Previewing Ultrafast mode: GPT-5.6 Sol at up to 14X the speed
Article image or reusable cover for OpenAI
OpenAI is launching a new service called Ultrafast that runs their GPT-5.6 Sol model up to 14 times faster than normal.
The service is powered by Cerebras technology and can produce up to 750 output tokens per second — tokens are small text pieces that the model generates. It is a preview, meaning a test version that OpenAI is showing before full launch.
