Summary
- New Ultrafast mode offers 14x processing speed.
- GPT-5.6 Sol can generate up to 750 tokens per second.
- Partnership with chipmaker Cerebras powers the speed.

OpenAI has launched Ultrafast, a new operational mode designed to significantly accelerate its powerful GPT-5.6 Sol model. This innovative mode reportedly processes information 14 times faster than standard methods, achieving an impressive output of up to 750 tokens per second. Tokens represent distinct text segments generated by AI models.
This breakthrough challenges the previous trade-off between speed and model capability, as stated by OpenAI. Competitors like Anthropic offer faster modes for their models, but OpenAI's Ultrafast appears to set a new benchmark. The accelerated GPT-5.6 Sol is anticipated to enhance various business operations.
Potential applications include incident response, customer service, financial market analysis, and e-commerce. The technology behind Ultrafast is a result of OpenAI's partnership with chip manufacturer Cerebras. This feature is presently in a limited preview phase, with broader access planned as system capacity increases.
