Anthropic Says Its AI Model Cut AMD Chip Switch to Three Days. Why it Could be a Challenge to Nvidia

Anthropic claims its AI model, Mythos, enabled Claude to run on AMD chips in three days, reducing a previously months-long process. The company, preparing for an IPO, says this flexibility could help customers choose chips based on availability, performance, and cost. Anthropic uses a multi-chip architecture, including Nvidia and AMD GPUs, to optimize computing resources. AMD has committed to a $5 billion investment and GPU deployments with Anthropic.
