IF YOU USE COMMUNITY QWEN MODELS DO NOT UPGRADE TO FLM v1.0.2+

Grug-35B-A3B - Q4NX for FastFlowLM (AMD Ryzen AI XDNA2)

Grug 35B A3B is a compact-reasoning fine-tune of Qwen/Qwen3.6-35B-A3B. It keeps the Qwen MoE/A3B architecture: 35B total parameters with roughly 3B activated per token, 40 text layers, 256 experts, and 8 routed experts per token plus the shared expert path. Converted to Q4NX for FastFlowLM. This variant ships vision Q4NX weights alongside the text weights.

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
~51 GB of unified system memory (Q4NX weights + activations + KV cache)

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. It never modifies the system FastFlowLM install.

pip install flm-add or uv tool install flm-add

bash

uv tool install flm-add
flm-add Atomic-Germ/Grug-35B-A3B-NPU2 --tag grug-moe:35b-a3b --family qwen3.6-moe
FLM_CONFIG_PATH="$HOME/.config/flm/model_list.json" FLM_XCLBIN_PATH="$HOME/.config/flm" flm run grub-moe:35b-a3b

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 qwen3.6-moe:35b-a3b model (Qwen3.6-35B-A3B-NPU2), because this model shares the same engine family (qwen3.6-moe) and architecture.
