New method calibrates language agents' world models via environment probing

Researchers have developed a new method called \method for language agents that allows them to calibrate their internal world models by probing the environment. This approach treats environment interaction as a scarce resource for model calibration, rather than just a means to advance a task. The system is designed to help agents repair their world models by asking about specific belief fields before committing to actions, particularly useful for procedural beliefs like tool dependencies and spatial beliefs like object locations. Experiments show that this mid-planning evidence reduces world-model errors when the probing strategy aligns with the task structure. AI

IMPACT Introduces a novel approach to improve the reliability and accuracy of long-horizon language agents by enabling them to actively calibrate their internal world models.

    Ask the World Before Acting: Budgeted Environment Probing for World-Model Calibration

    arXiv:2606.31422v1 Announce Type: new Abstract: Long-horizon language agents do not only choose actions; they carry a private model of the world from one decision to the next. When that model drifts, a later failure can be decided before the failing action is ever taken. We study…
