NVIDIA CEO Jensen Huang called Elon Musk a superhero. Before making those remarks, xAI set an impressive record with its "Colossus" supercomputer used to train Grok. In just 19 days, xAI installed 100,000 NVIDIA H100 chips to support Grok. Huang described the installation speed as "incredible," as this process typically takes years. Additionally, Musk plans to add 50,000 H200 chips. (Motley Fool)
