OpenAI and Cerebras Preview GPT-5.6 Sol Ultrafast Mode at 750 Tokens/s

OpenAI has officially previewed the new Ultrafast mode, designed specifically for the GPT-5.6 Sol model. By significantly boosting inference speeds, it aims to optimize time-sensitive business applications. Powered by Cerebras, this feature pushes the model's generation speed to new limits.

已确认

• 极致速度: The Ultrafast mode processes data up to 14 times faster than the standard mode, achieving a generation speed of 750 tokens per second.
• 算力支持: This mode is powered by underlying computing support from renowned chip company Cerebras, rather than being developed solely by OpenAI.
• 推出渠道: The service will initially roll out via the OpenAI API for developers to integrate and utilize.

为什么重要

• 商业应用提速: A generation speed of up to 750 tokens per second drastically reduces response latency, offering immense practical value for highly time-sensitive enterprise applications and business scenarios.
• 跨界算力合作: OpenAI's decision to partner with external hardware provider Cerebras to achieve extreme inference speeds highlights a new trend of deep integration between AI software models and underlying hardware.
