Retrieval-Augmented Generationis an AI system that is a combination of information retrieval and generative AI. As opposed to an AI system that generates results based on the information it has acquired during training, the retrieval-augmented generation technique will retrieve relevant information from a trusted knowledge repository and feed that into the language model. The AI system can then utilize the retrieved information to generate a response. It is beneficial for businesses dealing with documents that are constantly updated, database, or even customer information.
