    [1\]: If you need to search the relevant passages to a query, we suggest to add the instruction to the query; in other cases, no instruction is needed, just use the original query directly. In all cases, no instruction needs to be added to passages.

    [2\]: Different from embedding model, reranker uses question and document as input and directly output similarity instead of embedding. To balance the accuracy and time cost, cross-encoder is widely used to re-rank top-k documents retrieved by other simple models. For examples, use bge embedding model to retrieve top 100 relevant documents, and then use bge reranker to re-rank the top 100 document to get the final top-3 results.

    All models have been uploaded to Huggingface Hub, and you can see them at https://huggingface.co/BAAI. If you cannot open the Huggingface Hub, you also can download the models at https://model.baai.ac.cn/models .

    Frequently asked questions



    1. How to fine-tune bge embedding model?

    How to fine-tune bge embedding model? -->

    Following this example to prepare data and fine-tune your model. Some suggestions:
  • Mine hard negatives following this example, which can improve the retrieval performance.
  • If you pre-train bge on your data, the pre-trained model cannot be directly used to calculate similarity, and it must be fine-tuned with contrastive learning before computing similarity.
  • If the accuracy of the fine-tuned model is still not high, it is recommended to use/fine-tune the cross-encoder model (bge-reranker) to re-rank top-k results. Hard negatives also are needed to fine-tune reranker.




    • 2. The similarity score between two dissimilar sentences is higher than 0.5

    The similarity score between two dissimilar sentences is higher than 0.5 -->

    Suggest to use bge v1.5, which alleviates the issue of the similarity distribution.

    Since we finetune the models by contrastive learning with a temperature of 0.01, the similarity distribution of the current BGE model is about in the interval \[0.6, 1\]. So a similarity score greater than 0.5 does not indicate that the two sentences are similar.

    For downstream tasks, such as passage retrieval or semantic similarity, what matters is the relative order of the scores, not the absolute value. If you need to filter similar sentences based on a similarity threshold, please select an appropriate similarity threshold based on the similarity distribution on your data (such as 0.8, 0.85, or even 0.9).



    3. When does the query instruction need to be used

    When does the query instruction need to be used -->



    For the bge-*-v1.5, we improve its retrieval ability when not using instruction. No instruction only has a slight degradation in retrieval performance compared with using instruction. So you can generate embedding without instruction in all cases for convenience. For a retrieval task that uses short queries to find long related documents, it is recommended to add instructions for these short queries. The best method to decide whether to add instructions for queries is choosing the setting that achieves better performance on your task. In all cases, the documents/passages do not need to add the instruction.



    Usage



    Usage for Embedding Model



    Here are some examples for using bge models with FlagEmbedding, Sentence-Transformers, Langchain, or Huggingface Transformers.

    #

    Using FlagEmbedding

    
pip install -U FlagEmbedding
    If it doesn't work for you, you can see FlagEmbedding for more methods to install FlagEmbedding.

    python
from FlagEmbedding import FlagModel
sentences_1 = ["样例数据-1", "样例数据-2"]
sentences_2 = ["样例数据-3", "样例数据-4"]
model = FlagModel('BAAI/bge-large-zh-v1.5', 
                  query_instruction_for_retrieval="为这个句子生成表示以用于检索相关文章：",
                  use_fp16=True) 
    Setting use_fp16 to True speeds up computation with a slight performance degradation
    
embeddings_1 = model.encode(sentences_1)
embeddings_2 = model.encode(sentences_2)
similarity = embeddings_1 @ embeddings_2.T
print(similarity)

    for s2p(short query to long passage) retrieval task, suggest to use encode_queries() which will automatically add the instruction to each query
    

    corpus in retrieval task can still use encode() or encode_corpus(), since they don't need instruction
    
queries = ['query_1', 'query_2']
passages = ["样例文档-1", "样例文档-2"]
q_embeddings = model.encode_queries(queries)
p_embeddings = model.encode(passages)
scores = q_embeddings @ p_embeddings.T
    For the value of the argument query_instruction_for_retrieval, see Model List.

    By default, FlagModel will use all available GPUs when encoding. Please set os.environ["CUDA_VISIBLE_DEVICES"] to select specific GPUs. You also can set os.environ["CUDA_VISIBLE_DEVICES"]="" to make all GPUs unavailable.

    #

    Using Sentence-Transformers



    You can also use the bge models with sentence-transformers:

    
pip install -U sentence-transformers

    python
from sentence_transformers import SentenceTransformer
sentences_1 = ["样例数据-1", "样例数据-2"]
sentences_2 = ["样例数据-3", "样例数据-4"]
model = SentenceTransformer('BAAI/bge-large-zh-v1.5')
embeddings_1 = model.encode(sentences_1, normalize_embeddings=True)
embeddings_2 = model.encode(sentences_2, normalize_embeddings=True)
similarity = embeddings_1 @ embeddings_2.T
print(similarity)
    For s2p(short query to long passage) retrieval task, each short query should start with an instruction (instructions see Model List). But the instruction is not needed for passages. 
    python
from sentence_transformers import SentenceTransformer
queries = ['query_1', 'query_2']
passages = ["样例文档-1", "样例文档-2"]
instruction = "为这个句子生成表示以用于检索相关文章："

    model = SentenceTransformer('BAAI/bge-large-zh-v1.5')
q_embeddings = model.encode([instruction+q for q in queries], normalize_embeddings=True)
p_embeddings = model.encode(passages, normalize_embeddings=True)
scores = q_embeddings @ p_embeddings.T


    #

    Using Langchain



    You can use bge in langchain like this: 
    python
from langchain.embeddings import HuggingFaceBgeEmbeddings
model_name = "BAAI/bge-large-en-v1.5"
model_kwargs = {'device': 'cuda'}
encode_kwargs = {'normalize_embeddings': True} 
    set True to compute cosine similarity
    
model = HuggingFaceBgeEmbeddings(
    model_name=model_name,
    model_kwargs=model_kwargs,
    encode_kwargs=encode_kwargs,
    query_instruction="为这个句子生成表示以用于检索相关文章："
)
model.query_instruction = "为这个句子生成表示以用于检索相关文章："


    #

    Using HuggingFace Transformers



    With the transformers package, you can use the model like this: First, you pass your input through the transformer model, then you select the last hidden state of the first token (i.e., [CLS]) as the sentence embedding.

    python
from transformers import AutoTokenizer, AutoModel
import torch

    Sentences we want sentence embeddings for
    
sentences = ["样例数据-1", "样例数据-2"]

    Load model from HuggingFace Hub
    
tokenizer = AutoTokenizer.from_pretrained('BAAI/bge-large-zh-v1.5')
model = AutoModel.from_pretrained('BAAI/bge-large-zh-v1.5')
model.eval()

    Tokenize sentences
    
encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')

    for s2p(short query to long passage) retrieval task, add an instruction to query (not add instruction for passages)
    

    encoded_input = tokenizer([instruction + q for q in queries], padding=True, truncation=True, return_tensors='pt')


    Compute token embeddings
    
with torch.no_grad():
    model_output = model(**encoded_input)
    
    Perform pooling. In this case, cls pooling.
    
    sentence_embeddings = model_output[0][:, 0]

    normalize embeddings
    
sentence_embeddings = torch.nn.functional.normalize(sentence_embeddings, p=2, dim=1)
print("Sentence embeddings:", sentence_embeddings)


    #

    Usage of the ONNX files



    python
from optimum.onnxruntime import ORTModelForFeatureExtraction  
    type: ignore


    import torch
from transformers import AutoModel, AutoTokenizer

    tokenizer = AutoTokenizer.from_pretrained('BAAI/bge-large-en-v1.5')
model = AutoModel.from_pretrained('BAAI/bge-large-en-v1.5', revision="refs/pr/13")
model_ort = ORTModelForFeatureExtraction.from_pretrained('BAAI/bge-large-en-v1.5', revision="refs/pr/13",file_name="onnx/model.onnx")

    Sentences we want sentence embeddings for
    
sentences = ["样例数据-1", "样例数据-2"]

    Tokenize sentences
    
encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')

    for s2p(short query to long passage) retrieval task, add an instruction to query (not add instruction for passages)
    

    encoded_input = tokenizer([instruction + q for q in queries], padding=True, truncation=True, return_tensors='pt')


    model_output_ort = model_ort(**encoded_input)

    Compute token embeddings
    
with torch.no_grad():
    model_output = model(**encoded_input)

    model_output and model_output_ort are identical




    Its also possible to deploy the onnx files with the infinity_emb pip package. 
    python
import asyncio
from infinity_emb import AsyncEmbeddingEngine, EngineArgs

    sentences = ["Embed this is sentence via Infinity.", "Paris is in France."]
engine = AsyncEmbeddingEngine.from_args(
    EngineArgs(model_name_or_path = "BAAI/bge-large-en-v1.5", device="cpu", engine="optimum" 
    or engine="torch"
    
))

    async def main(): 
    async with engine:
        embeddings, usage = await engine.embed(sentences=sentences)
asyncio.run(main())


    Usage for Reranker



    Different from embedding model, reranker uses question and document as input and directly output similarity instead of embedding. You can get a relevance score by inputting query and passage to the reranker. The reranker is optimized based cross-entropy loss, so the relevance score is not bounded to a specific range.

    #

    Using FlagEmbedding

    
pip install -U FlagEmbedding


    Get relevance scores (higher scores indicate more relevance): 
    python
from FlagEmbedding import FlagReranker
reranker = FlagReranker('BAAI/bge-reranker-large', use_fp16=True) 
    Setting use_fp16 to True speeds up computation with a slight performance degradation


    score = reranker.compute_score(['query', 'passage'])
print(score)

    scores = reranker.compute_score([['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.']])
print(scores)


    #

    Using Huggingface transformers



    python
import torch
from transformers import AutoModelForSequenceClassification, AutoTokenizer

    tokenizer = AutoTokenizer.from_pretrained('BAAI/bge-reranker-large')
model = AutoModelForSequenceClassification.from_pretrained('BAAI/bge-reranker-large')
model.eval()

    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.']]
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)

    Train



    BAAI Embedding



    We pre-train the models using retromae and train them on large-scale pairs data using contrastive learning. You can fine-tune the embedding model on your data following our examples. We also provide a pre-train example. Note that the goal of pre-training is to reconstruct the text, and the pre-trained model cannot be used for similarity calculation directly, it needs to be fine-tuned. More training details for bge see baai_general_embedding.



    BGE Reranker



    Cross-encoder will perform full-attention over the input pair, which is more accurate than embedding model (i.e., bi-encoder) but more time-consuming than embedding model. Therefore, it can be used to re-rank the top-k documents returned by embedding model. We train the cross-encoder on a multilingual pair data, The data format is the same as embedding model, so you can fine-tune it easily following our example. More details please refer to ./FlagEmbedding/reranker/README.md
