What stops working?

24 models are due to be retired in the next 30 days.

96retirements published by OpenAI, Anthropic and Google. 68 carry a firm date; the rest are floors — "not before" a date.

A firm date is the day the provider named. not before means they have committed only that it will not happen sooner — the model may never be retired at all. Every row links to the provider's own page; check there before you act.
