ResilPhase: Plug-and-Play Phase Mapping and Noise-Resilient Macro-Trajectory Extrapolation for Diffusion Acceleration
Summary
ResilPhase is a novel acceleration framework designed to mitigate the significant inference latency of powerful diffusion models. It addresses the quality degradation observed in existing "cache-then-forecast" schemes, which suffer from discrete extrapolation on misaligned and unstable representations, causing accumulated spatial errors and noisy derivative amplification. ResilPhase reformulates accelerated inference as stable macro-trajectory extrapolation within ordinary differential equation (ODE) space. It aligns forecasting with the model's Global Drift (GD), an end-to-end state evolution, to resolve feature inconsistency and memory overhead. To counter the "derivative fallacy" of noisy higher-order temporal derivatives, the framework employs a derivative-free barycentric Lagrange extrapolator. Additionally, a bounded Phase Mapping regularizes the extrapolation domain, effectively suppressing oscillatory error growth. Experiments on FLUX.1-dev and HunyuanVideo demonstrate ResilPhase's ability to achieve state-of-the-art fidelity even under aggressive acceleration ratios.
Key takeaway
For Machine Learning Engineers optimizing diffusion model inference, ResilPhase offers a robust solution to achieve aggressive acceleration without compromising output quality. If your current "cache-then-forecast" methods suffer from fidelity degradation, you should investigate adopting ResilPhase's approach of stable macro-trajectory extrapolation. This framework, by aligning forecasting with Global Drift and employing derivative-free methods, can significantly reduce latency for models like FLUX.1-dev and HunyuanVideo, enhancing deployment efficiency for high-performance applications.
