Reranking typically uses a CrossEncoder architecture that concatenates the query with candidate chunks for relevance scoring, and has become a standard coarse-ranking + fine-ranking two-stage architecture in industrial-grade RAG systems.

VerifiedReranking models such as Cohere Rerank and BGE-Reranker use a Cross-Encoder architecture to perform fine-grained relevance scoring between queries and documents, and are a key component in optimizing RAG precision.82% similarUnverifiedProduction-grade RAG systems commonly adopt a two-stage architecture of hybrid retrieval plus reranking, first using sparse retrieval (such as BM25) to recall candidate documents, then using a Cross-Encoder to rerank and select passages.82% similarUnverifiedIndustrial-grade RAG typically combines vector similarity retrieval (ANN algorithms such as HNSW) with BM25 keyword retrieval, and then uses a Rerank model (Cross-Encoder architecture) to re-rank the retrieved results.77% similarUnverifiedThe hybrid RAG pipeline of modern generative search engines typically first recalls 20 candidates with a bi-encoder, then re-ranks them precisely with a cross-encoder, while graph matching provides deterministic triples.74% similar
