xAI just announced a massive $20B+ infrastructure expansion in Southaven, Mississippi. The project centers on building a colossal ~800,000 square foot facility—dubbed MACROHARDRR—that'll dramatically boost the Colossus supercomputing cluster to nearly 2 gigawatts of processing power. Once operational, this becomes the most powerful compute infrastructure on the planet. The scale here is staggering: we're talking about reshaping what's possible for AI model training and deployment at an unprecedented level.
