## Summary

Anthropic says its Mythos model got Claude running on AMD GPUs in three days with basically no human intervention. The quoted Anthropic road show video says Claude ported or wrote almost 100% of the kernels. The attached chart compares the three-day timeline with an estimated six to twelve months under a traditional approach, which the company says took dozens of engineers months of work.

## Post

From the Anthropic Road Show video:
'This has also made us really good at bringing up new chips. As an example, this year, we started working with AMD GPUs for the first time. In the past, bringing on a new chip platform took dozens of engineers months of work. This time we had Mythos try it out. It got Claude running on AMD in just 3 days with basically no human intervention. Claude ported or wrote almost 100% of the kernels.'
