What changes: OpenAI has set October 23, 2026 as the shutdown date for API access to a set of older model snapshots.
What the official table says
"To improve reliability and make it easier for developers to choose the right models, we are deprecating a set of older OpenAI models. Access to these models will be shut down on the dates below. Shutdown date: October 23, 2026 | Model snapshot: gpt-3.5-turbo-0125, gpt-4-0613, gpt-4-1106-preview, gpt-4-turbo, gpt-4-turbo-2024-04-09, gpt-4.1-nano, gpt-4.1-nano-2025-04-14, gpt-4o-2024-05-13, gpt-image-1, o1-2024-12-17, o1-pro-2025-03-19, o3-mini-2025-01-31, ft-o4-mini-2025-04-16, o4-mini-2025-04-16"
The three facts
- What happened: OpenAI deprecated a set of older models and published the date on which access to them is shut down.
- What continues: until that date, access keeps working — the quoted line is about a shutdown, not an immediate block.
- Next date: October 23, 2026.
The full list
gpt-3.5-turbo-0125 · gpt-4-0613 · gpt-4-1106-preview · gpt-4-turbo · gpt-4-turbo-2024-04-09 · gpt-4.1-nano · gpt-4.1-nano-2025-04-14 · gpt-4o-2024-05-13 · gpt-image-1 · o1-2024-12-17 · o1-pro-2025-03-19 · o3-mini-2025-01-31 · ft-o4-mini-2025-04-16 · o4-mini-2025-04-16
The actionable line
If any automation of yours pins one of these snapshot names in code — and pinning a snapshot is good practice precisely to avoid surprises — October 23, 2026 is the day that pin becomes a problem. There is plenty of time: almost two months to test a replacement and swap the string.
A grep through your repository for the 14 names above is worth doing. It is the cheapest test of the month.
The honest caveat
The quoted line carries the date and the model names — and nothing else. It does not name an official replacement for any snapshot in this batch. Choosing the destination model is on you, by testing.

One honest note: there is no universal multiplier. The outcome depends on your industry, your ticket, and how much of your volume is urgent versus price-shopping. Anyone promising a fixed return is selling, not calculating.
