RAG is a powerful approach in natural language processing (NLP) that combines information retrieval and text generation to provide more accurate and contextually relevant responses to queries or prompts by augmenting prompts with proprietary data, allowing AI models to access information that they weren't trained on. This method enables organizations to unlock the full potential of large language models (LLMs), providing factual accuracy in scenarios such as research, customer support, and content generation without requiring retraining or fine-tuning of the LLMs. By leveraging RAG with proprietary data, organizations can gain a competitive edge with reliable and accurate AI-generated output.
