Source: xAI: New compute partnership with Anthropic

SpaceXSI, the former xAI, signed an agreement to give Anthropic access to Colossus 1, which it said has more than 220,000 NVIDIA GPUs including H100, H200 and GB200 accelerators. Anthropic plans to use the compute to raise capacity for Claude Pro and Claude Max subscribers.

Why it matters

A rival lab’s supercomputer now serves Claude users, a sign of how short frontier compute supply is.
