Latest update (11-11 10:11): Anthropic's IPO roadshow video details its multi-chip compute strategy

Overview: Anthropic says its Mythos model got Claude running on AMD GPUs three days after work began, with almost no human intervention. The company says Mythos wrote or ported nearly 100 percent of the kernels, compared with an estimated six to twelve months and dozens of engineers under a traditional approach. The figures appear in Anthropic's IPO roadshow video, which began November 10, 2026, and no independent verification has been reported.

The roadshow video also says Anthropic trains and serves Claude across AWS Trainium, Google TPUs, NVIDIA GPUs and AMD GPUs, according to co-founder Tom Brown as reported by Simon Willison. The video says Anthropic tracks compute multipliers as a source of advantage.
