Integrate 9Router with Continue extension to bring AI assistance directly into Visual Studio Code.

Prerequisites

• Visual Studio Code installed
• Continue extension installed from VSCode marketplace
• 9Router API key from dashboard
• 9Router running (local or cloud)

Configuration Steps

1. Open Continue Configuration

1. Open VSCode
2. Press Cmd+Shift+P (Mac) or Ctrl+Shift+P (Windows/Linux)
3. Type "Continue: Open Config" and select it
4. This opens ~/.continue/config.json

2. Add 9Router Model Configuration

Add the following configuration to your config.json:

Single Model Setup:

{
  "models": [
    {
      "title": "9Router - Claude Opus",
      "provider": "openai",
      "model": "cc/claude-opus-4-5-20251101",
      "apiKey": "your-api-key-from-dashboard",
      "apiBase": "http://localhost:20128/v1"
    }
  ]
}

Multiple Models Setup:

{
  "models": [
    {
      "title": "9Router - Claude Opus (Best)",
      "provider": "openai",
      "model": "cc/claude-opus-4-5-20251101",
      "apiKey": "your-api-key-from-dashboard",
      "apiBase": "http://localhost:20128/v1"

      "provider": "openai",
      "model": "cx/deepseek-chat",
      "apiKey": "your-api-key-from-dashboard",
      "apiBase": "http://localhost:20128/v1"
    },
    {
      "title": "9Router - Claude Haiku (Fast)",
      "provider": "openai",
      "model": "cc/claude-haiku-4-20250514",
      "apiKey": "your-api-key-from-dashboard",
      "apiBase": "http://localhost:20128/v1"
    }
  ]
}

For Cloud 9Router: Replace apiBase with:

"apiBase": "https://9router.com/v1"

    {
      "title": "9Router - Code Expert",
      "provider": "openai",
      "model": "cx/deepseek-chat",

    }
  ]
}

Temperature and Parameters

Adjust model behavior with parameters:

{
  "models": [
    {
      "title": "9Router - Creative Writer",
      "provider": "openai",
      "model": "cc/claude-opus-4-5-20251101",
      "apiKey": "your-api-key",
      "apiBase": "http://localhost:20128/v1",

  "contextProviders": [
    {
      "name": "code",
      "params": {
        "maxLines": 100
      }
    },

    }
  ]
}

Keyboard Shortcuts

• Cmd+L (Mac) / Ctrl+L (Windows/Linux) - Open Continue chat
• Cmd+I (Mac) / Ctrl+I (Windows/Linux) - Inline edit
• Cmd+Shift+R (Mac) / Ctrl+Shift+R (Windows/Linux) - Regenerate response

Troubleshooting

Model Not Responding

• Check 9Router is running: curl http://localhost:20128/health
• Verify API key in config.json
• Check VSCode Developer Console for errors: Help → Toggle Developer Tools

Wrong Model Selected

• Click model dropdown in Continue sidebar
• Select correct 9Router model
• Model name must match exactly (case-sensitive)

Configuration Not Loading

• Verify JSON syntax is valid (use JSON validator)
• Check file location: ~/.continue/config.json
• Reload VSCode window after changes

Slow Performance

• Switch to faster models (haiku, flash)
• Reduce context size in contextProviders
• Check network latency to 9Router

Best Practices

Model Selection Strategy

• Quick edits: Use cc/claude-haiku-4-20250514
• Code generation: Use cx/deepseek-chat
• Complex refactoring: Use cc/claude-opus-4-5-20251101
• Problem solving: Use cx/deepseek-reasoner

Context Management

• Select only relevant code before asking
• Use specific, clear prompts
• Break complex tasks into smaller steps

Cost Optimization

• Use faster/cheaper models for simple tasks
• Limit context size when possible
• Cache frequently used responses
