Problem Description
OpenAI announced last week a new Responses API that contains the feature set of the Chat Completions API and replaces the Assistants API (the latter is now deprecated and will be sunseted mid-2026).
Azure already announced that they provide this API day one and considering OpenAI's position on the market, we can expect that it will become an industry standard as is the Chat Completions API today.
Desired Solution you'd like
Ability to connect OpenWebUI to AI products exposed through the Responses API to interact with them in OpenWebUI
Ability to expose assistants created in OpenWebUI through an API that follows the Responses API standard and specs.
A thread on X by one of the creators of the API talking about its making
