Elon Musks xAI startet den weltweit ersten Gigawatt-KI-Supercluster, der es mit OpenAI und Anthropic aufnehmen kann

Elon Musk’s xAI launched Colossus 2 on Jan. 17, the world’s first gigawatt-scale AI supercluster, housing roughly 555,000 Nvidia GPUs worth an estimated $18 billion at a Memphis-area facility.

The supercomputer, built in about 18 months using on-site gas turbines and Tesla Megapacks, consumes power equivalent to San Francisco’s peak demand and will be upgraded to 1.5 gigawatts by April, while rivals like OpenAI and Anthropic reportedly won’t match that scale until 2027.

Environmental groups and the EPA have criticized xAI for operating gas turbines without Clean Air Act permits in a Memphis area already suffering from high asthma hospitalization rates.
