RAG stands for Retrieval-Augmented Generation. It is a pattern that gives a language model access to information outside its training data by fetching relevant documents at query time and including them in the prompt. Instead of memorizing facts, the model reasons over retrieved snippets, which makes answers more accurate, current, and traceable. A typical RAG pipeline has four stages. First, documents are split into chunks and converted into embeddings using an embedding model. Second, those embeddings are stored in a vector database. Third, when a user asks a question, the system embeds the query and searches the database for the closest chunks. Finally, the retrieved chunks are added to the prompt as context, and the model generates an answer grounded in that evidence. RAG is especially useful when answers depend on private data, such as internal wikis, support tickets, or product documentation. It also reduces hallucination because the model can cite the retrieved text. Teams often tune RAG by changing chunk size, overlap, reranking algorithms, and query rewriting strategies.
