Why does it matter?
A 9 GW training site would make power availability one of the hardest constraints on frontier AI.
Direct quote
However, 9 GW of power is equivalent to 9 nuclear reactors, a scale beyond any existing industrial facility. To overcome power constraints, companies may increasingly use decentralized training approaches, which would allow them to distribute a training run across AI supercomputers in several locations.
