Compress to Remember: Learning Compact Memory via On-Policy Distillation for Long Video Generation

Standard video generators do not natively compact historical context into reusable memory tokens. As generation continues, the growing history makes it increasingly difficult to retain information from earlier frames due to long-context degradation. Key-frame-based approaches address this challenge by retaining selecte...

EchoCache: Energy-Guided Cross-Modal Caching for Efficient Audio-Driven Video Generation

EchoCache is proposed, an energy-guided cross-modal caching framework for efficient A2V generation that leverages audio time-frequency energy as a saliency anchor to guide latent-level cache updates and further introduces a dynamic timestep-latent caching mechanism with quantized cache management for joint efficiency a...
