SpaceX develops custom 'Kessel' AI system with 72 Nvidia Rubin GPUs

By PulseAugur Editorial · [1 sources] ·

SpaceX is reportedly developing a custom rack-scale AI system called 'Kessel' for its data centers, including those in space. This system utilizes 72 Nvidia Rubin GPUs and replaces traditional NVLink cable assemblies with a large, 84-layer printed circuit board for interconnectivity. By sourcing components directly and managing its own supply chain, SpaceX aims for greater control and optimization, particularly for orbital deployments. AI

IMPACT This custom hardware development by SpaceX could accelerate the deployment of advanced AI capabilities in specialized environments like space, potentially influencing future data center designs.
