gemini-1.0-pro shut down Oct 14, 2026 (Gemini API)

The error you get

What Gemini API answers a call to gemini-1.0-pro once the model is gone, as recorded from real responses:

Once it is closed to new API keys: HTTP 404

{"error":{"code":404,"message":"This model models/gemini-1.0-pro is no longer available to new users. Please update your code to use a newer model for the latest features and improvements.","status":"NOT_FOUND"}}

Once it is shut down: HTTP 404

{"error":{"code":404,"message":"models/gemini-1.0-pro is not found for API version v1beta, or is not supported for generateContent. Call ModelService.ListModels to see the list of available models and their supported methods.","status":"NOT_FOUND"}}

What to use instead of gemini-1.0-pro

gemini-2.5-pro, named first, is closed to some callers (Google: "we are limiting access to the 2.5 models to users who have actively used them in the past." Projects that already called it keep it; new projects are told to use 3.5 Flash-Lite or 3.8 Flash.). No replacement that holds is named yet. Nothing about a 1.0-era integration survives unchanged: the SDK, the request shape and the safety-setting enums have all been replaced since.
