Concept

Retrieval-Augmented Generation

Retrieval-Augmented Generation, or RAG, gives a model relevant source material at request time. The system retrieves documents, selects useful passages, and places them in the model context. Retrieval quality, source freshness, and citations matter as much as the prompt.
