Lesson 3 of 10 · Fine-Tuning vs Prompting: What to Choose
In this lesson. Facts that change should not live in weights.
What you will learn
- Changing facts
- Freshness
- Store not weights
Walkthrough
You will put changing facts in a store. Fine-tuning facts is how you get stale models. RAG versus FT is a freshness question.
Work through the ideas in order. After each point, pause and connect it to a task you already do — a document, a workflow, or a feature you own. The goal of Fine-Tuning vs Prompting: What to Choose is usable skill, not a pile of notes.
If something is unclear, rewrite it in your own words before you continue. Teaching the step back to yourself is the fastest way to see gaps.
Practice
List five facts in your product that must not be fine-tuned.
Keep the first attempt small. A finished example you can reuse beats a perfect plan you never run.
