Gemma 4 31B QAT MTP drafter

Multi-Token Prediction (MTP) drafter for unsloth/gemma-4-31B-it-qat-GGUF. It runs as a speculative draft model that shares the target's KV cache and speeds up text generation. The drafter is the Gemma 4 31B QAT assistant and pairs with the QAT model unchanged.

Verified on a single B200 against the gemma-4-31B-it-qat-UD-Q4_K_XL.gguf target with -hf auto-discovery: draft acceptance 0.79.

MTP was merged into llama.cpp on 2026-06-07 (PR ggml-org/llama.cpp#23398). You need a llama.cpp build from after that date. Older builds cannot load these (arch gemma4-assistant).

Files

The recommended drafter is a smart Q4_0: the native 4-bit QAT drafter (about 97% of its weights are byte-exact on the int4 grid), near-lossless versus higher precision while roughly half the size. It sits at the repo root as mtp-gemma-4-31B-it.gguf so -hf finds it automatically, and the same file plus higher-precision drafters are in MTP/:

mtp-gemma-4-31B-it.gguf (repo root, smart Q4_0, recommended; used by -hf)
MTP/mtp-gemma-4-31B-it-Q4_0.gguf (same smart Q4_0)
MTP/mtp-gemma-4-31B-it-Q8_0.gguf
MTP/mtp-gemma-4-31B-it-BF16.gguf
MTP/mtp-gemma-4-31B-it-F16.gguf

Build llama.cpp

git clone https://github.com/ggml-org/llama.cpp
cd llama.cpp

# CUDA build. Set the arch for your GPU: 89 (RTX 4090), 90 (H100), 100 (B200).
cmake -B build -DGGML_CUDA=ON -DCMAKE_CUDA_ARCHITECTURES=90
cmake --build build --config Release -j --target llama-server

Run, the easy way

A recent llama.cpp finds the drafter automatically from the root mtp- file, so -hf is all you need. No --model-draft.

./build/bin/llama-server \
  -hf unsloth/gemma-4-31B-it-qat-GGUF:UD-Q4_K_XL \
  --spec-type draft-mtp --spec-draft-n-max 4 \
  -ngl 999 -fa on

If your build is too old to auto-discover the sibling, use the explicit form below.

Run with an explicit drafter

Use this to choose a precision or point at a local file.

hf download unsloth/gemma-4-31B-it-qat-GGUF gemma-4-31B-it-qat-UD-Q4_K_XL.gguf --local-dir .
hf download unsloth/gemma-4-31B-it-qat-GGUF MTP/mtp-gemma-4-31B-it-Q8_0.gguf --local-dir .

./build/bin/llama-server \
  -m gemma-4-31B-it-qat-UD-Q4_K_XL.gguf \
  --model-draft MTP/mtp-gemma-4-31B-it-Q8_0.gguf \
  --spec-type draft-mtp --spec-draft-n-max 4 \
  -ngl 999 -fa on

Multi GPU: add --spec-draft-device CUDA0 -sm layer. The drafter pairs with any quant of the 31B QAT model. Quantized KV cache works.
