Phi-4-mini-instruct-int4-ov

• Model creator: Microsoft
• Original model: Phi-4-mini-instruct

Description

This is Phi-4-mini-instruct model converted to the OpenVINO™ IR (Intermediate Representation) format with weights compressed to INT4 by NNCF.

Quantization Parameters

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

• mode: INT4_ASYM
• ratio: 1.0
• group_size: 64
• awq: True
• scale_estimation: True
• dataset: wikitext2

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

Compatibility

The provided OpenVINO™ IR model is compatible with:

• OpenVINO version 2025.1.0 and higher
• Optimum Intel 1.22.0 and higher

Running Model Inference with Optimum Intel

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

pip install optimum[openvino]

1. Run model inference:

from transformers import AutoTokenizer
from optimum.intel.openvino import OVModelForCausalLM
model_id = "OpenVINO/Phi-4-mini-instruct-int4-ov"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = OVModelForCausalLM.from_pretrained(model_id, trust_remote_code=True)

inputs = tokenizer("What is OpenVINO?", return_tensors="pt")
outputs = model.generate(**inputs, max_length=200)
text = tokenizer.batch_decode(outputs)[0]
print(text)

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 openvino openvino-tokenizers openvino-genai
pip install huggingface_hub

1. Download model from HuggingFace Hub

import huggingface_hub as hf_hub
model_id = "OpenVINO/Phi-4-mini-instruct-int4-ov"
model_path = "Phi-4-mini-instruct-int4-ov"
hf_hub.snapshot_download(model_id, local_dir=model_path)

1. Run model inference:

import openvino_genai as ov_genai
device = "CPU"
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
