OpenAI will shut down its Evals dashboard and API, and the /v1/prompts reusable prompt objects, on November 30

OpenAI's API deprecations page lists two features for shutdown on November 30, 2026:

• The Evals dashboard, the Evals API and graders for eval workflows. OpenAI tells users to migrate to Promptfoo, and points to the fine-tuning timeline for fine-tuning graders.
• The /v1/prompts endpoint and reusable prompt objects. OpenAI tells users to move prompt content into their application code and links a migration guide.
