How to use OpenFlowLM/Medgemma-4B-NPU2 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("image-text-to-text", model="OpenFlowLM/Medgemma-4B-NPU2")
messages = [

            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForMultimodalLM

tokenizer = AutoTokenizer.from_pretrained("OpenFlowLM/Medgemma-4B-NPU2")
model = AutoModelForMultimodalLM.from_pretrained("OpenFlowLM/Medgemma-4B-NPU2", device_map="auto")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Medgemma-4B-NPU2

OpenFlowLM Q4NX conversion of Atomic-Germ/Medgemma-4B-NPU2 for AMD XDNA NPU inference.

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

Item	Value
Source model	`Atomic-Germ/Medgemma-4B-NPU2`
Source GGUF	`medgemma-4b-it.i1-Q4_1.gguf`
Weights	`model.q4nx` (3.51 GB)
Modality	language
OFLM version	`0.1.0`
Converted	2026-10-01

Reproduce this conversion

This container was produced by exactly this command, so a fine-tune of the same base can be packed the same way:

oflm pack -i /home/atomic-germ/.cache/huggingface/hub/models--mradermacher--medgemma-4b-it-i1-GGUF/snapshots/e72473b68139c8f77427dd21270eff3b2b80c1f9/medgemma-4b-it.i1-Q4_1.gguf -o /home/atomic-germ/Projects/OpenFlowLM-Next/Medgemma-4B-NPU2 -s Atomic-Germ/Medgemma-4B-NPU2

Install and run

This repository works with oflm-add, a small installer that copies the model into the OpenFlowLM user directory and registers the tag. It never modifies the system OpenFlowLM install.

pip install oflm-add or uv tool install oflm-add

uv tool install oflm-add
oflm-add Atomic-Germ/Medgemma-4B-NPU2 --family qwen3.5 --xclbin-from Medgemma-4B-NPU2
OFLM_CONFIG_PATH="$HOME/.config/oflm/model_list.json" OFLM_XCLBIN_PATH="$HOME/.config/oflm" oflm run Medgemma-4B-NPU2
