Reranker

Available in Classic and VPC

Reranker evaluates the relevance of retrieved documents to a query to select the most relevant documents, which are then summarized and condensed to generate RAG answers. By selectively using only documents that are highly relevant to the user query, rather than the entire search document, you can efficiently reduce token consumption while still achieving highly reliable results.
