technique for grounding language models
Retrieval-augmented generation, or RAG, is a technique that retrieves relevant documents from a knowledge base and places them in a language model prompt, so answers are grounded in your content rather than in model memory alone.
A working RAG system is a pipeline: chunking, embedding, indexing, retrieval with filters, reranking, prompt assembly and an evaluation loop that measures whether retrieval actually helped.
RAG is the default way to put a language model on top of private content. Long context windows reduce but do not remove the need for it, and evaluation remains the differentiator.
