The Evals Platform, Agent Builder, and Reusable Prompts (v1/prompts) all share a November 30, 2026 shutdown, with Evals hitting read-only a month earlier (TheRouter.ai). This follows OpenAI's March 10 acquisition of Promptfoo (300K+ developers, 127 Fortune 500 companies), and OpenAI's own migration guidance points there. If your eval definitions, graders, or historical run baselines live only in a vendor dashboard, that's a hard export deadline about 14 weeks out. Use it as the forcing function to move evals into versioned repo files where they belong.
