Nvidia's new Groq 3 LPX inference accelerator hit 3,400 tokens per second on Gemma 4 31B, a figure the company says is four times faster than Cerebras. Experts note the benchmark uses at least 64 LPX chips versus Cerebras' one or two accelerators, making the comparison far less clean than it appears.

OpenAI has launched a preview of 'Ultrafast' mode for GPT-5.6 Sol, delivering up to 750 output tokens per second through Cerebras inference hardware. The feature is initially limited to select API customers as part of a tiered speed pricing structure.

OpenAI has introduced 'Ultrafast,' a preview mode that it claims accelerates GPT 5.6 Sol to 14 times standard speed, hitting up to 750 output tokens per second. The feature runs on OpenAI's partnership with chipmaker Cerebras and is currently limited to a small group of customers.

OpenAI is testing an 'Ultrafast' service tier that runs GPT-5.6 Sol up to 14 times faster than standard processing, generating up to 750 output tokens per second using Cerebras infrastructure. Access is currently limited to a waitlist of select customers.
