Deprecations

Every model retirement OpenAI, Anthropic and Google have published, in one dated list. 71 carry a firm date; the rest are floors.

A firm date is the day the provider named. not beforemeans they have committed only that it will not happen sooner — the model may never be retired at all. We keep the distinction because acting on it is the difference between a migration you must schedule and one you need not. Every row links to the provider's own page; check there before you act.
