OpenAI: Deprecation of legacy models by September 28, 2026
In line with OpenAI's plan to improve reliability and simplify model selection, we are retiring several legacy models. These models are now hidden from the selection menus in the OpenAI app to prevent their use in new scenarios.
Action required by September 28, 2026. After this date, scenarios using the deprecated models will stop running. You can no longer create new scenarios or update existing modules to use these models.
What's changing?
- Starting today, a set of legacy OpenAI models are no longer available for selection in any new modules.
- Existing scenarios that use these deprecated models will continue to run without interruption until September 28, 2026.
- After this date, any scenarios still using the deprecated models will fail.
What you need to do
To ensure your scenarios continue to run after the deadline, you must update any OpenAI modules using a deprecated model to a recommended replacement before September 28, 2026.
