Deprecation notice: upcoming model shutdowns in 2026

This is an unprecendented massive list of models going away.

• ISSUE: gpt-4-turbo appears in the list, but it is an alias to gpt-4-turbo-2024-04-09 that does NOT appear. Clarification must be made if the destination model will be shut off.

gpt-4-1106-preview appears in the listing with a shutoff date of 2026-10-23, but it was already listed and shutoff 2026-03-26, along with gpt-4-0125-preview, and is no longer available on API.

It seems that the embeddings model has been removed from the listing. If in error, the deprecations page should acknowledge the error blasted by email. Embeddings should be long-life, with a year notice.

Alias pointers should be distinct in their deprecation listing. “This pointer to an actual model is also going away”. Currently it seems we are forced to merely assume the destination model is deprecated.

Here’s a truth table for programmatic use (without the truth absolutely verified due to ambiguities), with Python inline comments. I included the image and audio models from the newest announcement, previous to that is only chat models.

These seem to be aliases that will have no destination, or that were listed instead of the true model:

computer-use-preview, gpt-3.5-turbo, gpt-4, gpt-4-32k, gpt-4-turbo, gpt-4-turbo-preview, gpt-4-vision-preview, gpt-4.1-nano, gpt-4o-audio-preview, gpt-4o-mini-search-preview, gpt-4o-search-preview, o1, o1-mini, o1-preview, o1-pro, o3-deep-research, o3-mini, o4-mini, o4-mini-deep-research

Prominently: Killing gpt-3.5, gpt-4, and gpt-4-turbo lines completely, along with original gpt-4o, then cutting right into reasoning models like o4-mini. The only thing spared is o3.
