Kind: research · Impact: medium

## In brief

- Anthropic says its in-house model Mythos ported Claude to AMD GPUs in three days with almost no human intervention.
- Anthropic reportedly runs Claude on four chip families and aims to cut costs and reduce vendor dependence.
- According to the report, AI is reducing the switching cost created by Nvidia's CUDA software ecosystem.

## Why it matters

If AI tools can port AI workloads between GPU vendors quickly, the software lock-in around CUDA may weaken, giving developers more hardware options and bargaining power.
