SAN FRANCISCO – Wednesday at Anthropic’s Code developer conference with Claude announced An agreement with SpaceX to use all the computing capacity of its data center in Memphis, Tennessee.
At the conference, CEO Dario Amodei said the deal aims to increase usage limits for Anthropic’s Pro and Max plan subscribers.
The announcement was accompanied by an increase in those usage limits; Anthropic doubled the five-hour window limits for Claude Code’s Pro and Max subscribers, removed the peak hour limit reduction in Claude Code for the same accounts, and increased API limits for the Opus model. The following chart outlining the Opus changes was shared in the company’s blog post on the topic.
The Opus usage limit changes on May 6, 2026.
Anthropic claims the deal gives the company access to more than 300 megawatts of new computing capacity. For its part, SpaceX focused its announcement on the capabilities of the Colossus 1 supercomputer at the heart of the deal. “Colossus 1 has more than 220,000 NVIDIA GPUs, including a dense array of H100, H200 and next-generation GB200 accelerators,” SpaceX he wrote.
In addition, Anthropic has “expressed interest” in working with SpaceX to add “many gigawatts” of orbital computing capacity. unproven) focus on exploring orbital data centers as a response to the challenge that “the computation required to develop and operate the next generation of these systems exceeds what terrestrial power, land, and cooling can deliver on critical timescales.”
The deal may come as a surprise to those who have followed Musk’s recent public comments — he has been critical of Anthropic until now. For example, in February he announced “Anthropic Hates Western Civilization” on X, when Trump administration official Emil Michael shared a false tweet about Anthropic’s applications to Claude’s constitution.
