OmniCache: Multidimensional Hierarchical Feature Caching For Diffusion Models
OmniCache is proposed, a unified hierarchical caching framework that performs multidimensional feature reuse through Token Cache, Frame Cache, Block Cache, and Layered Cache that reuses spatial features in temporal layers and temporal features in spatial layers, while Layered Cache captures cross-step redundancy at the model-layer level.
