Sergey Levine Proposes Applying RL to Language Instructions for VLAs
svlevine · x · 2026-07-04
UC Berkeley researcher Sergey Levine proposes a new approach: instead of applying reinforcement learning directly to robot actions, apply RL to the "language instructions" sent to the Vision-Language-Action (VLA) model. Because strong Vision-Language Models have excellent priors for sensible semantic instructions, the RL search space is drastically reduced, making training significantly easier.
