Disclaimer: This model is provided for evaluation purposes only. Performance, accuracy, and stability may vary. Use at your own discretion.

• Model creator: BAAI
• Original model: bge-reranker-base

Description

This is bge-reranker-base model converted to the OpenVINO™ IR (Intermediate Representation) format with weights compressed to FP16.

Compatibility

The provided OpenVINO™ IR model is compatible with:

• OpenVINO version 2025.1.0 and higher
• Optimum Intel 1.24.0 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]

2. Run model inference:

from transformers import AutoTokenizer
from optimum.intel import OVModelForSequenceClassification


tokenizer = AutoTokenizer.from_pretrained('OpenVINO/bge-reranker-base-fp16-ov')
model = OVModelForSequenceClassification.from_pretrained('OpenVINO/bge-reranker-base-fp16-ov')

pairs = [['what is panda?', 'hi'], ['what is panda?', 'The giant panda (Ailuropoda melanoleuca), sometimes called a panda bear or simply panda, is a bear species endemic to China.']]

inputs = tokenizer(pairs, padding=True, truncation=True, return_tensors='pt', max_length=512)
scores = model(**inputs, return_dict=True).logits.view(-1, ).float()
print(scores)

For more examples and possible optimizations, refer to the Inference with Optimum Intel.

You can find more detailed usage examples in OpenVINO Notebooks:

• RAG text generation
