phi-2-int4-ov
Description
This is phi-2 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_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 2024.1.0 and higher
- Optimum Intel 1.16.0 and higher
Running Model Inference
- Install packages required for using Optimum Intel integration with the OpenVINO backend:
pip install optimum[openvino]
- Run model inference:
from transformers import AutoTokenizer
from optimum.intel.openvino import OVModelForCausalLM
model_id = "OpenVINO/phi-2-int4-ov"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = OVModelForCausalLM.from_pretrained(model_id)
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 OpenVINO Large Language Model Inference Guide.
