Musk: SpaceX and xAI to exclusively use Nvidia GPUs, plans to launch Vera Rubin NVL72 into orbit next year

Elon Musk announced that SpaceX and xAI will exclusively use Nvidia GPUs, citing the Vera Rubin NVL72 rack-scale system as the best AI compute architecture available. During SpaceX's earnings call, Musk praised the cable-less design of the NVL72 VR200 computer for its serviceability and reliability. He also revealed plans to deploy an optimized version of the Vera Rubin NVL72 in space via the Starmind AI satellite, with launches expected to begin next year. This marks a significant endorsement for Nvidia over competitors like AMD, as xAI has historically used only Nvidia hardware for training its Grok models. The space deployment would be far more ambitious than Nvidia's own Space-1 Vera Rubin Module, raising questions about cooling and reliability in orbit.
