Ornith-1.5-9B-NPU2

FastFlowLM Q4NX conversion of ornith-ai/Ornith-1.5-9B for AMD XDNA NPU inference.

Ornith-1.5 extends the self-scaffolding framework introduced in Ornith-1.0 into a more complete self-improvement loop:
The model proposes new tasks, generates task-specific scaffolds, and produces solution rollouts for reinforcement learning, continuously creating new learning experiences from which it can improve.

Ornith-1.5 9B is the direct successor of Ornith-1.0 9B, which achieves state-of-the-art performance among open-source models of comparable size across a broad range of agentic coding benchmarks.
It brings improved instruction following & improved thinking/reasoning, among other benefits.

Highly Recommended: Always keep reasoning/thinking enabled.
Ornith thoroughly plans and reasons through code edits before execution, ensuring an efficient and clean output.
Unlike baseline Qwen models, which frequently execute blindly and backtrack after generating broken code.

** Doesn't handle parallel tool calls well **

This repository contains a quantized Q4NX port of the model, compiled for the FastFlowLM (FLM) runtime. It is not a GGUF file.

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
flm-add Atomic-Germ/Ornith-1.5-9B-NPU2 --family qwen3.5 --tag ornith1.5:9b
FLM_CONFIG_PATH="$HOME/.config/flm/model_list.json" FLM_XCLBIN_PATH="$HOME/.config/flm" flm run ornith1.5:9b
