Tesla Chief Executive Officer Elon Musk signaled a sharper competitive push into artificial intelligence, writing in a series of posts on X that he had “resisted AI for too long” but that "now it is game on." The remarks mark a shift for Musk, who for years warned that the technology could pose an existential threat, even as he backed projects such as OpenAI and later founded his own startup, xAI. Musk said Tesla is "by far the best in the world at real-world AI," asserting the carmaker’s driver-assistance software outperforms rivals, including Alphabet Inc.’s Google and its autonomous-vehicle unit Waymo. He added that Tesla’s approach relies on fewer sensors than Waymo while delivering superior performance, underscoring ambitions to commercialize fully self-driving vehicles. The billionaire pointed to xAI’s recent deployment of 100,000 Nvidia H100 chips in a training cluster nicknamed "Colossus"—one of the fastest such systems—as evidence of accelerating investment. His renewed commitment comes as technology companies race to develop more advanced models capable of approaching artificial general intelligence.
