HyperVAttention: Efficient Sparse Attention with Spatio-Temporal Clustering for Video Diffusion

arXiv:2607.03012v1 Announce Type: cross Abstract: Video Diffusion Transformers (VDiTs) have demonstrated significant capabilities in high-fidelity video generation. However, their ability to produce long-duration videos is fundamentally constrained by the quadratic complexity of the self-attention mechanism. Recent clustering-based sparse attention methods improve the quality-speed trade-off by grouping semantically similar tokens, but their practical efficiency remains limited by two bottlenecks: substantial clustering overhead and low CTA utilization caused by irregular cluster-induced block
The explosion of interest in generative AI, particularly video generation, is driving fundamental research into overcoming computational bottlenecks for practical applications.
Efficient video diffusion models can unlock new applications in media creation, autonomous systems, and synthetic data generation, expanding the reach and utility of generative AI.
The computational barrier to generating longer, higher-fidelity videos will be reduced, making video diffusion more accessible and scalable for various industries.
