I will continue to proudly say I never use LLMs. Not for writing, not for coding, and certainly not for "art". Just haven't felt the need at all.

thrilled that we'll be presenting this paper as a spotlight at #ICML2025 . come by our poster in vancouver to chat with us about the use of LLMs for advancing neuroscience! here's the camera-ready version: openreview.net/forum?id=dhRXG…

really excited about this new work we just put out, led by my students Roger Creus Castanyer & Johan S. Obando 👍🏽 , where we examine the challenges of gradient propagation when scaling deep RL networks. roger & johan put in a lot of work and care in this work, check out more details in 🧵👇🏾 !

🚨 Excite to share "Stable Gradients for Stable Learning at Scale in Deep Reinforcement Learning" work. 🥳 We tackle gradient instability in large deep RL networks, enabling stable and scalable learning with strong performance across the board. 📄 Paper: arxiv.org/abs/2506.15544

B/f joining Brain in 2017 I interviewed with a startup doing smthg similar (w/ lots more manual effort). In intrvw I noticed a sleep pod & said "we have nap pods at Google also". They said "yeah, we regularly spend the full night at office"... I got the offer, but said no 😊
