How to Use 627+ AI Models in Cursor IDE with Crazyrouter (2026 Guide)

#ai #cursor #coding #tutorial

Cursor IDE is powerful, but it only supports a few built-in models. Here's how to unlock 627+ models — including GPT-5, Claude Opus 4.6, DeepSeek R1, Gemini 3, and more — through Crazyrouter.

Why Use Crazyrouter with Cursor?

  • Access models Cursor doesn't natively support (DeepSeek, Qwen3, Llama 4, Grok 4)
  • Save money — Crazyrouter pricing is often lower than direct API pricing
  • Switch between models without changing IDE settings
  • One API key for everything

Setup (3 Minutes)

Step 1: Get a Crazyrouter API Key

  1. Go to crazyrouter.com
  2. Sign up — you get $0.20 free credit immediately
  3. Go to crazyrouter.com/token to generate your API key

Step 2: Configure Cursor

  1. Open Cursor → Settings (⌘/Ctrl + ,)
  2. Go to Models section
  3. Click Add Model or OpenAI API Key
  4. Set:
    • API Key: Your Crazyrouter key
    • Base URL: https://crazyrouter.com/v1
  5. Add model names you want to use:
    • gpt-5
    • claude-sonnet-4-6
    • deepseek-v3.2
    • gemini-2.5-pro
    • llama-4-maverick

Step 3: Use Any Model

In the Cursor chat or inline edit, select your model from the dropdown. All 627+ models are available.

Best Models for Coding in Cursor

Task Recommended Model Why
General coding gpt-5 Best all-around
Complex refactoring claude-opus-4-6 Deep reasoning
Quick fixes gpt-5-mini Fast and cheap
Code review claude-sonnet-4-6 Thorough analysis
Budget coding deepseek-v3.2 90% quality, 30% cost
Large context gemini-2.5-pro 1M token context

Cost Comparison (Per 1M Tokens)

Model Direct Price Via Crazyrouter
GPT-5 $1.25 / $10.00 Lower
Claude Sonnet 4.6 $3.00 / $15.00 Lower
DeepSeek V3.2 $0.27 / $1.10 Lower

Check exact prices at crazyrouter.com/pricing.

Pro Tips

1. Use environment variables (zero-config)

export OPENAI_API_KEY=your-crazyrouter-key
export OPENAI_BASE_URL=https://crazyrouter.com/v1
Enter fullscreen mode Exit fullscreen mode

Many tools (including Cursor) auto-detect these.

2. Mix models per task
Use gpt-5-mini for autocomplete (cheap, fast) and claude-opus-4-6 for complex refactoring (thorough, smart).

3. Try DeepSeek for budget coding
DeepSeek V3.2 is ~80% cheaper than GPT-5 and handles most coding tasks well. Great for prototyping.

Also Works With

This same setup works with:

  • VS Code + Continue extension
  • Windsurf IDE
  • Claude Code CLI (use Anthropic base URL: https://crazyrouter.com)
  • Codex CLI (set OPENAI_BASE_URL)
  • Aider (set OPENAI_API_BASE)

Troubleshooting

"Model not found" error: Check the exact model name at crazyrouter.com/pricing. Names are case-sensitive.

Slow responses: Try a different model. Some smaller models (gpt-5-mini, deepseek-v3.2) respond faster.

Rate limits: Crazyrouter handles rate limiting across providers. If you hit limits, it auto-routes to backup providers.
