A new research paper introduces MSSR (Minimal Sufficient Spatial Reasoner), a dual-agent framework that improves Vision-Language Models' ability to reason about 3D spatial relationships. The method addresses two key bottlenecks: inadequate 3D understanding from 2D-centric training and reasoning failures from redundant information.

Researchers have introduced PERSIST, a new world model paradigm that explicitly represents 3D environment state rather than learning 3D consistency implicitly from video data. The approach maintains persistent spatial memory and geometric consistency across extended generation horizons, addressing a core limitation of existing interactive video models that lack explicit 3D representations.
