What Does RAG Stand For in AI? Meaning, Examples, and How It Works

What Does RAG Stand For in AI: RAG architecture dashboard showing retrieval, knowledge bases, vector search, LLM generation, and source-grounded AI answers.

RAG stands for Retrieval-Augmented Generation in AI. It is a method that helps an AI system retrieve relevant information from external sources before generating an answer. In simple terms, RAG gives a language model access to documents, databases, or knowledge bases so its response can be more accurate, current, and useful. In simple terms RAG
