SAN FRANCISCO—At its Code with Claude developer conference on Wednesday, Anthropic announced a deal with SpaceX to utilize the entire compute capacity of the latter’s data center in Memphis, Tennessee.
On stage at the conference, CEO Dario Amodei said the deal was intended to increase usage limits for Anthropic’s Pro and Max plan subscribers.
The announcement was accompanied by an immediate increase in those usage limits; Anthropic doubled Claude Code’s five-hour window limits for Pro and Max subscribers, removed the peak-hours limit reduction on Claude Code for those same accounts, and raised API limits for its Opus model. The table below outlining the Opus changes was shared in the company’s blog post on the topic.
Anthropic claims the deal gives the company access to more than 300 megawatts of new compute capacity. For its part, SpaceX focused its announcement on the capability of the Colossus 1 supercomputer that’s at the center of the deal. “Colossus 1 features over 220,000 NVIDIA GPUs, including dense deployments of H100, H200, and next-generation GB200 accelerators,” SpaceX wrote.
Additionally, Anthropic “expressed interest” in working with SpaceX to build up “multiple gigawatts” of orbital compute capacity, tying into a recent (but unproven) focus on exploring orbital data centers as an answer to the problem that “compute required to train and operate the next generation of these systems is outpacing what terrestrial power, land, and cooling can deliver on the timelines that matter.”
The deal might be surprising to those who have followed Musk’s recent public comments—he was, until now, critical of Anthropic. For example, in February, he declared on X that “Anthropic hates Western Civilization,” while sharing a false tweet from Trump administration official Emil Michael about Anthropic’s practices with its constitution for Claude.
