Qwen3.8-27B-int4-ov

Model creator: Qwen
Original model: Qwen/Qwen3.8-27B

EXPERIMENTAL MODEL This model has not been fully validated with OpenVINO and currently requires development versions of Optimum Intel and OpenVINO. It may be fully supported and validated in future releases.

Description

This is the Qwen3.8-27B model converted to the OpenVINO™ IR (Intermediate Representation) format with weights compressed to INT4 by NNCF.

Qwen3.8-27B is a native vision-language model with image and video understanding, flexible thinking control, and support for complex multi-step tasks.

Quantization Parameters

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

mode: INT4_ASYM
group_size: 128
ratio: 1.0

For more information about quantization, see the OpenVINO model optimization guide.

Compatibility

The provided OpenVINO IR model is compatible with:

OpenVINO 2026.4.0 (nightly) and higher
OpenVINO GenAI nightly builds from August 14, 2026 and later
The latest Optimum Intel development version
Transformers 5.2

Running Model Inference with Optimum Intel

Install the packages required to use Optimum Intel with the OpenVINO backend:

bash

pip install -U "git+https://github.com/huggingface/optimum-intel.git" torchvision Pillow --extra-index-url https://download.pytorch.org/whl/cpu
pip install --pre -U openvino --extra-index-url https://storage.openvinotoolkit.org/simple/wheels/nightly
pip install -U "transformers==5.2"

Run model inference:

python

import requests
from PIL import Image
from transformers import AutoProcessor
from optimum.intel.openvino import OVModelForVisualCausalLM

model_id = "OpenVINO/Qwen3.8-27B-int4-ov"
processor = AutoProcessor.from_pretrained(model_id)
model = OVModelForVisualCausalLM.from_pretrained(model_id)

url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/ai2d-demo.jpg"
image = Image.open(requests.get(url, stream=True).raw)

messages = [
    {
        "role": "user",
        "content": [
            {"type": "image"},
            {"type": "text", "text": "Describe this image."},
        ],
    }
]

text = processor.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = processor(text=[text], images=[image], return_tensors="pt")

outputs = model.generate(**inputs, max_new_tokens=200)
print(processor.batch_decode(outputs[:, inputs.input_ids.shape[1] :], skip_special_tokens=True)[0])

For more examples and possible optimizations, refer to Inference with Optimum Intel.

Running Model Inference with OpenVINO GenAI

Install the packages required to use OpenVINO GenAI:

bash

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

Download the model from Hugging Face Hub:

python

import huggingface_hub as hf_hub

model_id = "OpenVINO/Qwen3.8-27B-int4-ov"
model_path = "Qwen3.8-27B-int4-ov"

hf_hub.snapshot_download(model_id, local_dir=model_path)

Run model inference:

python

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

device = "CPU"
model_path = "Qwen3.8-27B-int4-ov"
pipe = ov_genai.VLMPipeline(model_path, device)

url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/ai2d-demo.jpg"
image = Image.open(requests.get(url, stream=True).raw).convert("RGB")
image_tensor = ov.Tensor(np.array(image)[None])

print(pipe.generate("Describe this image.", image=image_tensor, max_new_tokens=200))

Running Model with OpenAI client and OpenVINO Model Server

1a. Deploy model on Windows using binary package:

curl -o ovms.zip https://storage.openvinotoolkit.org/repositories/openvino_model_server/packages/weekly/latest/ovms_windows_2026.4.0_python_on.zip
tar -xzf ovms.zip
ovms\setupvars.bat
set OVMS_MEDIA_URL_ALLOW_REDIRECTS=1
ovms.exe --rest_port 8000 --source_model OpenVINO/Qwen3.8-27B-int4-ov --model_repository_path C:\models --allowed_media_domains all

1b. Deploy model in a Docker container:

export GPU_ARGS=$(if ls /dev/dri/render* >/dev/null 2>&1; then echo "--device /dev/dri --group-add $(stat -c '%g' /dev/dri/render* | head -n1)"; fi)
docker run -d ${GPU_ARGS} -e "OVMS_MEDIA_URL_ALLOW_REDIRECTS=1" -u $(id -u):$(id -g) --rm -p 8000:8000 -v ${HOME}/models:/models:rw openvino/model_server:weekly \
--rest_port 8000 --model_repository_path /models --source_model OpenVINO/Qwen3.8-27B-int4-ov --allowed_media_domains all

Install the client library:

pip install openai

Run the client:

from openai import OpenAI

client = OpenAI(
  base_url="http://localhost:8000/v1",
  api_key="unused"
)

image_url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/ai2d-demo.jpg"

stream = client.chat.completions.create(
    model="OpenVINO/Qwen3.8-27B-int4-ov",
    messages=[
    {
        "role": "user",
        "content": [
            {"type": "image_url", "image_url": {"url": image_url}},
            {"type": "text", "text": "Describe this image."},
        ],
    }
    ],
    stream=True,
    extra_body={"chat_template_kwargs": {"reasoning_effort": "medium"}},
    tools=[],

for chunk in stream:
    if not chunk.choices:
        continue
    delta = chunk.choices[0].delta

    content = getattr(delta, "content", None)
    reasoning = getattr(delta, "reasoning_content", None)

    if content:
        if not printing_content_started:
            printing_content_started = True
            print("\ncontent:\n", end="", flush=True)
        print(content, end="", flush=True)
    if reasoning:
        if not printing_reasoning_started:
