# OpenAI Previews Ultrafast Mode for GPT-5.6 Sol: 14x Faster Processing Speed

> OpenAI and Cerebras Systems have unveiled Ultrafast, a new API tier that runs GPT-5.6 Sol at roughly 750 output tokens per second, about 14 times the speed of the standard mode. It is in limited preview only, with no pricing and no general availability date yet, so for now it is a demonstration of what the model can do when the hardware underneath it is built for raw throughput. The engine here is Cerebras, whose wafer-scale chips are designed to spit out tokens far faster than conventional GPU clusters. This tier is part of a broader OpenAI-Cerebras arrangement, a deal for 750 megawatts of compute capacity running through 2028 and valued at more than 10 billion dollars. Speed is quietly becoming its own frontier. As agents chain dozens of model calls together, latency compounds, and a 14x jump changes what feels possible in real time, from live coding to voice to interactive tools. It also signals that OpenAI is willing to look beyond Nvidia for the silicon that powers its fastest offerings.
