GPT-OSS-GPT5.2-Distill-NPU2 - Q4NX for FastFlowLM (AMD Ryzen AI XDNA2)
A code-focused GPT-OSS-20B fine-tune, converted to Q4NX for FastFlowLM.
What is Q4NX?
Q4NX is FastFlowLM's native packed-quantization format - in the case of GPT-OSS a rearranged Q4_1-Q4NX layout tuned for the NPU matrix engine's tile sizes and memory access patterns. It is not a GGUF file and it does not run on llama.cpp or Ollama; it is meant exclusively for the FastFlowLM engine on AMD Ryzen AI NPUs.
Requirements
- FastFlowLM >= 0.9.45 (
flmCLI) - AMD Ryzen AI processor with XDNA2 (NPU2) - Strix Point / Ryzen AI 300 series or later
- Linux with the XRT NPU stack installed
- ~16 GB of unified system memory (Q4NX weights + activations + KV cache)
Files
| File | Purpose |
|---|---|
| model.q4nx | Quantized Q4NX weights |
| config.json | FastFlowLM model configuration |
| tokenizer.json | Tokenizer |
| tokenizer_config.json | Special tokens and chat template |
| chat_template.jinja | Chat template (optional) |
| flm-add.py | Installer script - registers this model with FastFlowLM |
Install and run
This repository works with flm-add, a small installer that copies the model
into the FastFlowLM user directory and registers the tag minicpm4.6:0.8b. It never
modifies the system FastFlowLM install.
pip install flm-add or uv tool install flm-add
uv tool install flm-add
flm-add Atomic-Germ/GPT-OSS-GPT5.2-Distill-NPU2 --tag gpt5.2-distill:20b --family gpt-oss
FLM_CONFIG_PATH="$HOME/.config/flm/model_list.json" FLM_XCLBIN_PATH="$HOME/.config/flm" flm run gpt5.2-distill:20b
Kernels
FastFlowLM's NPU kernels (xclbins) are closed source and are not shipped in
this repository. flm-add.py links the kernels of the official gpt-oss:20b
model (GPT-OSS-20B-NPU2), because this model shares the same engine family
(gpt-oss) and architecture.
