CoMAP: Co-Evolving World Models and Agent Policies for LLM Agents

Youwei Liu, Jian Wang†, Hanlin Wang, Wenjie Li

Overview

Figure 1. Conceptual illustration of CoMAP.
CoMAP co-evolves the world model and the agent policy in a closed loop. The world model provides lookahead states for policy improvement, while the agent policy generates on-policy interactions for world-model updating.
