OpenAI has launched a new 'Ultrafast' mode for its GPT-5.6 Sol model, enabling it to process information up to 14 times faster than standard speeds. This acceleration, achieved through a partnership with chipmaker Cerebras, allows the model to generate up to 750 tokens per second. The Ultrafast mode is currently in a preview phase for select customers and is intended for applications like customer service, financial analysis, and incident response. Notably, OpenAI had previously acquired a 4.2% stake in Cerebras, underscoring the strategic importance of this collaboration. AI
