Personal update: I’ve decided to leave OpenAI. I’m proud to have been part of the custom chip program and grateful to everyone I got to build with and learn from along the way. The density of hardware talent on that team is extraordinary, and I don't think there's a better chip design team anywhere. It's been a wild journey from second hardware hire, 2.4 years ago, to now, and I'm excited to watch these chips become one of the most important engines of AGI. At the same time, I haven’t been able to shake the pull to climb a new mountain from the bottom again! I joined @AnthropicAI this week because I was deeply impressed with the team’s talent, values, and ambition, and I'm already energized by the pace and intensity of the past few days. It’s time to build.
