OTCache framework accelerates diffusion models using Optimal Transport

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced OTCache, a novel framework designed to accelerate diffusion models by predicting optimal caching schedules. This method utilizes Optimal Transport (OT) principles to model the evolution of caching policies across different inference budgets, addressing limitations of existing graph-based approaches. OTCache achieves significant speedups, ranging from 3.66x to 4.7x, on models like FLUX.1, Qwen-Image, and HunyuanVideo, while also enhancing generation fidelity compared to current state-of-the-art methods.

    OTCache: Optimal Transport for Geometry-Aware Caching in Diffusion Models

    arXiv:2606.31026v1 Announce Type: cross Abstract: We propose OTCache, a training-free framework for accelerating diffusion sampling via caching schedule prediction. Existing graph-based caching methods reduce redundant computation by optimizing shortest-path objectives, but rely …
