Hey, thanks for the report and the Request ID. We’ve confirmed this is a bug on our side.

When using BYOK, sending images in chat isn’t handled correctly, which is why you’re seeing the Unauthorized error. Text-only chats still work, as you noticed.

I’ve passed this on to the team. For now, the workaround is to use Cursor’s built-in models for chats with images instead of BYOK.

Let me know if you have any questions.
