     - **New reranker model**: release cross-encoder models `BAAI/bge-reranker-base` and `BAAI/bge-reranker-large`, which are more powerful than embedding model. We recommend to use/fine-tune them to re-rank top-k documents returned by embedding 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.

+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.**

 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](https://github.com/FlagOpen/FlagEmbedding/tree/master/examples/reranker).
