Model overview
The bge-reranker-v2-m3 model is a lightweight reranker model from BAAI that possesses strong multilingual capabilities. It is built on top of the bge-m3 base model, which is a versatile AI model that can simultaneously perform dense retrieval, multi-vector retrieval, and sparse retrieval. The bge-reranker-v2-m3 model is easy to deploy and provides fast inference, making it suitable for a variety of multilingual contexts.
Model inputs and outputs
The bge-reranker-v2-m3 model takes as input a query and a passage, and outputs a relevance score that indicates how relevant the passage is to the query. The relevance score is not bounded to a specific range, as the model is optimized based on cross-entropy loss. This allows for more fine-grained ranking of passages compared to models that output similarity scores bounded between 0 and 1.
Inputs
- Query: The text of the query to be evaluated
- Passage: The text of the passage to be evaluated for relevance to the query
Outputs
- Relevance score: A float value representing the relevance of the passage to the query, with higher scores indicating more relevance.
Capabilities
The bge-reranker-v2-m3 model is designed to be a powerful and efficient reranker for multilingual contexts. It can be used to rerank the top-k documents retrieved by an embedding model, such as the bge-m3 model, to further improve the relevance of the final results.
What can I use it for?
The bge-reranker-v2-m3 model is well-suited for a variety of multilingual information retrieval and question-answering tasks. It can be used to rerank results from a search engine, to filter and sort documents for research or analysis, or to improve the relevance of responses in a multilingual chatbot or virtual assistant. Its fast inference and strong multilingual capabilities make it a versatile tool for building language-agnostic applications.
Things to try
One interesting aspect of the bge-reranker-v2-m3 model is its ability to output relevance scores that are not bounded between 0 and 1. This allows for more nuanced ranking of passages, which could be particularly useful in applications where small differences in relevance are important. Developers could experiment with using these unbounded scores to improve the precision of their retrieval systems, or to surface more contextually relevant information to users.
Another interesting thing to try would be to combine the bge-reranker-v2-m3 model with the bge-m3 model in a hybrid retrieval pipeline. By using the bge-m3 model for initial dense retrieval and the bge-reranker-v2-m3 model for reranking, you could potentially achieve higher accuracy and better performance across a range of multilingual use cases.

bge-reranker-base
BAAI
bge-reranker-base is a cross-encoder model designed for re-ranking search results in Chinese and English text. This model works in tandem with embedding models like bge-large-en-v1.5 and bge-large-zh-v1.5 to improve search accuracy. As part of the BAAI FlagEmbedding family, it offers enhanced performance compared to pure embedding approaches. Model Inputs and Outputs The model takes pairs of text sequences and evaluates their relevance to each other. It processes both the query and potential matches to generate accurate ranking scores. Inputs Query text**: The search query or question Document text**: The candidate text to be ranked Text pairs**: Multiple query-document combinations for batch processing Outputs Relevance score**: A numerical score indicating the relevance between query and document Ranked results**: Ordered list of documents based on relevance scores Capabilities The cross-encoder architecture enables direct comparison between text pairs for precise relevance assessment. The model supports both Chinese and English content and can handle various text lengths. It excels at refining search results by re-ranking candidates identified by faster embedding models. What can I use it for? This reranker enhances search quality for applications like document retrieval, question answering, and content recommendation. It pairs well with bge-base-en-v1.5 and bge-small-en-v1.5 for building search systems. For higher accuracy requirements, consider the larger bge-reranker-large variant. Things to Try Use the model to improve search result quality by re-ranking the top results from an initial embedding search. Apply it to tasks like finding relevant documentation, matching questions to answers, or filtering content recommendations. The model works best when processing a focused set of candidates rather than an entire document collection.

bge-small-en
BAAI
The bge-small-en model is a small-scale English text embedding model developed by BAAI (Beijing Academy of Artificial Intelligence) as part of their FlagEmbedding project. It is one of several bge (BAAI General Embedding) models that achieve state-of-the-art performance on text embedding benchmarks like MTEB and C-MTEB. The bge-small-en model is a smaller version of the BAAI/bge-large-en-v1.5 and BAAI/bge-base-en-v1.5 models, with 384 embedding dimensions compared to 1024 and 768 respectively. Despite its smaller size, the bge-small-en model still provides competitive performance, making it a good choice when computation resources are limited. Model inputs and outputs Inputs Text sentences**: The model can take a list of text sentences as input. Outputs Sentence embeddings**: The model outputs a numpy array of sentence embeddings, where each row corresponds to the embedding of the corresponding input sentence. Capabilities The bge-small-en model can be used for a variety of natural language processing tasks that benefit from semantic text representations, such as: Information retrieval**: The embeddings can be used to find relevant passages or documents for a given query, by computing similarity scores between the query and the passages/documents. Text classification**: The embeddings can be used as features for training classification models on text data. Clustering**: The embeddings can be used to group similar text documents into clusters. Semantic search**: The embeddings can be used to find semantically similar text based on their meaning, rather than just lexical matching. What can I use it for? The bge-small-en model can be a useful tool for a variety of applications that involve working with English text data. For example, you could use it to build a semantic search engine for your company's knowledge base, or to improve the text classification capabilities of your customer support chatbot. Since the model is smaller and more efficient than the larger bge models, it may be particularly well-suited for deployment on edge devices or in resource-constrained environments. You could also fine-tune the model on your specific text data to further improve its performance for your use case. Things to try One interesting thing to try with the bge-small-en model is to compare its performance to the larger bge models, such as BAAI/bge-large-en-v1.5 and BAAI/bge-base-en-v1.5, on your specific tasks. You may find that the smaller model provides nearly the same performance as the larger models, while being more efficient and easier to deploy. Another thing to try is to fine-tune the bge-small-en model on your own text data, using the techniques described in the FlagEmbedding documentation. This can help the model better capture the semantics of your domain-specific text, potentially leading to improved performance on your tasks.
