Think Like a World Model, Act Like a VLA: Distilling World-Model Representations into Compact Robot Policies

arXiv 2026 22.7 method, application

TLDR

Distills frozen world-model representations into compact VLA policies via feature alignment, improving LIBERO and RoboCasa benchmarks and real robots while maintaining 32 ms inference.

Reasoning

The paper presents a practical method to transfer world-model grounding to robot policies without generative inference, with solid experiments across benchmarks and real hardware. Weaknesses: limited visibility into method details and failure cases from the abstract; the exact mechanism by which alignment transfers grounding is only asserted.
