OpenAI Launches 'Ultrafast' Mode to Run GPT-5.6 Sol 14x Faster
OpenAI has rolled out a preview feature called Ultrafast that lets its flagship GPT-5.6 Sol model respond up to 14 times faster than its standard configuration. The mode is designed for enterprise customers who need near-instant outputs for latency-sensitive applications, such as customer support bots, real-time coding assistants, or high-volume data processing pipelines.
Details on how the speed boost is achieved remain limited, but such gains typically come from a mix of optimized inference infrastructure, model distillation, or selective trimming of reasoning steps. OpenAI hasn't fully specified what tradeoffs, if any, enterprises should expect in output quality or cost per token.
The launch signals OpenAI's continued push to differentiate its enterprise offerings from rivals like Anthropic and Google, especially as speed becomes a competitive battleground alongside raw capability.
