WorldExam tests video models for world reactivity
The benchmark evaluates whether controllable video models infer plausible consequences from scene state.
Why it matters
The work argues that evaluating video models as world models requires more than visual quality or instruction following. It gives researchers a structured way to test whether generated environments behave plausibly under implicit conditions.
The key points
- 1.WorldExam covers 1,474 cases across eight tasks.
- 2.It evaluates visual quality, control, spatial consistency, and reactivity.
- 3.Twenty models showed a split between control strengths and reactivity limits.
Researchers introduced WorldExam, a hierarchical diagnostic benchmark for evaluating controllable video generation models as world models. The benchmark includes 1,474 cases across eight tasks and measures four levels: Visual Quality, Control Adherence, Spatial Consistency, and World Reactivity. Its World Reactivity level tests whether models can generate scene-conditioned reactions and goal-directed behaviors beyond what is explicitly specified in the input. An evaluation of 20 representative models found a capability split, with camera-driven models excelling at camera control while lacking interfaces for some reactivity tests.
