Understanding RAG (Retrieval-Augmented Generation) and Fine-Tuning in AI

Image
  As artificial intelligence (AI) continues to evolve, we see a multitude of techniques designed to enhance model performance and adaptability. Two prominent methods, Retrieval-Augmented Generation (RAG) and Fine-Tuning , often come up in discussions about improving AI models, particularly in the context of large language models (LLMs). In this blog, we’ll delve into what these methods are, their use cases, and when you should consider using one over the other. What is Retrieval-Augmented Generation (RAG)? RAG is an advanced AI framework that combines retrieval systems with generative models to generate accurate and contextually relevant responses. Rather than relying solely on the knowledge encoded in the model’s parameters, RAG allows the model to query an external knowledge base to retrieve relevant documents or information before generating a response. How RAG Works: Query Understanding: The model takes an input query from the user. Document Retrieval: Using a retrieval co...
