The video’s “Approach to compute” section, featuring co-founder Tom Brown, reportedly says Anthropic trains and serves Claude across AWS Trainium, Google TPUs, NVIDIA GPUs and AMD GPUs. It describes the company’s multi-chip strategy as requiring tailored software and inference stacks for each platform, according to Willison’s account of the video.
The video also reportedly says Anthropic began working with AMD GPUs for the first time in 2026. It claims that Mythos got Claude running on AMD in three days with essentially no human intervention, and that Claude ported or wrote almost all of the kernels for the deployment. Those operational claims were not independently verified in the supplied material.
Willison wrote that he was unsure why no official video transcript was available and said he extracted the quoted material using MacWhisper. The supplied account therefore presents the infrastructure and deployment details as claims from the roadshow video rather than independently confirmed results.
