Gemini 2.5 models accidentally deprecated early by Google

Google accidentally deprecated its Gemini 2.5 Flash and Pro models early, causing widespread production outages for developers who rely on the models. The issue was resolved after about 30 minutes, with Google restoring access to the models. The incident highlights the risks of premature deprecation in AI API services.

Hi, we are using Gemini 2.5 flash in our critical workloads and we saw that the deprecation date is Oct 16, 2026. But now we are seeing this come up, “This model models/gemini-2.5-flash is no longer available. Please update your code to use a newer model for the latest features and improvements.” with a 404. Is anyone observing the same issue? This is not good. Anyone from google support, please resolve this issue.

After checking with python I get this: 404 NOT FOUND. {‘error’: {‘code’: 404, ‘message’: ‘This model models/gemini-2.5-flash is no longer available. Please update your code to use a newer model for the latest features and improvements.’, ‘status’: ‘NOT FOUND’}} On their website where they put up the depreciation https://ai.google.dev/gemini-api/docs/deprecations https://ai.google.dev/gemini-api/docs/deprecations they show this: Now what to do? EDIT: I selected the wrong one in the picture, but you get the idea EDIT 2: Okay seems to be working again Works here again since 10 seconds I suspected his disable wrong model.
