   Anthropic Says AI Cut Claude’s Switch to AMD GPUs to Three Days

   Anthropic says it used its Mythos model to port Claude to AMD GPUs in three days, with almost no human intervention, compared with six to twelve months using traditional engineering approaches. The figures refer to prompt processing on AMD MI355X GPUs and come from an investor presentation that has not been independently verified. Anthropic says it allocates compute across AWS Trainium, Google TPUs, Nvidia GPUs, and AMD GPUs.
