# Cursor

> Configure a custom OpenAI API in Cursor

## Configure

1. Open **Cursor Settings → Models**.
2. Enable a custom OpenAI API key and enter `API_KEY`.
3. Set **Override OpenAI Base URL** to `https://api.bianxie.ai/v1`.
4. Add and enable an exact model ID from the live model page.
5. Select it in Chat or Agent.

Test with “Reply only with OK,” then ask Agent to read a file without editing it. For `401`, replace the key; for `404`, check `/v1`; for tool failures, use a tool-capable model and start a new chat.

<Note>Some proprietary Cursor features may remain tied to Cursor services. Availability in Chat, Agent, or completions depends on the installed Cursor version.</Note>
