⚡ OpenAI Ultrafast Puts Frontier AI in the Fast Lane

NewBits Digest feature image for an article on OpenAI Ultrafast, highlighting Cerebras-powered high-speed inference for GPT-5.6 Sol.

OpenAI has previewed Ultrafast, a Cerebras-powered API tier that runs its flagship GPT-5.6 Sol model at up to 14 times normal speed, reaching as much as 750 output tokens per second. The model did not get smaller, simpler or less intelligent. It simply stopped dawdling.


The partnership was announced in January, with Cerebras expected to provide OpenAI with 750 megawatts of high-speed AI inference capacity. In Cerebras testing, OpenAI Ultrafast completed Humanity’s Last Exam’s 2,500 questions in just over 11 hours, compared with more than 78 hours for Claude Fable 5, while achieving comparable accuracy.


One OpenAI employee described the experience as “genuinely cheating at my job.” Another demonstration showed investigation workflows that previously took one to two hours shrinking to roughly 10 to 15 minutes.


For now, OpenAI Ultrafast remains a limited, invitation-only API preview, and OpenAI has not announced pricing. Access is expected to expand as additional Cerebras capacity comes online.


⭐ Why OpenAI Ultrafast Matters


For years, artificial intelligence forced a choice: intelligence or speed. OpenAI Ultrafast suggests that choice may be disappearing.


When powerful AI can research, reason, code and act almost as quickly as we can think, it stops feeling like a tool waiting for instructions and starts behaving like a collaborator already halfway through the job.


The unanswered question is cost. Speed has always been available to those willing to pay for it. The revolution begins when everyone else can afford the ticket.
