WorldAgen: Unified State-Action Prediction with Test-Time World Model Training

Chi Wan, Kangrui Wang, Yuan Si +2

How can vision-language-action (VLA) models adapt to new environments where world dynamics shift? While recent research has combined world modeling and action prediction to improve…

Planning with the Views

Kangrui Wang, Linjie Li, Zhengyuan Yang +7

Can VLMs predict how each camera move changes the view, and plan many such moves ahead? We call this capability view planning, requiring (1)understanding how a single action transf…

Why Do LLM Agents Fail in Exploring New Environments? A World-Modeling Perspective

Shiqi Chen, Tongyao Zhu, Zian Wang +8

Large Language Models (LLMs) as agents often fail to improve in new environments. We identify and characterize a failure mode we call exploration collapse: under reinforcement lear…

MindCube: Spatial Mental Modeling from Limited Views

Qineng Wang, Baiqiao Yin, Pingyue Zhang +11

Can Vision-Language Models (VLMs) imagine the full scene from just a few views, like humans do? Humans form spatial mental models naturally, internal representations of unseen spac…
