Hey, thanks for the report. I can see the screenshot with your model settings.

This is a known issue where custom models don’t show up in the model selector on v2.6.12. The team knows about it, and your report helps us prioritize it.

A couple of things to try for now:

1. Go to Cursor Settings > Models, remove gemini-2.5-pro from the manually added models list, then restart Cursor and add it again.
2. If that doesn’t work, try adding your Google API key again first, then add the model. The order might matter.

Let me know if either workaround helps.
