Meituan LongCat Team Unveils WBench: The First Systematic Benchmark for Interactive Video World Models

The Meituan LongCat team has officially announced the release and open-sourcing of WBench, a pioneering evaluation framework designed to measure the performance of interactive video world models. As the first systematic multi-round evaluation benchmark of its kind, WBench functions as a diagnostic "CT scanner" for artificial intelligence. It is specifically engineered to identify the technical bottlenecks that occur as world models transition from "passive viewing"—simply observing data—to "active interaction," where models must respond to and manipulate environments. This release marks a significant step in standardizing how the industry evaluates the boundaries and capabilities of complex world models in dynamic, multi-stage scenarios.
