RAG pipelines gain precision with production-ready reranker layer

A developer shares a production-ready reranker layer for Retrieval Augmented Generation (RAG) pipelines to address issues where relevant information is buried deep in search results. The proposed solution involves a two-stage retrieval process, first fetching a larger set of candidates (50-100) and then using a reranker model to re-score these candidates for better precision. This approach aims to improve answer quality by ensuring the most relevant documents are prioritized for the LLM, while also detailing strategies for cost management, latency, and graceful degradation.
