Implementing a reranker layer in Retrieval-Augmented Generation (RAG) pipelines is crucial for improving answer precision, as initial retrieval stages may surface relevant documents but bury the best answer among less optimal ones. A production-ready reranker involves multiple components, including a broader initial retrieval set, a primary local cross-encoder model like BAAI's BGE-reranker-v2-m3, and a fallback managed API such as Cohere. Strategies like reciprocal rank fusion can combine scores from different sources, while latency and cost budgets, along with graceful degradation and an evaluation harness, are essential for robust deployment.
