Cursor

Last updated: 2026-08-03; third-party tools can change at any time. If configuration fails, follow the latest official documentation.

Cursor is a desktop IDE with model selection and code completion. Review the Cursor API Keys documentation first: a custom API Key applies only to standard chat models, while features such as Tab Completion that depend on specialized models continue to use Cursor's built-in models.

Configuration steps

1. Open Cursor’s Settings and enter Models.
2. Enable Override OpenAI Base URL in API Keys.
3. Enter the values in the table below, then save your changes.

1. Select View All Models → Add Custom Model, enter the ID of a model that supports OpenAI Chat Completions, and enable it.
2. Switch to the model in the chat panel and send a read-only question to verify the connection.

Override OpenAI Base URL currently applies globally to models that use a custom key, and some models that use the Responses API may not work with third-party compatible endpoints. Disable the override when using Cursor's built-in models. If Verify or Agent requests still fail, use Cline, Roo Code, Kilo Code, or OpenCode, which explicitly support OpenAI-compatible providers, and follow the Cursor documentation and official support guidance.
