OpenAI set to open Ultrafast API to more users, real-time computer use in sight
Angaisb_ · x · 2026-09-26
Leaked details suggest OpenAI will expand its Ultrafast API to more users after DevDay, adding a Speed selector (Fast / Standard / Ultrafast) to the Responses API Playground. The Ultrafast model was previously limited to select partners.
A $500 ChatGPT Pro Max plan promising the "fastest" responses was also spotted, signaling OpenAI is heavily investing in inference infrastructure — potentially enabling real-time computer use agents if pricing allows.
