If you’ve ever found yourself wishing that ChatGPT was a little bit quicker on the uptake, OpenAI seems to be answering your prayers.
The AI lab has rolled out a new mode called Ultrafast, which it says is designed to seriously accelerate the pace at which its latest and most powerful model, GPT-5.6 Sol, accomplishes its work.
The company says that Ultrafast can work at 14x the speed of standard processing, delivering up to 750 output tokens — such tokens represent the distinct pieces of text generated by an LLM when it interacts with a human — per second.
“Until now, getting real-time speed typically meant choosing a smaller or more specialized model,” the company said in the blog post on Thursday. “Ultrafast points to progress in a new direction: more useful work per second.”
