Musk details xAI compute: Colossus 2 to add 660k GB300s across waves by December
CurieuxExplorer · x · 2026-09-25
Elon Musk laid out xAI's supercomputer scale:
- Colossus 1: 150k H100, 50k H200, 30k GB200
- Colossus 2: 110k GB200, 440k GB300
Another 220k GB300s will be fully operational next week, another 220k in November, and possibly 220k more by late December — implying Colossus 2 could exceed 1.1M GB300s by year end.
