Step 3.7 Flash MTP Draft GGUFs

These are companion MTP draft GGUFs for speculative decoding. They are not standalone chat models.

Use them with the full model repo:

notSnix/Step-3.7-Flash-Q4_K_M-GGUF

The draft GGUF is passed with --model-draft; the full model is passed with --model.

Runtime

Current llama.cpp main supports Step MTP-tail draft loading natively. This was smoke-tested with clean llama.cpp commit d545a2a993849fcf3b752d85ae256fc9d6a9de79.

git clone https://github.com/ggml-org/llama.cpp
cd llama.cpp
cmake -B build-cuda -DGGML_CUDA=ON
cmake --build build-cuda --config Release -j

Which Draft Should I Use?

Use Step-3.7-Flash-MTP-Q8_0.gguf first. It was the best local default in testing.

Use Step-3.7-Flash-MTP-Q6_K.gguf if you want a smaller draft file while staying above Q4.

Use Step-3.7-Flash-MTP-Q4_K_M.gguf if you want the smaller draft file.

Use Step-3.7-Flash-MTP-BF16.gguf for experimentation.

Notes

These files intentionally keep the upstream Step MTP tail-layer numbering (blk.45, blk.46, blk.47).
They are companion speculative-decoding draft GGUFs, not full-model quants.
The full Q4_K_M model is hosted separately so Hugging Face's GGUF widget does not display draft files as tiny full-model quantizations.
This is a community GGUF conversion of the upstream Apache-2.0 model, not an official StepFun release.
