| # Overview |
|
|
| > [!WARNING] |
| > Modular Diffusers is under active development and it's API may change. |
|
|
| 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](./quickstart) shows you how to run a modular pipeline, understand its structure, and customize it by modifying the blocks that compose it. |
|
|
| ## ModularPipelineBlocks |
|
|
| - [States](./modular_diffusers_states) explains how data is shared and communicated between blocks and [`ModularPipeline`]. |
| - [ModularPipelineBlocks](./pipeline_block) is the most basic unit of a [`ModularPipeline`] and this guide shows you how to create one. |
| - [SequentialPipelineBlocks](./sequential_pipeline_blocks) 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 [`~modular_pipelines.SequentialPipelineBlocks`] and how they connect and work together. |
| - [LoopSequentialPipelineBlocks](./loop_sequential_pipeline_blocks) is a type of block that runs a series of blocks in a loop. This guide shows you how to create [`~modular_pipelines.LoopSequentialPipelineBlocks`]. |
| - [AutoPipelineBlocks](./auto_pipeline_blocks) is a type of block that automatically chooses which blocks to run based on the input. This guide shows you how to create [`~modular_pipelines.AutoPipelineBlocks`]. |
| - [Building Custom Blocks](./custom_blocks) shows you how to create your own custom blocks and share them on the Hub. |
|
|
| ## ModularPipeline |
|
|
| - [ModularPipeline](./modular_pipeline) shows you how to create and convert pipeline blocks into an executable [`ModularPipeline`]. |
| - [ComponentsManager](./components_manager) shows you how to manage and reuse components across multiple pipelines. |
| - [Guiders](../using-diffusers/guiders) shows you how to use different guidance methods in the pipeline. |
|
|
| ## Mellon Integration |
|
|
| - [Using Custom Blocks with Mellon](./mellon) shows you how to make your custom blocks work with [Mellon](https://github.com/cubiq/Mellon), a visual node-based interface for building workflows. |
