Your AI assistant is live, but it\u2019s either pulling outdated information or producing inconsistent responses. The real question is: do you fix it with real-time data access, or retraining the model itself?<\/p>\n

There are two primary approaches. The first is Retrieval-Augmented Generation<\/a> (RAG), an architecture that improves LLM outputs by retrieving relevant, up-to-date information from external sources at runtime. The second is fine-tuning, a machine learning technique that adapts a pre-trained model using domain-specific data to improve its behavior and outputs.<\/p>\n

Both approaches are valid, but the real decision comes down to trade-offs across cost, latency, control, and maintenance. Understanding these differences is critical to making the right call.<\/p>\n

In this blog, we\u2019ll break down their use cases, explore when a hybrid approach makes sense, and outline the key factors that should guide your decision whether that\u2019s RAG vs fine tuning, or a combination of both.<\/p>\n
