X post · Story page
OpenAI is previewing Ultrafast mode: GPT-5.6 Sol at up to 14x its normal speed on Cerebras hardware, up to 750 tokens per second, launching first in the API with select customers.
In plain words
- OpenAI is testing an Ultrafast setting that can run its artificial intelligence system up to 14 times faster than normal.
- Specialized Cerebras computer hardware lets it produce up to 750 tokens, small pieces of text processed by the system, each second.
- A select group of customers will try it first through OpenAI's application programming interface, a way software services exchange requests.
- Faster responses could shorten waiting times for selected customers using the system through their own software.
