When and How Much to Imagine: Adaptive Test-Time Scaling with World Models for Visual Spatial Reasoning
arXiv:2602.08236v2 Announce Type: replace-cross Abstract: Despite rapid progress in MLLMs, visual spatial reasoning remains unreliable when correct answers depend on how a scene would appear under unseen or alternative viewpoints. Recent work addresses this by augmenting reasoning with world models for visual imagination, but questions such as when imagination is actually necessary, how much of it is beneficial, and when it becomes harmful, remain poorly understood. In practice, indiscriminate imagination can increase computation and even degrade performance by introducing misleading evidence.
The rapid progress in MLLMs and a push for more robust AI applications necessitate solving critical efficiency and reliability challenges in visual reasoning, particularly under varying viewpoints.
Improving visual spatial reasoning is crucial for advanced AI agents and robotics to operate effectively and reliably in complex, real-world environments, reducing computational overhead and errors.
This research outlines a method for more adaptive and efficient use of 'imagination' in AI, moving towards more reliable and less computationally intensive visual reasoning processes.
