Co-founder Tom Brown says Claude now runs across AWS Trainium, Google TPUs, NVIDIA GPUs, and AMD GPUs.
Anthropic opened its IPO roadshow with a video that details how the company trains and serves Claude. Co-founder Tom Brown describes a multi-chip strategy spanning AWS Trainium, Google TPUs, NVIDIA GPUs, and AMD GPUs. Brown says Anthropic placed an unconventional bet early on running AI models across different silicon.
Each chip family requires its own tailored software and inference stack, which Brown calls expensive and difficult to build. Anthropic has worked on this problem for years, and the company last September described bugs that hit only its TPU deployments. Simon Willison extracted a transcript of the video himself and published it alongside highlights.
Anthropic says a tool called Mythos brought Claude to AMD GPUs in three days this year with almost no human intervention. Past platform additions took dozens of engineers months of work. Claude wrote or ported nearly all the kernels. Builders weighing vendor lock-in can study how tailored per-chip stacks lower the cost of adding hardware.
Anthropic calls compute multipliers its second driver of advantage. Brown describes a 4x multiplier as an example where 25 units of physical compute train a model that would need 100. Each multiplier stacks on the ones before it, and Brown expects Claude to find them unaided as recursive self-improvement approaches. Watch whether Anthropic publishes measured multiplier figures after the roadshow.
What matters
- Anthropic released roadshow video describing how it trains and serves Claude across four chip families.
- Builders should note a multi-chip stack lets Anthropic pick capacity without locking into one vendor.
- Watch next for details on how much of that tooling Anthropic exposes to enterprise customers.
