Phi-3.5-vision-instruct-nf4-ov

• Model creator: microsoft
• Original model: Phi-3.5-vision-instruct

Description

This is Phi-3.5-vision-instruct model converted to the OpenVINO™ IR (Intermediate Representation) format with weights compressed to NF4 by NNCF.

The model is optimized for inference on NPU using these instructions.

Quantization Parameters

Weight compression was performed using nncf.compress_weights with the following parameters:

• mode: NF4
• group_size: -1
• ratio: 1.0

For more information on quantization, check the OpenVINO model optimization guide.

Compatibility

The provided OpenVINO™ IR model is compatible with:

• OpenVINO version 2026.4.0 and higher
• Intel® NPU Driver - Windows* 32.0.100.4023 for Intel® Core™ Ultra processors and higher

NPU support is compatible with Intel® Core™ Ultra 200V Series processors and Intel® Core™ Ultra Series 3 processors.

Running Model Inference with OpenVINO GenAI

1. Install packages required for using OpenVINO GenAI.

pip install openvino-genai huggingface_hub pillow

2. Download model from HuggingFace Hub

import huggingface_hub as hf_hub

model_id = "OpenVINO/Phi-3.5-vision-instruct-nf4-ov"
model_path = "Phi-3.5-vision-instruct-nf4-ov"

hf_hub.snapshot_download(model_id, local_dir=model_path)

3. Run model inference:

import numpy as np
import openvino as ov
import openvino_genai as ov_genai
from PIL import Image

device = "NPU"
pipe = ov_genai.VLMPipeline(model_path, device)
image = ov.Tensor(np.array(Image.open("image.jpg").convert("RGB")))
result = pipe.generate("What is in this image?", image=image, max_new_tokens=100)
print(result.texts[0])

With device="NPU", OpenVINO GenAI runs the language model on the NPU.

More GenAI usage examples can be found in OpenVINO GenAI library docs and samples.
