Fine-Tuning vs. RAG: The $50,000 Mistake

Quick Answer: What is the difference between Fine-Tuning and RAG? Fine-tuning permanently alters a model’s core behavior and reasoning by updating its mathematical weights, making it ideal for specialized tasks but expensive to maintain. Retrieval-Augmented Generation (RAG) temporarily injects external,…
