-\*: If you need to search the **long** relevant passages to a **short** query (s2p retrieval task), you need 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** need to be added to passages.
-## Frequently asked questions
-1. The similarity score between two dissimilar sentence is higher than 0.5
-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 sentence 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).
-2. When do the query instruction need to be used
-For a retrieval task that uses short queries to find long related documents,
-it is recommended to add instructions for these short queries.
-For other tasks, it is recommended not to add instructions.
-For example, in Quora task, which needs to use a short question to search another related short questions,
-the instruction is not recommended to add.
-The best method to decide whether to add instructions for queries is choosing the setting which can achieve better performance in your task.
-In all cases, the documents/passages do not need to add the instruction, only need to consider whether to add the instruction for queries.
-## Usage
-Here are some examples to use `bge` models with
-[FlagEmbedding](#using-flagembedding), [Sentence-Transformers](#using-sentence-transformers), [Langchain](#using-langchain), or [Huggingface Transformers](#using-huggingface-transformers).
-#### Using FlagEmbedding
-```
-pip install -U FlagEmbedding
-```
-If it doesn't work for you, you can see [FlagEmbedding](https://github.com/FlagOpen/FlagEmbedding/blob/master/FlagEmbedding/baai_general_embedding/README.md) 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', query_instruction_for_retrieval="为这个句子生成表示以用于检索相关文章：")
-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, please 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
-```
-The value of argument `query_instruction_for_retrieval` see [Model List](https://github.com/FlagOpen/FlagEmbedding/tree/master#model-list).
-FlagModel will use all available GPUs when encoding, please set `os.environ["CUDA_VISIBLE_DEVICES"]` to choose GPU.
-You also can set `os.environ["CUDA_VISIBLE_DEVICES"]=""` to make GPUs unavailable.
-#### Using Sentence-Transformers
-Using this model also is easy when you have [sentence-transformers](https://www.SBERT.net) installed:
-```
-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')
-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](https://github.com/FlagOpen/FlagEmbedding/tree/master#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')
-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-small-en"
-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："
-)
-```
-#### Using HuggingFace Transformers
-With 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 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')
-model = AutoModel.from_pretrained('BAAI/bge-large-zh')
-# 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)
-```

-## Train
-This section will introduce the way we used to train the general embedding.
-The training scripts are in [FlagEmbedding](https://github.com/FlagOpen/FlagEmbedding/blob/master/FlagEmbedding/baai_general_embedding/README.md),
-and we provide some examples to do [pre-train](https://github.com/FlagOpen/FlagEmbedding/blob/master/examples/pretrain/README.md) and [fine-tune](https://github.com/FlagOpen/FlagEmbedding/blob/master/examples/finetune/README.md).
-**1. RetroMAE Pre-train**
-We pre-train the model following the method [retromae](https://github.com/staoxiao/RetroMAE),
-which shows promising improvement in retrieval task ([paper](https://aclanthology.org/2022.emnlp-main.35.pdf)).
-The pre-training was conducted on 24 A100(40G) GPUs with a batch size of 720.
-In retromae, the mask ratio of encoder and decoder are 0.3, 0.5 respectively.
-We used the AdamW optimizer and the learning rate is 2e-5.
-**Pre-training data**:
-- English:
-    - [Pile](https://pile.eleuther.ai/)
-    - [wikipedia](https://huggingface.co/datasets/wikipedia)
-    - [msmarco](https://huggingface.co/datasets/Tevatron/msmarco-passage-corpus)
-- Chinese:
-    - [wudao](https://github.com/BAAI-WuDao/Data)
-**2. Finetune**
-We fine-tune the model using a contrastive objective.
-The format of input data is a triple`(query, positive, negative)`.
-Besides the negative in the triple, we also adopt in-batch negatives strategy.
-We employ the cross-device negatives sharing method to share negatives among different GPUs,
-which can dramatically **increase the number of negatives**.
-We trained our model on 48 A100(40G) GPUs with a large batch size of 32,784 (so there are **65,567** negatives for each query in a batch).
-We used the AdamW optimizer and the learning rate is 1e-5.
-The temperature for contrastive loss is 0.01.
-Besides, we add instruction to the query for s2p(short query to long passage) retrieval task in the training (add nothing to passages).
-For English, the instruction is `Represent this sentence for searching relevant passages: `;
-For Chinese, the instruction is `为这个句子生成表示以用于检索相关文章：`.
-In the evaluation, the instruction should be added for queries in retrieval task, not be added for other tasks.
-Noted that the instruction is not needed for passages.
-The finetune script is accessible in this repository: [FlagEmbedding](https://github.com/FlagOpen/FlagEmbedding/blob/master/FlagEmbedding/baai_general_embedding/README.md).
-You can easily finetune your model with it.
-**Training data**:
-- For English, we collect 230M text pairs from [wikipedia](https://huggingface.co/datasets/wikipedia), [cc-net](https://github.com/facebookresearch/cc_net), and so on.
-- For chinese, we collect 120M text pairs from [wudao](https://github.com/BAAI-WuDao/Data), [simclue](https://github.com/CLUEbenchmark/SimCLUE), and so on.
-**The data collection is to be released in the future.**
-## Schedule
-- [x] Chinese Massive Text Embedding Benchmark
-- [x] release baai-general-embedding models
-- [x] release codes for training
-- [ ] Multilingual model
-- [ ] Training Datasets
-- [ ] ...
-We will continually update the embedding models and training codes,
-hoping to promote the development of the embedding model community.

-FlagEmbedding can map any text to a low-dimensional dense vector which can be used for tasks like retrieval, classification,  clustering, or semantic search.
-And it also can be used in vector databases for LLMs.
-************* 🌟**Updates**🌟 *************
-- 09/12/2023: New Release:
-    - **New reranker model**: release a cross-encoder model bge-reranker-base, which is more powerful than embedding model. We recommend to use/fine-tune it to re-rank top-k documents returned by embedding models.

-\*: 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.
-\**: 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.
-## Frequently asked questions
-<details>
-  <summary>1. How to fine-tune bge embedding model?</summary>
-  <!-- ### How to fine-tune bge embedding model? -->
-Following this [example](https://github.com/FlagOpen/FlagEmbedding/tree/master/examples/finetune) to prepare data and fine-tune your model.
-Some suggestions:
-- Mine hard negatives following this [example](https://github.com/FlagOpen/FlagEmbedding/tree/master/examples/finetune#data-format), 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.
-</details>
-<details>
-  <summary>2. The similarity score between two dissimilar sentences is higher than 0.5</summary>
-  <!-- ### 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).
-</details>
-<details>
-  <summary>3. When does the query instruction need to be used</summary>
-  <!-- ### When does the query instruction need to be used -->
-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.
-</details>
-## Usage
-### Usage for Embedding Model
-Here are some examples for using `bge` models with
-[FlagEmbedding](#using-flagembedding), [Sentence-Transformers](#using-sentence-transformers), [Langchain](#using-langchain), or [Huggingface Transformers](#using-huggingface-transformers).
-#### Using FlagEmbedding
-```
-pip install -U FlagEmbedding
-```
-If it doesn't work for you, you can see [FlagEmbedding](https://github.com/FlagOpen/FlagEmbedding/blob/master/FlagEmbedding/baai_general_embedding/README.md) 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', query_instruction_for_retrieval="为这个句子生成表示以用于检索相关文章：")
-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](https://github.com/FlagOpen/FlagEmbedding/tree/master#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](https://www.SBERT.net):
-```
-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')
-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](https://github.com/FlagOpen/FlagEmbedding/tree/master#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')
-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-small-en"
-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')
-model = AutoModel.from_pretrained('BAAI/bge-large-zh')
-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 for Reranker
-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 score:
-```python
-from FlagEmbedding import FlagReranker
-reranker = FlagReranker('BAAI/bge-reranker-base', use_fp16=True) #use fp16 can speed up computing
-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, BatchEncoding, PreTrainedTokenizerFast
-tokenizer = AutoTokenizer.from_pretrained('BAAI/bge-reranker-base')
-model = AutoModelForSequenceClassification.from_pretrained('BAAI/bge-reranker-base')
-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](https://github.com/FlagOpen/FlagEmbedding/tree/master/examples/finetune).**
-We also provide a [pre-train example](https://github.com/FlagOpen/FlagEmbedding/tree/master/examples/pretrain).
-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](https://github.com/FlagOpen/FlagEmbedding/blob/master/FlagEmbedding/baai_general_embedding/README.md).
-### 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 pelease refer to [./FlagEmbedding/reranker/README.md](./FlagEmbedding/reranker/README.md)
