Expose Model Deprecation Dates Through the API
OpenAI Developer Community
March 5, 2026
If you want programmatic use, such as displaying a warning in a UI along with selection or use of a particular model, this should keep you going for a while:
With gpt-4o being deprecated - what does that mean for gpt-4o fine tunes?
> Your code can also surface data from this Python dict I made;
> some fine-tunings have been allowed past official shutoff,
> other deprecation announcements haven’t made any distinction
> about their fine-tuning variants.
>
>
> DEPRECATIONS = {
> "gpt-3.5-turbo-instruct"
>
If you are actively using the models endpoint, unavailable models that are shut off will of course be unavailable.
