Overview

Good reranking model, consumes both a query and a list of documents to be ranked in relevance against the query. Is a closed source model that can be used via Cohere’s API.

Reranking models are designed to provide superior accuracy over retriever models but are much slower — so this model should not be used with more than a few hundred documents. Due to the slowness of rerankers, we recommend using them in a two-stage retrieval system, ie use a retrieval to pull in a smaller number of documents from a larger database and then rerank the smaller number of documents using a reranker.
