FlowMapEulerDiscreteScheduler

FlowMapEulerDiscreteScheduler is an Euler-style sampler designed for flow-map-distilled diffusion models. Flow-map models learn arbitrary-interval transitions $\mathbf{z}_t \to \mathbf{z}_r$ rather than the fixed $\mathbf{z}_t \to \mathbf{z}_0$ mapping of consistency models. Both endpoints of the step are caller-provided, which is what enables any-step sampling: a single distilled checkpoint can be evaluated at 1, 2, 4, 8, 16... NFE without retraining.

The scheduler was introduced in AnyFlow: Any-Step Video Diffusion Model with On-Policy Flow Map Distillation and ships with the AnyFlowPipeline and AnyFlowFARPipeline integrations, but it is not AnyFlow-specific — any flow-map-distilled checkpoint can use it.
