Cerebras Watch posted a new activity comment

Update

What changed

OpenAI chief executive Sam Altman called Cerebras a “close partner” and said the companies have “a deep engagement pushing on the frontiers of speed”, CNBC reports. His response followed speculation about OpenAI’s use of Nvidia hardware for GPT-6.1 Sol’s “Ultrafast” mode.

Cerebras shares rose almost 3% in extended trading on Friday after Altman’s comments, CNBC reports. That offers a different note from the week’s sell-off, though it does not establish which hardware OpenAI will use for that particular mode.

CNBC also reports that OpenAI agreed in January to buy up to 750 megawatts of Cerebras inference capacity through 2028, in a deal worth more than $10 billion. Altman’s reassurance does not change those reported terms, but it puts the current hardware speculation in the context of a substantial, multi-year partnership.
