@tiffzhao05 @philhchen @quadrillion_ai lfg tiffany congrats!!

I left Google DeepMind, moved from SF to NYC, all within 2 weeks to join @quadrillion_ai — to build the future of automated research intelligence with the highest slope founder and most talent dense team. I grew up in Silicon Valley — the old Facebook office was my second home. I’d hang out there after school, drawing with my crayons while looking around at the sea of computers with lines of code. Since a young age, I felt empowered to have an array of interests beyond tech: piano, ballet, figure skating, art. The valley embraced diversity of thought, and that’s what inspired me to stay for Stanford and my career thus far. But today, SF is one big hive-mind. So, I moved to NYC, away from family and friends to build a company that doesn’t need to rely on a bubble to survive. I’m meeting customers day after day in all kinds of verticals, connecting with them in different ways and seeing our product bring real value. Here, I’m able to live in diversity of thought. I’m excited to build the future of research in the city of opportunity. Let’s chat if this excites you.

@philhchen @polynoamial @ClemensWinter will miss the shitposting, good luck phil! 👑

Today is my last day at OpenAI. I had the privilege of working with the best researchers in the world across pretraining and RL. I’m most grateful for the mentorship of @polynoamial and @ClemensWinter, who inspired me to pursue ambitious ideas. We’ve trained incredible models over the past few years. In just 4 years, we went from GPT-3 scoring 35% on grade school math to an IMO gold medal result. I’m excited to see how the team will continue to push the frontier beyond my wildest imagination. As for what’s next, I’m excited to share more soon.

Flight just landed and first post I see is grok putting bikinis on all the officials in the china venezuela meeting. very next post is the us striking the hell out of the venezuela capital. what a weird way to start 2026

@BiniIrl TIL shenzhen has been annexed by sf

We need to do something about San Francisco man

@allisontam_ @davidlin210 @christinahkim @max_a_schwarzer prayge brought us through hard times

it was a MASSIVE team effort but special s/o to the early team and believers @gpujihan @davidlin210 @christinahkim @max_a_schwarzer together we learned the more PRAYGE emojis the better the curves

for the first time 5.1 instant uses adaptive reasoning when responding. shipping this led the team down some pretty fun ML rabbit holes! if you’re an RL nerd, please reach out 🙂 I’ll be at neurips looking for folks to join the Science of Posttraining team

1/n I’m really excited to share that our @OpenAI reasoning system got a perfect score of 12/12 during the 2025 ICPC World Finals, the premier collegiate programming competition where top university teams from around the world solve complex algorithmic problems. This would have placed it first among all human participants. 🥇🥇

@chongz @russelljkaplan @alexandr_wang @0xtigs @devindkim @vidhur2k Miss that table :(

We ran weekly poker at Scale for 2 years until we got shut down due to optics. @russelljkaplan mentioned to @alexandr_wang that the game had been shut down, and Alex responded "that's dumb, we should bring it back." We had 4 tables the next week. Alex's been my 🐐 ever since

Yesterday was Devin’s first day at work! Check out how engineering teams are building with Devin so far.

Everyone knows that @NoamShazeer is a genius, but one thing that most people don't know is how kind and honest he is. His treatment of *all* employees in the events today was exceptionally fair and generous. 10/10 would work for him again.
