Cohere 推出了 Rerank 5，这是一个新的检索模型系列，提供 Pro 和 Fast 版本。这些模型旨在在大语言模型处理搜索结果之前对其进行重新排序，通过发送更少、更相关的 token 来提高效率。Rerank 5 引入了“Context Focus”（上下文聚焦）功能，用于识别文档中的特定相关段落，以及“calibrated relevance scores”（校准相关性分数），其功能类似于概率，增强了代理过滤结果和检测未找到相关信息的能力。Cohere 声称 Rerank 5 Pro 在各种基准测试中优于 Voyage AI 等竞争对手，尤其是在推理密集型查询和长文档方面。 AI

影响通过提高检索准确性和减少大语言模型的 token 使用量，增强 RAG 和代理性能。
