About Cohere Rerank 5 Fast
Cohere Rerank 5 Fast is Cohere's low-latency, high-throughput reranking model, released October 21, 2026 with the Rerank 5 generation. 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.
