Anthropic Leases Full Capacity of SpaceX Colossus 1 Supercluster for Claude AI Training

Which houses more than 220,000 Nvidia processors. The agreement will deliver 300 megawatts of new capacity within a month, easing constraints that followed surging demand for its Claude Code AI coding tool. The announcement came during Anthropic's developer day held in San Francisco on Wednesday.

At the event the company unveiled a new Claude feature called "dreaming" that is available immediately as a research preview with its software for managing agents. The dreaming capability is designed to let AI systems review their work between sessions, identify patterns and update files that store user preferences and other context.

Boris Cherny, Anthropic's head of Claude Code, told the audience that the default workflow has shifted.

'" Cherny closed the keynote by stating, "The capability is already here. " Buoyed by the new capacity and other recent agreements, Anthropic is doubling Claude Code's rate limits for paid plans, removing peak-hour usage caps for Pro and Max accounts, and sharply increasing the volume of requests developers can make to its Claude Opus models.

Elon Musk stated on X that he decided to lease the computing power after spending time with Anthropic leaders last week.

SpaceX has already moved its own AI training efforts to Colossus 2. Musk said he would provide computing capacity to other AI companies that make similar efforts to favour humanity. " Anthropic said it is interested in working with SpaceX to develop multiple gigawatts of space-based orbital data centres, one of Musk's stated long-term goals.

The partnership supplies SpaceX with a prominent AI customer as the company prepares for an initial public offering. It also intensifies competition in the enterprise AI coding market, where Claude Code has seen rapid adoption.
