This is a fork of SD:Next with the goal of providing the best out-of-box experience for Navi 31 (and Navi 3x).

See What is this? for detail.

Top-13 Features (10 wasn't enough)

All Individual features are not listed here, instead check ChangeLog for full list of changes.

• Optimized processing with latest torch developments
  Including built-in support for torch.compile
• Support for multiple backends!
  original and diffusers
• Support for multiple diffusion models!
  Stable Diffusion, SD-XL, Kandinsky, DeepFloyd IF, etc.
• Fully multiplatform with platform specific autodetection and tuning performed on install
  Windows / Linux / MacOS with CPU / nVidia / AMD / IntelArc / DirectML
• Improved prompt parser
• Enhanced Lora/Locon/Lyco code supporting latest trends in training
• Built-in queue management
• Advanced metadata caching and handling to speed up operations
• Enterprise level logging and hardened API
• Modern localization and hints engine
• Broad compatibility with existing extensions ecosystem and new extensions manager
• Built in installer with automatic updates and dependency management
• Modernized UI (still based on Gradio) with theme support

Backend support

SD.Next supports two main backends: Original and Diffusers which can be switched on-the-fly:

• Original: Based on LDM reference implementation and significantly expanded on by A1111
  This is the default backend and it is fully compatible with all existing functionality and extensions
• Diffusers: Based on new Huggingface Diffusers implementation
  It is also the only backend that supports Stable Diffusion XL model
  Support for legacy workflows and extensions is limited, but it's being expanded
  See wiki article for more information

Model support

Additional models will be added as they become available and there is public interest in them

• Stable Diffusion 1.x and 2.x including all variants
• Stable Diffusion XL
• Kandinsky 2.1
• DeepFloyd IF
• UniDiffusion

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
• Any GPU compatibile with DirectX on Windows using DirectML libraries.
  This includes support for AMD GPUs that are not supported by native ROCm libraries
• Intel Arc GPUs using Intel OneAPI Ipex/XPU libraries
• Apple M1/M2 on OSX using built-in support in Torch with MPS optimizations

Install & Run

• Step-by-step install guide
• Advanced install notes

Installation Notes

• Common installation errors
• FAQ
• Server can run without virtual environment,
  but it is recommended to use it to avoid library version conflicts with other applications
• nVidia/CUDA and AMD/ROCm are auto-detected if present and available,
  but for any other use case specify required parameter explicitly or wrong packages may be installed
  as installer will assume CPU-only environment
• Full startup sequence is logged in sdnext.log, so if you encounter any issues, please check it first

Run

Once SD.Next is installed, simply run webui.bat (Windows) or webui.sh (Linux or MacOS)

Below is partial list of all available parameters, run webui --help for the full list:

  --use-cuda                       Force use nVidia CUDA backend, default: False
  --use-rocm                       Force use AMD ROCm backend, default: False
  --skip-update                    Skip update of extensions and submodules, default: False
  --skip-requirements              Skips checking and installing requirements, default: False
  --skip-extensions                Skips running individual extension installers, default: False
  --skip-git                       Skips running all GIT operations, default: False
  --skip-torch                     Skips running Torch checks, default: False
  --reinstall                      Force reinstallation of all requirements, default: False
  --debug                          Run installer with debug logging, default: False
  --reset                          Reset main repository to latest version, default: False
  --upgrade                        Upgrade main repository to latest version, default: False
  --safe                           Run in safe mode with no user extensions

Notes

Extensions

SD.Next comes with several extensions pre-installed:

• Dynamic Thresholding
• ControlNet
• Agent Scheduler
• Multi-Diffusion Tiled Diffusion and VAE
• LyCORIS
• Image Browser
• CLiP Interrogator
• Rembg Background Removal

Collab

• To avoid having this repo rely just on me, I'd love to have additional maintainers with full admin rights. If you're interested, ping me!
• 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 I would really love to have additional contributors and/or maintainers to join and help lead the efforts on different platforms.

Goals

The idea behind the fork is to enable latest technologies and advances in text-to-image generation.

Sometimes this is not the same as "as simple as possible to use".

If you are looking an amazing simple-to-use Stable Diffusion tool, I'd suggest InvokeAI specifically due to its automated installer and ease of use.

General goals:

• Cross-platform
  • Create uniform experience while automatically managing any platform specific differences
• Performance
  • Enable best possible performance on all platforms
• Ease-of-Use
  • Automatically handle all requirements, dependencies, flags regardless of platform
  • Integrate all best options for uniform out-of-the-box experience without the need to tweak anything manually
• Look-and-Feel
  • Create modern, intuitive and clean UI
• Up-to-Date
  • Keep code up to date with latest advanced in text-to-image generation
