Distributed training: how one model gets split across thousands of chips Lesson

No single chip can hold a frontier model, so training is split across thousands of them in four distinct ways -- by data, by layer, by tensor, and by expert -- and choosing the right mix is what separates a cluster running at a third of its potential from one running at a tenth.
