Llama 3.1 405B now runs at 969 tokens/s on Cerebras Inference

No mention of their direct competitor Groq?

I'm a happily-paying customer of Groq but they aren't competitive against Cerebras in the 405b space (literally at all).

Groq has paying customers below the enterprise-level and actually serves all their models to everyone in a wide berth, unlike Cerebras who is very selective, so they have that going for them. But in terms of sheer speed and in the largest models, Groq doesn't really compare.

Is this because 405b doesn't fit on Groq? If they perform better, I would also have liked to have seen.
