AI model deprecations: when Claude, GPT and Gemini models retire
A model disappears from an API on a date the vendor publishes; the same model usually vanishes from the chat app on its own schedule, which no vendor publishes. This page tracks the published part: every Anthropic, OpenAI and Google Gemini API model with a deprecation or retirement date, the recommended replacement and the notice rules, quoted from the vendors' deprecation pages. Where the consumer app is concerned, the honest answer is "Not confirmed".

What the vendor pages do and do not say
Do these dates apply to ChatGPT, Claude.ai and the Gemini app?
All dates are for the vendors' APIs. Anthropic's page applies to Anthropic-operated platforms (Claude API, AWS, Google Cloud managed by Anthropic, Microsoft Foundry); OpenAI's page lists API deprecations; Google's page covers the Gemini API. None of the three pages states when a model leaves the consumer app or what happens to existing chats.
What happens to my old chats when a model is retired?
Not confirmed. None of the three deprecation pages describes the consumer apps. The only published rule is for the API: Anthropic states that requests to retired models fail, and OpenAI and Google say the same for their endpoints. Whether an existing chat keeps its model, is moved to a replacement or stays readable is not stated on these pages.
How much notice do developers get?
Anthropic promises at least 60 days for publicly released models. OpenAI promises at least 6 months for generally available models, at least 3 months for specialized variants and as little as 2 weeks for preview models. Google calls its dates the earliest possible shutdown and says the exact date comes with advance notice.
