Sygil-webui provides a comprehensive, browser-based interface for Stable Diffusion, catering to artists, researchers, and hobbyists. It simplifies the process of generating and refining images through text prompts, offering advanced features for control and upscaling, and aims to be accessible even on lower-end hardware.

How It Works

The project offers two primary UI frameworks: Streamlit and Gradio. The Streamlit UI is actively developed, featuring a clean design, dynamic previews, and VRAM optimization. The Gradio UI is a legacy, feature-complete interface receiving only bug fixes. Both UIs leverage Stable Diffusion's latent diffusion model for text-to-image generation, incorporating various K-Diffusion samplers and advanced prompt weighting for fine-grained control.

Quick Start & Requirements

• Installation instructions are provided for Windows and Linux.
• Requires Python and potentially CUDA for GPU acceleration.
• Specific upscaler models (GFPGAN, RealESRGAN, LSDR) need to be downloaded and placed in designated directories.
• Documentation is available at https://github.com/Sygil-Dev/sygil-webui/tree/main/docs.

Highlighted Details

• Supports built-in image enhancers and upscalers like GFPGAN and RealESRGAN.
• Features Textual Inversion for custom embeddings and training.
• Includes advanced img2img editing with mask painting and cropping capabilities.
• Offers prompt weighting, negative prompts, and prompt matrix generation for enhanced control.
• Optimized for lower VRAM usage, with 512x512 generation tested on 4GB VRAM.

Maintenance & Community

• Active development by Sygil.Dev main developers.
• Community support and feature requests via Discord server and GitHub Discussions.
• Contribution Guide available for interested developers.

Licensing & Compatibility

• The README does not explicitly state a license. The underlying Stable Diffusion model is based on research from Stability AI and Runway, with code building on OpenAI's ADM codebase and lucidrains' denoising-diffusion-pytorch. Compatibility for commercial use or closed-source linking is not specified.

Limitations & Caveats

• The Gradio interface is no longer actively developed by Sygil.Dev.
• Text-to-Video generation is marked as Work-In-Progress (WIP).
• Some advanced features like ImgLab, batch inputs, and mask editor are currently only available in the Gradio version.
