"On June 3, 2026, we notified developers usingOpenAI's deprecations page records the retirement of reusable prompts in the dashboard andprompt objects and the v1/prompts API that reusable prompt objects are being deprecated" From that same day, 3 June 2026, "promptas announced on 3 June 2026, with the shutdown scheduled for 30 November 2026; prompt creation [was]was de-emphasized infrom the platform" On Nov 30, 2026 "The v1/prompts announcement date. A prompt object was prompt text stored on the platform and referenced by an ID such as pmpt_123 in an API request, optionally with a pinned version number and reusable prompt a variables map (for example customer_name and issue) filled in at call time. Those stored objects are scheduled to shut down" what stop resolving at shutdown. The migration pathstated replacement is not a new hosted service. OpenAI's migration guide tells developers to "move reusable prompt content copy the text into their own codebase, turn template variables into your application code", per typed function arguments (a builder function such as buildSupportPrompt), send the page's "Migrate from generated system and user messages through the Responses API input field instead of the prompt objects" guide field, with git review replacing platform versioning. Two other products announced on the same day, 3 June 2026, 2026 date share the 30 November shutdown. Existing Evals become read-only on 31 October 2026 shutdown:before the Evals platformdashboard and API close, with Promptfoo as the suggested route. Agent Builder Deprecation takes effect immediately on announcement, and every deprecated model or endpoint is given a shut down date; closes too, with the Agents SDK or ChatGPT Workspace Agents as the destinations; ChatKit stays available. An independent write-up dated 20 October 2026 points out gaps in the page uses "sunset" documentation: it does not say what requests return after shutdown, whether the prompt parameter will behave differently, or whether saved prompts can be bulk-exported. It advises copying prompt text out and "shut down" interchangeablysearching code for prompt IDs before the deadline.
