elonmusk · x · 2026-09-25
Elon Musk laid out xAI's compute footprint on X: Colossus 1 runs 150k H100s, 50k H200s and 30k GB200s, while Colossus 2 currently holds 110k GB200s and 440k GB300s. Another 220k GB300s go fully operational next week, another 220k in November, and possibly a further 220k by late December — pushing Colossus 2 toward roughly 1M GB300s within months.
