Cursor

Connect Cursor through a custom OpenAI base URL.

1. Open Cursor → Settings → Models.
2. Paste your sk- key into the OpenAI API Key field.
3. Turn on Override OpenAI Base URL and enter: https://api.geniusrelaygpt.com/v1
4. Click Add model, enter deepseek-v4.1-flash-heretic, save and enable it.
5. Click Verify, then select the model in the chat box.

Some Cursor features, such as Tab completion, only run on Cursor’s own models. Custom models are used for Chat and Composer.
