This is nonsense what do you mean? Mistral uses Cerebras for their LLMs as well. [0]

It's certainly not "untested".

Tested at Mistral’s scale is a very different thing to tested at OpenAI’s scale.

The scale of being "tested" clearly convinced Meta (beyond OpenAI's scale) [0] HuggingFace [1], Perplexity [2] and unsuprisingly many others in the AI industry [3] that require more compute than GPUs can deliver.

So labelling it "untested" even at Meta's scale as a customer (which exceeds OpenAI's scale) is quiet nonsensical and frankly an uninformed take.

Meta didn't offer it. They offered the free llama version on their cloud. Maybe now Zuck will be conincrto buy their chips though
