Anthropic to use SpaceX’s Colossus 1 supercomputer for inference
Anthropic just secured access to Colossus 1—the supercomputer originally built for xAI. Here's what that means for Claude's inference costs and speed.
Why it matters
Anthropic is outsourcing inference to SpaceX's cutting-edge supercomputer infrastructure, a strategic move to reduce capex while scaling Claude deployment. This signals a shift in how frontier labs are leveraging third-party compute capacity rather than building entirely in-house.
