            This leaderboard showcases performance metrics across different types of AI models in world modeling tasks:
            
            ## Model Categories
            - **VLM**: Vision-Language Models
            - **Image Gen.**: Image Generation Models  
            - **Video Gen.**: Video Generation Models
            - **Video Gen. Post-Train**: Post-training specialized Video Generation Models
            
            ## Metrics Explained
            - **Acc. ↑**: Accuracy score (higher values indicate better performance)
            - **Mean Traj. ↓**: Mean trajectory error (lower values indicate better performance)
            
            ## Notes
            - † indicates post-training specialized models
            - XXX indicates results pending/unavailable
            - – indicates not applicable or not available
            
            *Results represent performance on world modeling evaluation benchmarks and may vary across different evaluation settings.*
