Individual components of diffusion pipelines are usually trained individually, so we suggest to directly work with [`UNetModel`] and [`UNetConditionModel`]. </Tip> Any diffusion pipeline that is loaded with [`~DiffusionPipeline.from_pretrained`] will automatically detect the pipeline type, *e.g.* [`StableDiffusionPipeline`] and consequently load each component of the pipeline and pass them into the `__init__` function of the pipeline, *e.g.* [`~StableDiffusionPipeline.__init__`]. Any pipeline object can be saved locally with [`~DiffusionPipeline.save_pretrained`]. ## DiffusionPipeline [[autodoc]] DiffusionPipeline - all - __call__ - device - to - components ## ImagePipelineOutput By default diffusion pipelines return an object of class [[autodoc]] pipelines.ImagePipelineOutput ## AudioPipelineOutput By default diffusion pipelines return an object of class [[autodoc]] pipelines.AudioPipelineOutput
