OpenAI deprecates prompt objects and Evals API by Nov 30, 2026

OpenAI is deprecating its reusable prompt objects and the v1/prompts API, with both set to shut down on November 30, 2026. The Evals dashboard and API will also become read-only on October 31, 2026, and shut down on November 30, 2026. Developers are advised to migrate prompt text into their application code, but an alternative approach involves using a prompt library and an API gateway to maintain existing calls without code changes.
