oh hey i am now getting something similar with gemini-2.5-flash-image (nanobanana) - this just happened:
Trying to contact the model returned this error: { "error": { "code": 404, "message": "models/gemini-2.5-flash-image-preview is not found for API version v1beta, or is not supported for generateContent. Call ListModels to see the list of available models and their supported methods.", "status": "NOT_FOUND" } }
all my other gemini flash models appear to be working
