Anthropic Gets 220,000 GPUs. Your Claude Code Limits Just Doubled.

This one hit my inbox and I had to read it twice.

Anthropic announced a partnership with SpaceXAI for the entire Colossus 1 data center in Memphis. 220,000 NVIDIA GPUs. 300+ megawatts. That's the largest single compute acquisition by any AI lab. Full stop.

But the part that matters to you right now: Anthropic doubled Claude Code's five-hour window limits for every Pro and Max subscriber, effective immediately. Peak-hours rate reductions are gone. API limits for Opus went up. If you've been hitting rate limits during workday sessions, that wall just moved way back.

I use Claude Code every day in my personal projects, and the rate limits have been the one consistent friction point. Not the model quality, not the context window. The rate limits. Doubling them changes the calculus of how aggressively I can use multi-agent workflows without babysitting token budgets.

Simon Willison flagged three details the main coverage missed. First, Anthropic gets Colossus 1 while xAI keeps the larger Colossus 2 for its own training. Second, Colossus 1 has a rough environmental record, with gas turbines running without Clean Air Act permits by classifying them as "temporary." Third, xAI sent deprecation notices for Grok 4.1 Fast and other models with just two weeks' notice the night before Anthropic's announcement. The timing feels pointed.

Semafor frames this as evidence that compute capacity is replacing traditional capital as the strategic bottleneck. Tokens as currency. It's a big claim, but when a 300MW data center changes hands to power a single model family, the thesis writes itself.

What to do about it: if you're on a Pro or Max plan, go use those limits. Run bigger tasks. Try multi-file refactors you've been splitting into smaller chunks. The constraint that shaped your workflow just changed.
