Anthropic has incorporated SpaceX's computing resources and increased the rate limits for the Opus API.

      Claude Code's five-hour rate limits will be increased to double for Pro, Max, Team, and seat-based Enterprise plans starting Tuesday, with the removal of peak-hour throttling for Pro and Max accounts. This enhancement is made possible through a new agreement with Anthropic to utilize all computing capacity at SpaceX's Colossus 1 data center.

      On Tuesday, Anthropic announced significant increases in the rate limits for Claude Code and the Claude Opus API, with three immediate changes. The new updates state that Claude Code's five-hour rate limits will double for Pro, Max, Team, and enterprise plans; peak-hour limit reductions have been eliminated for Pro and Max accounts; and there are substantial increases in API rate limits for Claude Opus models, with the updated limits released.

      The capacity for these changes is sourced from a new compute deal with SpaceX, where Anthropic will utilize the entire compute capacity of SpaceX's Colossus 1 data center, which offers over 300 megawatts of capacity and more than 220,000 Nvidia GPUs within a month. Anthropic indicated that this additional capacity will enhance service for Claude Pro and Claude Max users.

      In the announcement, Anthropic also expressed its intention to collaborate with SpaceX to develop several gigawatts of orbital AI compute capacity, although no formal agreement has been made yet.

      This SpaceX partnership adds to a series of other recent computing commitments. Anthropic has a potential 5-gigawatt agreement with Amazon that is set to bring nearly 1 GW of new capacity online by the end of 2026; a 5 GW deal with Google and Broadcom, which is expected to start coming online in 2027; a strategic partnership with Microsoft and Nvidia that involves $30 billion of Azure capacity; and a $50 billion investment in American AI infrastructure through Fluidstack.

      Anthropic utilizes a combination of hardware for training and serving Claude, including AWS Trainium, Google TPUs, and Nvidia GPUs. The company is also actively searching for opportunities to increase capacity.

      Upcoming expansions will also be international. The recent collaboration with Amazon will enhance inference capacity in Asia and Europe, catering to enterprise customers in regulated sectors that require regional infrastructure for compliance and data residency. Anthropic emphasizes a careful approach to adding capacity, partnering only with what it considers democratic nations with legal and regulatory frameworks that can support substantial investments.

      Additionally, the company reaffirmed its earlier commitment to cover any increases in consumer electricity prices resulting from its US data centers and is considering extending this commitment to new locations as it continues international expansion.

      The primary change for users is as follows: Pro and Max subscribers will see the doubling of Claude Code’s five-hour usage windows and the lifting of peak-hour throttling, effective Tuesday. The Opus API rate-limit increases will also take effect on the same date.
