SAN FRANCISCO—At its Code with Cloud developer conference on Wednesday, Anthropic announced an agreement with SpaceX to use the entire compute capacity of SpaceX’s data center in Memphis, Tennessee.
On stage at the conference, CEO Dario Amodei said the deal is aimed at increasing usage limits for Anthropic’s Pro and Max plan customers.
The announcement was accompanied by an increase in those usage limits; Anthropic doubled the five-hour window limit on cloud code for Pro and Max customers, removed the peak-hours limit reduction on cloud code for the same accounts, and increased the API limit 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 MW of new computing capacity. For its part, SpaceX focused its announcement on the capability of the Colossus 1 supercomputer that is at the heart of the deal. “Colossus 1 has more than 220,000 NVIDIA GPUs, including a dense deployment of H100, H200, and next-generation GB200 accelerators,” SpaceX wrote.
Additionally, Anthropic “expressed interest” in working with SpaceX to build out “multiple gigawatts” of orbital compute capacity, noting a recent (but unproven) focus on exploring orbital data centers as an answer to the problem that “the compute terrestrial power, land, and cooling required to train and operate the next generation of these systems is exceeding the time frame that matters.”
The deal may be surprising to those who have followed Musk’s recent public comments – he has been critical of Anthropic until now. For example, in February, he declared on Twitter that “Anthropic hates Western civilization,” while Trump administration official Emile Michel shared a false tweet about Anthropic’s practices with Claude’s Constitution.
