Hosted Evals freeze today, gone Nov 30
OpenAI's Evals dashboard and API go read-only on Oct 31 and shut down entirely Nov 30. Export your datasets and graders now while you still can — OpenAI's own deprecation notice routes the migration to Promptfoo.
Agent Builder is sunsetting — move to the Agents SDK
Agent Builder shuts down Nov 30. ChatKit stays live, but any ChatKit frontend wired to an Agent Builder workflow ID stops working that day. OpenAI points builders to the Agents SDK or ChatGPT Workspace Agents.
The v1/prompts API dies — inline your reusable prompts
Reusable prompt objects and the v1/prompts endpoint shut down Nov 30. If your app fetches prompts by ID at runtime, move that content into your own codebase before the endpoint goes dark.
Kimi K2 reportedly closes to new signups
From Oct 31, Moonshot's Kimi K2 models are reportedly unavailable to newly registered users, with the full K2 series slated to retire by the end of December. Start new projects on K3.1 Pro instead.
