Reason--Imagine--Act: Closed-Loop LLM Decision Making with World Models for Autonomous Driving

In three linesRIA couples an LLM with an action-conditioned world model for autonomous driving. At each step, the LLM proposes actions, the world model validates via short-horizon rollouts, and a safety scorer selects the safest action. On CARLA (1000 episodes): 80.05% route completion, 51.10% arrival rate, 0.20% collision rate.
