Koala Yoran

Koala Yoran (考拉悠然) says its Youran Wujie World Model took second place overall in the video-quality track of the WorldArena 2.0 ranking announced on September 16, and placed first on two core metrics: Background Consistency and JEPA Similarity. The evaluation pooled 80 models from Alibaba, the Chinese Academy of Sciences, and embodied-AI companies, testing video generation quality, temporal consistency, and physical evolution. The model uses structured 4D world modeling and dynamic scene memory, and is combined with the Geek Mind embodied brain on a quadruped robot to provide industrial inspection for workshops of large central state-owned enterprises.
