It is multilingual, reranks English and non-English documents and semi-structured JSON within a 32,768-token query-plus-document window, and adds Context Focus, which returns the most relevant passages inside each document as scored character spans, plus calibrated relevance scores. Cohere says it outperforms its previous-generation Rerank 4 Pro. The Cohere API serves it as rerank-v5.0-fast.
