Frequently asked questions
How much notice does OpenAI give before retiring a model?
OpenAI states at least 180 days’ notice before retirement: “At least 6 months.”
What does a "no sooner than" date mean?
It’s a floor, not a deadline. Some providers publish only the earliest possible shutdown date for a model, with the final date to be confirmed later. Treat it as "this won’t happen before this date," not as the date itself.
What’s the difference between "Announced" and "First observed by Radar"?
"Announced" is the date the provider itself published the notice — it only appears on a row when the provider discloses one. "First observed by Radar" is Radar’s own collection timestamp, the date its pipeline first saw the source; it is never presented as the provider’s own announcement date.
Does this page cover OpenAI models hosted on partner platforms?
Yes. This page lists every dated retirement notice observed for OpenAI, spanning its own first-party API and every partner platform it ships on. Each row’s Route column shows which one a given date applies to.
