## Notice policy

180+ day minimum. At least 6 months’ notice before retirement for generally available models, unless safety or compliance concerns require a faster timeline

OpenAI does not commit to publishing forward-looking retirement dates ahead of the notice window.

## FAQ

### Which OpenAI models are deprecated or being retired?

As of Oct 15, 2026, OpenAI has 118 upcoming dated retirements and 107 past across its first-party API and the partner routes in the feed. The next is ft-babbage-002 on the first-party API on Oct 23, 2026. The soonest dated rows: ft-babbage-002 on the first-party API on Oct 23, 2026; ft-davinci-002 on the first-party API on Oct 23, 2026; ft-gpt-3.5-turbo on the first-party API on Oct 23, 2026. Every row in the tables above carries its own source receipt.

### When is the next OpenAI model retirement?

ft-babbage-002 on the first-party API on Oct 23, 2026, as published in the source linked on that row. Dates marked "no sooner than" are floors, not deadlines.

### How much notice does OpenAI give before retiring a model?

OpenAI states at least 180 days’ notice before retirement: “At least 6 months’ notice before retirement for generally available models, unless safety or compliance concerns require a faster timeline.”

### 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.
