impulser_ | on: SpaceX S-1
Well Colossus 1 has 230k GPUs, including 30k GB200s and Colossus 2 has 550k GB200s & GB300s.

So my guess on costs would be like ~$10B for Colossus 1, and Colossus 2 would be like ~20b.

a GB300 rack is like 5-6 million so seems a bit low.

Yeah, maybe these aren't good guesses. I was basing it off CapEx and Elon's tweet about them. Maybe C2 isn't completely filled yet.
