human beings are estimated to use roughly 50 to 100W when idle (up to maybe 1000-2000W when exerting ourselves physically), and I think it's fair to say we're generally intelligent.
Something is fundamentally missing with LLMs w.r.t. intelligence per watt. assuming gpt4 is around human intelligence, that needs 2-4 H100s, so roughly the same and that doesn't include the rest of the computer.
That being said, we're willing to brute force our way to a solution to some extent so maybe it doesn't matter, but I say the fact that we don't use that much energy is proof enough we haven't perfected the architecture yet.
