Introducing Modular Diffusers - Composable Building Blocks for Diffusion Pipelines

AnnouncementProductMar 5, 2026

Hugging Face introduced Modular Diffusers, a composable system for building diffusion pipelines from reusable blocks, complementing the existing DiffusionPipeline class. Developed by YiYi Xu, Alvaro Somoza, Dhruv Nair, and Sayak Paul, the framework allows users to inspect, add, remove, and swap individual pipeline blocks such as text encoding and denoising. Custom blocks can be written and integrated into workflows, with support for Mellon, a node-based visual interface for connecting blocks.
