## Colossus 2: Power Estimates Despite Elon Musk's claims that xAI's Colossus 2 has already reached a 1 GW scale, satellite analysis by Epoch AI indicates the supercomputer is still far below that level. The main reason would be a limited cooling capacity. ## Limited Cooling Capacity Satellite imagery suggests the site has a cooling capacity of approximately 350 megawatts, a considerably lower value than the declared gigawatt. This data casts doubt on the actual computing power currently available for the xAI project. ## The Context of Supercomputers Supercomputers are high-performance computing systems used to solve complex problems in various fields, from scientific research to artificial intelligence. Their efficiency depends not only on the computing power of the processors, but also on the ability to dissipate the heat generated during operation.
