Cohere-rerank-v3-multilingual
Version: 1
Cohere Rerank Multilingual is the market’s leading reranking model used for semantic search and retrieval-augmented generation (RAG). Rerank Multilingual supports 100+ languages and can be used to search within a language (e.g., search with a French query on French documents) and across languages (e.g., search with an English query on Chinese documents). Rerank enables you to significantly improve search quality by augmenting traditional key-word based search systems with a semantic-based reranking system which can contextualize the meaning of a user's query beyond keyword relevance. Cohere's Rerank delivers much higher quality results than just embedding-based search, lexical search and even hybrid search, and it requires only adding a single line of code into your application.
Rerank should be used as a ranker after initial retrieval (i.e. an initial search system finds the top-100 most relevant documents for a larger corpus of documents).
Rerank supports JSON objects as documents where users can specify at query time the fields (keys) that semantic search should be applied over.
- Context window of the model is 4096 tokens
- The max query length is 2048 tokens
