Human generated data has fueled incredible AI progress, but what comes next? 📈 On the latest episode of our podcast, Hannah Fry and David Silver, VP of Reinforcement Learning, talk about how we could move from the era of relying on human data to one where AI could learn for

Here is Epoch's second AI+Math Chat, feat. Kevin Buzzard, Yang-Hui He, Alex Kontorovich, and Kristin Lauter! Watch as we discuss the potential and obstructions for AI formalizing mathematics in Lean, and how LLMs learning the rules of arithmetic through pattern-matching might

Better late than never --- Qinghua Liu finally defended his FPO and officially graduated from our group! 🎓 So proud of you, Dr. Liu. You've done so many incredible work on the foundations of reinforcement learning.

Thanks so much, Chi! I’m really grateful to have had you as my advisor. I’ll always miss our time working together at Princeton.

Congrats on the amazing work! Tackling the last 10–20% on miniF2F takes a major leap in capability 🎉. The competition in formal math is getting so intense --- hard to believe Kimina held SOTA for only two weeks before being solidly surpassed by Deepseek.

Writing math proof in Lean is surprisingly addictive. Watching Terence Tao formalize Lean proofs feels like watching a top-tier gamer playing on Twitch. :-) youtube.com/watch?v=c1ixXM…

Tested OpenAI o3 on the final exam from my sophomore-level signal processing/information theory course with ~100 students at Princeton 📊 It scored an impressive 89.5—well above the class average of 72.9, but still short of the top student’s 98+ 💯🎯

Excited to share that the PokeAgent challenge was accepted as a NeurIPS Conference competition! This should serve as an excellent standardized benchmark for competitive games AND ‘speedrunning’ the RPG. I hope to see both the RL and LLM agent communities working together here to eval
