Retrieval-augmented generation (**RAG**) in 2026 is no longer “embed PDFs and hope”: production systems use **hybrid retrieval, reranking, adaptive routing, and continuous evaluation** to keep answers grounded and cost-effective.[1][2][3] For developers and AI agents, the core design goal is to retrieve the *right* context at the *right* time, then prove that the system actually improved answer quality.[1][2][3]
