Retrieval-Augmented Generation (RAG) combines large language models (LLMs) with the ability to retrieve and incorporate relevant external information in NLP.
RAG addresses the limitations of traditional LLMs, providing more accurate and contextually relevant text by accessing real-time information.
The adoption of RAG is increasing, especially in customer service, content generation, and question-answering systems.
Challenges for RAG include data freshness, bias in retrieval, and variations in acceptance and implementation across different regions and cultures.
