Tesla CEO and Twitter/X owner Elon Musk announced Monday that his AI startup, xAI, had officially begun training its Memphis supercomputer, what he describes as “the most powerful AI training cluster in the world.”

Elon Musk’s AI startup xAI has commenced training on its Memphis supercomputer, described as the world’s most powerful AI training cluster. Musk aims to develop the most powerful AI, Grok 3, by December 2024. The supercomputer, housed in a former Electrolux facility in Memphis, uses 100,000 Nvidia H100 GPUs. This marks the largest capital investment by a new company in Memphis’ history, though it will generate only a few hundred local jobs.
