# OpenAI Introduces Ultrafast Mode: GPT-5.6 Sol Now Runs 14x Faster

> OpenAI has launched Ultrafast, a new mode that runs its GPT-5.6 Sol model at up to 750 output tokens per second, roughly 14 times its standard speed. The gain does not come from a smaller or weaker model but from where it runs. OpenAI is serving Ultrafast on hardware from Cerebras, whose wafer-scale chips keep an entire model on a single giant piece of silicon and avoid much of the memory shuttling that slows conventional GPUs. Speed changes what a model is useful for. At conversational latency a lot of waiting disappears, which matters most for jobs where a person or another system is blocked until the answer arrives. OpenAI is aiming Ultrafast at exactly those cases, citing incident response, customer service, financial analysis, and e-commerce. For now it is a limited preview for enterprise customers, with access widening as capacity grows, and Anthropic offers a comparable fast mode for Claude at somewhat lower speeds. The broader signal is that inference speed, not just raw intelligence, is becoming a competitive axis, and specialized chips are how the labs intend to win it.
