Traditional RAG can struggle with highly structured, human-defined knowledge systems.

The field has moved beyond basic RAG, diversifying into hybrid retrievers, iterative retrieval loops, and graph-based retrieval systems. eccentric_rag_2020_remaster

It eliminates the need for expensive, frequent model fine-tuning. diversifying into hybrid retrievers

This report provides an overview of the landscape following its introduction in 2020, based on systematic literature reviews published through 2025. 1. Executive Summary: RAG Evolution (2020–2025) iterative retrieval loops

The 2020-2025 maturation of RAG technology shows a distinct shift toward modular, graph-enabled, and interpretable systems. While initial RAG simply linked documents, the "remastered" approach focuses on navigating complex data structures to achieve trustworthy and accurate generative AI outputs. for RAG systems? Specific use cases (like RAG in healthcare or finance)?
