Overview
- Anthropic and SpaceX said Wednesday that Anthropic will use the full Colossus 1 data center in Memphis, gaining more than 300 megawatts of capacity and access to roughly 220,000 Nvidia GPUs within a month.
- Anthropic made immediate changes for paying users by doubling Claude Code’s five‑hour limit, removing peak‑hour caps for Pro and Max plans, and raising API limits for its Claude Opus models.
- Elon Musk reversed his earlier criticism after meeting Anthropic leaders, praised their safety work, and said xAI now operates as SpaceXAI with AI training shifted to a larger Colossus 2 system.
- Anthropic also expressed interest in partnering with SpaceX on multi‑gigawatt orbital data centers, a long‑term plan SpaceX promotes as a way to tap abundant power as it prepares for an IPO.
- The deal extends Anthropic’s multi‑vendor compute buildup with Amazon, Google, Microsoft and others, and it lands as Pentagon‑related lawsuits continue and Memphis residents protest Colossus’s gas‑turbine pollution.
