# Consistency Model Multistep Scheduler## OverviewMultistep and onestep scheduler (Algorithm 1) introduced alongside consistency models in the paper [Consistency Models](https://arxiv.org/abs/2303.01469) by Yang Song, Prafulla Dhariwal, Mark Chen, and Ilya Sutskever.Based on the [original consistency models implementation](https://github.com/openai/consistency_models).Should generate good samples from [`ConsistencyModelPipeline`] in one or a small number of steps.## CMStochasticIterativeScheduler[[autodoc]] CMStochasticIterativeScheduler
