Light Interaction introduces a training-free inference acceleration framework for interactive video world models, using adaptive context management, denoising cache acceleration, and 3D block sparse attention to achieve up to 2.59x speedup while maintaining competitive visual quality.
Incantation presents an interactive video world model that uses natural language as the action interface for fine-grained multi-entity control and cross-entity generalization, achieving high performance and real-time streaming through novel attention and distillation techniques.
Echo-Forcing introduces a scene memory framework for interactive long video generation, using hierarchical temporal memory, scene recall frames, and difference-aware memory decay to handle prompt switching and long-term recall. The method is training-free and achieves strong performance on VBench-Long.
