Same GPT-4o name, different shutdown dates: which version does your app use?
3-line summary
- October 23, 2026 is the scheduled shutdown date for a group of older OpenAI API models.
- GPT-4o versions have different deadlines, making the exact model ID important.
- Official model lookup documentation exposes an optional shutdown_date field.
OpenAI’s deprecation schedule assigns October 23, 2026 to API models including gpt-4o-2024-05-13 and gpt-4-0613. The timetable was announced on April 22. It concerns specific older models, rather than a simultaneous end for every GPT-4 variant.
The same schedule puts gpt-4o-2024-08-06 and gpt-4o-2024-11-20 on January 14, 2027. The GPT-4o model page describes snapshots as names that pin a particular version. A broad product name and the version an application specifies are different things.
Model list and retrieval references define shutdown_date as an optional date or null. Null means no shutdown date has been announced, not perpetual availability. The deprecation page also distinguishes advance notice from actual loss of access. This report checks the published schedule; it did not test shutdown times or account availability through API calls.
Why it matters
AI Ping sees exact model versions as part of routine operations. Replacing a model should include checks of the application’s inputs, tools and output formats alongside the name change.
Who it's for
- Developers
- Compare configured model IDs with those used in requests, then review the relevant deadlines and replacement candidates.
