The pattern where AI agents retrieve relevant content from a knowledge base before generating a response — grounding outputs in organizational knowledge and reducing hallucination.
Retrieval-Augmented Generation (RAG) is an AI architecture pattern in which a system retrieves relevant content from an external knowledge source — typically a vector database backed by organizational documents — and includes that content as context when generating a response. RAG combines the strengths of retrieval (factually grounded, current information) with the strengths of generation (fluent, context-aware response).
Without RAG, a language model's responses are limited to its training data and prone to hallucination on organization-specific topics. With RAG, responses are grounded in the organization's actual content. The architecture choice is between RAG (retrieve at query time) and fine-tuning (encode organizational knowledge in the model itself); RAG is more flexible for content that changes over time, fine-tuning can be more efficient for stable content. Many production deployments use both.
RAG is the dominant architecture for grounding enterprise AI in organizational knowledge. For workflows like internal FAQ resolution, policy lookup, IT helpdesk, and compliance monitoring, RAG is what makes the difference between generic AI responses and the organization's actual answers.
Internal HR FAQ agent that retrieves the relevant policy section before answering an employee's benefits question
Compliance monitoring agent that retrieves the applicable regulatory framework section when assessing a transaction
Contract review agent that retrieves historical clauses from approved templates when evaluating a new contract
Beth uses RAG as the foundation for knowledge-grounded workflows including internal FAQ, policy lookup, IT helpdesk, and compliance monitoring. Vector storage, embedding generation, and retrieval orchestration are part of the managed infrastructure. Drift detection over the underlying knowledge base ensures responses stay grounded as content changes.
Not always. RAG is better for content that changes over time and for transparent attribution (you can show which document the answer came from). Fine-tuning can be better for stable content and for embedding domain-specific reasoning patterns into the model. Many production deployments combine both.
