gte-multilingual-reranker-base

The gte-multilingual-reranker-base model is the first reranker model in the GTE family of models, featuring several key attributes:

High Performance: Achieves state-of-the-art (SOTA) results in multilingual retrieval tasks and multi-task representation model evaluations when compared to reranker models of similar size.
Training Architecture: Trained using an encoder-only transformers architecture, resulting in a smaller model size. Unlike previous models based on decode-only LLM architecture (e.g., gte-qwen2-1.5b-instruct), this model has lower hardware requirements for inference, offering a 10x increase in inference speed.
Long Context: Supports text lengths up to 8192 tokens.
Multilingual Capability: Supports over 70 languages.

Model Information

Model Size: 306M
Max Input Tokens: 8192

Usage

It is recommended to install xformers and enable unpadding for acceleration, refer to enable-unpadding-and-xformers.
How to use it offline: new-impl/discussions/2

Using Huggingface transformers (transformers>=4.36.0)

import torch
from transformers import AutoModelForSequenceClassification, AutoTokenizer

model_name_or_path = "Alibaba-NLP/gte-multilingual-reranker-base"

tokenizer = AutoTokenizer.from_pretrained(model_name_or_path)
model = AutoModelForSequenceClassification.from_pretrained(
    model_name_or_path, trust_remote_code=True,
    torch_dtype=torch.float16
)
model.eval()

pairs = [["中国的首都在哪儿","北京"], ["what is the capital of China?", "北京"], ["how to implement quick sort in python?","Introduction of quick sort"]]
with torch.no_grad():
    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)

# tensor([1.2315, 0.5923, 0.3041])

Usage with infinity:

Infinity, a MIT Licensed Inference RestAPI Server.

docker run --gpus all -v $PWD/data:/app/.cache -p "7997":"7997" \
michaelf34/infinity:0.0.68 \
v2 --model-id Alibaba-NLP/gte-multilingual-reranker-base --revision "main" --dtype bfloat16 --batch-size 32 --device cuda --engine torch --port 7997

Usage with Text Embeddings Inference (TEI):

CPU:

bash

docker run --platform linux/amd64 \
  -p 8080:80 \
  -v $PWD/data:/data \
  --pull always \
  ghcr.io/huggingface/text-embeddings-inference:cpu-1.7 \
  --model-id Alibaba-NLP/gte-multilingual-reranker-base

GPU:

docker run --gpus all \
  -p 8080:80 \
  -v $PWD/data:/data \
  --pull always \
  ghcr.io/huggingface/text-embeddings-inference:1.7 \
  --model-id Alibaba-NLP/gte-multilingual-reranker-base

Then you can send requests to the deployed API via the /rerank route (see the Text Embeddings Inference OpenAPI Specification for more details):

bash

curl https://0.0.0.0:8080/rerank \
  -H "Content-Type: application/json" \
  -d '{
    "query": "中国的首都在哪儿",
    "raw_scores": false,
    "return_text": false,
    "texts": [ "北京" ],
    "truncate": true,
    "truncation_direction": "right"
  }'

Evaluation

Results of reranking based on multiple text retreival datasets

More detailed experimental results can be found in the paper.

Cloud API Services

In addition to the open-source GTE series models, GTE series models are also available as commercial API services on Alibaba Cloud.

Embedding Models: Three versions of the text embedding models are available: text-embedding-v1/v2/v3, with v3 being the latest API service.
ReRank Models: The gte-rerank model service is available.

Note that the models behind the commercial APIs are not entirely identical to the open-source models.
