OpenAI is preparing to expand its Ultrafast API to more users after OpenAI DevDay.

A new Speed selector with Fast, Standard, and Ultrafast modes is coming to the Responses API Playground on the OpenAI Platform.

Earlier, OpenAI announced the Ultrafast model on the APIs; however, it has been only available to selected partners.

Earlier, a new $500 ChatGPT Pro Max subscription plan offering "fastest" responses was spotted. OpenAI seems to be heavily doubling down on its new infrastructure this time.
