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)

RAG was introduced by Meta AI in 2020 as a method to improve Large Language Model (LLM) accuracy by grounding responses in retrieved, external data. eccentric_rag_2020_remaster

Recent developments emphasize modular pipelines and better evaluation protocols, moving away from simple "retrieve-and-generate" approaches. 2. Core Advantages of Modern RAG This report provides an overview of the landscape

Techniques such as Concept Bottleneck Models (CBM-RAG) are being applied to improve the interpretability of retrieved evidence, particularly in specialized fields like medical report generation. 4. Challenges and Future Directions human-defined knowledge systems.

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)?

It eliminates the need for expensive, frequent model fine-tuning.

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