A Future‑Predicting Critic Propels VLA Reinforcement Learning

The World Critic Model (WCM) augments the critic in vision‑language‑action reinforcement learning with future state prediction, enabling robots to evaluate not only the current value but also anticipate upcoming dynamics, which dramatically improves both in‑distribution and out‑of‑distribution performance across multiple benchmarks.
