# Retrieval-Augmented Generation Retrieval-augmented generation (RAG) retrieves relevant external records and supplies them to a model so an answer or artifact is grounded in a corpus rather than model parameters alone. Bryant's systems supply unusually strong source material for RAG because the documents preserve paths, frontmatter, explicit links, semantic annotations, source relations, and derived identifiers. A careful implementation should retrieve canonical sources and keep generated pages as projections rather than competing truths.
