OpenAI Retires Evals Platform
- "On June 3, 2026, we notified developers using the Evals platform that the product is being deprecated"[1]
- The shutdown comes in two steps: on Oct 31, 2026 "Existing evals become read-only", and on Nov 30, 2026 "The Evals dashboard and API are scheduled to shut down"[1]
- "Graders documented for eval workflows are part of this transition. Fine-tuning-related timelines remain covered in the self-serve fine-tuning section"[1]
- The page points to "Moving from OpenAI Evals to Promptfoo" as a migration path[1]
- Two other products announced the same day, 3 June 2026, share the 30 November 2026 shutdown: reusable prompts (the v1/prompts API) and Agent Builder[1]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
