New pipelines

Untitled

This release features many new pipelines. Below, we provide a list:

Audio pipelines 🎼

Video pipelines 📹

Image pipelines 🎇

Be sure to check out the respective docs to know more about these pipelines. Some additional pointers are below for curious minds:

  • Lumina introduces a new DiT architecture that is multilingual in nature.
  • Kolors is inspired by SDXL and is also multilingual in nature.
  • Flux introduces the largest (more than 12B parameters!) open-sourced DiT variant available to date. For efficient DreamBooth + LoRA training, we recommend @bghira’s guide here.
  • We have worked on a guide that shows how to quantize these large pipelines for memory efficiency with optimum.quanto. Check it out here.
  • CogVideoX introduces a novel and truly 3D VAE into Diffusers

Perturbed Attention Guidance (PAG)

Without PAG With PAG

We already had community pipelines for PAG, but given its usefulness, we decided to make it a first-class citizen of the library. We have a central usage guide for PAG here, which should be the entry point for a user interested in understanding and using PAG for their use cases. We currently support the following pipelines with PAG:

  • StableDiffusionPAGPipeline
  • StableDiffusion3PAGPipeline
  • StableDiffusionControlNetPAGPipeline
  • StableDiffusionXLPAGPipeline
  • StableDiffusionXLPAGImg2ImgPipeline
  • StableDiffusionXLPAGInpaintPipeline
  • StableDiffusionXLControlNetPAGPipeline
  • StableDiffusion3PAGPipeline
  • PixArtSigmaPAGPipeline
  • HunyuanDiTPAGPipeline
  • AnimateDiffPAGPipeline
  • KolorsPAGPipeline

If you’re interested in helping us extend our PAG support for other pipelines, please check out this thread.
Special thanks to Ahn Donghoon (@sunovivid), the author of PAG, for helping us with the integration and adding PAG support to SD3.

AnimateDiff with SparseCtrl

SparseCtrl introduces methods of controllability into text-to-video diffusion models leveraging signals such as line/edge sketches, depth maps, and RGB images by incorporating an additional condition encoder, inspired by ControlNet, to process these signals in the AnimateDiff framework. It can be applied to a diverse set of applications such as interpolation or video prediction (filling in the gaps between sequence of images for animation), personalized image animation, sketch-to-video, depth-to-video, and more. It was introduced in **SparseCtrl: Adding Sparse Controls to Text-to-Video Diffusion Models.**

There are two SparseCtrl-specific checkpoints and a Motion LoRA made available by the authors namely:

FreeNoise for AnimateDiff

FreeNoise is a training-free method that allows extending the generative capabilities of pretrained video diffusion models beyond their existing context/frame limits.

Instead of initializing noises for all frames, FreeNoise reschedules a sequence of noises for long-range correlation and performs temporal attention over them using a window-based function. We have added FreeNoise to the AnimateDiff family of models in Diffusers, allowing them to generate videos beyond their default 32 frame limit.

LoRA refactor

We have significantly refactored the loader classes associated with LoRA. Going forward, this will help in adding LoRA support for new pipelines and models. We now have a LoraBaseMixin class which is subclassed by the different pipeline-level LoRA loading classes such as StableDiffusionXLLoraLoaderMixin. This document provides an overview of the available classes.

Additionally, we have increased the coverage of methods within the PeftAdapterMixin class. This refactoring allows all the supported models to share common LoRA functionalities such set_adapter(), add_adapter(), and so on.

To learn more details, please follow this PR. If you see any LoRA-related issues stemming from these refactors, please open an issue.

🚨 Fixing attention projection fusion

We discovered that the implementation of fuse_qkv_projections() was broken. This was fixed in this PR. Additionally, this PR added the fusion support to AuraFlow and PixArt Sigma. A reasoning as to where this kind of fusion might be useful is available here.
