OpenAI's API deprecations page lists four older models, gpt-3.5-turbo-instruct, babbage-002, davinci-002 and gpt-3.5-turbo-1106, with a shutdown date of September 28, 2026. It names gpt-5.6-terra as the recommended replacement for all four. The section now sits under "Past deprecations". The paragraph above its table still says access "will be shut down".
What the page says
The section is headed "2025-09-26: Legacy GPT model snapshots". Each of its four table rows reads 2026-09-28 as the shutdown date and gpt-5.6-terra as the recommended replacement.
The paragraph above the table ends:
Access to these models will be shut down on the dates below.
The sentence before it says the models are being deprecated "over the next six to twelve months".
Directly below, the section headed "2025-09-26: Legacy GPT model snapshots (March 2026 shutdown)" is worded differently:
Access to these models was shut down on March 26, 2026.
The page defines a shutdown as the point after which a model or endpoint is no longer accessible. In the four-model section, no sentence says that point has been reached.
What the headings do and do not show
The page does not say what places a section under "Upcoming deprecations" or "Past deprecations". Under "Past deprecations", the section headed "2026-04-22: Legacy GPT model snapshots" carries the same "will be shut down" sentence and lists October 23, 2026, a date still ahead on October 2. Under "Upcoming deprecations", a section headed 2026-09-11 says gpt-5.4-cyber will be removed on October 1, 2026, a date that had passed.
Copies of the page saved on the morning of September 28, Arizona time, show the four-model section under "Upcoming deprecations". A copy saved the evening of September 30 and copies saved on October 1 and October 2 show it under "Past deprecations". Its wording and table are the same in all of them. By these copies, the move happened between the morning of September 28 and the evening of September 30; the September 30 time comes from the saved file's modification time.
If your code still uses these names
- The section names
gpt-5.6-terrafor all four but gives no migration steps. - That 2026-04-22 section's table of fine-tuned versions lists
ft-babbage-002andft-davinci-002with a shutdown date of October 23, 2026. The page does not say how those relate to the September 28 rows. - The page says developers may in some cases be able to provision dedicated capacity for continued access after a shutdown date, and points them to OpenAI's sales team. It does not say whether that applies to these four models.
What the page does not say
- When the section moved, or when its paragraph was last edited. The page shows no edit date.
- Why the paragraph still says "will be shut down", or whether the move to "Past deprecations" is meant to say the shutdown has happened.
- What a request to any of these four models returns today. No API call was made.
