BLADE: Block-Sparse Attention Meets Step Distillation for Efficient Video Generation

Youping Gu, XIAOLONG LI, Yuhao Hu, Chen Minqi, Bohan Zhuang

ICLR 2026poster

Diffusion transformers currently lead the field in high-quality video generation, but their slow iterative denoising process and prohibitive quadratic attention costs for long sequences create significant inference bottlenecks. While both step distillation and sparse attention mechanisms have shown…

World-R1: Reinforcing 3D Constraints for Text-to-Video Generation

Weijie Wang, Xiaoxuan He, Youping Gu, Zeyu Zhang, Yefei He, Yanbo Ding +6

ICML 2026poster

Recent video foundation models demonstrate impressive visual synthesis but frequently suffer from geometric inconsistencies. While existing methods attempt to inject 3D priors via architectural modifications, they often incur high computational costs and limit scalability. We propose World-R1, a fra…
