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

Ornith-1.0-35B - Q4NX for FastFlowLM (AMD Ryzen AI XDNA2)

Ornith-1.0-35B is converted to Q4NX for hardware-accelerated inference with FastFlowLM on AMD Ryzen AI NPUs.

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 >= 0.9.46 (flm CLI)
• AMD Ryzen AI processor with XDNA2 (NPU2) - Strix Point / Ryzen AI 300 series or later
• Linux with the XRT NPU stack installed
• ~47 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

uv tool install flm-add
unset FLM_CONFIG_PATH FLM_XCLBIN_PATH && flm-add Atomic-Germ/Ornith-1.0-35B-A3B-NPU2 --tag ornith1.0-moe:35b-a3b --family qwen3.6-moe
FLM_CONFIG_PATH="$HOME/.config/flm/model_list.json" FLM_XCLBIN_PATH="$HOME/.config/flm" flm run ornith1.0-moe:35b-a3b

Kernels

FastFlowLM's NPU kernels (xclbins) are closed source and are not shipped in this repository. This model uses the qwen3.6-moe engine family and is shape-identical to the official qwen3.6-moe:35b-a3b model (Qwen3.6-Moe-35BA3B-NPU2). Point the runtime's xclbin path at the matching xclbins directory (or ship your own) before running.
