Models aren’t everything. You need physical infrastructure at scale for inference, which is where the economic power comes from. Chinese hardware makes double the heat and needs at least double the energy input.
even if true, luckily for them, double the heat and double the energy input aren't an issue, and they have more physical infrastructure at scale too
And 3 years ago they were producing no heat and required no energy because they did not exist. Clearly they are catching up
