Summary
This white paper delves into RAG, pairing large language models (LLMs) with external knowledge bases for trustworthy, efficient AI applications. It identifies common issues with LLM-only pipelines—like hallucination, outdated data, and limited contextual understanding—and presents RAG as a solution to enhance enterprise AI.
Industrial Landscape and Strategy
RAG strengthens AI by integrating dynamic data retrieval into generative processes, ensuring accurate, auditable, and scalable outputs.
Techniques like pre-retrieval indexing, hybrid search, and metadata filtering improve pipeline efficiency.
A modular approach allows enterprises to adapt RAG systems to their unique data and use-case requirements.
