This model is a quantized version of microsoft/Phi-3.5-mini-instruct and is converted to the OpenVINO format. This model was obtained via the nncf-quantization space with optimum-intel. First make sure you have optimum-intel installed:

pip install optimum[openvino]

To load your model you can do as follows:

from optimum.intel import OVModelForCausalLM
model_id = "AlexKoff88/Phi-3.5-mini-instruct-openvino-8bit"
model = OVModelForCausalLM.from_pretrained(model_id)
