Qwen3.5-0.8B-fp16-ov

• Model creator: Qwen
• Original model: Qwen3.5-0.8B

Description

This is Qwen3.5-0.8B model converted to the OpenVINO™ IR (Intermediate Representation) format.

The model includes openvino_mtp_model.xml for built-in Multi-Token Prediction (MTP) speculative decoding.

Compatibility

The provided OpenVINO™ IR model is compatible with:

• OpenVINO 2026.4.0 and higher
• OpenVINO GenAI 2026.4.0.0 and higher
• Optimum Intel 1.27.0 and higher

Running Model Inference with Optimum Intel

1. Install packages required for using Optimum Intel integration with the OpenVINO backend:

pip install -U "git+https://github.com/huggingface/optimum-intel.git" torchvision Pillow --extra-index-url https://download.pytorch.org/whl/cpu
pip install -U "openvino==2026.4.0"
pip install -U "transformers==5.2.0"

2. Run model inference:

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

model_id = "OpenVINO/Qwen3.5-0.8B-fp16-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 the Inference with Optimum Intel.

Running Model Inference with OpenVINO GenAI

1. Install packages required for using OpenVINO GenAI.

pip install -U huggingface_hub "Pillow"
pip install -U "openvino==2026.4.0" "openvino-tokenizers==2026.4.0.0" "openvino-genai==2026.4.0.0"

2. Download model from HuggingFace Hub

import huggingface_hub as hf_hub

model_id = "OpenVINO/Qwen3.5-0.8B-fp16-ov"
model_path = "Qwen3.5-0.8B-fp16-ov"

hf_hub.snapshot_download(model_id, local_dir=model_path)

3. Run model inference with MTP:

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

device = "CPU"
scheduler_config = ov_genai.SchedulerConfig()
scheduler_config.enable_prefix_caching = False
draft = ov_genai.draft_model(model_path, device)
pipe = ov_genai.VLMPipeline(
    model_path,
    device,
    draft_model=draft,
    scheduler_config=scheduler_config,
)

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])

generation_config = ov_genai.GenerationConfig()
generation_config.max_new_tokens = 200
generation_config.do_sample = False
generation_config.num_return_sequences = 1
generation_config.num_assistant_tokens = 2

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

OpenVINO GenAI currently supports this MTP path with greedy decoding and prefix caching disabled, as demonstrated in the Qwen3.8 MTP notebook.
