ufw allow 80/tcp
+sudo ufw allow 443/tcp
+
+# If NOT using reverse proxy, allow 9Router ports
+sudo ufw allow 3000/tcp
+sudo ufw allow 20128/tcp
+
+# Enable firewall
+sudo ufw enable
+```
+
+### 3. Giới hạn truy cập Dashboard
+
+Nếu chỉ cần truy cập API, giới hạn port dashboard:
+
+```bash
+# Only allow localhost access to dashboard
+sudo ufw deny 3000/tcp
+```
+
+Truy cập dashboard qua SSH tunnel:
+
+```bash
+ssh -L 3000:localhost:3000 user@your-server.com
+# Then open http://localhost:3000 in your browser
+```
+
+### 4. Cập nhật định kỳ
+
+```bash
+# Update system packages
+sudo apt update && sudo apt upgrade -y
+
+# Update 9Router
+cd /path/to/9router/app
+git pull
+npm install
+npm run build
+pm2 restart 9router
+```
+
+### 5. Chiến lược Backup
+
+```bash
+# Backup data directory
+tar -czf 9router-backup-$(date +%Y%m%d).tar.gz /var/lib/9router
+
+# Automated daily backup (add to crontab)
+0 2 * * * tar -czf /backups/9router-$(date +\%Y\%m\%d).tar.gz /var/lib/9router
+```
+
+---
+
+## 📊 Giám sát
+
+### Kiểm tra trạng thái Application
+
+```bash
+# PM2 status
+pm2 status
+
+# View logs
+pm2 logs 9router --lines 100
+
+# Monitor resources
+pm2 monit
+```
+
+### Nginx Logs
+
+```bash
+# Access logs
+sudo tail -f /var/log/nginx/access.log
+
+# Error logs
+sudo tail -f /var/log/nginx/error.log
+```
+
+### Tài nguyên hệ thống
+
+```bash
+# CPU and memory usage
+htop
+
+# Disk usage
+df -h
+
+# Network connections
+netstat -tulpn | grep -E '3000|20128'
+```
+
+---
+
+## 🚨 Troubleshooting
+
+### Application không khởi động
+
+```bash
+# Check logs
+pm2 logs 9router
+
+# Check if ports are in use
+sudo lsof -i :3000
+sudo lsof -i :20128
+
+# Check environment variables
+pm2 env 9router
+```
+
+### Nginx 502 Bad Gateway
+
+```bash
+# Check if 9Router is running
+pm2 status
+
+# Check Nginx error logs
+sudo tail -f /var/log/nginx/error.log
+
+# Test Nginx configuration
+sudo nginx -t
+```
+
+### SSE Streaming không hoạt động
+
+Đảm bảo `proxy_buffering off` được set trong cấu hình Nginx để hỗ trợ SSE.
+
+### Lỗi Permission Denied
+
+```bash
+# Fix data directory permissions
+sudo chown -R $USER:$USER /var/lib/9router
+chmod 755 /var/lib/9router
+```

+
+```
+Cursor Settings → Models → Advanced:
+  OpenAI API Base URL: https://9router.com/v1
+  OpenAI API Key: [from dashboard]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+**Thay thế:** Self-host trên VPS với domain công khai:
+```bash
+# Deploy to VPS
+git clone https://github.com/decolua/9router.git
+cd 9router/app
+npm install && npm run build
+npm start
+
+# Configure Nginx reverse proxy
+# Point Cursor to: https://your-domain.com/v1
+```
+
+**Công cụ CLI khác hoạt động với localhost:**

+# Combos - Chuỗi Fallback Tùy chỉnh
+
+Tạo các tổ hợp model tùy chỉnh với fallback tự động. Combo cho phép bạn định nghĩa chiến lược routing dựa trên chi phí, chất lượng và tính khả dụng.
+
+---
+
+## Combos là gì?
+
+Combos là **chuỗi fallback tùy chỉnh** bạn tạo trong dashboard. Thay vì dùng một model duy nhất, bạn định nghĩa một chuỗi các model mà 9Router sẽ thử theo thứ tự.
+
+**Ví dụ:**
+```
+Combo name: premium-coding
+Models:
+  1. cc/claude-opus-4-5-20251101 (try first)
+  2. glm/glm-4.7 (if #1 quota exhausted)
+  3. minimax/MiniMax-M2.1 (if #2 quota exhausted)
+```
+
+**Dùng trong CLI:**
+```
+Model: premium-coding
+```
+
+9Router tự động thử từng model theo thứ tự cho đến khi thành công.
+
+---
+
+## Tại sao dùng Combos?
+
+### 1. Tối đa hóa Giá trị Subscription
+```
+cc/claude-opus → glm/glm-4.7 → if/kimi-k2-thinking
+
+→ Use subscription first, cheap backup, free emergency
+→ Get full value from subscriptions you already pay for
+```
+
+### 2. Giảm Chi phí
+```
+glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+
+→ Start with cheapest paid option ($0.60/1M)
+→ Fallback to even cheaper ($0.20/1M)
+→ Emergency free tier
+→ Total cost: ~$5-10/month vs $2000 on ChatGPT API
+```
+
+### 3. Đảm bảo Khả dụng 24/7
+```
+cc/claude-opus → cx/gpt-5.2-codex → glm/glm-4.7 → if/kimi-k2-thinking
+
+→ Always include free tier at the end
+→ Never run out of quota
+→ Code anytime, anywhere
+```
+
+### 4. Tối ưu Chất lượng
+```
+cc/claude-opus-4-5 → cx/gpt-5.2-codex → gc/gemini-3-pro
+
+→ Best models first
+→ Fallback to other premium models
+→ Maintain high quality across fallback chain
+```
+
+---
+
+## Cách tạo Combos
+
+### Bước 1: Mở Dashboard
+
+```
+http://localhost:20128
+→ Login with your password
+```
+
+### Bước 2: Đi đến Combos
+
+```
+Dashboard → Combos → Create New Combo
+```
+
+### Bước 3: Cấu hình Combo
+
+**Tên Combo:**
+```
+premium-coding
+```
+
+**Mô tả (tùy chọn):**
+```
+Subscription first, cheap backup, free emergency
+```
+
+**Chọn Models:**
+```
+1. cc/claude-opus-4-5-20251101
+2. glm/glm-4.7
+3. minimax/MiniMax-M2.1
+```
+
+**Kéo để sắp xếp lại** - Ưu tiên từ trên xuống dưới.
+
+### Bước 4: Lưu
+
+```
+Click "Save Combo"
+→ Combo appears in model list
+```
+

+```
+
+---
+
+## Ví dụ Combos
+
+### Ví dụ 1: Premium Coding (Subscription → Cheap → Free)
+
+**Mục tiêu**: Tối đa giá trị subscription, giảm chi phí thêm.
+
+```
+Dashboard → Combos → Create New
+
+Name: premium-coding
+Models:
+  1. cc/claude-opus-4-5-20251101
+  2. glm/glm-4.7
+  3. minimax/MiniMax-M2.1
+```
+
+**Sử dụng:**
+```
+Cursor IDE:
+  Model: premium-coding
+```
+
+**Hoạt động:**
+```
+Morning (fresh quota):
+  Request → cc/claude-opus-4-5 ✅
+
+Afternoon (Claude quota out):
+  Request → glm/glm-4.7 ✅ (auto switched)
+
+Evening (GLM quota out):
+  Request → minimax/MiniMax-M2.1 ✅ (auto switched)
+```
+
+**Chi phí hàng tháng (100M tokens):**
+```
+80M via Claude Code: $0 (subscription)
+15M via GLM: $9
+5M via MiniMax: $1
+Total: $10 + your subscription
+```
+
+**Tiết kiệm**: ~99% so với ChatGPT API ($2000).
+
+---
+
+### Ví dụ 2: Budget Combo (Cheap → Free)
+
+**Mục tiêu**: Giảm chi phí, dùng free tier làm backup.
+
+```
+Dashboard → Combos → Create New
+
+Name: budget-combo
+Models:
+  1. glm/glm-4.7
+  2. minimax/MiniMax-M2.1

+  Model: budget-combo
+```
+
+**Hoạt động:**
+```
+Request → glm/glm-4.7
+  ✅ Daily quota available → Use GLM ($0.60/1M)
+  ❌ Quota exhausted → Try MiniMax ($0.20/1M)
+  ❌ MiniMax quota out → Use iFlow (FREE)
+```
+
+**Chi phí hàng tháng (100M tokens):**
+```
+70M via GLM: $42
+20M via MiniMax: $4
+10M via iFlow: $0
+Total: $46 vs $2000 on ChatGPT API
+```
+
+**Tiết kiệm**: 97%.
+
+---
+
+### Ví dụ 3: Free Combo (Chi phí 0)
+
+**Mục tiêu**: 100% miễn phí, không bao giờ tốn tiền.
+
+```
+Dashboard → Combos → Create New
+
+Name: free-combo
+Models:
+  1. if/kimi-k2-thinking
+  2. qw/qwen3-coder-plus
+  3. kr/claude-sonnet-4.5
+```
+
+**Sử dụng:**
+```
+Claude Desktop:

+
+**Chi phí hàng tháng:**
+```
+100M tokens via free providers: $0
+Total: $0 forever
+```
+
+**Use case**: Dự án cá nhân, học tập, thử nghiệm.
+
+---
+
+### Ví dụ 4: Quality First (Chỉ Premium Models)
+
+**Mục tiêu**: Chất lượng tốt nhất, không fallback rẻ.
+
+```
+Dashboard → Combos → Create New
+
+Name: quality-first
+Models:
+  1. cc/claude-opus-4-5-20251101
+  2. cx/gpt-5.2-codex
+  3. gc/gemini-3-pro-preview
+```
+
+**Sử dụng:**
+```
+Codex CLI:
+  export OPENAI_BASE_URL="http://localhost:20128"
+  Model: quality-first
+```
+
+**Hoạt động:**
+```
+Request → cc/claude-opus-4-5
+  ❌ Quota out → cx/gpt-5.2-codex
+  ❌ Quota out → gc/gemini-3-pro-preview
+  ❌ All out → Return error (no cheap fallback)
+```
+
+**Use case**: Code production quan trọng, refactoring phức tạp.
+
+---
+
+### Ví dụ 5: Multi-Subscription (Tối đa hết tất cả)
+
+**Mục tiêu**: Dùng hết subscription trước khi trả thêm tiền.
+
+```
+Dashboard → Combos → Create New
+
+Name: multi-sub
+Models:
+  1. gc/gemini-3-flash-preview (FREE 180K/month)
+  2. cc/claude-opus-4-5-20251101 (Pro subscription)
+  3. cx/gpt-5.2-codex (Plus subscription)
+  4. gh/gpt-5 (Copilot subscription)
+  5. glm/glm-4.7 (Cheap backup)
+  6. if/kimi-k2-thinking (Free emergency)
+```
+
+**Chi phí hàng tháng (200M tokens):**
+```
+50M via Gemini CLI: $0 (free tier)
+80M via Claude Code: $0 (subscription)
+40M via Codex: $0 (subscription)
+20M via Copilot: $0 (subscription)
+8M via GLM: $4.80
+2M via iFlow: $0
+Total: $4.80 + existing subscriptions
+```
+
+**Kết quả**: Dùng 190M tokens từ subscription, chỉ $4.80 phụ.
+
+---
+
+### Ví dụ 6: Tối ưu Reset Quota
+
+**Mục tiêu**: Phân bổ sử dụng dựa trên thời gian reset.
+
+```
+Dashboard → Combos → Create New
+
+Name: reset-optimized
+Models:
+  1. cc/claude-opus-4-5 (5h reset, use morning)
+  2. gc/gemini-3-flash (1K/day, use afternoon)
+  3. glm/glm-4.7 (daily 10AM reset, use evening)
+  4. minimax/MiniMax-M2.1 (5h rolling, use night)
+  5. if/kimi-k2-thinking (unlimited, emergency)
+```
+
+**Lịch trình hàng ngày:**
+```
+08:00 - 13:00: Claude Code (fresh 5h quota)
+13:00 - 18:00: Gemini CLI (1K/day quota)
+18:00 - 22:00: GLM (resets 10AM next day)
+22:00 - 08:00: MiniMax (5h rolling) or iFlow
+```
+
+**Kết quả**: Code 24/7 với chi phí tối thiểu.
+
+---
+
+## Dùng Combos trong CLI Tools
+
+### Cursor IDE
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [from dashboard]
+  Model: premium-coding
+```
+
+### Claude Desktop
+
+Sửa `~/.claude/config.json`:
+```json

+  "anthropic_api_key": "your-9router-api-key",
+  "model": "budget-combo"
+}
+```
+
+### Codex CLI

+```
+
+### Cline / Continue / RooCode
+
+```
+Provider: OpenAI Compatible
+Base URL: http://localhost:20128/v1
+API Key: [from dashboard]
+Model: free-combo
+```
+
+### API Request
+
+```bash
+curl http://localhost:20128/v1/chat/completions \
+  -H "Authorization: Bearer your-api-key" \
+  -H "Content-Type: application/json" \

+    "messages": [
+      {"role": "user", "content": "Write a function to..."}
+    ],
+    "stream": true
+  }'
+```
+
+---
+
+## Best Practices
+
+### 1. Luôn bao gồm Free Tier
+
+```
+✅ Good:
+cc/claude-opus → glm/glm-4.7 → if/kimi-k2-thinking
+
+❌ Bad:
+cc/claude-opus → glm/glm-4.7
+(no free fallback, can run out of quota)
+```
+
+**Lý do**: Đảm bảo khả dụng 24/7, không bao giờ bị chặn bởi quota.
+
+### 2. Sắp xếp theo Chi phí (Rẻ đến Đắt)
+
+```
+✅ Good:
+glm/glm-4.7 → minimax/MiniMax-M2.1 → cc/claude-opus
+
+❌ Bad:
+cc/claude-opus → glm/glm-4.7
+(wastes subscription quota on simple tasks)
+```
+
+**Ngoại lệ**: Nếu muốn tối đa giá trị subscription, đặt subscription đầu tiên.
+
+### 3. Phù hợp với Yêu cầu Chất lượng
+
+```
+For production code:
+cc/claude-opus → cx/gpt-5.2-codex → glm/glm-4.7
+
+For quick tasks:
+glm/glm-4.7 → if/kimi-k2-thinking
+
+For experimentation:
+if/kimi-k2-thinking → qw/qwen3-coder-plus
+```
+
+### 4. Cân nhắc Thời gian Reset Quota
+
+```
+Morning combo (fresh quotas):
+cc/claude-opus → cx/gpt-5.2-codex
+
+Evening combo (quotas likely exhausted):
+glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+```
+
+### 5. Tạo nhiều Combo cho các Use Case khác nhau
+
+```
+premium-coding: For complex tasks
+budget-combo: For simple tasks
+free-combo: For experimentation
+quality-first: For production code
+```
+
+**Chuyển đổi combo** dựa trên yêu cầu task.
+
+### 6. Theo dõi hiệu năng Combo
+
+```
+Dashboard → Analytics → Combo Usage:
+  premium-coding:
+    80% via cc/claude-opus (good, using subscription)
+    15% via glm/glm-4.7 (acceptable backup)
+    5% via minimax (rare fallback)
+```
+
+**Tối ưu**: Nếu fallback quá nhiều, tăng quota chính hoặc sắp xếp lại model.
+
+---
+
+## Cấu hình Nâng cao
+
+### Đặt Giới hạn Ngân sách cho mỗi Combo
+
+```
+Dashboard → Combos → Edit → Budget:
+  Daily limit: $5
+  Monthly limit: $50
+```
+
+Khi đạt giới hạn, 9Router bỏ qua model trả phí và chỉ dùng free tier.
+
+### Bật/Tắt Model trong Combo
+
+```
+Dashboard → Combos → Edit → Models:
+  ✅ cc/claude-opus-4-5 (enabled)
+  ❌ glm/glm-4.7 (temporarily disabled)
+  ✅ if/kimi-k2-thinking (enabled)
+```
+
+**Use case**: Tạm tắt model đắt mà không cần xóa combo.
+
+### Clone Combo có sẵn
+
+```
+Dashboard → Combos → Clone "premium-coding"
+→ Creates copy with "-copy" suffix
+→ Modify and save as new combo
+```
+
+**Use case**: Tạo biến thể cho các kịch bản khác nhau.
+
+---
+
+## Troubleshooting
+
+**Issue: Combo không xuất hiện trong danh sách model**
+
+**Giải pháp:**
+1. Refresh dashboard
+2. Kiểm tra combo đã được lưu (dấu tick xanh)
+3. Khởi động lại CLI tool để refresh danh sách model
+
+**Issue: Combo luôn dùng model cuối cùng (free tier)**
+
+**Giải pháp:**
+1. Kiểm tra quota cho các model chính (Dashboard → Quota)
+2. Xác minh API keys hợp lệ (Dashboard → Providers)
+3. Kiểm tra giới hạn ngân sách không vượt quá
+
+**Issue: Combo tốn hơn dự kiến**
+
+**Giải pháp:**
+1. Dashboard → Analytics → Xem usage combo
+2. Kiểm tra model chính có bị hết quota không
+3. Sắp xếp lại model (đặt rẻ hơn lên trước)
+4. Đặt giới hạn ngân sách

+   2.5h remaining (resets in 1h 30m)
+   
+⚠️ GLM-4.7 quota 90% used
+   1M tokens remaining (resets in 5h)
+   
+✅ Gemini CLI quota reset
+   1,000 requests available (daily limit)
+```
+
+### Cảnh báo Ngân sách
+
+```
+Dashboard → Settings → Budget Alerts
+
+Daily budget: $5
+  ✅ Alert at 80% ($4)
+  ✅ Alert at 100% ($5)
+  ✅ Auto-switch to free tier when exceeded
+
+Monthly budget: $150
+  ✅ Alert at 50% ($75)
+  ✅ Alert at 80% ($120)
+  ✅ Alert at 100% ($150)
+```
+
+**Ví dụ thông báo:**
+```
+⚠️ Daily budget 80% used
+   $4.00 / $5.00 spent today
+   
+⚠️ Monthly budget 50% reached
+   $75 / $150 spent this month
+   Projected: $135 (within budget)
+   
+🚨 Daily budget exceeded
+   $5.20 / $5.00 spent today
+   Auto-switched to free tier
+```
+
+### Phát hiện Bất thường Chi phí
+
+```
+Dashboard → Settings → Anomaly Detection
+
+✅ Detect unusual spending patterns
+✅ Alert on cost spikes (>2× daily average)
+✅ Warn on quota exhaustion patterns
+
+Example alert:
+⚠️ Cost spike detected
+   Today: $12.50 (2.5× daily average)
+   Reason: High GLM-4.7 usage (20M tokens)
+   Suggestion: Check if primary models quota-exhausted
+```
+
+---
+
+## Best Practices
+
+### 1. Theo dõi Quota Hàng ngày
+
+```
+Daily routine:
+1. Check dashboard quota overview (30 seconds)
+2. Review reset times
+3. Plan usage around quota availability
+```
+
+**Ví dụ:**
+```
+Morning check:
+  ✅ Claude Code: 5h available (fresh reset)
+  ✅ Gemini CLI: 1K requests available
+  ⚠️ GLM-4.7: 2M tokens left (resets 10AM)
+  
+Action: Use Claude Code for morning work
+```
+
+### 2. Đặt Giới hạn Ngân sách
+
+```
+Dashboard → Settings → Budget:
+  Daily: $5 (prevents overspending)
+  Monthly: $150 (aligns with budget)
+```
+
+**Kết quả**: Auto-switch sang free tier khi đạt giới hạn.
+
+### 3. Tối ưu Combo Usage
+
+```
+Dashboard → Analytics → Combos:
+  Review which models are used most
+  Adjust combo order to minimize costs
+```
+
+**Ví dụ:**
+```
+Current: cc/claude-opus → glm/glm-4.7
+  80% via Claude (good)
+  20% via GLM ($12/month)
+
+Optimized: gc/gemini-3-flash → cc/claude-opus → glm/glm-4.7
+  50% via Gemini (free)
+  40% via Claude (subscription)
+  10% via GLM ($6/month)
+  
+Savings: $6/month
+```
+
+### 4. Theo dõi Thời gian Reset
+
+```
+Dashboard → Quota → Reset Schedule:
+  Claude Code: 5h rolling + Weekly Monday
+  Gemini CLI: Daily 00:00 UTC + Monthly 1st
+  GLM-4.7: Daily 10:00 AM Beijing Time
+  MiniMax: Rolling 5h window
+```
+
+**Chiến lược**: Dùng provider khi quota mới reset.
+
+### 5. Xem Báo cáo Hàng tháng
+
+```
+Dashboard → Analytics → Monthly Report:
+  Total tokens: 1.5B
+  Total cost: $120
+  Savings: 97% vs ChatGPT API
+  
+Insights:
+  - 60% usage via subscriptions ($0)
+  - 30% via GLM ($90)
+  - 10% via free tier ($0)
+  
+Optimization:
+  - Increase Gemini CLI usage (free)
+  - Reduce GLM usage (expensive)
+```

+# Smart Routing & Auto Fallback
+
+9Router tự động định tuyến request qua provider tốt nhất hiện có bằng hệ thống fallback 3 tầng. Không bao giờ ngừng code vì giới hạn quota hay rate limiting.
+
+---
+
+## Cách hoạt động
+
+9Router dùng định tuyến thông minh để tối đa hóa subscription hiện có, giảm chi phí và đảm bảo khả dụng 24/7:
+
+```
+Request → 9Router → Check Tier 1 (Subscription)
+                     ↓ quota exhausted
+                     Check Tier 2 (Cheap)
+                     ↓ budget limit
+                     Check Tier 3 (Free)
+                     ↓
+                     Response
+```
+
+### Hệ thống Fallback 3 tầng
+
+**Tier 1: SUBSCRIPTION (Chính)**
+- Claude Code (Pro/Max)
+- OpenAI Codex (Plus/Pro)
+- Gemini CLI (MIỄN PHÍ 180K/tháng)
+- GitHub Copilot
+- Antigravity (Google)
+
+**Mục tiêu**: Tối đa giá trị từ subscription đã trả tiền.
+
+**Tier 2: CHEAP (Backup)**
+- GLM-4.7 ($0.60/1M input)
+- MiniMax M2.1 ($0.20/1M input)
+- Kimi K2 ($9/tháng cố định)
+
+**Mục tiêu**: Backup siêu rẻ khi hết quota subscription (~90% rẻ hơn ChatGPT API).
+
+**Tier 3: FREE (Khẩn cấp)**
+- iFlow (8 models)
+- Qwen (3 models)
+- Kiro (Claude MIỄN PHÍ)
+
+**Mục tiêu**: Fallback chi phí 0 để code không giới hạn.
+
+---
+
+## Chuyển đổi Tự động
+
+9Router giám sát quota thời gian thực và chuyển provider tự động:
+
+### Kịch bản 1: Hết Quota Subscription
+
+```
+User request → cc/claude-opus-4-5
+               ↓ quota exhausted (5-hour limit reached)
+               Auto switch → glm/glm-4.7
+               ↓ daily quota exhausted
+               Auto switch → minimax/MiniMax-M2.1
+               ↓ 5-hour quota exhausted
+               Auto switch → if/kimi-k2-thinking (FREE)
+               ↓
+               Response delivered ✅
+```
+
+**Kết quả**: Zero downtime, trải nghiệm liền mạch.
+
+### Kịch bản 2: Rate Limiting
+
+```
+User request → cx/gpt-5.2-codex
+               ↓ rate limited (too many requests)
+               Auto switch → glm/glm-4.7
+               ↓
+               Response delivered ✅
+```
+
+### Kịch bản 3: Provider không khả dụng
+
+```
+User request → cc/claude-opus-4-5
+               ↓ provider error (503)
+               Auto switch → next available model
+               ↓
+               Response delivered ✅
+```
+
+---
+
+## Logic chọn Model
+
+9Router chọn model tốt nhất dựa trên:
+
+1. **Khả dụng quota** - Kiểm tra provider còn quota không
+2. **Tier chi phí** - Ưu tiên subscription → cheap → free
+3. **Thời gian reset** - Cân nhắc khi quota reset
+4. **Sức khỏe provider** - Bỏ qua provider có lỗi
+
+### Ví dụ Thứ tự Ưu tiên
+
+Cho request đến `cc/claude-opus-4-5`:
+
+```
+1. Check Claude Code quota
+   ✅ Available → Use cc/claude-opus-4-5
+   ❌ Exhausted → Continue to step 2
+
+2. Check fallback tier (if configured)
+   ✅ GLM quota available → Use glm/glm-4.7
+   ❌ Exhausted → Continue to step 3
+
+3. Check free tier
+   ✅ iFlow available → Use if/kimi-k2-thinking
+   ❌ All exhausted → Return quota error
+```
+
+---
+
+## Tùy chọn Cấu hình
+
+### Cài đặt Dashboard
+
+**1. Bật/Tắt Auto Fallback**
+
+```
+Dashboard → Settings → Smart Routing
+→ Toggle "Auto Fallback" ON/OFF
+```
+
+- **ON** (mặc định): Chuyển tier tự động
+- **OFF**: Strict mode, trả lỗi nếu model chính không khả dụng
+
+**2. Đặt Giới hạn Ngân sách**
+
+```
+Dashboard → Settings → Budget Control
+→ Daily limit: $5
+→ Monthly limit: $50
+```
+
+Khi đạt ngân sách, 9Router tự động chuyển sang free tier.
+
+**3. Cấu hình Thứ tự Fallback**
+
+```
+Dashboard → Settings → Fallback Priority
+→ Drag to reorder providers within each tier
+```
+
+Ví dụ thứ tự tùy chỉnh:
+```
+Tier 1: Gemini CLI → Claude Code → Codex
+Tier 2: MiniMax → GLM → Kimi
+Tier 3: iFlow → Kiro → Qwen
+```
+
+**4. Thông báo Reset Quota**
+
+```
+Dashboard → Settings → Notifications
+→ Email when quota resets
+→ Alert when 80% quota used
+```
+
+---
+
+## Ví dụ
+
+### Ví dụ 1: Auto Fallback Cơ bản
+
+**Setup:**
+```
+Model: cc/claude-opus-4-5-20251101
+Fallback: Auto (default 3-tier)
+```
+
+**Hoạt động:**
+```
+Morning (fresh quota):
+  Request → cc/claude-opus-4-5 ✅
+
+Afternoon (quota exhausted):
+  Request → glm/glm-4.7 ✅ (auto switched)
+
+Evening (GLM quota out):
+  Request → minimax/MiniMax-M2.1 ✅ (auto switched)
+
+Late night (all paid quota out):
+  Request → if/kimi-k2-thinking ✅ (free tier)
+```
+
+**Chi phí**: ~$5-10/tháng extra (chủ yếu được bao bởi subscription).
+
+### Ví dụ 2: Định tuyến theo Ngân sách
+
+**Setup:**
+```
+Dashboard → Settings:
+  Daily budget: $2
+  Monthly budget: $20
+  Fallback: Enabled
+```
+
+**Hoạt động:**
+```
+Day 1-15 (within budget):
+  Requests → glm/glm-4.7 (cheap tier)
+  Cost: $1.50/day
+
+Day 16 (budget reached):
+  Requests → if/kimi-k2-thinking (free tier)
+  Cost: $0
+
+Next month (budget resets):
+  Requests → glm/glm-4.7 again
+```
+
+**Kết quả**: Không bao giờ vượt $20/tháng, luôn khả dụng.
+
+### Ví dụ 3: Chế độ Chỉ Subscription
+
+**Setup:**
+```
+Dashboard → Settings:
+  Auto Fallback: OFF
+  Strict mode: ON
+```
+
+**Hoạt động:**
+```
+Request → cc/claude-opus-4-5
+  ✅ Quota available → Success
+  ❌ Quota exhausted → Return error (no fallback)
+```
+
+**Use case**: Khi chỉ muốn dùng subscription trả phí, không phí thêm.
+
+### Ví dụ 4: Chế độ Chỉ Free
+
+**Setup:**
+```
+Model: if/kimi-k2-thinking
+Fallback: qw/qwen3-coder-plus → kr/claude-sonnet-4.5
+```
+
+**Hoạt động:**
+```
+All requests → Free tier only
+Cost: $0 forever
+```
+
+**Use case**: Dự án cá nhân, học tập, thử nghiệm.
+
+---
+
+## Best Practices
+
+### 1. Tối đa Giá trị Subscription
+
+```
+Strategy:
+- Set subscription models as Tier 1
+- Monitor quota usage in dashboard
+- Use cheap tier only when subscription exhausted
+```
+
+**Ví dụ combo:**
+```
+cc/claude-opus-4-5 → glm/glm-4.7 → if/kimi-k2-thinking
+```
+
+### 2. Tối ưu Chi phí
+
+```
+Strategy:
+- Use Gemini CLI free tier first (180K/month)
+- Fallback to GLM/MiniMax (ultra-cheap)
+- Emergency: iFlow (free)
+```
+
+**Ví dụ combo:**
+```
+gc/gemini-3-flash-preview → glm/glm-4.7 → if/kimi-k2-thinking
+```
+
+### 3. Tối ưu Chất lượng
+
+```
+Strategy:
+- Use best models (Claude Opus, GPT-5.2)
+- Fallback to good cheap models (GLM-4.7)
+- Last resort: Free tier
+```
+
+**Ví dụ combo:**
+```
+cc/claude-opus-4-5 → cx/gpt-5.2-codex → glm/glm-4.7
+```
+
+### 4. Khả dụng 24/7
+
+```
+Strategy:
+- Always include free tier in fallback
+- Monitor quota reset times
+- Distribute usage across providers
+```
+
+**Ví dụ combo:**
+```
+cc/claude-opus-4-5 → glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+```
+
+**Kết quả**: Không bao giờ hết quota, code mọi lúc.
+
+---
+
+## Chiến lược Reset Quota
+
+Lên kế hoạch usage quanh thời gian reset quota:
+
+| Provider | Quota Reset | Chiến lược |
+|----------|-------------|----------|
+| **Claude Code** | 5 giờ + hàng tuần | Dùng buổi sáng, quota mới |
+| **Codex** | 5 giờ + hàng tuần | Dùng sau khi hết quota Claude |
+| **Gemini CLI** | Hàng ngày (1K) + Hàng tháng (180K) | Dùng cả ngày |
+| **GLM-4.7** | Hàng ngày 10:00 AM | Dùng buổi tối, reset sáng hôm sau |
+| **MiniMax M2.1** | 5 giờ rolling | Dùng mọi lúc, theo rolling window |
+| **iFlow/Qwen/Kiro** | Không giới hạn | Backup khẩn cấp |
+
+**Ví dụ lịch hàng ngày:**
+```
+08:00 - 13:00: Claude Code (fresh 5h quota)
+13:00 - 18:00: Gemini CLI (1K/day quota)
+18:00 - 22:00: GLM-4.7 (cheap, resets 10AM)
+22:00 - 08:00: MiniMax or iFlow (5h rolling or free)
+```
+
+---
+
+## Giám sát & Cảnh báo
+
+### Dashboard Quota Tracker
+
+```
+Dashboard → Quota Overview:
+  Claude Code: 2.5h / 5h remaining (50%)
+  Gemini CLI: 450 / 1000 requests today
+  GLM-4.7: 5M / 10M tokens (resets in 8h)
+  MiniMax: 3M / 5M tokens (rolling 5h)
+```
+
+### Thông báo Thời gian thực
+
+```
+Dashboard → Notifications:
+  ⚠️ Claude Code quota 80% used (1h remaining)
+  ✅ GLM-4.7 quota reset (10M tokens available)
+  💰 Daily budget 50% used ($2.50 / $5)
+```
+
+### Usage Analytics
+
+```
+Dashboard → Analytics:
+  Today: 50M tokens
+    - 30M via Claude Code (subscription)
+    - 15M via GLM-4.7 ($9)
+    - 5M via iFlow (free)
+  
+  Cost: $9 (vs $1000 on ChatGPT API)
+  Savings: 99%
+```
+
+---
+
+## Troubleshooting
+
+**Issue: "All providers quota exhausted"**
+
+**Giải pháp:**
+1. Kiểm tra quota tracker trong dashboard
+2. Đợi quota reset (xem countdown)
+3. Thêm free tier vào fallback chain
+4. Hoặc tăng giới hạn ngân sách
+
+**Issue: "Too many fallback switches"**
+
+**Giải pháp:**
+1. Kiểm tra provider chính có down không
+2. Tăng giới hạn quota (upgrade subscription)
+3. Dùng model chính rẻ hơn (GLM thay vì Claude)
+
+**Issue: "Unexpected costs"**
+
+**Giải pháp:**
+1. Dashboard → Analytics → Xem usage
+2. Đặt giới hạn ngân sách hàng ngày/tháng
+3. Chuyển sang free tier cho task không quan trọng
+4. Dùng combo với free fallback

+# Storage
+export DATA_DIR="~/.9router"
+
+# Server
+export PORT="20128"
+export NODE_ENV="production"
+
+# Logging
+export ENABLE_REQUEST_LOGS="false"
+```
+
+### Data Directory
+
+**Vị trí mặc định:** `~/.9router`
+
+**Nội dung:**
+```
+~/.9router/
+  ├── db.json           # Database (providers, combos, usage)
+  ├── api-keys.json     # API keys
+  └── logs/             # Request logs (if enabled)
+```
+
+**Đổi vị trí:**
+
+```bash
+export DATA_DIR="/custom/path"
+9router
+```
+
+### Cấu hình Port
+
+**Port mặc định:** `20128`
+
+**Đổi port:**
+
+```bash
+export PORT="3000"
+9router
+```
+
+**Hoặc dùng command line:**
+
+```bash
+9router --port 3000
+```
+
+---
+
+## Troubleshooting
+
+### Port đã được dùng
+
+**Lỗi:**
+```
+Error: listen EADDRINUSE: address already in use :::20128
+```
+
+**Giải pháp 1: Kill process hiện có**
+
+```bash
+# Find process using port 20128
+lsof -i :20128
+
+# Kill process
+kill -9 <PID>
+```
+
+**Giải pháp 2: Dùng port khác**
+
+```bash
+9router --port 3000
+```
+
+### Permission Denied
+
+**Lỗi:**
+```
+Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/9router'
+```
+
+**Giải pháp: Dùng sudo (không khuyến nghị) hoặc fix npm permissions**
+
+```bash
+# Fix npm permissions (recommended)
+mkdir ~/.npm-global
+npm config set prefix '~/.npm-global'
+echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
+source ~/.bashrc
+
+# Then install again
+npm install -g 9router
+```
+
+### Node.js Phiên bản quá cũ
+
+**Lỗi:**
+```
+Error: The engine "node" is incompatible with this module
+```
+
+**Giải pháp: Cập nhật Node.js**
+
+```bash
+# Using nvm (recommended)
+nvm install 20
+nvm use 20
+
+# Or download from nodejs.org
+```
+
+### Dashboard không mở
+
+**Vấn đề:** Dashboard không tự mở
+
+**Giải pháp 1: Mở thủ công**
+
+```
+http://localhost:20128
+```
+
+**Giải pháp 2: Kiểm tra firewall**
+
+```bash
+# macOS: Allow Node.js in System Preferences → Security
+# Linux: Check iptables
+# Windows: Check Windows Firewall
+```
+
+### Không kết nối được Provider
+
+**Vấn đề:** OAuth login thất bại hoặc API key không hợp lệ
+
+**Giải pháp 1: Kiểm tra kết nối internet**
+
+```bash
+ping google.com
+```
+
+**Giải pháp 2: Kiểm tra trạng thái provider**
+
+- Claude Code: [status.anthropic.com](https://status.anthropic.com)
+- OpenAI: [status.openai.com](https://status.openai.com)
+- Gemini: [status.cloud.google.com](https://status.cloud.google.com)
+
+**Giải pháp 3: Tạo lại API key**
+
+```
+Dashboard → Provider → Disconnect → Reconnect
+```
+
+### Sử dụng RAM cao
+
+**Vấn đề:** 9Router dùng quá nhiều RAM
+
+**Giải pháp: Khởi động lại server**
+
+```bash
+# Stop
+pkill -f 9router
+
+# Start
+9router
+```
+
+**Hoặc dùng PM2 để auto-restart:**
+
+```bash
+npm install -g pm2
+pm2 start 9router --name 9router
+pm2 save
+```
+
+---

+# Bắt đầu
+
+Khởi chạy 9Router trong 5 phút và bắt đầu định tuyến các request AI một cách thông minh.
+
+---
+
+## Bắt đầu nhanh
+
+### 1. Cài đặt
+
+```bash
+npm install -g 9router
+```
+
+**Yêu cầu:** Node.js 20+ ([Chi tiết cài đặt](getting-started/installation.md))
+
+### 2. Khởi chạy
+
+```bash
+9router
+```
+
+🎉 **Dashboard tự động mở** tại `http://localhost:20128`
+
+- Mật khẩu mặc định: `123456` (đổi trong dashboard)
+- API key được tạo tự động
+- Sẵn sàng kết nối provider
+
+### 3. Kết nối Provider
+
+Bạn có 3 cách để kết nối provider:
+
+#### Cách A: OAuth (Subscription Provider)
+
+**Tốt nhất cho:** Claude Code, Codex, Gemini CLI, GitHub Copilot
+
+```
+Dashboard → Providers → Connect [Provider]
+→ OAuth login → Auto token refresh
+→ Quota tracking enabled
+```
+
+**Ví dụ: Claude Code**
+1. Click "Connect Claude Code"
+2. Đăng nhập tài khoản Claude
+3. Cho phép 9Router
+4. ✅ Xong! Dùng model: `cc/claude-opus-4-5-20251101`
+
+#### Cách B: API Key (Cheap Provider)
+
+**Tốt nhất cho:** GLM, MiniMax, Kimi, OpenRouter
+
+```
+Dashboard → Providers → Add API Key
+→ Select provider
+→ Paste API key
+→ Save
+```
+
+**Ví dụ: GLM-4.7**
+1. Đăng ký tại [Zhipu AI](https://open.bigmodel.cn/)
+2. Lấy API key từ Coding Plan
+3. Dashboard → Add API Key → Provider: `glm` → Paste key
+4. ✅ Xong! Dùng model: `glm/glm-4.7`
+
+#### Cách C: Free Provider (Miễn phí)
+
+**Tốt nhất cho:** iFlow, Qwen, Kiro
+
+```
+Dashboard → Providers → Connect [Free Provider]
+→ Device code or OAuth
+→ Unlimited usage
+```
+
+**Ví dụ: iFlow**
+1. Click "Connect iFlow"
+2. Đăng nhập tài khoản iFlow
+3. Cho phép
+4. ✅ Xong! Dùng 8 model: `if/kimi-k2-thinking`, `if/qwen3-coder-plus`, v.v.
+
+---
+
+## 4. Dùng trong CLI Tools
+
+Trỏ công cụ code của bạn tới 9Router:
+
+### Cursor IDE
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [from 9router dashboard]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+### Claude Desktop
+
+Sửa `~/.claude/config.json`:
+
+```json
+{
+  "anthropic_api_base": "http://localhost:20128/v1",
+  "anthropic_api_key": "your-9router-api-key"
+}
+```
+
+### Cline / Continue / RooCode
+
+```
+Provider: OpenAI Compatible
+Base URL: http://localhost:20128/v1
+API Key: [from dashboard]
+Model: cc/claude-opus-4-5-20251101
+```
+
+### Codex CLI
+
+```bash
+export OPENAI_BASE_URL="http://localhost:20128"
+export OPENAI_API_KEY="your-9router-api-key"
+
+codex "your prompt"
+```
+
+---
+
+## 5. Tạo Smart Combos (Tùy chọn)
+
+Combo cho phép fallback tự động giữa các model:
+
+```
+Dashboard → Combos → Create New
+
+Name: premium-coding
+Models:
+  1. cc/claude-opus-4-5-20251101 (Subscription primary)
+  2. glm/glm-4.7 (Cheap backup, $0.6/1M)
+  3. if/kimi-k2-thinking (Free fallback)
+
+Use in CLI: premium-coding
+```
+
+**Cách hoạt động:**
+1. Thử Claude Opus trước (subscription của bạn)
+2. Nếu hết quota → GLM-4.7 (siêu rẻ)
+3. Nếu hết budget → iFlow (miễn phí)
+4. Zero downtime, chuyển đổi tự động!
+
+---
+
+## Model có sẵn
+
+### Subscription Models (Dùng đầu tiên)

+- `kr/claude-sonnet-4.5` - Claude Sonnet 4.5
+- `kr/claude-haiku-4.5` - Claude Haiku 4.5
+
+---
+
+## Chiến lược Tối ưu Chi phí
+
+### Ngân sách hàng tháng: $10-20/tháng
+
+```
+1. Use Gemini CLI free tier (180K/month) for quick tasks
+2. Use Claude Code subscription quota fully (you already pay)
+3. Fallback to GLM ($0.6/1M) when quota out
+4. Emergency: MiniMax M2.1 ($0.20/1M) or iFlow (free)
+
+Real example (100M tokens/month):
+  60M via Gemini CLI: $0 (free tier)
+  30M via Claude Code: $0 (subscription you already have)
+  8M via GLM: $4.80
+  2M via MiniMax: $0.40
+  Total: $5.20/month + existing subscriptions
+```
+
+### Chiến lược Reset Quota
+
+```
+Daily routine:
+1. Morning: Fresh Claude Code quota (5h reset)
+2. Afternoon: Switch to Gemini CLI (1K/day)
+3. Evening: GLM daily quota (reset 10AM next day)
+4. Late night: MiniMax (5h rolling) or iFlow (free)
+
+→ Code 24/7 with minimal extra cost!

+# Chào mừng đến với 9Router
+
+**Dùng Claude, Codex, Gemini MIỄN PHÍ • Lựa chọn siêu rẻ từ $0.20/1M tokens**
+
+9Router là bộ định tuyến mô hình AI giúp tối đa hóa giá trị subscription và giảm chi phí thông qua định tuyến thông minh và fallback tự động.
+
+---
+
+## 9Router là gì?
+
+9Router là một proxy thông minh nằm giữa các công cụ lập trình của bạn (Cursor, Cline, Claude Desktop) và các nhà cung cấp AI. Nó tự động định tuyến request đến model tốt nhất hiện có dựa trên quota, chi phí và tính khả dụng.
+
+**Đừng lãng phí tiền:**
+- ❌ Quota subscription hết hạn mỗi tháng mà không dùng đến
+- ❌ Rate limit chặn bạn đang lập trình
+- ❌ API đắt đỏ ($20-50/tháng cho mỗi provider)
+- ❌ Chuyển đổi provider thủ công
+
+**Bắt đầu tối đa hóa giá trị:**
+- ✅ **Tối đa Subscription** - Theo dõi và dùng từng chút quota của Claude Code, Codex, Gemini
+- ✅ **MIỄN PHÍ** - Truy cập model iFlow, Qwen, Kiro qua CLI
+- ✅ **Backup siêu rẻ** - GLM ($0.6/1M), MiniMax M2.1 ($0.20/1M)
+- ✅ **Smart Fallback** - Subscription → Cheap → Free, chuyển đổi tự động
+
+---
+
+## Tính năng chính
+
+### 🔄 Smart 3-Tier Fallback
+
+```
+Setup once, never stop coding:
+
+Tier 1 (SUBSCRIPTION): Claude Code → Codex → Gemini
+  ↓ quota exhausted
+Tier 2 (CHEAP): GLM-4.7 → MiniMax M2.1 → Kimi
+  ↓ budget limit
+Tier 3 (FREE): iFlow → Qwen → Kiro
+
+→ Automatic switching, zero downtime!
+```
+
+### 📊 Theo dõi Quota
+
+- Tiêu thụ token thời gian thực cho mỗi provider
+- Đếm ngược reset (5 giờ, hàng ngày, hàng tuần, hàng tháng)
+- Ước tính chi phí cho tier trả phí
+- Báo cáo chi tiêu hàng tháng
+
+### 🎯 Hỗ trợ CLI Toàn diện
+
+Hoạt động với mọi công cụ hỗ trợ custom OpenAI endpoint:
+
+✅ **Cursor** • **Cline** • **Claude Desktop** • **Codex** • **RooCode** • **Continue** • **Bất kỳ tool nào tương thích OpenAI**
+
+### 💰 Tối ưu Chi phí
+
+**Ví dụ thực tế (100M tokens/tháng):**
+```
+60M qua Gemini CLI: $0 (free tier)
+30M qua Claude Code: $0 (subscription đã có)
+8M qua GLM: $4.80
+2M qua MiniMax: $0.40
+Tổng: $5.20/tháng so với $2000 trên ChatGPT API!
+```
+
+---
+
+## Tại sao chọn 9Router?
+
+### Tối đa hóa Subscription
+
+Đã trả tiền cho Claude Code ($20-100/tháng) hoặc Codex ($20-200/tháng)? Nhận giá trị đầy đủ:
+
+- Theo dõi sử dụng quota thời gian thực
+- Tự động chuyển khi quota reset (5 giờ, hàng tuần)
+- Dùng hết mọi token trước khi hết hạn
+- Gemini CLI: 180K completions/tháng **MIỄN PHÍ**
+
+### Backup Siêu Rẻ
+
+Khi quota subscription hết, trả vài xu:
+
+| Provider | Giá per 1M tokens | Reset |
+|----------|-------------------|-------|
+| **GLM-4.7** | $0.60 input / $2.20 output | Hàng ngày 10:00 AM |
+| **MiniMax M2.1** | $0.20 input / $1.00 output | 5 giờ rolling |
+| **Kimi K2** | $9/tháng (10M tokens) | Hàng tháng |
+
+**~90% rẻ hơn ChatGPT API ($20/1M)!**
+
+### Fallback Miễn phí Mãi mãi
+
+Backup khẩn cấp khi mọi thứ khác đều bị giới hạn quota:
+
+- **iFlow**: 8 models (Kimi K2, Qwen3 Coder Plus, GLM 4.7, MiniMax M2)
+- **Qwen**: 3 models (Qwen3 Coder Plus/Flash, Vision)
+- **Kiro**: Claude Sonnet 4.5, Haiku 4.5 (AWS Builder ID)

+
+```bash
+echo $ANTHROPIC_BASE_URL
+```
+
+## Model Aliases
+
+Claude Code hỗ trợ các alias model sau ánh xạ sang model 9Router:
+
+| Alias | Model | Biến môi trường |
+|-------|-------|---------------------|
+| `opus` | Claude Opus 4.5 | `ANTHROPIC_DEFAULT_OPUS_MODEL` |
+| `sonnet` | Claude Sonnet 4.5 | `ANTHROPIC_DEFAULT_SONNET_MODEL` |
+| `haiku` | Claude Haiku 4.5 | `ANTHROPIC_DEFAULT_HAIKU_MODEL` |
+
+## Ví dụ Sử dụng
+
+### Dùng Model Aliases
+
+```bash
+# Use Opus model
+claude --model opus "Explain quantum computing"
+
+# Use Sonnet model
+claude --model sonnet "Write a Python function"
+
+# Use Haiku model
+claude --model haiku "Quick code review"
+```
+
+### Dùng Full Model Names
+
+```bash
+claude --model cc/claude-opus-4-5-20251101 "Your prompt here"
+```
+
+## File Settings
+
+Claude Code lưu cấu hình trong `~/.claude/settings.json`. Bạn có thể sửa file này thủ công nếu cần:
+
+```json
+{
+  "baseUrl": "http://localhost:20128/v1",
+  "defaultModel": "sonnet"
+}
+```
+
+## Troubleshooting
+
+### Lỗi Connection
+
+Nếu gặp lỗi kết nối:
+
+1. Xác minh 9Router đang chạy: `curl http://localhost:20128/health`
+2. Kiểm tra biến môi trường đã set đúng
+3. Đảm bảo không firewall nào chặn port 20128
+
+### Model Not Found
+
+Nếu gặp lỗi "model not found":
+
+1. Xác minh tên model khớp với cấu hình 9Router
+2. Kiểm tra kết nối provider đang hoạt động trong 9Router dashboard
+3. Đảm bảo model có sẵn trong các provider đã kết nối
+
+## Cloud Endpoint
+
+Để dùng 9Router cloud endpoint thay vì localhost:
+
+```bash
+export ANTHROPIC_BASE_URL="https://9router.com"
+```
+
+Đảm bảo bạn đã cấu hình API key trong 9Router cloud dashboard.

+
+## Cấu hình Nâng cao
+
+### Dùng Cloud Endpoint
+
+Để dùng 9Router cloud endpoint thay vì localhost:
+
+1. Trong Cline settings, đặt Base URL: `https://9router.com`
+2. Đảm bảo bạn đã cấu hình API key trong 9Router cloud dashboard
+3. Đảm bảo cloud endpoint đang hoạt động và truy cập được
+
+### Nhiều Model
+
+Bạn có thể chuyển nhanh giữa các model:
+
+1. Mở Cline settings
+2. Đổi field **Model** sang model khác
+3. Lưu và tiếp tục chat với model mới
+
+### Custom Timeout
+
+Nếu gặp vấn đề timeout với request lớn:
+
+1. Mở VSCode settings (Cmd/Ctrl + ,)
+2. Tìm "Cline timeout"
+3. Tăng giá trị timeout (mặc định thường là 30 giây)
+
+## Best Practices
+
+1. **Dùng Model phù hợp**: Chọn model nhanh (như Haiku hoặc Flash) cho task đơn giản, model mạnh hơn (như Opus hoặc GPT-4) cho task phức tạp
+2. **Theo dõi Usage**: Kiểm tra 9Router dashboard để xem thống kê và chi phí
+3. **Quản lý Context**: Giữ cuộc trò chuyện tập trung để giảm token usage
+4. **Chuyển Model**: Chuyển model dựa trên độ phức tạp task để tối ưu chi phí và hiệu năng
+5. **Bảo mật API Key**: Không bao giờ commit API key vào version control
+
+## Tích hợp với Tính năng 9Router
+
+### Định tuyến Model
+
+9Router tự động định tuyến request đến provider tốt nhất hiện có dựa trên:
+- Tính khả dụng của model
+- Trạng thái sức khỏe provider
+- Tối ưu chi phí
+- Load balancing
+
+### Hỗ trợ Fallback
+
+Nếu một provider thất bại, 9Router tự động fallback sang provider khác đã cấu hình trong dashboard.
+
+### Theo dõi Usage
+
+Giám sát usage Cline qua 9Router dashboard:
+- Tổng request
+- Token usage
+- Chi phí mỗi model
+- Phân bổ provider

+- Kiểm tra VSCode Developer Console để xem lỗi: `Help` → `Toggle Developer Tools`
+
+### Chọn sai Model
+- Click dropdown model trong sidebar Continue
+- Chọn đúng model 9Router
+- Tên model phải khớp chính xác (case-sensitive)
+
+### Cấu hình không Load
+- Xác minh JSON syntax hợp lệ (dùng JSON validator)
+- Kiểm tra vị trí file: `~/.continue/config.json`
+- Reload cửa sổ VSCode sau khi thay đổi
+
+### Hiệu năng Chậm
+- Chuyển sang model nhanh hơn (haiku, flash)
+- Giảm context size trong contextProviders
+- Kiểm tra độ trễ network đến 9Router
+
+## Best Practices
+
+### Chiến lược Chọn Model
+- **Edit nhanh**: Dùng `cc/claude-haiku-4-20250514`
+- **Tạo code**: Dùng `cx/deepseek-chat`
+- **Refactoring phức tạp**: Dùng `cc/claude-opus-4-5-20251101`
+- **Giải quyết vấn đề**: Dùng `cx/deepseek-reasoner`
+
+### Quản lý Context
+- Chỉ chọn code liên quan trước khi hỏi
+- Dùng prompt cụ thể, rõ ràng
+- Chia task phức tạp thành các bước nhỏ
+
+### Tối ưu Chi phí
+- Dùng model nhanh hơn/rẻ hơn cho task đơn giản
+- Giới hạn context size khi có thể
+- Cache response thường dùng

+## Sử dụng
+
+### Giao diện Chat
+
+1. Mở Cursor chat (Cmd/Ctrl + L)
+2. Chọn model từ dropdown
+3. Bắt đầu chat với AI qua 9Router
+
+### Tạo Code Inline
+
+1. Chọn code trong editor
+2. Nhấn Cmd/Ctrl + K
+3. Nhập prompt
+4. Cursor sẽ dùng 9Router để tạo code
+
+### Giải thích Code
+
+1. Chọn code trong editor
+2. Nhấn Cmd/Ctrl + L
+3. Hỏi "Explain this code"
+4. Nhận giải thích AI qua 9Router
+
+## Troubleshooting
+
+### Lỗi "Invalid API Key"
+
+1. Xác minh API key trong 9Router dashboard
+2. Đảm bảo bạn sao chép đầy đủ key bao gồm prefix `sk-9router-`
+3. Kiểm tra API key chưa hết hạn
+4. Thử tạo API key mới
+
+### Lỗi "Model Not Found"
+
+1. Xác minh tên model khớp chính xác với cấu hình 9Router
+2. Kiểm tra kết nối provider đang hoạt động trong 9Router dashboard
+3. Đảm bảo model có sẵn trong các provider đã kết nối
+4. Thử dùng tên model đầy đủ (ví dụ: `openai/gpt-4` thay vì `gpt-4`)
+
+### Lỗi Connection
+
+1. Xác minh bạn đang dùng cloud endpoint: `https://9router.com`
+2. Kiểm tra kết nối internet
+3. Đảm bảo dịch vụ 9Router cloud đang hoạt động
+4. Thử tắt VPN hoặc proxy nếu đang bật
+
+### Localhost không hoạt động
+
+> **Nhớ**: Cursor không hỗ trợ endpoint localhost. Bạn phải dùng cloud endpoint `https://9router.com`. Nếu cần dùng 9Router cục bộ, hãy cân nhắc dùng dịch vụ tunneling như ngrok để expose endpoint cục bộ.
+
+## Setup Cloud Endpoint
+
+Nếu bạn chạy 9Router cục bộ và muốn dùng với Cursor:
+
+1. Bật cloud endpoint trong 9Router settings
+2. Cấu hình URL cloud endpoint trong 9Router dashboard
+3. Dùng URL cloud trong Cursor settings
+4. Đảm bảo 9Router instance cục bộ có thể truy cập từ internet
+
+## Best Practices
+
+1. **Dùng Model Aliases**: Tạo alias ngắn cho model thường dùng trong 9Router
+2. **Theo dõi Usage**: Kiểm tra 9Router dashboard để xem thống kê và chi phí
+3. **Xoay API Key**: Định kỳ xoay API key để bảo mật
+4. **Test Model**: Thử các model khác nhau để tìm model tốt nhất cho use case

+## Ví dụ Sử dụng
+
+### Setup Cursor IDE
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [from 9router dashboard]
+  Model: glm/glm-4.7
+```
+
+### Tạo Combo (Khuyên dùng)
+
+```
+Dashboard → Combos → Create New
+
+Name: cheap-backup
+Models:
+  1. cc/claude-opus-4-5 (Subscription primary)
+  2. glm/glm-4.7 (Cheap backup, daily reset)
+  3. minimax/MiniMax-M2.1 (Cheapest fallback)
+  4. if/kimi-k2-thinking (FREE emergency)
+
+Use in CLI: cheap-backup
+```
+
+**Kết quả:** Subscription → Cheap → Cheapest → Free
+
+---
+
+## Tối ưu Chi phí
+
+### Chiến lược 1: Lịch Reset Hàng ngày
+
+```
+Morning (10AM): Fresh GLM quota
+→ Use GLM for heavy tasks
+→ Save subscription quota
+
+Afternoon: Subscription quota
+→ Use Claude/Codex for complex tasks
+
+Evening: MiniMax (5h reset)
+→ Cheap fallback for late work
+
+Night: Free tier (iFlow)
+→ Zero cost emergency backup
+```
+
+### Chiến lược 2: Ưu tiên Ngân sách
+
+```
+Set monthly budget: $20
+
+Allocation:
+- $9 Kimi K2 (10M tokens flat)
+- $6 GLM daily quota (10M tokens)
+- $5 MiniMax overflow (25M tokens)
+
+Total: 45M tokens for $20
+vs 1M tokens for $20 on ChatGPT API!
+```
+
+### Chiến lược 3: Tối đa Subscription Trước
+
+```
+Priority:
+1. Gemini CLI (180K/month FREE)
+2. Claude Code (subscription you already pay)
+3. GLM-4.7 (cheap backup, $0.6/1M)
+4. MiniMax M2.1 (cheapest, $0.2/1M)
+5. iFlow (FREE emergency)
+
+Monthly cost example (100M tokens):
+- 60M via Gemini CLI: $0 (free)
+- 30M via Claude Code: $0 (subscription)
+- 8M via GLM: $4.80
+- 2M via MiniMax: $0.40
+Total: $5.20/month!
+```
+
+---
+
+## Ví dụ Thực tế
+
+### Ví dụ 1: Tháng Coding Nặng (100M tokens)
+
+```
+Breakdown:
+- 60M via subscription (Claude/Codex): $0 extra
+- 30M via GLM-4.7: $18
+- 10M via MiniMax M2.1: $2
+
+Total: $20/month
+vs $2000 on ChatGPT API!
+
+Savings: 99% cheaper!
+```
+
+### Ví dụ 2: Coder Ngân sách ($10/tháng)
+
+```
+Strategy:
+- $9 Kimi K2 (10M tokens)
+- $1 MiniMax overflow (5M tokens)
+
+Total: 15M tokens for $10
+vs 0.5M tokens for $10 on ChatGPT API!
+
+30× more tokens!
+```
+
+### Ví dụ 3: Freelancer (Usage Biến thiên)
+
+```
+Light month (20M tokens):
+- 15M via subscription: $0
+- 5M via GLM: $3
+Total: $3
+
+Heavy month (150M tokens):
+- 60M via subscription: $0
+- 60M via GLM: $36
+- 30M via MiniMax: $6
+Total: $42
+
+Average: $22.50/month
+vs $3400 on ChatGPT API!
+```
+
+---
+
+## Best Practices
+
+### 1. Theo dõi Quota Hàng ngày
+
+```
+Dashboard shows:
+- GLM quota: 75% used (reset in 6h)
+- MiniMax quota: 50% used (reset in 2h)
+- Kimi quota: 8M/10M used (reset in 15 days)
+
+Plan heavy tasks around reset times!
+```
+
+### 2. Dùng Coding Plan (GLM)
+
+```
+Standard: 1× quota
+Coding Plan: 3× quota (same price!)
+
+→ Always choose Coding Plan
+```
+
+### 3. Kết hợp với Free Tier
+
+```
+Combo:
+1. gc/gemini-3-flash (FREE primary)
+2. glm/glm-4.7 (cheap backup)
+3. minimax/MiniMax-M2.1 (cheapest)
+4. if/kimi-k2-thinking (FREE emergency)
+
+Result: Minimize costs, maximize uptime
+```
+
+### 4. Đặt Cảnh báo Ngân sách
+
+```
+Dashboard → Settings → Budget Alerts
+
+Daily: $2 limit
+Weekly: $10 limit
+Monthly: $30 limit
+
+→ Auto switch to free tier when limit reached
+```
+
+---
+
+## Troubleshooting
+
+### "Quota exhausted"
+
+**Giải pháp:**
+- GLM: Đợi đến 10:00 AM giờ Bắc Kinh
+- MiniMax: Đợi 5 giờ kể từ lần dùng đầu
+- Kimi: Đợi đến ngày 1 tháng sau
+- Dùng combo fallback sang free tier
+
+### "API key invalid"
+
+**Giải pháp:**
+- Kiểm tra API key sao chép đúng
+- Xác minh tài khoản có credits
+- Tạo lại API key nếu cần
+
+### "High costs"
+
+**Giải pháp:**
+- Kiểm tra usage stats trong Dashboard
+- Đặt cảnh báo ngân sách
+- Chuyển sang MiniMax ($0.2/1M rẻ nhất)
+- Dùng free tier cho task không quan trọng
+
+---
+
+## Bước tiếp theo
+
+- **Thêm free fallback:** [Free Providers](./free.md)
+- **Setup subscriptions:** [Subscription Providers](./subscription.md)
+- **Tạo combos:** Dashboard → Combos → Create New

+
+## Troubleshooting
+
+### "OAuth failed"
+
+**Giải pháp:**
+- Kiểm tra kết nối internet
+- Thử browser khác
+- Xóa cache browser
+- Kết nối lại trong dashboard
+
+### "Model not available"
+
+**Giải pháp:**
+- Kiểm tra provider đã kết nối trong dashboard
+- Xác minh OAuth token hợp lệ
+- Kết nối lại provider nếu cần
+
+### "Slow responses"
+
+**Giải pháp:**
+- Free tier có thể có ưu tiên thấp hơn
+- Dùng trong giờ thấp điểm
+- Chuyển sang free provider khác
+- Nâng cấp lên cheap tier để tăng tốc
+
+---
+
+## Giới hạn
+
+### Cân nhắc Free Tier
+
+- **Tốc độ** - Có thể chậm hơn tier trả phí
+- **Ưu tiên** - Ưu tiên thấp hơn trong giờ cao điểm
+- **Rate limit** - Có thể bị rate limit (nhưng không giới hạn quota)
+- **Tính khả dụng** - Có thể có downtime thỉnh thoảng
+
+**Giải pháp:** Dùng chiến lược fallback 3 tầng để đáng tin cậy!
+
+---
+
+## Bước tiếp theo
+
+- **Setup subscriptions:** [Subscription Providers](./subscription.md)
+- **Thêm cheap backup:** [Cheap Providers](./cheap.md)
+- **Tạo combos:** Dashboard → Combos → Create New
+- **Bắt đầu code:** Dùng combo `complete-fallback` để có độ tin cậy tối đa

+
+## Ví dụ Sử dụng
+
+### Setup Cursor IDE
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [from 9router dashboard]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+### Tạo Combo (Khuyên dùng)
+
+```
+Dashboard → Combos → Create New
+
+Name: premium-coding
+Models:
+  1. gc/gemini-3-flash-preview (FREE, use first)
+  2. cc/claude-opus-4-5-20251101 (Subscription)
+  3. cx/gpt-5.2-codex (Subscription backup)
+
+Use in CLI: premium-coding
+```
+
+**Kết quả:** Tối đa free tier → Dùng subscription → Auto fallback
+
+---
+
+## Quota Tracking
+
+9Router theo dõi quota thời gian thực:
+
+- **Tiêu thụ token** - Tokens input/output mỗi request
+- **Đếm ngược reset** - Thời gian đến lần reset tiếp theo
+- **Phần trăm usage** - Đã dùng bao nhiêu quota
+- **Auto fallback** - Chuyển sang tier sau khi hết
+
+**Dashboard view:**
+
+```
+Claude Code Pro
+├─ Quota: 75% used
+├─ Reset: 2h 15m (5-hour)
+├─ Weekly reset: 3 days
+└─ Fallback: glm/glm-4.7 (cheap tier)
+```
+
+---
+
+## Best Practices
+
+### 1. Dùng Free Tier Trước
+
+```
+Priority:
+1. Gemini CLI (180K/month FREE)
+2. Antigravity (FREE Claude)
+3. Claude Code/Codex (paid subscriptions)
+```
+
+### 2. Theo dõi Quota Hàng ngày
+
+- Kiểm tra dashboard mỗi sáng
+- Lên kế hoạch task nặng quanh thời gian reset quota
+- Dùng cheap/free tier cho task không quan trọng
+
+### 3. Tạo Smart Combos
+
+```
+Example combo:
+1. gc/gemini-3-flash-preview (FREE primary)
+2. cc/claude-opus-4-5 (Complex tasks)
+3. glm/glm-4.7 (Cheap backup)
+4. if/kimi-k2-thinking (FREE fallback)
+```
+
+### 4. Tối ưu theo Thời gian
+
+```
+Morning: Fresh 5-hour quota (Claude/Codex)
+Afternoon: Gemini CLI (1K/day)
+Evening: Subscription quota
+Night: Cheap/free tier
+```
+
+---
+
+## Troubleshooting
+
+### "Quota exhausted"
+
+**Giải pháp:**
+- Kiểm tra quota tracker trong dashboard
+- Đợi reset (5 giờ hoặc hàng ngày)
+- Dùng combo fallback sang cheap/free tier
+
+### "OAuth token expired"
+
+**Giải pháp:**
+- Auto-refresh bởi 9Router
+- Nếu vẫn lỗi: Dashboard → Provider → Reconnect
+
+### "Rate limiting"
+
+**Giải pháp:**
+- Hết quota subscription
+- Thêm fallback: `cc/claude-opus → glm/glm-4.7`
+- Dùng free tier: `if/kimi-k2-thinking`
+
+---
+
+## Bước tiếp theo
+
+- **Setup cheap backup:** [Cheap Providers](./cheap.md)
+- **Thêm free fallback:** [Free Providers](./free.md)
+- **Tạo combos:** Dashboard → Combos → Create New

+# Troubleshooting
+
+Các vấn đề và giải pháp phổ biến khi dùng 9Router.
+
+---
+
+## "Language model did not provide messages"
+
+**Vấn đề:** Request thất bại với phản hồi rỗng hoặc thông báo lỗi.
+
+**Nguyên nhân:**
+- Hết quota provider
+- API key không hợp lệ hoặc hết hạn
+- Model không khả dụng
+
+**Giải pháp:**
+
+1. **Kiểm tra trạng thái quota:**
+   ```
+   Dashboard → Providers → View quota tracker
+   ```
+   Nếu hết quota, đợi reset hoặc đổi provider.
+
+2. **Dùng fallback combo:**
+   ```
+   Dashboard → Combos → Create fallback chain
+   Example: cc/claude-opus → glm/glm-4.7 → if/kimi-k2
+   ```
+
+3. **Xác minh kết nối provider:**
+   ```
+   Dashboard → Providers → Reconnect if needed
+   ```
+
+---
+
+## Rate Limiting
+
+**Vấn đề:** Lỗi "Rate limit exceeded" hoặc "Too many requests".
+
+**Nguyên nhân:**
+- Hết quota subscription (giới hạn 5h/ngày/tuần)
+- Đạt API rate limit
+- Quá nhiều request đồng thời
+
+**Giải pháp:**
+
+1. **Kiểm tra thời gian reset:**
+   ```
+   Dashboard → Quota Tracking → View reset countdown
+   ```
+
+2. **Chuyển sang tier rẻ:**
+   ```
+   Use: glm/glm-4.7 ($0.6/1M tokens)
+        minimax/MiniMax-M2.1 ($0.20/1M tokens)
+   ```
+
+3. **Thêm fallback combo:**
+   ```
+   Dashboard → Combos → Add backup models
+   Primary: cc/claude-opus (subscription)
+   Backup: glm/glm-4.7 (cheap)
+   Emergency: if/kimi-k2 (free)
+   ```
+
+---
+
+## OAuth Token hết hạn
+
+**Vấn đề:** Lỗi "Unauthorized" hoặc "Token expired".
+
+**Nguyên nhân:**
+- OAuth token hết hạn (auto-refresh thất bại)
+- Session provider không hợp lệ
+- Vấn đề network khi refresh
+
+**Giải pháp:**
+
+1. **Auto-refresh (mặc định):**
+   9Router tự refresh tokens. Đợi 30 giây rồi thử lại.
+
+2. **Kết nối lại thủ công:**
+   ```
+   Dashboard → Providers → [Provider Name] → Reconnect
+   → Complete OAuth flow again
+   ```
+
+3. **Kiểm tra trạng thái provider:**
+   Xác minh provider service đang online (Claude Code, Codex, v.v.)
+
+---
+
+## Chi phí cao
+
+**Vấn đề:** Sử dụng hoặc chi phí cao bất ngờ.
+
+**Nguyên nhân:**
+- Dùng model đắt không cần thiết
+- Không fallback sang tier rẻ hơn
+- Context window lớn
+
+**Giải pháp:**
+
+1. **Kiểm tra usage stats:**
+   ```
+   Dashboard → Usage Stats → View token consumption
+   → Identify high-cost models
+   ```
+
+2. **Chuyển sang model rẻ hơn:**
+   ```
+   Replace: cc/claude-opus ($20-100/month subscription)
+   With: glm/glm-4.7 ($0.6/1M tokens)
+         minimax/MiniMax-M2.1 ($0.20/1M tokens)
+   ```
+
+3. **Dùng free tier:**
+   ```
+   if/kimi-k2-thinking (FREE)
+   qw/qwen3-coder-plus (FREE)
+   kr/claude-sonnet-4.5 (FREE)
+   gc/gemini-3-flash-preview (FREE 180K/month)
+   ```
+
+4. **Tối ưu prompt:**
+   - Giảm context size
+   - Dùng streaming cho phản hồi dài
+   - Cache prompt thường dùng
+
+---
+
+## Connection Refused
+
+**Vấn đề:** Lỗi "ECONNREFUSED" hoặc "Cannot connect to localhost:20128".
+
+**Nguyên nhân:**
+- 9Router không chạy
+- Port 20128 bị chặn
+- Firewall chặn kết nối
+
+**Giải pháp:**
+
+1. **Khởi động 9Router:**
+   ```bash
+   9router
+   ```
+   Dashboard sẽ mở tại http://localhost:3000
+
+2. **Xác minh port 20128:**
+   ```bash
+   # Check if port is listening
+   lsof -i :20128
+   
+   # Or on Windows
+   netstat -ano | findstr :20128
+   ```
+
+3. **Kiểm tra firewall:**
+   - macOS: System Settings → Network → Firewall
+   - Windows: Windows Defender Firewall → Allow app
+   - Linux: `sudo ufw allow 20128`
+
+4. **Dùng cloud endpoint:**
+   Nếu localhost không hoạt động (ví dụ: Cursor IDE):
+   ```
+   Endpoint: https://9router.com/v1
+   ```
+
+---
+
+## Dashboard không mở
+
+**Vấn đề:** Dashboard không load tại http://localhost:3000.
+
+**Nguyên nhân:**
+- Port 3000 đã được dùng
+- 9Router bị crash
+- Vấn đề cache browser
+
+**Giải pháp:**
+
+1. **Kiểm tra 9Router có chạy không:**
+   ```bash
+   # Check process
+   ps aux | grep 9router
+   
+   # Check port 3000
+   lsof -i :3000
+   ```
+
+2. **Kill process xung đột:**
+   ```bash
+   # macOS/Linux
+   lsof -ti:3000 | xargs kill -9
+   
+   # Windows
+   netstat -ano | findstr :3000
+   taskkill /PID <PID> /F
+   ```
+
+3. **Khởi động lại 9Router:**
+   ```bash
+   # Stop
+   pkill -f 9router
+   
+   # Start
+   9router
+   ```
+
+4. **Xóa cache browser:**
+   - Chrome: Ctrl+Shift+Delete → Clear cache
+   - Thử chế độ ẩn danh
+
+5. **Kiểm tra cài đặt firewall:**
+   Đảm bảo port 3000 không bị chặn.
+
+---
+
+## Model Not Found
+
+**Vấn đề:** Lỗi "Model not found" hoặc "Invalid model".
+
+**Nguyên nhân:**
+- Provider chưa kết nối
+- Sai chính tả model ID
+- Provider không hoạt động
+
+**Giải pháp:**
+
+1. **Xác minh kết nối provider:**
+   ```
+   Dashboard → Providers → Check status (green = active)
+   ```
+
+2. **Kiểm tra format model ID:**
+   ```
+   Correct: cc/claude-opus-4-5-20251101
+   Wrong: claude-opus-4-5-20251101
+   
+   Format: [provider-prefix]/[model-name]
+   ```
+
+3. **Liệt kê model khả dụng:**
+   ```bash
+   curl http://localhost:20128/v1/models \
+     -H "Authorization: Bearer your-api-key"
+   ```
+
+4. **Kết nối lại provider:**
+   ```
+   Dashboard → Providers → [Provider] → Reconnect
+   ```
+
+---
+
+## Phản hồi chậm
+
+**Vấn đề:** Request mất quá lâu hoặc timeout.
+
+**Nguyên nhân:**
+- Độ trễ provider
+- Vấn đề network
+- Context/response lớn
+- Provider rate limiting
+
+**Giải pháp:**
+
+1. **Kiểm tra trạng thái provider:**
+   ```
+   Dashboard → Providers → View latency stats
+   ```
+
+2. **Chuyển sang model nhanh hơn:**
+   ```
+   Fast: cc/claude-haiku-4-5 (Haiku is faster than Opus)
+         gc/gemini-3-flash-preview
+         qw/qwen3-coder-flash
+   ```
+
+3. **Dùng streaming:**
+   ```json
+   {
+     "model": "cc/claude-opus-4-5",
+     "messages": [...],
+     "stream": true
+   }
+   ```
+
+4. **Kiểm tra network:**
+   ```bash
+   # Test latency
+   ping api.anthropic.com
+   ping api.openai.com
+   ```
+
+5. **Giảm context size:**
+   - Cắt bớt lịch sử tin nhắn
+   - Dùng prompt nhỏ hơn
+   - Bật context pruning trong CLI tool
+
+---
+
+## API Key không hợp lệ
+
+**Vấn đề:** Lỗi "Invalid API key" hoặc "Authentication failed".
+
+**Nguyên nhân:**
+- Sao chép sai API key
+- API key hết hạn
+- API key chưa được tạo
+
+**Giải pháp:**
+
+1. **Tạo lại API key:**
+   ```
+   Dashboard → Settings → API Keys → Generate New Key
+   → Copy and use new key
+   ```
+
+2. **Xác minh format key:**
+   ```
+   Correct: 9r_xxxxxxxxxxxxxxxxxxxxxxxx
+   Wrong: Missing 9r_ prefix
+   ```
+
+3. **Kiểm tra key trong CLI config:**
+   ```bash
+   # Cursor
+   Settings → Models → OpenAI API Key
+   
+   # Cline
+   Settings → API Key
+   
+   # Environment variable
+   export OPENAI_API_KEY="9r_your_key"
+   ```
+
+4. **Test API key:**
+   ```bash
+   curl http://localhost:20128/v1/models \
+     -H "Authorization: Bearer 9r_your_key"
+   ```

+## 🌐 Nginx 反向代理
+
+### 为什么使用 Nginx?
+
+- SSL/TLS 终止
+- 域名映射
+- 负载均衡
+- 更好的安全性
+
+### 步骤 1:安装 Nginx
+
+```bash
+sudo apt update
+sudo apt install nginx
+```
+
+### 步骤 2:配置 Nginx
+
+创建 `/etc/nginx/sites-available/9router`:
+
+```nginx
+server {
+    listen 80;
+    server_name your-domain.com;
+
+    # Redirect HTTP to HTTPS
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name your-domain.com;
+
+    # SSL certificates (use certbot to generate)
+    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
+
+    # SSL configuration
+    ssl_protocols TLSv1.2 TLSv1.3;
+    ssl_ciphers HIGH:!aNULL:!MD5;
+    ssl_prefer_server_ciphers on;
+
+    # Proxy to 9Router
+    location / {
+        proxy_pass http://localhost:3000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_cache_bypass $http_upgrade;
+        
+        # SSE support - CRITICAL for streaming
+        proxy_buffering off;
+        proxy_read_timeout 86400;
+    }
+
+    # API endpoint
+    location /v1 {
+        proxy_pass http://localhost:20128;
+        proxy_http_version 1.1;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        
+        # SSE support - CRITICAL for streaming
+        proxy_buffering off;
+        proxy_read_timeout 86400;
+    }
+}
+```
+
+### 步骤 3:启用站点
+
+```bash
+# 创建软链接
+sudo ln -s /etc/nginx/sites-available/9router /etc/nginx/sites-enabled/
+
+# 测试配置
+sudo nginx -t
+
+# 重新加载 Nginx
+sudo systemctl reload nginx
+```
+
+### 步骤 4:使用 Let's Encrypt 配置 SSL
+
+```bash
+# 安装 certbot
+sudo apt install certbot python3-certbot-nginx
+
+# 获取 SSL 证书
+sudo certbot --nginx -d your-domain.com
+
+# 自动续期已自动配置
+# 测试续期
+sudo certbot renew --dry-run
+```
+
+---
+
+## 🔒 安全注意事项
+
+### 1. 修改默认凭据
+
+**关键:** 部署前修改 `JWT_SECRET` 和 `INITIAL_PASSWORD`:
+
+```bash
+# 生成安全的 JWT secret
+openssl rand -base64 32
+
+# 将该值用于 JWT_SECRET
+export JWT_SECRET="generated-secret-here"
+```
+
+### 2. 防火墙配置
+
+```bash
+# 允许 SSH
+sudo ufw allow 22/tcp
+
+# 允许 HTTP/HTTPS(若使用 Nginx)
+sudo ufw allow 80/tcp
+sudo ufw allow 443/tcp
+
+# 若不使用反向代理,放开 9Router 端口
+sudo ufw allow 3000/tcp
+sudo ufw allow 20128/tcp
+
+# 启用防火墙
+sudo ufw enable
+```
+
+### 3. 限制仪表盘访问
+
+如果只需要 API 访问,可限制仪表盘端口:
+
+```bash
+# 仅允许 localhost 访问仪表盘
+sudo ufw deny 3000/tcp
+```
+
+通过 SSH 隧道访问仪表盘:
+
+```bash
+ssh -L 3000:localhost:3000 user@your-server.com
+# 然后在浏览器打开 http://localhost:3000
+```
+
+### 4. 定期更新
+
+```bash
+# 更新系统包
+sudo apt update && sudo apt upgrade -y
+
+# 更新 9Router
+cd /path/to/9router/app
+git pull
+npm install
+npm run build
+pm2 restart 9router
+```
+
+### 5. 备份策略
+
+```bash
+# 备份数据目录
+tar -czf 9router-backup-$(date +%Y%m%d).tar.gz /var/lib/9router
+
+# 每日自动备份(加入 crontab)
+0 2 * * * tar -czf /backups/9router-$(date +\%Y\%m\%d).tar.gz /var/lib/9router
+```
+
+---
+
+## 📊 监控
+
+### 检查应用状态
+
+```bash
+# PM2 状态
+pm2 status
+
+# 查看日志
+pm2 logs 9router --lines 100
+
+# 监控资源
+pm2 monit
+```
+
+### Nginx 日志
+
+```bash
+# 访问日志
+sudo tail -f /var/log/nginx/access.log
+
+# 错误日志
+sudo tail -f /var/log/nginx/error.log
+```
+
+### 系统资源
+
+```bash
+# CPU 和内存使用
+htop
+
+# 磁盘使用
+df -h
+
+# 网络连接
+netstat -tulpn | grep -E '3000|20128'
+```
+
+---
+
+## 🚨 故障排除
+
+### 应用无法启动
+
+```bash
+# 查看日志
+pm2 logs 9router
+
+# 检查端口是否被占用
+sudo lsof -i :3000

+---
+
+## 什么是 9Router?
+
+**9Router 是一款 AI 模型路由工具,能够最大化你的订阅价值并最小化成本。**
+
+它使用 3 层回退系统在多个 AI 提供商之间智能路由请求:
+1. **订阅层** - 充分利用你已付费的 Claude Code、Codex、Gemini 配额
+2. **低价层** - 超低价替代方案(每 1M tokens $0.20-$0.60)
+3. **免费层** - 无限免费模型应急备用
+
+**核心优势:**
+- 不再浪费订阅配额
+- 配额耗尽时自动回退
+- 实时配额跟踪
+- 比直接使用 API 节省 90% 成本
+
+---
+
+## 价格是如何计算的?
+
+**9Router 采用三层定价策略:**
+
+### 第 1 层:订阅(优先使用)
+- **Claude Code**(Pro/Max):$20-100/月 - 5 小时 + 每周配额
+- **OpenAI Codex**(Plus/Pro):$20-200/月 - 5 小时 + 每周配额
+- **Gemini CLI**:免费 - 每月 180K 次补全 + 每天 1K
+- **GitHub Copilot**:$10-19/月 - 每月重置
+- **Antigravity**:免费 - 类似 Gemini
+
+**目标:** 在配额重置前用掉每一点!
+
+### 第 2 层:低价(备用)
+- **GLM-4.7**:每 1M tokens $0.60/$2.20 - 每日 10AM 重置
+- **MiniMax M2.1**:每 1M tokens $0.20/$1.00 - 5 小时滚动
+- **Kimi K2**:$9/月固定(10M tokens)
+
+**目标:** 比 ChatGPT API(每 1M $20)便宜 90%!
+
+### 第 3 层:免费(应急)
+- **iFlow**:8 个免费模型(Kimi K2、Qwen3、GLM、MiniMax...)
+- **Qwen**:3 个免费模型(Qwen3 Coder Plus/Flash、Vision)
+- **Kiro**:2 个免费模型(Claude Sonnet 4.5、Haiku 4.5)
+
+**目标:** 当其他配额都受限时零成本回退!
+
+---
+
+## 9Router 是免费的吗?

+
+---
+
+## 可以同时使用多个提供商吗?
+
+**可以!这正是 9Router 的核心功能。**
+
+**通过组合(Combos),你可以把多个提供商串联起来实现自动回退:**
+
+```
+示例组合: "premium-coding"
+1. cc/claude-opus-4-5(订阅主力)
+2. glm/glm-4.7(低价备用)
+3. if/kimi-k2(免费应急)
+
+→ 配额耗尽时自动切换
+→ 永不停止编码
+→ 几乎零额外成本
+```
+
+**创建组合的方法:**
+```
+仪表盘 → 组合 → 新建
+→ 按优先级添加模型
+→ CLI 中使用组合名: "premium-coding"
+```
+
+**优势:**
+- 配额耗尽时零停机
+- 自动成本优化
+- 所有工具使用同一个模型名
+
+详情见 [组合文档](features/combos.md)。
+
+---
+
+## 配额跟踪是如何工作的?
+
+**9Router 为所有提供商提供实时配额跟踪:**
+
+**功能:**
+- **Token 消耗** - 每次请求的输入/输出 tokens
+- **重置倒计时** - 配额刷新前剩余时间
+- **使用统计** - 每日/每周/每月报告
+- **成本估算** - 预计支出(付费层)
+- **配额告警** - 配额不足时通知
+
+**配额类型:**
+- **5 小时滚动** - Claude Code、Codex、MiniMax
+- **每日重置** - Gemini CLI(每日 1K)、GLM(10AM)
+- **每周重置** - Claude Code、Codex(额外配额)
+- **每月重置** - Gemini CLI(180K)、GitHub Copilot(1 日)
+
+**查看配额:**
+```
+仪表盘 → 提供商 → 配额跟踪
+→ 实时使用情况 + 重置倒计时
+```
+
+详情见 [配额跟踪文档](features/quota-tracking.md)。
+
+---
+
+## 9Router 能配合 Cursor 使用吗?
+
+**可以,但 Cursor 需要使用云端 endpoint。**
+
+**问题:** Cursor IDE 不支持 localhost endpoint。
+
+**解决方案:** 使用 9Router 云端部署:
+
+```
+Cursor Settings → Models → Advanced:
+  OpenAI API Base URL: https://9router.com/v1
+  OpenAI API Key: [从仪表盘获取]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+**替代方案:** 在 VPS 上自托管,使用公开域名:
+```bash
+# 部署到 VPS
+git clone https://github.com/decolua/9router.git
+cd 9router/app
+npm install && npm run build
+npm start
+
+# 配置 Nginx 反向代理
+# 将 Cursor 指向: https://your-domain.com/v1
+```
+
+**其他 CLI 工具支持 localhost:**
+- Cline ✅
+- Claude Desktop ✅
+- Codex CLI ✅
+- Continue ✅
+- RooCode ✅
+
+详情见 [Cursor 集成指南](integration/cursor.md)。
+
+---
+
+## 可以自托管 9Router 吗?
+
+**可以!9Router 支持多种部署方式:**
+
+### Localhost(默认)
+```bash
+npm install -g 9router
+9router
+→ 仪表盘: http://localhost:3000
+→ API: http://localhost:20128/v1
+```
+
+### VPS/云
+```bash
+git clone https://github.com/decolua/9router.git
+cd 9router/app
+npm install && npm run build
+
+export JWT_SECRET="your-secure-secret"
+export INITIAL_PASSWORD="your-password"
+export NODE_ENV="production"
+
+npm start
+```
+
+### Docker
+```bash
+docker build -t 9router .
+docker run -d \
+  -p 3000:3000 \
+  -e JWT_SECRET="your-secret" \
+  -v 9router-data:/app/data \
+  9router
+```
+
+### Cloudflare Workers
+```bash
+cd 9router/app
+npm run deploy:cloudflare
+```
+
+**环境变量:**
+- `JWT_SECRET` - **生产环境必须修改!**
+- `DATA_DIR` - 数据库存储路径(默认:`~/.9router`)
+- `INITIAL_PASSWORD` - 仪表盘登录(默认:`123456`)
+- `NODE_ENV` - 部署时设为 `production`
+
+详情见 [部署指南](getting-started/installation.md#deployment)。
+
+---
+
+## 我的数据安全吗?
+
+**是的,9Router 优先考虑安全和隐私:**
+
+**本地存储:**

+- 不会发送数据到 9Router 服务器
+- OAuth tokens 使用 JWT 加密
+
+**无遥测:**
+- 不跟踪使用情况
+- 不分析
+- 不向外回连
+
+**开源:**
+- GitHub 上提供完整源码
+- 可自行审计安全性
+- 社区评审
+
+**最佳实践:**
+- 生产环境修改 `JWT_SECRET`
+- 使用强 `INITIAL_PASSWORD`
+- 云端部署启用 HTTPS
+- 定期轮换 API keys
+
+**9Router 存储的内容:**
+- 提供商 OAuth tokens(加密)
+- API keys(加密)

+# 组合(Combos)- 自定义回退链
+
+创建自定义的模型组合并自动回退。组合让你根据成本、质量和可用性定义自己的路由策略。
+
+---
+
+## 什么是组合?
+
+组合是你在仪表盘中创建的 **自定义回退链**。它不是单一模型,而是定义一组顺序模型,由 9Router 依次尝试。
+
+**示例:**
+```
+组合名: premium-coding
+模型:
+  1. cc/claude-opus-4-5-20251101 (首选)
+  2. glm/glm-4.7 (#1 配额耗尽时)
+  3. minimax/MiniMax-M2.1 (#2 配额耗尽时)
+```
+
+**CLI 中使用:**
+```
+Model: premium-coding
+```
+
+9Router 会按顺序自动尝试每个模型,直到成功为止。
+
+---
+
+## 为什么使用组合?
+
+### 1. 最大化订阅价值
+```

+```
+
+**日常安排:**
+```
+08:00 - 13:00: Claude Code(全新 5h 配额)
+13:00 - 18:00: Gemini CLI(每日 1K 配额)
+18:00 - 22:00: GLM(次日 10AM 重置)
+22:00 - 08:00: MiniMax(5h 滚动)或 iFlow
+```
+
+**结果**:24/7 编码,成本极低。
+
+---
+
+## 在 CLI 工具中使用组合
+
+### Cursor IDE
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [从仪表盘获取]
+  Model: premium-coding
+```
+
+### Claude Desktop
+
+编辑 `~/.claude/config.json`:
+```json
+{
+  "anthropic_api_base": "http://localhost:20128/v1",
+  "anthropic_api_key": "your-9router-api-key",
+  "model": "budget-combo"
+}
+```
+
+### Codex CLI
+
+```bash
+export OPENAI_BASE_URL="http://localhost:20128"
+export OPENAI_API_KEY="your-9router-api-key"
+
+codex --model quality-first "your prompt"
+```
+
+### Cline / Continue / RooCode
+
+```
+Provider: OpenAI Compatible
+Base URL: http://localhost:20128/v1
+API Key: [从仪表盘获取]
+Model: free-combo
+```
+
+### API 请求
+
+```bash
+curl http://localhost:20128/v1/chat/completions \
+  -H "Authorization: Bearer your-api-key" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "premium-coding",
+    "messages": [
+      {"role": "user", "content": "Write a function to..."}
+    ],
+    "stream": true
+  }'
+```
+
+---
+
+## 最佳实践
+
+### 1. 总是包含免费层
+
+```
+✅ 好:
+cc/claude-opus → glm/glm-4.7 → if/kimi-k2-thinking
+
+❌ 不好:
+cc/claude-opus → glm/glm-4.7
+(无免费回退,可能耗尽配额)
+```
+
+**原因**:确保 24/7 可用,绝不会被配额卡住。
+
+### 2. 按成本排序(便宜 → 贵)
+
+```
+✅ 好:
+glm/glm-4.7 → minimax/MiniMax-M2.1 → cc/claude-opus
+
+❌ 不好:
+cc/claude-opus → glm/glm-4.7
+(在简单任务上浪费订阅配额)
+```
+
+**例外**:如果想充分利用订阅价值,把订阅放在最前面。
+
+### 3. 匹配质量要求
+
+```
+生产代码:
+cc/claude-opus → cx/gpt-5.2-codex → glm/glm-4.7
+
+简单任务:
+glm/glm-4.7 → if/kimi-k2-thinking
+
+试验:
+if/kimi-k2-thinking → qw/qwen3-coder-plus
+```
+
+### 4. 考虑配额重置时间
+
+```
+早上组合(配额刚刷新):
+cc/claude-opus → cx/gpt-5.2-codex
+
+晚上组合(配额大概率耗尽):
+glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+```
+
+### 5. 为不同场景创建多个组合
+
+```
+premium-coding: 复杂任务
+budget-combo: 简单任务
+free-combo: 试验
+quality-first: 生产代码
+```
+
+**根据任务需求切换组合**。
+
+### 6. 监控组合性能
+
+```
+仪表盘 → 分析 → 组合使用:
+  premium-coding:
+    80% 通过 cc/claude-opus(良好,使用订阅)
+    15% 通过 glm/glm-4.7(可接受备用)
+    5% 通过 minimax(罕见回退)
+```
+
+**优化**:回退使用过多时,提高主配额或重新排序模型。
+
+---
+
+## 高级配置
+
+### 为组合设置预算上限
+
+```
+仪表盘 → 组合 → 编辑 → 预算:
+  每日上限: $5
+  每月上限: $50
+```
+
+达到上限时,9Router 跳过付费模型,仅使用免费层。
+
+### 启用/禁用组合中的模型
+
+```
+仪表盘 → 组合 → 编辑 → 模型:
+  ✅ cc/claude-opus-4-5(启用)
+  ❌ glm/glm-4.7(暂时禁用)
+  ✅ if/kimi-k2-thinking(启用)
+```
+
+**用途**:暂时禁用昂贵模型而不删除组合。
+
+### 克隆已有组合
+
+```
+仪表盘 → 组合 → 克隆 "premium-coding"
+→ 生成带 "-copy" 后缀的副本
+→ 修改后另存为新组合
+```
+
+**用途**:为不同场景创建变体。
+
+---
+
+## 故障排除
+
+**问题:组合未出现在模型列表中**
+
+**方案:**
+1. 刷新仪表盘
+2. 检查组合已保存(绿色对勾)
+3. 重启 CLI 工具以刷新模型列表
+
+**问题:组合总是用最后一个模型(免费层)**
+
+**方案:**
+1. 检查主模型的配额(仪表盘 → 配额)
+2. 确认 API keys 有效(仪表盘 → 提供商)
+3. 检查是否超出预算上限
+
+**问题:组合成本超出预期**
+
+**方案:**
+1. 仪表盘 → 分析 → 查看组合使用情况
+2. 检查主模型是否配额耗尽
+3. 重新排序模型(更便宜的放前面)
+4. 设置预算上限

+   原因: GLM-4.7 高用量(20M tokens)
+   建议: 检查主模型是否配额耗尽
+```
+
+---
+
+## 最佳实践
+
+### 1. 每日监控配额
+
+```
+日常:
+1. 查看仪表盘配额概览(30 秒)
+2. 检查重置时间
+3. 根据配额可用性规划使用
+```
+
+**示例:**
+```
+早晨检查:
+  ✅ Claude Code: 5h 可用(刚重置)
+  ✅ Gemini CLI: 1K 请求可用
+  ⚠️ GLM-4.7: 剩 2M tokens(10AM 重置)
+  
+行动: 早上工作用 Claude Code
+```
+
+### 2. 设置预算上限
+
+```
+仪表盘 → 设置 → 预算:
+  每日: $5(防止超支)
+  每月: $150(与预算对齐)
+```
+
+**结果**:达到上限时自动切换到免费层。
+
+### 3. 优化组合使用
+
+```
+仪表盘 → 分析 → 组合:
+  查看哪些模型用得最多
+  调整组合顺序以最小化成本
+```
+
+**示例:**
+```
+当前: cc/claude-opus → glm/glm-4.7
+  80% 通过 Claude(好)
+  20% 通过 GLM($12/月)
+
+优化后: gc/gemini-3-flash → cc/claude-opus → glm/glm-4.7
+  50% 通过 Gemini(免费)
+  40% 通过 Claude(订阅)
+  10% 通过 GLM($6/月)
+  
+节省: $6/月
+```
+
+### 4. 跟踪重置时间
+
+```
+仪表盘 → 配额 → 重置日程:
+  Claude Code: 5h 滚动 + 每周一
+  Gemini CLI: 每日 00:00 UTC + 每月 1 日
+  GLM-4.7: 每日 10:00 AM 北京时间
+  MiniMax: 5h 滚动窗口
+```
+
+**策略**:配额刚刷新时使用对应提供商。
+
+### 5. 查看月度报告
+
+```
+仪表盘 → 分析 → 月度报告:
+  总 tokens: 1.5B
+  总成本: $120
+  节省: 相比 ChatGPT API 节省 97%
+  
+洞察:
+  - 60% 用量来自订阅($0)
+  - 30% 通过 GLM($90)
+  - 10% 通过免费层($0)
+  
+优化:
+  - 增加 Gemini CLI 用量(免费)
+  - 减少 GLM 用量(更贵)

+# 智能路由 & 自动回退
+
+9Router 通过 3 层回退系统,自动将你的请求路由到最佳可用提供商。绝不再因配额限制或速率限制而中断编码。
+
+---
+
+## 工作原理
+
+9Router 使用智能路由,最大化已有订阅价值、最小化成本,并保障 24/7 可用:
+
+```
+请求 → 9Router → 检查第 1 层 (订阅)
+                     ↓ 配额耗尽
+                     检查第 2 层 (低价)
+                     ↓ 预算上限
+                     检查第 3 层 (免费)
+                     ↓
+                     响应
+```
+
+### 3 层回退系统
+
+**第 1 层:订阅(主力)**
+- Claude Code(Pro/Max)
+- OpenAI Codex(Plus/Pro)
+- Gemini CLI(每月免费 180K)
+- GitHub Copilot
+- Antigravity(Google)
+
+**目标**:充分挖掘你已付费订阅的价值。
+
+**第 2 层:低价(备用)**
+- GLM-4.7(输入每 1M $0.60)
+- MiniMax M2.1(输入每 1M $0.20)
+- Kimi K2($9/月固定)
+
+**目标**:订阅配额用完后的超低价备用(比 ChatGPT API 便宜 ~90%)。
+
+**第 3 层:免费(应急)**
+- iFlow(8 个模型)
+- Qwen(3 个模型)
+- Kiro(Claude 免费)
+
+**目标**:零成本回退,实现无限编码。
+
+---
+
+## 自动切换
+
+9Router 实时监控配额,自动切换提供商:
+
+### 场景 1:订阅配额耗尽
+
+```
+用户请求 → cc/claude-opus-4-5
+           ↓ 配额耗尽(达到 5 小时限制)
+           自动切换 → glm/glm-4.7
+           ↓ 每日配额耗尽
+           自动切换 → minimax/MiniMax-M2.1
+           ↓ 5 小时配额耗尽
+           自动切换 → if/kimi-k2-thinking (免费)
+           ↓
+           响应已送达 ✅
+```
+
+**结果**:零停机,无缝体验。
+
+### 场景 2:速率限制
+
+```
+用户请求 → cx/gpt-5.2-codex
+           ↓ 速率受限(请求过多)
+           自动切换 → glm/glm-4.7
+           ↓
+           响应已送达 ✅
+```
+
+### 场景 3:提供商不可用
+
+```
+用户请求 → cc/claude-opus-4-5
+           ↓ 提供商错误(503)
+           自动切换 → 下一个可用模型
+           ↓
+           响应已送达 ✅
+```
+
+---
+
+## 模型选择逻辑
+
+9Router 基于以下因素选择最佳模型:
+
+1. **配额可用性** - 检查提供商是否仍有剩余配额
+2. **成本层级** - 优先订阅 → 低价 → 免费
+3. **重置时间** - 考虑配额何时重置
+4. **提供商健康度** - 跳过有错误的提供商
+
+### 优先级示例
+
+对 `cc/claude-opus-4-5` 的请求:
+
+```
+1. 检查 Claude Code 配额
+   ✅ 可用 → 使用 cc/claude-opus-4-5
+   ❌ 耗尽 → 继续步骤 2
+
+2. 检查回退层(若已配置)
+   ✅ GLM 配额可用 → 使用 glm/glm-4.7
+   ❌ 耗尽 → 继续步骤 3
+
+3. 检查免费层
+   ✅ iFlow 可用 → 使用 if/kimi-k2-thinking
+   ❌ 全部耗尽 → 返回配额错误
+```
+
+---
+
+## 配置选项
+
+### 仪表盘设置
+
+**1. 启用/禁用自动回退**
+
+```
+仪表盘 → 设置 → 智能路由
+→ 切换 "Auto Fallback" ON/OFF
+```
+
+- **ON**(默认):自动层级切换
+- **OFF**:严格模式,主模型不可用时返回错误
+
+**2. 设置预算上限**
+
+```
+仪表盘 → 设置 → 预算控制
+→ 每日上限: $5
+→ 每月上限: $50
+```
+
+预算耗尽时,9Router 自动切换到免费层。
+
+**3. 配置回退顺序**
+
+```
+仪表盘 → 设置 → 回退优先级
+→ 拖动以重新排序每层内的提供商
+```
+
+自定义顺序示例:
+```
+第 1 层: Gemini CLI → Claude Code → Codex
+第 2 层: MiniMax → GLM → Kimi
+第 3 层: iFlow → Kiro → Qwen
+```
+
+**4. 配额重置通知**
+
+```
+仪表盘 → 设置 → 通知
+→ 配额重置时邮件提醒
+→ 配额使用 80% 时告警
+```
+
+---
+
+## 示例
+
+### 示例 1:基础自动回退
+
+**设置:**
+```
+Model: cc/claude-opus-4-5-20251101
+Fallback: 自动(默认 3 层)
+```
+
+**行为:**
+```
+早上(全新配额):
+  请求 → cc/claude-opus-4-5 ✅
+
+下午(配额耗尽):
+  请求 → glm/glm-4.7 ✅ (自动切换)
+
+晚上(GLM 配额用完):
+  请求 → minimax/MiniMax-M2.1 ✅ (自动切换)
+
+深夜(付费配额全部耗尽):
+  请求 → if/kimi-k2-thinking ✅ (免费层)
+```
+
+**成本**:额外约 $5-10/月(大部分由订阅覆盖)。
+
+### 示例 2:预算优先路由
+
+**设置:**
+```
+仪表盘 → 设置:
+  每日预算: $2
+  每月预算: $20
+  Fallback: 启用
+```
+
+**行为:**
+```
+1-15 日(预算内):
+  请求 → glm/glm-4.7 (低价层)
+  成本: $1.50/天
+
+第 16 日(达到预算):
+  请求 → if/kimi-k2-thinking (免费层)
+  成本: $0
+
+下月(预算重置):
+  请求 → 重新使用 glm/glm-4.7
+```
+
+**结果**:绝不超过 $20/月,始终可用。
+
+### 示例 3:仅订阅模式
+
+**设置:**
+```
+仪表盘 → 设置:
+  Auto Fallback: OFF
+  Strict mode: ON
+```
+
+**行为:**
+```
+请求 → cc/claude-opus-4-5
+  ✅ 配额可用 → 成功
+  ❌ 配额耗尽 → 返回错误(无回退)
+```
+
+**适用场景**:只想用付费订阅,绝不产生额外成本。
+
+### 示例 4:仅免费模式
+
+**设置:**
+```
+Model: if/kimi-k2-thinking
+Fallback: qw/qwen3-coder-plus → kr/claude-sonnet-4.5
+```
+
+**行为:**
+```
+所有请求 → 仅免费层
+成本: 永远 $0
+```
+
+**适用场景**:个人项目、学习、试验。
+
+---
+
+## 最佳实践
+
+### 1. 最大化订阅价值
+
+```
+策略:
+- 将订阅模型设为第 1 层
+- 在仪表盘监控配额使用
+- 仅在订阅耗尽时使用低价层
+```
+
+**示例组合:**
+```
+cc/claude-opus-4-5 → glm/glm-4.7 → if/kimi-k2-thinking
+```
+
+### 2. 成本优化
+
+```
+策略:
+- 先用 Gemini CLI 免费层(每月 180K)
+- 回退到 GLM/MiniMax(超低价)
+- 应急: iFlow(免费)
+```
+
+**示例组合:**
+```
+gc/gemini-3-flash-preview → glm/glm-4.7 → if/kimi-k2-thinking
+```
+
+### 3. 质量优先
+
+```
+策略:
+- 使用最佳模型(Claude Opus、GPT-5.2)
+- 回退到优秀的低价模型(GLM-4.7)
+- 最后手段: 免费层
+```
+
+**示例组合:**
+```
+cc/claude-opus-4-5 → cx/gpt-5.2-codex → glm/glm-4.7
+```
+
+### 4. 24/7 可用性
+
+```
+策略:
+- 回退链中总是包含免费层
+- 监控配额重置时间
+- 在多个提供商间分散使用
+```
+
+**示例组合:**
+```
+cc/claude-opus-4-5 → glm/glm-4.7 → minimax/MiniMax-M2.1 → if/kimi-k2-thinking
+```
+
+**结果**:永不耗尽配额,随时编码。
+
+---
+
+## 配额重置策略
+
+围绕配额重置时间规划使用:
+
+| 提供商 | 配额重置 | 策略 |
+|----------|-------------|----------|
+| **Claude Code** | 5 小时 + 每周 | 早上使用,配额最新鲜 |
+| **Codex** | 5 小时 + 每周 | Claude 配额用完后使用 |
+| **Gemini CLI** | 每日(1K)+ 每月(180K) | 全天均匀使用 |
+| **GLM-4.7** | 每日 10:00 AM | 晚上使用,次日上午重置 |
+| **MiniMax M2.1** | 5 小时滚动 | 任意时间用,跟踪滚动窗口 |
+| **iFlow/Qwen/Kiro** | 无限制 | 应急备用 |
+
+**日常安排示例:**
+```
+08:00 - 13:00: Claude Code(全新 5h 配额)
+13:00 - 18:00: Gemini CLI(每日 1K 配额)
+18:00 - 22:00: GLM-4.7(便宜,10AM 重置)
+22:00 - 08:00: MiniMax 或 iFlow(5h 滚动 或 免费)
+```
+
+---
+
+## 监控与告警
+
+### 仪表盘配额跟踪
+
+```
+仪表盘 → 配额概览:
+  Claude Code: 剩余 2.5h / 5h (50%)
+  Gemini CLI: 今日 450 / 1000 次请求
+  GLM-4.7: 5M / 10M tokens (8h 后重置)
+  MiniMax: 3M / 5M tokens (5h 滚动)
+```
+
+### 实时通知
+
+```
+仪表盘 → 通知:
+  ⚠️ Claude Code 配额使用 80%(剩 1h)
+  ✅ GLM-4.7 配额已重置(10M tokens 可用)
+  💰 每日预算使用 50%($2.50 / $5)
+```
+
+### 使用分析
+
+```
+仪表盘 → 分析:
+  今日: 50M tokens
+    - 30M 通过 Claude Code(订阅)
+    - 15M 通过 GLM-4.7($9)
+    - 5M 通过 iFlow(免费)
+  
+  成本: $9(对比 ChatGPT API $1000)
+  节省: 99%
+```
+
+---
+
+## 故障排除
+
+**问题:"All providers quota exhausted"**
+
+**方案:**
+1. 查看仪表盘配额跟踪
+2. 等待配额重置(查看倒计时)
+3. 在回退链中加入免费层
+4. 或提高预算上限
+
+**问题:"Too many fallback switches"**
+
+**方案:**
+1. 检查主提供商是否宕机
+2. 提高配额上限(升级订阅)
+3. 使用更便宜的主模型(用 GLM 代替 Claude)
+
+**问题:"Unexpected costs"**
+
+**方案:**
+1. 仪表盘 → 分析 → 查看使用情况
+2. 设置每日/每月预算上限
+3. 非关键任务切换到免费层
+4. 使用带免费回退的组合

+# 入门指南
+
+5 分钟启动 9Router,开始智能路由 AI 请求。
+
+---
+
+## 快速开始
+
+### 1. 安装
+
+```bash
+npm install -g 9router
+```
+
+**要求:** Node.js 20+([安装详情](getting-started/installation.md))
+
+### 2. 启动
+
+```bash
+9router
+```
+
+🎉 **仪表盘自动打开** 地址为 `http://localhost:20128`
+
+- 默认密码:`123456`(在仪表盘中修改)
+- API key 自动生成
+- 可立即连接提供商
+
+### 3. 连接提供商
+
+有 3 种方式连接提供商:
+
+#### 方式 A:OAuth(订阅型提供商)
+
+**适用于:** Claude Code、Codex、Gemini CLI、GitHub Copilot
+
+```
+仪表盘 → 提供商 → 连接 [提供商]
+→ OAuth 登录 → 自动刷新 token
+→ 启用配额跟踪
+```
+
+**示例:Claude Code**
+1. 点击 "Connect Claude Code"
+2. 用你的 Claude 账户登录
+3. 授权 9Router
+4. ✅ 完成!使用模型:`cc/claude-opus-4-5-20251101`
+
+#### 方式 B:API Key(低价提供商)
+
+**适用于:** GLM、MiniMax、Kimi、OpenRouter
+
+```
+仪表盘 → 提供商 → 添加 API Key
+→ 选择提供商
+→ 粘贴 API key
+→ 保存
+```
+
+**示例:GLM-4.7**
+1. 在 [Zhipu AI](https://open.bigmodel.cn/) 注册
+2. 从 Coding Plan 获取 API key
+3. 仪表盘 → 添加 API Key → 提供商:`glm` → 粘贴 key
+4. ✅ 完成!使用模型:`glm/glm-4.7`
+
+#### 方式 C:免费提供商(零成本)
+
+**适用于:** iFlow、Qwen、Kiro
+
+```
+仪表盘 → 提供商 → 连接 [免费提供商]
+→ 设备码或 OAuth
+→ 无限使用
+```
+
+**示例:iFlow**
+1. 点击 "Connect iFlow"
+2. 用 iFlow 账户登录
+3. 授权
+4. ✅ 完成!使用 8 个模型:`if/kimi-k2-thinking`、`if/qwen3-coder-plus` 等
+
+---
+
+## 4. 在 CLI 工具中使用
+
+将你的编码工具指向 9Router:
+
+### Cursor IDE
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [从 9router 仪表盘获取]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+### Claude Desktop
+
+编辑 `~/.claude/config.json`:
+
+```json
+{
+  "anthropic_api_base": "http://localhost:20128/v1",
+  "anthropic_api_key": "your-9router-api-key"
+}
+```
+
+### Cline / Continue / RooCode
+
+```
+Provider: OpenAI Compatible
+Base URL: http://localhost:20128/v1
+API Key: [从仪表盘获取]
+Model: cc/claude-opus-4-5-20251101
+```
+
+### Codex CLI
+
+```bash
+export OPENAI_BASE_URL="http://localhost:20128"
+export OPENAI_API_KEY="your-9router-api-key"
+
+codex "your prompt"
+```
+
+---
+
+## 5. 创建智能组合(可选)
+
+组合(Combos)可在多个模型之间实现自动回退:
+
+```
+仪表盘 → 组合 → 新建
+
+名称: premium-coding
+模型:
+  1. cc/claude-opus-4-5-20251101 (订阅主力)
+  2. glm/glm-4.7 (低价备用, $0.6/1M)
+  3. if/kimi-k2-thinking (免费回退)
+
+CLI 中使用: premium-coding
+```
+
+**工作原理:**
+1. 先尝试 Claude Opus(你的订阅)
+2. 配额耗尽 → GLM-4.7(超低价)
+3. 预算上限 → iFlow(免费)
+4. 零停机,自动切换!
+
+---
+

+
+真实案例(每月 100M tokens):
+  60M 通过 Gemini CLI: $0(免费层)
+  30M 通过 Claude Code: $0(你已有的订阅)
+  8M 通过 GLM: $4.80
+  2M 通过 MiniMax: $0.40
+  合计: $5.20/月 + 已有订阅
+```
+
+### 配额重置策略
+
+```
+日常安排:
+1. 早上: 全新的 Claude Code 配额(5h 重置)
+2. 下午: 切换到 Gemini CLI(每日 1K)
+3. 晚上: GLM 每日配额(次日 10AM 重置)
+4. 深夜: MiniMax(5h 滚动)或 iFlow(免费)
+

+| `claude-opus-4-5` | Anthropic | Claude Opus 4.5 |
+| `claude-sonnet-4-5` | Anthropic | Claude Sonnet 4.5 |
+| `gemini-2.0-flash` | Google | Gemini 2.0 Flash |
+
+## 使用
+
+### 聊天界面
+
+1. 打开 Cursor 聊天(Cmd/Ctrl + L)
+2. 从下拉菜单中选择模型
+3. 通过 9Router 与 AI 对话
+
+### 内联代码生成
+
+1. 在编辑器中选中代码
+2. 按 Cmd/Ctrl + K
+3. 输入 prompt
+4. Cursor 会通过 9Router 生成代码
+
+### 代码解释
+
+1. 在编辑器中选中代码
+2. 按 Cmd/Ctrl + L
+3. 询问 "Explain this code"
+4. 通过 9Router 获得 AI 驱动的解释
+
+## 故障排除
+
+### "Invalid API Key" 错误
+
+1. 在 9Router 仪表盘中确认 API key
+2. 确保复制了包含 `sk-9router-` 前缀在内的完整 key
+3. 检查 API key 是否过期
+4. 尝试重新生成 API key
+
+### "Model Not Found" 错误
+
+1. 确认模型名与 9Router 配置完全一致
+2. 检查 9Router 仪表盘中提供商连接是否激活
+3. 确认连接的提供商中包含该模型
+4. 尝试使用完整模型名(例如用 `openai/gpt-4` 代替 `gpt-4`)
+
+### 连接问题
+
+1. 确认使用的是云端 endpoint:`https://9router.com`
+2. 检查网络连接
+3. 确认 9Router 云端服务运行正常
+4. 若启用了 VPN 或代理,尝试关闭
+
+### Localhost 无法使用
+
+> **请记住**:Cursor 不支持 localhost endpoint。你必须使用云端 endpoint `https://9router.com`。如果需要使用本地 9Router 实例,可以考虑使用 ngrok 之类的隧道服务把本地 endpoint 暴露到公网。
+
+## 云端 Endpoint 设置
+
+如果你在本地运行 9Router 并希望搭配 Cursor 使用:
+
+1. 在 9Router 设置中启用云端 endpoint
+2. 在 9Router 仪表盘中配置云端 endpoint URL
+3. 在 Cursor 设置中使用该云端 URL
+4. 确保本地 9Router 实例可从互联网访问
+
+## 最佳实践
+
+1. **使用模型别名**:为常用模型在 9Router 中创建简短别名
+2. **监控使用**:在 9Router 仪表盘查看用量统计和成本
+3. **轮换 API Keys**:为安全起见定期轮换 API key
+4. **测试模型**:尝试不同模型,找到最适合你场景的那个

+## 使用示例
+
+### Cursor IDE 设置
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [从 9router 仪表盘获取]
+  Model: glm/glm-4.7
+```
+
+### 创建组合(推荐)
+
+```
+仪表盘 → 组合 → 新建
+
+名称: cheap-backup
+模型:
+  1. cc/claude-opus-4-5 (订阅主力)
+  2. glm/glm-4.7 (低价备用, 每日重置)
+  3. minimax/MiniMax-M2.1 (最便宜的回退)
+  4. if/kimi-k2-thinking (免费应急)
+
+CLI 中使用: cheap-backup
+```
+
+**结果:** 订阅 → 低价 → 最便宜 → 免费
+
+---
+
+## 成本优化
+
+### 策略 1:每日重置例程
+
+```
+早上(10AM): 全新 GLM 配额
+→ 用 GLM 处理重任务
+→ 节省订阅配额
+
+下午: 订阅配额
+→ 用 Claude/Codex 处理复杂任务
+
+晚上: MiniMax(5h 重置)
+→ 深夜的低价备用
+
+夜里: 免费层(iFlow)
+→ 零成本应急备用
+```
+
+### 策略 2:预算优先
+
+```
+设置月预算: $20
+
+分配:
+- $9 Kimi K2(10M tokens 固定)
+- $6 GLM 每日配额(10M tokens)
+- $5 MiniMax 溢出(25M tokens)
+
+合计: $20 拿到 45M tokens
+而 ChatGPT API 同样的钱只能拿 1M tokens!
+```
+
+### 策略 3:订阅优先最大化
+
+```
+优先级:
+1. Gemini CLI(每月免费 180K)
+2. Claude Code(已付费订阅)
+3. GLM-4.7(低价备用,每 1M $0.6)
+4. MiniMax M2.1(最便宜,每 1M $0.2)
+5. iFlow(免费应急)
+
+月成本示例(100M tokens):
+- 60M 通过 Gemini CLI: $0(免费)
+- 30M 通过 Claude Code: $0(订阅)
+- 8M 通过 GLM: $4.80
+- 2M 通过 MiniMax: $0.40
+合计: $5.20/月!
+```
+
+---
+
+## 真实案例
+
+### 案例 1:重度编码月(100M tokens)
+
+```
+分解:
+- 60M 通过订阅(Claude/Codex): 无额外费用
+- 30M 通过 GLM-4.7: $18
+- 10M 通过 MiniMax M2.1: $2
+
+合计: $20/月
+而 ChatGPT API 需 $2000!
+
+节省: 便宜 99%!
+```
+
+### 案例 2:预算编码者($10/月)
+
+```
+策略:
+- $9 Kimi K2(10M tokens)
+- $1 MiniMax 溢出(5M tokens)
+
+合计: $10 拿到 15M tokens
+而 ChatGPT API 同样的钱只能拿 0.5M tokens!
+
+多 30 倍 tokens!
+```
+
+### 案例 3:自由职业(用量浮动)
+
+```
+清淡月(20M tokens):
+- 15M 通过订阅: $0
+- 5M 通过 GLM: $3
+合计: $3
+
+繁忙月(150M tokens):
+- 60M 通过订阅: $0
+- 60M 通过 GLM: $36
+- 30M 通过 MiniMax: $6
+合计: $42
+
+平均: $22.50/月
+而 ChatGPT API 需 $3400!
+```
+
+---
+
+## 最佳实践
+
+### 1. 跟踪每日配额
+
+```
+仪表盘显示:
+- GLM 配额: 已用 75%(6h 后重置)
+- MiniMax 配额: 已用 50%(2h 后重置)
+- Kimi 配额: 已用 8M/10M(15 天后重置)
+
+围绕重置时间规划重任务!
+```
+
+### 2. 使用 Coding Plan(GLM)
+
+```
+标准: 1× 配额
+Coding Plan: 3× 配额(同价!)
+
+→ 永远选 Coding Plan
+```
+
+### 3. 结合免费层
+
+```
+组合:
+1. gc/gemini-3-flash(免费主力)
+2. glm/glm-4.7(低价备用)
+3. minimax/MiniMax-M2.1(最便宜)
+4. if/kimi-k2-thinking(免费应急)
+
+结果: 最小化成本,最大化在线
+```
+
+### 4. 设置预算告警
+
+```
+仪表盘 → 设置 → 预算告警
+
+每日: $2 上限
+每周: $10 上限
+每月: $30 上限
+
+→ 达到上限时自动切换到免费层
+```
+
+---
+
+## 故障排除
+
+### "Quota exhausted"
+
+**方案:**
+- GLM: 等到北京时间 10:00 AM
+- MiniMax: 从首次使用起等 5 小时
+- Kimi: 等到下月 1 日
+- 使用组合回退到免费层
+
+### "API key invalid"
+
+**方案:**
+- 检查 API key 是否复制正确
+- 确认账户有余额
+- 必要时重新生成 API key
+
+### "High costs"
+
+**方案:**
+- 在仪表盘查看使用统计
+- 设置预算告警
+- 切换到 MiniMax(每 1M $0.2 最便宜)
+- 非关键任务用免费层
+

+## 使用示例
+
+### Cursor IDE 设置
+
+```
+Settings → Models → Advanced:
+  OpenAI API Base URL: http://localhost:20128/v1
+  OpenAI API Key: [从 9router 仪表盘获取]
+  Model: cc/claude-opus-4-5-20251101
+```
+
+### 创建组合(推荐)
+
+```
+仪表盘 → 组合 → 新建
+
+名称: premium-coding
+模型:
+  1. gc/gemini-3-flash-preview (免费, 优先使用)
+  2. cc/claude-opus-4-5-20251101 (订阅)
+  3. cx/gpt-5.2-codex (订阅备用)
+
+CLI 中使用: premium-coding
+```
+
+**结果:** 最大化免费层 → 使用订阅 → 自动回退
+
+---
+
+## 配额跟踪
+
+9Router 实时跟踪配额:
+
+- **Token 消耗** - 每次请求的输入/输出 tokens
+- **重置倒计时** - 下次配额重置剩余时间
+- **使用百分比** - 配额已用比例
+- **自动回退** - 耗尽时切换到下一层
+
+**仪表盘视图:**
+
+```
+Claude Code Pro
+├─ 配额: 已用 75%
+├─ 重置: 2h 15m(5 小时)
+├─ 每周重置: 3 天
+└─ 回退: glm/glm-4.7(低价层)
+```
+
+---
+
+## 最佳实践
+
+### 1. 优先使用免费层
+
+```
+优先级:
+1. Gemini CLI(每月免费 180K)
+2. Antigravity(免费 Claude)
+3. Claude Code/Codex(付费订阅)
+```
+
+### 2. 每日跟踪配额
+
+- 每天早上查看仪表盘
+- 围绕配额重置规划重任务
+- 非关键任务用低价/免费层
+
+### 3. 创建智能组合
+
+```
+示例组合:
+1. gc/gemini-3-flash-preview(免费主力)
+2. cc/claude-opus-4-5(复杂任务)
+3. glm/glm-4.7(低价备用)
+4. if/kimi-k2-thinking(免费回退)
+```
+
+### 4. 按时间优化
+
+```
+早上: 全新 5 小时配额(Claude/Codex)
+下午: Gemini CLI(每日 1K)
+晚上: 订阅配额
+深夜: 低价/免费层
+```
+
+---
+
+## 故障排除
+
+### "Quota exhausted"
+
+**方案:**
+- 查看仪表盘配额跟踪
+- 等待重置(5 小时或每日)
+- 使用组合回退到低价/免费层
+
+### "OAuth token expired"
+
+**方案:**
+- 9Router 会自动刷新
+- 若仍有问题: 仪表盘 → 提供商 → 重新连接
+
+### "Rate limiting"
+
+**方案:**
+- 订阅配额已用尽
+- 添加回退:`cc/claude-opus → glm/glm-4.7`
+- 使用免费层:`if/kimi-k2-thinking`
+
+---
+
+## 下一步
+
+- **设置低价备用:** [低价提供商](./cheap.md)
+- **添加免费回退:** [免费提供商](./free.md)
+- **创建组合:** 仪表盘 → 组合 → 新建

+# 故障排除
+
+使用 9Router 时常见的问题与解决方案。
+
+---
+
+## "Language model did not provide messages"
+
+**问题:** 请求失败,响应为空或返回错误。
+
+**原因:**
+- 提供商配额耗尽
+- API key 无效或过期
+- 模型不可用
+
+**解决方案:**
+
+1. **查看配额状态:**
+   ```
+   仪表盘 → 提供商 → 查看配额跟踪
+   ```
+   若配额耗尽,等待重置或切换提供商。
+
+2. **使用组合回退:**
+   ```
+   仪表盘 → 组合 → 创建回退链
+   示例: cc/claude-opus → glm/glm-4.7 → if/kimi-k2
+   ```
+
+3. **验证提供商连接:**
+   ```
+   仪表盘 → 提供商 → 必要时重新连接
+   ```
+
+---
+
+## 速率限制
+
+**问题:** 出现 "Rate limit exceeded" 或 "Too many requests" 错误。
+
+**原因:**
+- 订阅配额用完(5 小时/每日/每周限制)
+- 触发了 API 速率限制
+- 并发请求过多
+
+**解决方案:**
+
+1. **查看重置时间:**
+   ```
+   仪表盘 → 配额跟踪 → 查看重置倒计时
+   ```
+
+2. **切换到低价层:**
+   ```
+   使用: glm/glm-4.7 (每 1M tokens $0.6)
+        minimax/MiniMax-M2.1 (每 1M tokens $0.20)
+   ```
+
+3. **添加回退组合:**
+   ```
+   仪表盘 → 组合 → 添加备用模型
+   主力: cc/claude-opus (订阅)
+   备用: glm/glm-4.7 (低价)
+   应急: if/kimi-k2 (免费)
+   ```
+
+---
+
+## OAuth Token 过期
+
+**问题:** 出现 "Unauthorized" 或 "Token expired" 错误。
+
+**原因:**
+- OAuth token 过期(自动刷新失败)
+- 提供商会话失效
+- 刷新过程中出现网络问题
+
+**解决方案:**
+
+1. **自动刷新(默认):**
+   9Router 会自动刷新 token。等待 30 秒后重试。
+
+2. **手动重连:**
+   ```
+   仪表盘 → 提供商 → [提供商名称] → 重新连接
+   → 再次完成 OAuth 流程
+   ```
+
+3. **检查提供商状态:**
+   确认提供商服务在线(Claude Code、Codex 等)。
+
+---
+
+## 成本过高
+
+**问题:** 出现意外的高用量或高成本。
+
+**原因:**
+- 不必要地使用了昂贵模型
+- 没有回退到便宜层级
+- 上下文窗口过大
+
+**解决方案:**
+
+1. **查看使用统计:**
+   ```
+   仪表盘 → 使用统计 → 查看 token 消耗
+   → 找出高成本模型
+   ```
+
+2. **切换到更便宜的模型:**
+   ```
+   替换: cc/claude-opus ($20-100/月 订阅)
+   为: glm/glm-4.7 (每 1M tokens $0.6)
+       minimax/MiniMax-M2.1 (每 1M tokens $0.20)
+   ```
+
+3. **使用免费层:**
+   ```
+   if/kimi-k2-thinking (免费)
+   qw/qwen3-coder-plus (免费)
+   kr/claude-sonnet-4.5 (免费)
+   gc/gemini-3-flash-preview (每月免费 180K)
+   ```
+
+4. **优化 prompt:**
+   - 减少上下文大小
+   - 长响应使用流式输出
+   - 缓存常用 prompt
+
+---
+
+## 连接被拒绝
+
+**问题:** 出现 "ECONNREFUSED" 或 "Cannot connect to localhost:20128"。
+
+**原因:**
+- 9Router 未运行
+- 端口 20128 被阻止
+- 防火墙拦截连接
+
+**解决方案:**
+
+1. **启动 9Router:**
+   ```bash
+   9router
+   ```
+   仪表盘应该在 http://localhost:3000 打开。
+
+2. **检查端口 20128:**
+   ```bash
+   # 检查端口是否监听
+   lsof -i :20128
+   
+   # Windows
+   netstat -ano | findstr :20128
+   ```
+
+3. **检查防火墙:**
+   - macOS: 系统设置 → 网络 → 防火墙
+   - Windows: Windows Defender 防火墙 → 允许应用
+   - Linux: `sudo ufw allow 20128`
+
+4. **使用云端 endpoint:**
+   如果 localhost 不行(例如 Cursor IDE):
+   ```
+   Endpoint: https://9router.com/v1
+   ```
+
+---
+
+## 仪表盘无法打开
+
+**问题:** 仪表盘无法在 http://localhost:3000 加载。
+
+**原因:**
+- 端口 3000 被占用
+- 9Router 崩溃
+- 浏览器缓存问题
+
+**解决方案:**
+
+1. **确认 9Router 是否运行:**
+   ```bash
+   # 检查进程
+   ps aux | grep 9router
+   
+   # 检查端口 3000
+   lsof -i :3000
+   ```
+
+2. **杀掉冲突进程:**
+   ```bash
+   # macOS/Linux
+   lsof -ti:3000 | xargs kill -9
+   
+   # Windows
+   netstat -ano | findstr :3000
+   taskkill /PID <PID> /F
+   ```
+
+3. **重启 9Router:**
+   ```bash
+   # 停止
+   pkill -f 9router
+   
+   # 启动
+   9router
+   ```
+
+4. **清除浏览器缓存:**
+   - Chrome: Ctrl+Shift+Delete → 清除缓存
+   - 尝试无痕模式
+
+5. **检查防火墙设置:**
+   确认端口 3000 未被阻止。
+
+---
+
+## 模型未找到
+
+**问题:** 出现 "Model not found" 或 "Invalid model" 错误。
+
+**原因:**
+- 提供商未连接
+- 模型 ID 拼写错误
+- 提供商未激活
+
+**解决方案:**
+
+1. **验证提供商连接:**
+   ```
+   仪表盘 → 提供商 → 检查状态(绿色 = 已激活)
+   ```
+
+2. **检查模型 ID 格式:**
+   ```
+   正确: cc/claude-opus-4-5-20251101
+   错误: claude-opus-4-5-20251101
+   
+   格式: [provider-prefix]/[model-name]
+   ```
+
+3. **列出可用模型:**
+   ```bash
+   curl http://localhost:20128/v1/models \
+     -H "Authorization: Bearer your-api-key"
+   ```
+
+4. **重新连接提供商:**
+   ```
+   仪表盘 → 提供商 → [提供商] → 重新连接
+   ```
+
+---
+
+## 响应缓慢
+
+**问题:** 请求耗时过长或超时。
+
+**原因:**
+- 提供商延迟
+- 网络问题
+- 上下文/响应过大
+- 提供商速率限制
+
+**解决方案:**
+
+1. **查看提供商状态:**
+   ```
+   仪表盘 → 提供商 → 查看延迟统计
+   ```
+
+2. **切换到更快的模型:**
+   ```
+   快速: cc/claude-haiku-4-5 (Haiku 比 Opus 快)
+         gc/gemini-3-flash-preview
+         qw/qwen3-coder-flash
+   ```
+
+3. **使用流式响应:**
+   ```json
+   {
+     "model": "cc/claude-opus-4-5",
+     "messages": [...],
+     "stream": true
+   }
+   ```
+
+4. **检查网络:**
+   ```bash
+   # 测试延迟
+   ping api.anthropic.com
+   ping api.openai.com
+   ```
+
+5. **减小上下文:**
+   - 精简消息历史
+   - 使用更短的 prompt
+   - 在 CLI 工具中启用上下文裁剪
+
+---
+
+## API Key 无效
+
+**问题:** 出现 "Invalid API key" 或 "Authentication failed" 错误。
+
+**原因:**
+- 复制了错误的 API key
+- API key 已过期
+- 未生成 API key
+
+**解决方案:**
+
+1. **重新生成 API key:**
+   ```
+   仪表盘 → 设置 → API Keys → 生成新 Key
+   → 复制并使用新 key
+   ```
+
+2. **检查 key 格式:**
+   ```
+   正确: 9r_xxxxxxxxxxxxxxxxxxxxxxxx
+   错误: 缺少 9r_ 前缀
+   ```
+
+3. **检查 CLI 配置中的 key:**
+   ```bash
+   # Cursor
+   Settings → Models → OpenAI API Key
+   
+   # Cline
+   Settings → API Key
+   
+   # 环境变量
+   export OPENAI_API_KEY="9r_your_key"
+   ```
+
+4. **测试 API key:**
+   ```bash
+   curl http://localhost:20128/v1/models \
+     -H "Authorization: Bearer 9r_your_key"
+   ```
