Overview

Modular Diffusers is a unified pipeline system that simplifies your workflow with pipeline blocks.

• Blocks are reusable and you only need to create new blocks that are unique to your pipeline.
• Blocks can be mixed and matched to adapt to or create a pipeline for a specific workflow or multiple workflows.

The Modular Diffusers docs are organized as shown below.

Quickstart

• The quickstart shows you how to run a modular pipeline, understand its structure, and customize it by modifying the blocks that compose it.
• Coming from DiffusionPipeline lists what works differently from a DiffusionPipeline, for readers who know the standard pipelines.

ModularPipelineBlocks

• States explains how data is shared and communicated between blocks and ModularPipeline.
• ModularPipelineBlocks is the most basic unit of a ModularPipeline and this guide shows you how to create one.
• SequentialPipelineBlocks is a type of block that chains multiple blocks so they run one after another, passing data along the chain. This guide shows you how to create SequentialPipelineBlocks and how they connect and work together.
• LoopSequentialPipelineBlocks is a type of block that runs a series of blocks in a loop. This guide shows you how to create LoopSequentialPipelineBlocks.
• AutoPipelineBlocks is a type of block that automatically chooses which blocks to run based on the input. This guide shows you how to create AutoPipelineBlocks.
• Building Custom Blocks shows you how to create your own custom blocks and share them on the Hub.

ModularPipeline

• ModularPipeline shows you how to create and convert pipeline blocks into an executable ModularPipeline.
• ComponentsManager shows you how to manage and reuse components across multiple pipelines.
• Guiders shows you how to use different guidance methods in the pipeline.

Mellon Integration

• Using Custom Blocks with Mellon shows you how to make your custom blocks work with Mellon, a visual node-based interface for building workflows.
