OpenAI launches Ultrafast mode for GPT‑5.6, delivering up to 14× speed
OpenAI’s Ultrafast tier runs GPT‑5.6 Sol up to 14× faster, generating 750 output tokens per second. The speed boost keeps full model intelligence, letting real‑time apps—incident response, finance, live support—avoid the usual trade‑off of using smaller models. Access starts via a preview in the OpenAI API.
