Qwen2.5-VL-7B-Instruct-int8-ov

Qwen2.5-VL-7B-Instruct-int8-ov

• Model creator: Qwen
• Original model: Qwen/Qwen2.5-VL-7B-Instruct

Description

This is Qwen/Qwen2.5-VL-7B-Instruct model converted to the OpenVINO™ IR (Intermediate Representation) format with weights compressed to INT8 by NNCF.

Quantization Parameters

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

• mode: INT8_ASYM

Compatibility

The provided OpenVINO™ IR model is compatible with:

• OpenVINO version 2025.4.0 and higher
• Optimum Intel 1.27.0 and higher

Running Model Inference with OpenVINO GenAI

1. Install packages required for using OpenVINO GenAI.

pip install --pre -U --extra-index-url https://storage.openvinotoolkit.org/simple/wheels/pre-release openvino openvino-tokenizers openvino-genai

pip install huggingface_hub

1. Download model from HuggingFace Hub

import huggingface_hub as hf_hub

model_id = "OpenVINO/Qwen2.5-VL-7B-Instruct-int8-ov"
model_path = "Qwen2.5-VL-7B-Instruct-int8-ov"

hf_hub.snapshot_download(model_id, local_dir=model_path)

1. Run model inference:

import openvino_genai as ov_genai
import requests
from PIL import Image
from io import BytesIO
import numpy as np
import openvino as ov

device = "CPU"
pipe = ov_genai.VLMPipeline(model_path, device)

def load_image(image_file):
    if isinstance(image_file, str) and (image_file.startswith("http") or image_file.startswith("https")):
        response = requests.get(image_file)
        image = Image.open(BytesIO(response.content)).convert("RGB")
    else:
        image = Image.open(image_file).convert("RGB")
    image_data = np.array(image.getdata()).reshape(1, image.size[1], image.size[0], 3).astype(np.uint8)
    return ov.Tensor(image_data)

prompt = "What is unusual in this picture?"

url = "https://github.com/openvinotoolkit/openvino_notebooks/assets/29454499/d5fbbd1a-d484-415c-88cb-9986625b7b11"
image_tensor = load_image(url)

def streamer(subword: str) -> bool:
    print(subword, end="", flush=True)
    return False

pipe.start_chat()
output = pipe.generate(prompt, image=image_tensor, max_new_tokens=100, streamer=streamer)
pipe.finish_chat()
