Phi-3.5-vision-instruct-int8-ov

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

Description

This is microsoft/Phi-3.5-vision-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 2025.0.0 and higher
• Optimum Intel 1.21.0 and higher

Running Model Inference with Optimum Intel

1. Install packages required for using Optimum Intel 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
