BGE-M3 OpenVINO INT4 ASYM g64

Locally compressed derivative of BAAI/bge-m3 for dense embedding inference with OpenVINO. NNCF settings: INT4_ASYM, group size 64, ratio 1.0, scale estimation disabled. NNCF retained protected backup layers as INT8 ASYM.

LoCoMo (English, dense retrieval) macro average: nDCG@10 44.644%, Recall@10 59.425%, MRR@10 43.496%, Hit@10 68.601%. Tested with OpenVINO 2026.3 on Intel Arc 140V GPU. Embedding dimension is 1024 and maximum sequence length is 8192.

Usage

python

import numpy as np
import openvino as ov
from huggingface_hub import snapshot_download
from transformers import AutoTokenizer

repo_id = "YOUR_USERNAME/bge-m3-int4-asym-g64-openvino"
path = snapshot_download(repo_id)
tokenizer = AutoTokenizer.from_pretrained(path)
compiled = ov.Core().compile_model(
    f"{path}/openvino/openvino_model.xml",
    "GPU",  # use "CPU" when needed
)

tokens = tokenizer(
    ["xin chào, đây là phép thử"],
    padding=True,
    truncation=True,
    max_length=8192,
    return_tensors="np",
)
embedding = np.asarray(
    compiled({
        "input_ids": tokens["input_ids"],
        "attention_mask": tokens["attention_mask"],
    })[compiled.output("sentence_embedding")],
    dtype=np.float32,
)
embedding /= np.maximum(np.linalg.norm(embedding, axis=1, keepdims=True), 1e-12)
print(embedding.shape)  # (1, 1024)
