Musk Plans xAI Supercomputer, Dubbed ‘Gigafactory of Compute’

Elon Musk has said publicly that his artificial intelligence startup xAI will need a whopping 100,000 specialized semiconductors to train and run the next version of its conversational AI Grok. To make the chatbot smarter, he’s recently told investors xAI plans to string all these chips into a single, massive computer—or what he’s calling a “gigafactory of compute.”

In a May presentation to investors, Musk said he wants to get the supercomputer running by the fall of 2025 and will hold himself personally responsible for delivering it on time. When completed, the connected groups of chips—Nvidia’s flagship H100 graphics processing units—would be at least four times the size of the biggest GPU clusters that exist today, such as those built by Meta Platforms to train its AI models, he told investors.
