Add native MTP support for the dense Qwen 3.5 architecture (0.8B, 2B, 4B, 9B, 27B). What works: - MTP graph builder for dense qwen35 (build_mtp_head in qwen35.cpp) - MTP tensor loading and registration for QWEN35 arch - GGUF converter handles MTP tensors (mtp.fc, mtp.layers, mtp.norm, etc.) - Public API: llama_get_mtp_logits(), llama_model_n_mtp_layers() - Server auto-detects MTP from GGUF metadata - Speculative state machine for MTP draft token generation - PR #20075 applied: recurrent state checkpoint/restore for hybrid models - M-RoPE position check relaxed for speculative re-evaluation - Windows os.kill fix for gateway process detection What needs work: - Speculative verify loop conflicts with tool-calling requests (400 error) - The recommended fix: bypass the speculative framework entirely and implement MTP acceptance directly in the server generation loop (no seq_rm/rollback needed since MTP drafts are produced in-graph) - MTP attention skipped (projection + FFN path only) due to inp_out_ids token count mismatch Tested on: RTX 5060 8GB, Windows 11, CUDA 13.2 Model: Qwen3.5-9B with MTP tensors (Q4_K_M quantization) Base: llama.cpp b8388 |

gguf
This is a Python package for writing binary files in the GGUF (GGML Universal File) format.
See convert_hf_to_gguf.py as an example for its usage.
Installation
pip install gguf
Optionally, you can install gguf with the extra 'gui' to enable the visual GGUF editor.
pip install gguf[gui]
API Examples/Simple Tools
examples/writer.py — Generates example.gguf in the current directory to demonstrate generating a GGUF file. Note that this file cannot be used as a model.
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.
gguf/scripts/gguf_new_metadata.py — Copies a GGUF file with added/modified/removed metadata values.
gguf/scripts/gguf_editor_gui.py — Allows for viewing, editing, adding, or removing metadata values within a GGUF file as well as viewing its tensors with a Qt interface.
Development
Maintainers who participate in development of this package are advised to install it in editable mode:
cd /path/to/llama.cpp/gguf-py
pip install --editable .
Note: This may require to upgrade your Pip installation, with a message saying that editable installation currently requires setup.py.
In this case, upgrade Pip to the latest:
pip install --upgrade pip
Automatic publishing with CI
There's a GitHub workflow to make a release automatically upon creation of tags in a specified format.
- Bump the version in
pyproject.toml. - Create a tag named
gguf-vx.x.xwherex.x.xis the semantic version number.
git tag -a gguf-v1.0.0 -m "Version 1.0 release"
- Push the tags.
git push origin --tags
Manual publishing
If you want to publish the package manually for any reason, you need to have twine and build installed:
pip install build twine
Then, follow these steps to release a new version:
- Bump the version in
pyproject.toml. - Build the package:
python -m build
- Upload the generated distribution archives:
python -m twine upload dist/*
Run Unit Tests
From root of this repository you can run this command to run all the unit tests
python -m unittest discover ./gguf-py -v
TODO
- Include conversion scripts as command line entry points in this package.
