What you'll learn
How LLMs are trained to make sense of fine-tuning.
We’ll cover training stages, where fine-tuning fits, and why it shapes tone and behavior more than knowledge.
What to try before fine-tuning.
A better prompt, examples, or access to the right documents may solve it. We’ll show you how to tell.
How to decide whether fine-tuning is worth it.
We’ll go over the data it needs, what it costs to build and maintain, and how to check that it actually helped.
Why this topic matters
Fine-tuning is often seen as the way to turn a general model into your own, so teams put time and money into it. The results are often disappointing, because the problem needed a better prompt or access to the right information rather than a retrained model. Knowing what fine-tuning can and can’t do helps you choose the simpler option when it’s enough and recognize the cases where fine-tuning is the right call.
