Gauss is a native macOS application for generating images using Stable Diffusion, built with SwiftUI and Apple's CoreML models. It targets macOS users seeking a streamlined, local image generation experience, storing all generated images within document-based .gaussnb files for easy management and export.

How It Works

Gauss leverages Apple's ml-stable-diffusion CoreML models, enabling native execution on macOS, including Apple Silicon. This approach aims for better performance and integration compared to Electron-based alternatives by avoiding cross-platform overhead and utilizing optimized CoreML frameworks. The document-based architecture allows for organized storage and retrieval of prompts and generated images.

Quick Start & Requirements

• Install: Download the latest release from the releases page.
• Prerequisites: macOS 13.1+, Xcode 14.2+ (for development). Recommended: Apple Silicon CPU.
• Models: Requires downloading Stable Diffusion models (approx. 2.5GB each).
• Disk Space: At least 10GB free.
• git-lfs: Required for fetching models. Install via brew install git-lfs or download from git-lfs.github.com.

Highlighted Details

• Native macOS application using SwiftUI and CoreML.
• Document-based storage (.gaussnb files) for prompts and images.
• Local model management with support for custom hosts.
• Uses Apple Archive (.aar) for model distribution due to GitHub release size limits.

Maintenance & Community

The project is under active development by a single primary developer. Community interaction channels are not explicitly mentioned in the README.

Licensing & Compatibility

The README does not specify a license. Compatibility for commercial use or closed-source linking is not detailed.

Limitations & Caveats

The software is in alpha quality and under development. Intel Macs are untested and may perform poorly. The README does not detail specific feature parity with other Stable Diffusion UIs.
