xAI's Colossus 2 supercomputing infrastructure has officially come online, marking a major milestone in large-scale GPU deployment. The facility currently operates at 1GW capacity, with plans to expand to 1.5GW by April—bringing total GPU allocation beyond 900,000 units. This aggressive buildout reflects intensifying competition in high-performance computing infrastructure, as AI development demands push the boundaries of what's technically feasible. The scale of this deployment underscores how computing power has become a critical bottleneck in the AI arms race, with implications extending across crypto infrastructure, on-chain AI applications, and decentralized compute networks.
