Elon Musk has unveiled a major breakthrough in artificial intelligence infrastructure. The Colossus 2 supercomputer has officially gone live, marking the world's first gigawatt-scale AI training cluster to reach operational status. This represents a significant milestone in large-scale computing, providing unprecedented processing power for deep learning models. The Colossus system currently operates at 1 gigawatt capacity, establishing it as the most powerful single training facility of its kind. Building on this momentum, an expanded upgrade pushing the Colossus cluster to 1.5 gigawatts is scheduled for April, which will further cement its position as the industry's leading AI infrastructure backbone. The deployment of such advanced Colossus technology underscores the rapid acceleration of computational demands in modern AI development.
