The report said a section featuring Anthropic co-founder Tom Brown described the company’s approach to training and serving Claude across four chip families: AWS Trainium, Google TPUs, NVIDIA GPUs and AMD GPUs. The explanation presented that model as a multi-chip strategy and linked it to the development of compute multipliers, described as improvements that increase total effective compute.
Simon Willison’s Weblog also reported that the video said Anthropic had started working with AMD GPUs for the first time that year. In the account attributed to the roadshow video, Mythos got Claude running on AMD in three days with almost no human intervention, while Claude ported or wrote nearly all of the kernels. Those claims were presented through the extracted transcript and were not independently verified in the supplied evidence.
Willison said he extracted the transcript with MacWhisper because no official video transcript was available to him, according to the same report. The supplied material therefore does not establish the transcript as an official record or independently confirm the claims from the roadshow video.
