## Summary

Anthropic says its Claude model was running on AMD GPUs three days after work began, with almost no human intervention. The company says Mythos wrote or ported nearly 100 percent of the kernels, compared with six to twelve months for traditional engineering. The figures come from an investor presentation and have not been independently verified.

## Why it matters

The article links Anthropic's porting claims to Nvidia's CUDA lead and to the financial ties between Anthropic and both chipmakers, which shows the business stakes behind the technical claim.
