# pixtral-12b-int4-ov
* Model creator: [mistral-community](https://huggingface.co/mistral-community)
* Original model: [mistral-community/pixtral-12b](https://huggingface.co/mistral-community/pixtral-12b)
## Description
This is [mistral-community/pixtral-12b](https://huggingface.co/mistral-community/pixtral-12b) model converted to the [OpenVINO™ IR](https://docs.openvino.ai/2025/documentation/openvino-ir-format.html) (Intermediate Representation) format with weights compressed to INT4 by [NNCF](https://github.com/openvinotoolkit/nncf).
## Quantization Parameters
Weight compression was performed using `nncf.compress_weights` with the following parameters:
* mode: **INT4_ASYM**
## Compatibility
The provided OpenVINO™ IR model is compatible with:
* OpenVINO version 2025.2.0 and higher
* Optimum Intel 1.26.0 and higher
## Running Model Inference with [Optimum Intel](https://huggingface.co/docs/optimum/intel/index)
1. Install packages required for using [Optimum Intel](https://huggingface.co/docs/optimum/intel/index) integration with the OpenVINO backend:
```
pip install --pre -U --extra-index-url https://storage.openvinotoolkit.org/simple/wheels/pre-release openvino_tokenizers openvino
pip install git+https://github.com/huggingface/optimum-intel.git
```
2. Run model inference
```
from PIL import Image
import requests
from optimum.intel.openvino import OVModelForVisualCausalLM
from transformers import AutoProcessor, TextStreamer
model_id = "OpenVINO/pixtral-12b-int4-ov"
processor = AutoProcessor.from_pretrained(model_id)
ov_model = OVModelForVisualCausalLM.from_pretrained(model_id, trust_remote_code=True)
question = "What is unusual in this picture?"
messages = [
{"role": "user", "content": [{"type": "text", "content": question}, {"type": "image"}]},
]
text = processor.apply_chat_template(messages, add_generation_prompt=True, tokenize=False)
url = "https://github.com/openvinotoolkit/openvino_notebooks/assets/29454499/d5fbbd1a-d484-415c-88cb-9986625b7b11"
raw_image = Image.open(requests.get(url, stream=True).raw)
inputs = processor(text=text, images=[raw_image], return_tensors="pt")
streamer = TextStreamer(processor.tokenizer, skip_prompt=True, skip_special_tokens=True)
output = ov_model.generate(**inputs, do_sample=False, max_new_tokens=100, temperature=None, top_p=None, streamer=streamer)
```
