Retrieval-Augmented Generation () allows language models to use external documents when answering questions. Instead of relying solely on , a system retrieves relevant information at inference time and provides it as additional context before generating a response. This improves accuracy and freshness, but it also changes how trust works in the system. This room covers how systems work, where their unique security risks appear, and how attackers exploit retrieval, context injection, and trust boundaries to manipulate model outputs.
