You cannot infer this because they only show the tokens per second per user. One way to get a higher number is to have fewer users per chip.

I'm pretty sure Cerebras has a confidentiality agreement with OpenAI, and this press release was carefully constructed to avoid leaking details about the model weights. For example, the graph of tokens per second vs. tokens per second per user doesn't have any numbers that would allow you to translate between the two. (And in any case the relationship depends on the model.)

Didn't they say that they can support bigger models now?

(Where did you see that?)

This was also interesting: "CS-4 delivers more than 1,000 tokens per second on models exceeding 10 trillion parameters." Was it known that there were 10 trillion parameter models in use?

I think the frontier providers keep the size of their models carefully hidden.
