The AI revolution is taking place in the field of business and Retrieval-Augmented Generation (RAG) plays a significant role in this revolution by boosting the performance of AI systems and adding new capabilities to them. By using large language models in combination with different external data sources, RAG allows systems to process and generate answers quickly and accurately. This technology is used by a number of sectors such as healthcare, finance, education, logistics, and enterprise software.
RAG technology's applications include AI virtual assistants, smart searching systems, processing papers tools, customer support automation solution, and knowledge management applications.
