rag

Definition

Retrieval-augmented generation: fetch passages relevant to the query, put them in the context window, and let the model answer from them. The appeal is swapping knowledge without retraining — private documents, recent events — and being able to cite sources. The ceiling is set by retrieval: if the wrong passages come back, the model answers confidently from the wrong passages.
