From Local Mismatch to Global Impact: Optimizing Cache Reuse Policy for Efficient Diffusion

Diffusion models have achieved dominant performance in visual generation but suffer from substantial inference overhead. While cache-based acceleration has emerged as a promising solution, existing policies rely on local similarity heuristics, which we identify as being significantly misaligned with final generation qu...

OnlineCache: Learning Dynamic Caching Policies with Error Correction for Efficient Diffusion Inference

This paper proposes OnlineCache, a dynamic caching framework that jointly learns when to cache and how to correct approximation errors, and leverages policy gradient to train a lightweight network for adaptive speed-quality trade-offs, and incorporate a learnable corrector to mitigate caching-induced errors.
