India was a tied #1 at the International Physics Olympiad (IPhO) this year with 5/5 Golds. I analyzed every single medalist upto 2021: 70% of them in the US! Many of these kids will likely go to MIT or IIT and then leave too. The brain drain is very real.






Egocentric human data is abundant, but human motion is not always positive supervision for robot policy due to embodiment gaps. Naive BC co-training can HURT performance ☹️. 🌟Our key finding in **EgoWAM**: the state-prediction branch of a World Action Model effectively bridges this embodiment gap, enabling robot performance to scale with diverse **in-the-wild** human data. 💡The key question then becomes: what world representation transfers best across embodiments? 👇🏻Let’s take a deep dive into it: 🌐 gatech-rl2.github.io/egowam.github.… 🧵[1/]

We're extending access to Claude Fable 5 on all paid plans through July 12.





Why does it work? Our analyses suggest predictive objectives lead to: 💰Richer latent representations 💠Higher effective representation dimensionality 🧠Fewer dormant neurons ⚖️More stable value learning 8/🧵
