Abstract
WorldMemBench is a benchmark for systematically evaluating world memory in video world models, focusing on both static and dynamic memory retention.
Reality Card
Core Claim
WorldMemBench provides a systematic testbed for diagnosing memory failures and guiding the development of persistent, temporally coherent video worlds.
Method / Result
Evaluated nine representative models, revealing that strong static retention does not imply reliable dynamic state evolution.
Limitations
The study indicates that memory degradation occurs beyond the first return, which may complicate reproducibility in dynamic scenarios.
