## Summary

WorldArena 2.0 has been released, expanding embodied world model evaluation along three dimensions: modality, functionality, and platform. In modality, it extends from vision-only to visuotactile; in functionality, it extends beyond policy evaluation and planning to using world models as interactive reinforcement learning environments for policy optimization; in platform, it extends from simulation-only to multiple simulators and real robot embodiments. The benchmark evaluates perception quality, interaction utility, and cross-platform performance under a unified protocol, and the project page provides code and demos.
