Cursor

Use Cursor with a custom OpenAI-compatible endpoint and route model requests through XycAi.

Connection values

Open Cursor Settings → Models, enable the OpenAI API, and enter:

API Key:  sk-xxxxxxxx
Base URL: https://cn.chatapi.app/v1
Model:    deepseek-v4-pro

Verify the connection

Save the settings, select the custom model in Chat, and send a short test prompt.

Troubleshooting

• Use the exact model name shown in the model square.
• For 401 errors, create a fresh key and check its group permissions.
