Cursor

Cursor lets you add an OpenAI-compatible model through its settings. Claudin.io plugs in via the OpenAI base URL override.

Setup

  1. Open Cursor → Settings → Models (or Cursor Settings → AI).
  2. Scroll to OpenAI API Key and expand the Override OpenAI Base URL option.

  3. Set:

    Field Value
    OpenAI API Key YOUR_API_KEY
    Base URL https://api.claudin.io/v1

  4. Under Models, add a custom model named claudinio and enable it.

  5. Disable the other default models if you want Cursor to use Claudin.io exclusively.

Cursor's own features

Cursor's agentic features work best with an OpenAI-compatible chat model. claudinio supports tool calls, so the Composer/Agent flows work. Some Cursor-proprietary features (Tab autocomplete, etc.) run on Cursor's own models and aren't routed through your provider override.

Verify

Open a chat in Cursor, select claudinio, and send a message. If you get a reply, you're set. If not, double-check the base URL ends in /v1 and the key is pasted without extra spaces.
