Research Paper Overview
Less is Enough: Training-Free Video Diffusion Acceleration via Runtime-Adaptive Caching
Summary
This paper introduces EasyCache, a training-free acceleration framework for video diffusion models that dynamically reuses previously computed transformation vectors during inference to reduce redundant computations. It achieves 2.1-3.3× faster inference and up to 36% PSNR improvement over prior methods without offline profiling or parameter tuning, enabling efficient, high-quality video generation.
