OpenAI Deprecations
OpenAI publishes deprecation dates and recommended replacements on its API deprecations page. Use this page as a migration checklist, then validate the replacement against your production prompts, tools, latency, and cost envelope.Model deprecations
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
- Replace the deprecated model or product in a staging environment.
- Re-run representative evaluations, especially structured outputs, tool calls, audio quality, and long-context tasks.
- Compare latency and spend under production-like concurrency.
- Canary the replacement with an explicit rollback route before the shutdown date.
