Deprecated LLM models
A deprecated model still works. That is exactly what makes it dangerous: nothing in your logs says anything is wrong until the shutdown date arrives. These 32 models have had their end announced — 32 of them with a date attached.
All deprecated models, soonest end first
Sorted by the date you have to act on: the announced shutdown date where there is one, otherwise the deprecation date. Models without any date are still deprecated — the provider just has not committed to when.

What "deprecated" actually means
Providers use the word consistently enough to rely on: a deprecated model is one they have announced they will stop serving. It keeps working in the meantime — usually for months — and then it does not.
Two dates matter, and they are not the same one. The deprecation date is when the provider announced the model is on its way out. The shutdown date (also called retirement or sunset) is when requests start failing. We record both, separately, and always show you the one that carries a deadline.
Some providers announce the first without committing to the second. Where that is the case we say so rather than guessing at a date — see the methodology for how we handle incomplete announcements.
