Beyond Next-Observation Prediction: Agent-Authored World Modeling for Sequential Decision Making

arXiv:2606.25421v1 Announce Type: new Abstract: Recent studies on world modeling for Large Language Model (LLM) agents typically formulate the learning objective as next-observation prediction. However, this objective ties supervision to what a transition happens to reveal, which may omit the dynamics most relevant to the agent's current decision. To bridge this gap, we propose Agent-Authored World Modeling (AAWM), a training procedure that constructs supervision from the policy's own decision needs. Specifically, at each state, the agent identifies what it needs to understand about the enviro

Why this matters
Why now

This research addresses a current limitation in LLM agent world modeling, where next-observation prediction may not align with an agent's true decision-making needs, suggesting a refinement in training methodologies.

Why it’s important

Improving how AI agents understand and interact with their environment accelerates their autonomous capabilities, crucial for broader enterprise and strategic applications.

What changes

The focus shifts from general prediction to agent-centric, policy-driven world modeling, potentially leading to more efficient and effective AI agent development.
