Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. The error indicates that your API key is invalid.

Please check and share:

  • Are you trying to use your own xAI/Grok API key?
  • Do you have a custom OpenAI API key or an overridden OpenAI base URL enabled in Cursor Settings > Models > API Keys?
  • What is your current Cursor plan (Free/Pro/Business)?

Let me know what you have enabled and whether adjusting these settings helps.

  1. no
  2. actually yes, but grok was working one minute and then not the next, without me changing this key.
  3. pro

Grok is not from openai though right? i thought its xai.
so disabling openai keys has got this model working …
