No status update yet. As soon as I have one, I’ll reply in this thread.

In the meantime, the options are the same:

1. Keep Google API Key enabled and pick a different Gemini model in the model selector, like Gemini 3.7 Flash. With your key it works as usual. This was confirmed in another thread: [BYOK Gemini Flash 3.8 Unauthorized User API key](https://forum.cursor.com/t/byok-gemini-flash-3-8-unauthorized-user-api-key/170464)
2. If you specifically need Gemini 3.8 Flash, turn off the Google API Key toggle in Cursor Settings \> Models, and the model will run on your Cursor plan.

Let me know if any of this doesn’t work.
