Output from Cerebras with GPT model is 750 tokens per second.

Don’t blink.

Answering 2,500 independent questions is an embarrassingly parallel workload, all it needs is scale out. It would be more meaningful to know how much time was required for a single complete answer to a difficult HLE question.

>Answering 2,500 independent questions is an embarrassingly parallel workload

So is calculating the total time required to answer all of the questions.

Amadahl’s law dictates it’s approximately always better (as in, more efficient computationally) to have one super fast thing than many slower things doing the same job in parallel.

Such a deep and smart insight.

But why is that important if they're measuring time?

ChatJimmy is a much smaller model and, AFAIK, has no reasoning capability. Absolutely insane raw speed, like a supercar, while Sol is more like a freight truck.

Yes. but for embarrassingly parallel tasks it barely matters.

The corresponding OpenAI post https://openai.com/index/previewing-ultrafast/ There is no pricing info, which could mean it's "if you have to ask..." territory or they are simply gauging interest before deciding

They're nearly certainly going to use it internally to speed up research that is serially bottlenecked. I would bet this is why they're interested in the Cerebras partnership more than everything else

Obviously this is a much smaller model, but I really can't wait for ASICs to take over the LLM space.

Imagine running a model like Sol/Fable (even half the size with 60-70% of it's intelligence) on your own ASIC hardware.
