Anthropic IPO roadshow video details multi-chip Claude training and serving strategy

Anthropic kicked off its IPO roadshow yesterday, and its roadshow video disclosed previously unreleased details about how the business works, including a section on compute strategy with co-founder Tom Brown. Brown said Anthropic trains and serves Claude across AWS Trainium, Google TPUs, NVIDIA GPUs and AMD GPUs, and that when the company began working with AMD GPUs this year, a system called Mythos got Claude running on AMD in three days with basically no human intervention, porting or writing almost 100% of the kernels. He also described compute multipliers as a second driver of compute advantage, saying each multiplier stacks on the ones before it and that Claude may eventually discover them entirely by itself.
