ComfyUI-ZImageTurbo-FlowSampler

FlowMatchScheduler

Generic flow-matching scheduler with shift support. For Flux, SD3, and other flow-matching models. NOTE: For Z-Image-Turbo, use shift=1.0 (or use ZImageTurboScheduler instead).

ZImageSampler

Clean Euler sampler for Rectified Flow / Flow Matching. Uses the interpolation formula which is more numerically stable than the Karras ODE formulation used in ComfyUI's default euler.
