RA-CFGCache: Risk-Aligned Caching for CFG-Guided Diffusion Models

RA-CFGCache introduces a risk-aligned caching framework for classifier-free guided diffusion models that jointly models cross-branch error alignment and timestep-dependent error propagation, achieving superior efficiency-fidelity trade-offs on FLUX.1-dev, Wan2.1, and CogVideoX while remaining compatible with existing cache estimators.
