Elon Musk says he is spending four days a week "night and day" at his facility in Memphis to get SpaceX's supercompute cluster online.

He expects to be able to bring 13 gigawatts of computing capacity online by the end of next year. As of Sept. 30, SpaceX said it had nameplate compute at 1.7 gigawatts, up from 0.6 GW a year earlier.

Musk has already built a massive data center, called "Colossus," that houses over 200,000 Nvidia chips. SpaceX is close to finishing the second facility, which will be even bigger. He calls it Colossus 2.
