I resigned from xAI today. This company - and the family we became - will stay with me forever. I will deeply miss the people, the warrooms, and all those battles we have fought together. It's time for my next chapter. It is an era with full possibilities: a small team armed

Many people are leaving labs with tons of resources (while legends from pre-AI software are joining the labs). What is most remarkable to me is that the first group seems confident they'll build new companies outside. Anthropic folks are skeptical about that.

Tony Wu is the fourth cofounder to leave xAI in the past year. He led the reasoning org and began reporting to Elon Musk last year. XAI underwent a reorg a few weeks ago and cofounder Guodong Zhang took over some of Wu's responsibilities, insiders said.

Anthropic is still the only AI company that has managed to retain 100% of their cofounders.

Wow. YTW is a xAI co-founder. My guess: team didn't like the X merge first & SpaceX acquisition later.

xAI seems like it's completely cooked. I don't know how you can recover at this point. Grok 4.2 is going to be dead before it arrives. Kinda sad.

xAI co-founder left xAI. I believe this makes it the 4th co-founder to leave. Also Greg Yang is sick. Still wish xAI can build top models.

When leadership goes it usually means the boss isn't happy with their progress. Not good though.
