Phi-3.5-mini-instruct-int4-gq-ov

Model creator: microsoft
Original model: Phi-3.5-mini-instruct

Description

This is Phi-3.5-mini-instruct model converted to the OpenVINO™ IR (Intermediate Representation) format with weights compressed to INT4 by NNCF.

[!NOTE]
The model is optimized for inference on NPU using these instructions.

Quantization Parameters

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

mode: INT4_SYM
ratio: 1.0
group_size: 128

For more information on quantization, check the OpenVINO model optimization guide.

Compatibility

The provided OpenVINO™ IR model is compatible with:

OpenVINO version 2026.2.0 and higher
Intel® NPU Driver - Windows* 32.0.100.4023 for Intel® Core™ Ultra processors and higher

[!NOTE] NPU support is compatible with Intel® Core™ Ultra 200V Series processors and Intel® Core™ Ultra Series 3 processors.

Running Model Inference with OpenVINO GenAI

Install packages required for using OpenVINO GenAI.

pip install openvino-genai huggingface_hub

Download model from HuggingFace Hub

python

import huggingface_hub as hf_hub

model_id = "OpenVINO/Phi-3.5-mini-instruct-int4-gq-ov"
model_path = "Phi-3.5-mini-instruct-int4-gq-ov"

hf_hub.snapshot_download(model_id, local_dir=model_path)

Run model inference:

python

import openvino_genai as ov_genai

device = "NPU"
pipe = ov_genai.LLMPipeline(model_path, device)
print(pipe.generate("What is OpenVINO?", max_length=200))

More GenAI usage examples can be found in OpenVINO GenAI library docs and samples
