Use your own API keys to send unlimited AI messages at your own cost. When configured, Cursor will use your API keys to call LLM providers directly. To use your API key, go to Cursor Settings > Models and enter your API keys. Click Verify. Once validated, your API key is enabled.
Custom API keys only work with standard chat models. Features requiring specialized models (like Tab Completion) will continue using Cursor’s built-in models.
