WorldMemBench contains 200 static-memory cases and 60 dynamic-memory cases across 23 semantic categories.
Benchmark exposes separate static and dynamic memory failures in video worlds
WorldMemBench tests whether generated worlds preserve people, objects, environments and evolving events across repeated departures and returns.

Zhou and colleagues introduce a 260-case benchmark that evaluates memory in video world models using controlled camera departures, repeated revisits and off-screen events.
Why this paper
From Ant Group and 3 others
In one line
WorldMemBench evaluates video world models on static and dynamic memory retention across repeated revisits, finding no model leads all dimensions.
