Overview

Cohere Rerank v3.5 is an iteration in Cohere’s Rerank model series, building upon Cohere Rerank v3.0. Rerank has improved dramatically in cases where the user is expressing explicitly or implicitly constraints on what they would like returned. Rerank’s ability to rank results based on this has considerably improved performance on queries that have traditionally been the hardest for retrieval systems. Other key features include multilingual support for over 100+ languages and SOTA performance in domains like finance, hospitality and many more. The model has a context length of 4096 tokens.
