Documented steps
WARNING: OpenAI deprecating the v1/prompts API and 'reusable prompt' objects. Shutdown date Nov 30, 2026 (announced Jun 3, 2026) - after this, v1/prompts calls and prompt-object references fail.
Do NOT build new integrations on reusable prompts. Instead embed the prompt content directly in application code / request payload.
If migrating existing code: replace calls to the v1/prompts API (create/list/get/update prompt objects) with inline prompt content in the relevant API request.
If you referenced prompt objects by ID in requests (responses/completions), swap to the literal prompt string so behavior is unchanged before shutdown.
Official deprecation list: https://developers.openai.com/api/docs/deprecations ; migration guide: https://developers.openai.com/api/docs/guides/prompting/migrate-from-prompt-object
Related same-day deprecations also shutting down Nov 30, 2026: Agent Builder and the Evals Platform (graders/evals read-only from Oct 31) - plan migration for both if used.
Known gotchas
Silent breakage: agents that keep calling v1/prompts after Nov 30, 2026 will start returning errors with no prior per-request warning.
Evals platform becomes read-only Oct 31, 2026 before full shutdown Nov 30 - don't wait until the end to migrate evaluation workflows.
Reusable prompt content must live in your code; there is no API fallback after shutdown.
