# OpenAI Deprecations

OpenAI publishes deprecation dates and recommended replacements on its [API deprecations page](https://developers.openai.com/api/docs/deprecations). Use this page as a migration checklist, then validate the replacement against your production prompts, tools, latency, and cost envelope.

## Model deprecations

| Deprecated model family                                                         | Deprecation date | Shutdown date      | Recommended replacement                                                              |

The catalog records these lifecycle dates on the affected OpenAI model entries, including replacement model IDs where OpenAI provides one. The dates apply to the provider snapshots named by OpenAI; the catalog may expose those snapshots through a canonical model ID.

## Platform deprecations

OpenAI also lists product-level migrations that are not model records:

* Reusable prompts are scheduled to shut down on November 30, 2026. Move prompt content into application code.
* The Evals platform becomes read-only on October 31, 2026 and shuts down on November 30, 2026. OpenAI recommends migrating to Promptfoo.
* Agent Builder shuts down on November 30, 2026. Migrate to the Agents SDK or ChatGPT Workspace Agents.

## Migration checklist

1. Replace the deprecated model or product in a staging environment.
2. Re-run representative evaluations, especially structured outputs, tool calls, audio quality, and long-context tasks.
3. Compare latency and spend under production-like concurrency.
4. Canary the replacement with an explicit rollback route before the shutdown date.
