Dynamic 4D Spatial Reasoning
Extends static 3D spatial reasoning by introducing a temporal dimension, requiring a model to understand how a scene evolves over time, including object movement, trajectory extension, occlusion changes and the ordering of events.

There is a pronounced "spatial–dynamic interference" phenomenon between static 3D spatial understanding and dynamic 4D scene reasoning: post-training on 3D tasks weakens a model's ability to understand dynamic scenes, while models specialized in 4D reasoning often lack a solid foundation in static 3D spatial reasoning.
Dynamic 4D spatial reasoning requires a model to understand how a scene evolves over time, including object movement, trajectory extension, changes in occlusion relationships and the temporal ordering of events among multiple entities.
DynThinker demonstrates that static 3D and dynamic 4D capabilities can simultaneously reach leading levels in the same model, rather than necessarily trading one for the other.
