Is RL + LLMs enough for AGI? — Sholto Douglas & Trenton Bricken

New episode with my good friends Sholto Douglas & Trenton Bricken. Sholto focuses on scaling RL and Trenton researches mechanistic interpretability, both at Anthropic. We talk through what’s changed in the last year of AI research; the new RL regime and how far it can scale; how to trace a model’s thoughts; and how countries, workers, and students should prepare for AGI. See you next year for v3. Enjoy!

EPISODE SUMMARY

In this episode of Dwarkesh Podcast, featuring Dwarkesh Patel and Sholto Douglas, Is RL + LLMs enough for AGI? — Sholto Douglas & Trenton Bricken explores reinforcement learning plus LLMs race toward agentic white‑collar automation Sholto Douglas and Trenton Bricken argue that RL with verifiable rewards on top of large language models has crossed an important threshold: we now have algorithms that can reach expert-human reliability on difficult, well-specified tasks like competitive programming and math.
