OpenAI "Assistants API" used by Resume Review is being sunset 2026-08-26 #500

Earlier this year, we shared our plan to deprecate the Assistants API once the Responses API reached feature parity. With the launch of Conversations, Responses is now at feature parity with Assistants.

We will be deprecating the Assistants API with a planned shutdown date of August 26, 2026 (next year). You will be able to use the Assistants API until that sunset date, but we will not be adding new features or model support to the API.

We recommend migrating your Assistants workloads to the Responses API, which provides a simpler, more powerful foundation for building. Read more in our migration guide.

Thanks for building with OpenAI. If you have questions about migrating models, please reach out on the OpenAI Developer Forum.
