Introduction of NuExtract3-4B-NPU2

Model Details of NuExtract3-4B-NPU2

NuExtract3-4B - Q4NX for FastFlowLM (AMD Ryzen AI XDNA2)

A text-extraction Qwen3.5-4B fine-tune, converted to Q4NX for FastFlowLM.

What is Q4NX?

Q4NX is FastFlowLM's native packed-quantization format - a rearranged Q4_1 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 ( flm CLI)
  • 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 uses flm-add.py , a small installer that copies the model into the FastFlowLM user directory and registers the tag. It never modifies the system FastFlowLM install.

Run python3 ./flm-add.py --help for all options. Without a clone, the same command works against the repo id directly:

python3 ./flm-add.py Atomic-Germ/NuExtract3-4B-NPU2 --tag nuextract3:4b --family qwen3.5
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 qwen3.5:4b model ( Qwen3.5-4B-NPU2 ), because this model shares the same engine family ( qwen3.5 ) and architecture.
