RAG vs. Fine-Tuning Explained — Which One Does Your AI Project Actually Need? | Master AI & ML Ep 24
Your company has years of internal knowledge and you want AI that knows all of it. Two paths exist — retrieval-augmented generation (RAG) and fine-tuning — and they solve genuinely different problems. Picking the wrong one wastes months and real money. This episode is the decision framework.
In this episode:
→ The core distinction: RAG changes what the model knows, fine-tuning changes how it behaves
→ How RAG actually works — chunking, embeddings, vector search, retrieval, generation
→ How fine-tuning actually works — additional training on labelled examples
→ The 5-question framework: data freshness, source citation, knowledge vs. behaviour, budget, data volume
→ Why RAG is the default starting point for most real business problems
→ The "do both" hybrid pattern used in mature production AI systems
This is Episode 24 of Master AI & Machine Learning — Module 5: Building with AI, Episode 2 of 7.
