Hey, this isn’t a bug, it’s expected behavior. Using your own API keys (BYOK), including OpenRouter, requires a Pro subscription. On the Free plan, only Auto mode is available.
More details in this thread: Cursor Free Plan: How to choose Gemini model with BYO API Key?
Options:
- Upgrade to Pro ($20/mo). Then OpenRouter and other BYOK keys will work.
- Stay on Free and use the built-in free models via Auto mode.
Let me know if you’ve got any questions.
