xAI Colossus
100,000 GPUs in 122 days — the build that reset the industry's clock.
您正在查看一条数据中心记录:一个真实的设施——谁运营它、里面装有什么硬件、电力从何而来。
xAI converted a former Electrolux appliance factory in Memphis into the world's most famous AI supercomputer: roughly 100,000 H100-class GPUs brought online in 122 days in 2024, doubled to ~200,000 within months, running on Spectrum-X Ethernet with Supermicro and Dell systems and Tesla Megapacks buffering power. Dozens of on-site gas turbines bridged the grid gap — and drew air-permit challenges from local groups. Grok 3 and 4 were trained here.
