Additional Information

At Colossus 2, the first batch of 550k GB200s & GB300s, also for training, start going online in a few weeks.

550k GB200/GB300 planned. Unclear what the proportion of GB200 vs GB300 will be. The first 110k will be GB200s. I will naively assume that the remaining will be split 50/50 GB200/GB300, so 330k GB200s 220k GB300s - Elon has claimed that this will be complete in 6-9 months, so presumably early-mid 2026
