Platform support

• nVidia GPUs using CUDA libraries on both Windows and Linux
• AMD GPUs using ROCm libraries on Linux
  Support will be extended to Windows once AMD releases ROCm for Windows
• Intel Arc GPUs using OneAPI with IPEX XPU libraries on both Windows and Linux
• Any GPU compatible with DirectX on Windows using DirectML libraries
  This includes support for AMD GPUs that are not supported by native ROCm libraries
• Any GPU or device compatible with OpenVINO libraries on both Windows and Linux
• Apple M1/M2 on OSX using built-in support in Torch with MPS optimizations
• ONNX/Olive
• AMD GPUs on Windows using ZLUDA libraries

Getting started

• Get started with SD.Next by following the installation instructions
• For more details, check out advanced installation guide
• List and explanation of command line arguments
• Install walkthrough video

Tip

And for platform specific information, check out
WSL | Intel Arc | DirectML | OpenVINO | ONNX & Olive | ZLUDA | AMD ROCm | MacOS | nVidia

Warning

If you run into issues, check out troubleshooting and debugging guides

Tip

All command line options can also be set via env variable For example --debug is same as set SD_DEBUG=true

Backend support

SD.Next supports two main backends: Diffusers and Original:

• Diffusers: Based on new Huggingface Diffusers implementation
  Supports all models listed below
  This backend is set as default for new installations
• Original: Based on LDM reference implementation and significantly expanded on by A1111
  This backend and is fully compatible with most existing functionality and extensions written for A1111 SDWebUI
  Supports SD 1.x and SD 2.x models
  All other model types such as SD-XL, LCM, Stable Cascade, PixArt, Playground, Segmind, Kandinsky, etc. require backend Diffusers

Collab

• We'd love to have additional maintainers (with comes with full repo rights). If you're interested, ping us!
• In addition to general cross-platform code, desire is to have a lead for each of the main platforms
  This should be fully cross-platform, but we'd really love to have additional contributors and/or maintainers to join and help lead the efforts on different platforms

Credits

• Main credit goes to Automatic1111 WebUI for original codebase
• Additional credits are listed in Credits
• Licenses for modules are listed in Licenses
