must be doing something good

@textangel @elonmusk It was a great pleasure working with you, Andrew! It was an absolute great run, and I’m grateful for your hard work and all the wonderful moments we shared. Wishing you all the best!

I’ve also left XAI this week. I worked on several improvements to our favorite app and recommendation model, including the X video feed, search bar, user modeling, starter-packs and the home feed model. I wholeheartedly want to thank @elonmusk for creating this org that the world needs. Incredibly grateful for the stellar no pun intended team with @nikitabier @TheGregYang @VastoLorde95, @skhare95, @haitong_yu, and so many others. So much love and gratitude to this intensely driven group of people. I’ve known some of this team from the old Twitter days, and it is 1000% the insanely best it’s even been, with full sincerity they are killing it, and it’s because they are good and they care. XAI has a wartime mentality, and it is the only way we put compute on the moon and beyond. Life is meant to be lived with a sense of mission and with intensity and people will see one day, that the vision, dreams, and ambitious scope at this company will outstrip all others. This is a wonderful thing that one does not understand unless they do it. I hope the team maintains that sense of drive and purpose, it is humans not ideas that change the world, and xAI is one of the few and rare places where that understanding becomes reality. I’m excited about the future- not sure what I’ll be doing yet (my DMs are open), but there is a world to be changed and no time to waste. Go team, stay focused, be energized, I can’t wait to see you all on the moon and beyond, believe me when I say there is no one that I trust more on the entire planet to get there, there is a world to win.

@jimmybajimmyba @elonmusk Thanks for your leadership and inspiration, Jimmy! Best wishes for your next chapter!

Last day at xAI. xAI's mission is push humanity up the Kardashev tech tree. Grateful to have helped cofound at the start. And enormous thanks to @elonmusk for bringing us together on this incredible journey. So proud of what the xAI team has done and will continue to stay close as a friend of the team. Thank you all for the grind together. The people and camaraderie are the real treasures at this place. We are heading to an age of 100x productivity with the right tools. Recursive self improvement loops likely go live in the next 12mo. It’s time to recalibrate my gradient on the big picture. 2026 is gonna be insane and likely the busiest (and most consequential) year for the future of our species.

@SeanXC2030 Thank you 🙏🏻

@shayan_ Congrats, Shayan. Looking forward to more amazing work

Career update: I left xAI to start something new, closing my 7+ year chapter working at Twitter, X, and xAI with so much gratitude. xAI is truly an extraordinary place. The team is incredibly hardcore and talented, shipping at a pace that shouldn’t be possible. From the Home Timeline at X to Grok 2, 3, and 4 at xAI, I worked across product infra and model behavior post-training, from memory to coding infra, agents, and more. Pure startup mode, every day. Working closely with Elon across X and xAI, I saw what happens when you refuse to accept impossible as an answer. I learned to embody obsessive attention to detail, maniacal urgency, and to think from first principles. I’m deeply grateful to @elonmusk for the experience, to @wanghaofei for the trust and support throughout Twitter/X, and to @TheGregYang and @ibab for believing in me. And to the many incredible people I had the privilege to work with along the way, thank you! Now, I’m excited to take the leap and build something new, focused on accelerating science. More soon.

@PeilinYang Thanks Peilin! 🙏🏻🙏🏻

@shayan_ Congrats on the great run Shayan! Looking forward to whatever you will be doing next!

@Yuhu_ai_ Wish you the best Tony! Thanks for your leadership!

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 with AIs can move mountains and redefine what's possible. Thank you to the entire xAI family. Onward. 🚀 And to Elon @elonmusk - thank you for believing in the mission and for the ride of a lifetime.

@Najeebkhuram Thank you so much 🙏🏻🙏🏻
