This week, Anthropic announced that it signed an agreement with SpaceX for all of the Colossus 1 data center compute capacity. While this is a big deal in the industry. It is also one that hits close to home at STH.
Anthropic Signs SpaceX Colossus 1 Data Center to Boost Capacity
If you have been using Claude Opus over the past few weeks, you have likely noticed errors, rate limits, and many have suggested lower quality outputs. Make no mistake, I think Claude Opus 4.7 is awesome. You may have seen we used it to help with things like setting up the BIG AI Cluster Little Power the 8x NVIDIA GB10 Cluster. Ultimately, the service issues meant that our current GB10 cluster dashboard is now maintained by Codex, as we kept getting service errors while Anthropic struggled with capacity. That Codex swap has had its own challenges. Still, it shows that as the model got better, usage went up, and up by a lot, which is one of the reasons Anthropic found itself urgently needing more compute. It contacted SpaceX, and SpaceX signed an agreement to lease the Colossus 1 data center’s compute capacity. That led Anthropic to provide updated API rate limits.
Of course, to me and to STH, the Colossus 1 data center is one that hits home a bit more.
We were able to show you inside part of the Colossus 1 data center after it went online with 100,000 GPUs.
Anthropic’s announcement, as well as several other posts, noted that since we toured Colossus 1, it has more than doubled in size to 220,000 NVIDIA GPUs.
Final Words
It is neat when something we have toured makes the news again, many quarters later. What is perhaps even more exciting is when that data center has an impact, turning around a service we have been using to provide more capacity. From an industry standpoint, Colossus 1 was in the H100 generation, which shows that even previous-generation NVIDIA GPUs can be useful for frontier labs.
