Simon Willison extracted the transcript of the roadshow video using the MacWhisper transcription tool. In the video, the section on computing mentions that Claude runs on AWS Trainium, Google TPUs, Nvidia GPUs and AMD. The three-day port to AMD would therefore be one illustration of this hardware diversity. These claims come from Anthropic's video and remain statements by the company.
