Why AutoGGUF?

• Fast: Saves time on manual configuration
• Simple: Clean UI, no terminal needed
• Powerful: Handles models up to infinite size, only limited by your RAM
• Resource-aware: Optimized memory management and efficient UI library

Quick Start

Cross-platform

1. git clone https://github.com/leafspark/AutoGGUF
2. cd AutoGGUF
3. Install dependencies:

   pip install -r requirements.txt
   

4. Run the application:

   python src/main.py
   

   or use the run.bat script.

macOS and Ubuntu builds are provided with GitHub Actions, you may download the binaries in the releases section.

Windows (for the impatient)

Standard builds:

1. Download the latest release
2. Extract all files to a folder
3. Run AutoGGUF-x64.exe
4. Any necessary folders will be automatically created

Setup builds:

1. Download setup variant of latest release
2. Extract all files to a folder
3. Run the setup program
4. The .GGUF extension will be registered with the program automatically
5. Run the program from the Start Menu or desktop shortcuts

After launching the program, you may access its local server at port 7001 (set AUTOGGUF_SERVER to "enabled" first)

Verifying Releases

Linux/macOS:

gpg --import AutoGGUF-v1.5.0-prerel.asc
gpg --verify AutoGGUF-v1.9.1-Windows-avx2.zip.sig AutoGGUF-v1.9.1-Windows-avx2.zip
sha256sum -c AutoGGUF-v1.9.1.sha256

Windows (PowerShell):

# Import the public key
gpg --import AutoGGUF-v1.5.0-prerel.asc

# Verify the signature
gpg --verify AutoGGUF-v1.9.1-Windows-avx2.zip.sig AutoGGUF-v1.9.1-Windows-avx2.zip

# Check SHA256
$fileHash = (Get-FileHash -Algorithm SHA256 AutoGGUF-v1.9.1-Windows-avx2.zip).Hash.ToLower()
$storedHash = (Get-Content AutoGGUF-v1.9.1.sha256 | Select-String AutoGGUF-v1.9.1-Windows-avx2.zip).Line.Split()[0]
if ($fileHash -eq $storedHash) { "SHA256 Match" } else { "SHA256 Mismatch" }

Release keys are identical to ones used for commiting.

Building

Cross-platform

pip install -U pyinstaller
./build.sh RELEASE | DEV
cd build/<type>/dist/
./AutoGGUF

Windows

pip install -U pyinstaller
build RELEASE | DEV

Find the executable in build/<type>/dist/AutoGGUF-x64.exe.

You can also use Nuitka, which may result in a slower build but a faster output executable:

build_optimized RELEASE | DEV

Localizations

View the list of supported languages at AutoGGUF/wiki/Installation#configuration (LLM translated, except for English).

More languages will be updated as soon as possible!

To use a specific language, set the AUTOGGUF_LANGUAGE environment variable to one of the listed language codes (note: some languages may not be fully supported yet, those will fall back to English).

Issues

• Some inconsistent logging and signal handling
• Missing or duplicated translations
• Buggy/incomplete API interfaces

Planned Features

• Time estimation for quantization
• Quantization file size estimate
• Perplexity testing
• bitsandbytes support

Project Status

AutoGGUF has now entered maintenance mode. It's considered stable and feature-complete for most use cases, so I'm not actively developing new features, but I’ll continue to publish occasional builds, update dependencies regularly, and fix critical bugs as needed. If you encounter issues or have suggestions, feel free to open an issue.

Support

• SSL module cannot be found error: Install OpenSSL or run from source using python src/main.py with the run.bat script (pip install requests)
• Check out the Wiki for advanced usage and configuration
