What is Fine-Tuning?
Further training of an existing model on your own examples so it adopts a format, style or narrow task. It ties you to that model version, and a newer base model may match it with a prompt, so test that first.
old + shims ≈ new alone · test first

In real work
Before approving fine-tuning for the claims classifier, the PM asked for a week of prompting on the newest model as the baseline it would have to beat.
In the illustration
Brass shims ground for one part make the old press stamp it perfectly. The new press is wheeled in and stamps the same part right with no shims at all.
Before we choose fine-tuning, test the cheaper path in your model: solve these 20 cases with a prompt and five examples, then list exactly which ones still fail and why.
