Efficient Long-Context Modeling in Diffusion Language Models via Block Approximate Sparse Attention

Wenhu Zhang, Yiming Wu, Huanyu Wang, Yaoyang Liu, Huanzhang Dou, Senqiao Yang, Sitong Wu, Hanbin Zhao, Jiaya Jia

CVPR Findings 2026

We propose BA-Att, a block approximate sparse attention framework with pre-downsampling and covariance-compensated correction, achieving up to 6.95× speedup over FlashAttention at 50% sparsity across language, multimodal, and video generation models.

SwiftI2V: Efficient High-Resolution Image-to-Video Generation via Conditional Segment-wise Generation

Yaoyang Liu, Yuechen Zhang, Wenbo Li, Yufei Zhao, Rui Liu, Long Chen

Preprint 2026

We propose SwiftI2V, an efficient framework for high-resolution (2K) I2V generation that decouples motion modeling from detail synthesis via progressive segment-wise generation and bidirectional contextual interaction. SwiftI2V achieves performance comparable to end-to-end baselines while reducing total GPU-time by 202×, enabling practical 2K I2V on a single RTX 4090.
