Optionally, you can install gguf with the extra 'gui' to enable the visual GGUF editor.

pip install gguf[gui]

examples/reader.py — Extracts and displays key-value pairs and tensor details from a GGUF file in a readable format.

gguf/scripts/gguf_dump.py — Dumps a GGUF file's metadata to the console.

gguf/scripts/gguf_set_metadata.py — Allows changing simple metadata values in a GGUF file by key.

gguf/scripts/gguf_convert_endian.py — Allows converting the endianness of GGUF files.

2. Create a tag named gguf-vx.x.x where x.x.x is the semantic version number.

git tag -a gguf-v1.0.0 -m "Version 1.0 release"

3. Push the tags.

git push origin --tags

Manual publishing

3. Upload the generated distribution archives:

python -m twine upload dist/*
