After an unforgettable ride, I’ve decided to move on from @xai and yesterday was my last day. When I first joined, I thought everyone was absolutely nuts for thinking we could deploy 100K GPUs in 4 months, especially without a fully functioning site. Watching us go and double that, and most importantly successfully train Grok 3 made me incredibly proud... and very happy to be wrong. Thank you @elonmusk and everyone at xAI for the rare opportunity to help build something truly foundational with Colossus. It was a privilege to be part of a mission this bold, and to see from the inside what relentless focus and execution really look like. Reporting into Elon and learning directly from him was definitely the best part about working at xAI. Special thanks to everyone on the infrastructure team who met impossible expectations and the entire research team for your partnership throughout. You’re the best! I am sure building Colossus and training Grok 3 are definitely highlights of my career I will remember forever. Jensen Huang was right, Elon and his teams are singular in what they can achieve. Grateful to have played a small part in shaping the future of AI Compute from the inside. Excited for what’s next—more soon. 🚀
