Two Models, One Gradient: Making World-Model RL Work for Contact-Rich Robots

Embodied AI 101 · Sep 5, 2026 · 33m · transcript

Breaks intractable full world-model RL into a heavy global trajectory model combined with a lightweight latent local dynamics approximator, enabling scalable RL for contact-rich humanoid skills without backpropagating through the full model. In this episode of Embodied AI 101, we explore "Two Models, One Gradient: Making World-Model RL Work for Contact-Rich Robots". We break down the research, methodology, and real-world implications for robotics, AI, and physical intelligence. Embodied AI 101 covers the latest research at the intersection of AI and physical intelligence — robotics…
