A hosted evaluation service for defining tests, running them against AI model outputs and analyzing results through a dashboard and API.

OpenAI plans to make existing Evals read-only on October 31, 2026, then close the Evals dashboard and API on November 30.

Sources and verification

Shutdown: This record covers the named hosted Evals platform and its dashboard-to-results workflow, not an individual grader or model endpoint. October 31 is the planned read-only transition; November 30 is the planned final closure. The open-source Evals repository and separate fine-tuning schedules are outside scope. Actual cessation and cutoff time zone are unverified. Official shutdown notice
Dates checked: Announced 3 Jun 2026 · Verified 1 Oct 2026
AI functionality: AI functionality source
Launch: The first public availability of the combined hosted dashboard and API is unverified. The October 6, 2025 changelog describes additions to existing Evals, not its original launch.
Location: United States · San Francisco. OpenAI’s May 7, 2025 Department of Energy submission gives a San Francisco address. This records the operator’s historical legal-contact city, not a product-team location, current-office assertion or service market. Existing Natural Earth city coordinates are retained at two-decimal precision. Location source
