SpaceX rented Colossus 1 to Anthropic because it couldn't make the data centre work for Grok
SpaceX rented Colossus 1 to Anthropic after hitting latency and chip mismatch issues trying to use it for Grok. The newer facilities use uniform Blackwell chips.
TL;DR
- SpaceX rented its Colossus 1 data center to Anthropic due to internal AI model utilization issues.
- Latency problems and aging network infrastructure prevented SpaceX from connecting Colossus 1 effectively with other data centers for AI training.
- A hardware mismatch, with a mix of Nvidia chip generations in Colossus 1, created bottlenecks for distributed training.
- Anthropic pays $1.25 billion monthly for Colossus 1, contributing to SpaceX's substantial compute revenue.
- The underperformance of Grok models reduces the urgency for SpaceX to reclaim the data center capacity.
