New ScalingAttention framework boosts Diffusion Transformer video generation

Researchers have developed ScalingAttention, a novel framework designed to optimize video generation using Diffusion Transformers (DiTs). This method addresses the computational bottleneck caused by full 3D attention in DiTs by discovering an intrinsic sparse attention topology that is prompt-agnostic and stable during training. The framework utilizes WEST for offline extraction of a block-sparse prior mask and FAST for adaptive head-wise sparsity tuning, leading to significant speedups and improved fidelity in video generation tasks.
