Fine-Tuning, Honestly
Usually the wrong answer. Here is how to know when it is right.

Prompt, then few-shot, then RAG, then fine-tune — in that order, with the receipts for why each rung is cheaper and more reversible than the next. You will watch overfitting happen on the page: training error falling while held-out error climbs, memorisation with a face on it. And an honest closer about the short list of cases where fine-tuning genuinely wins.
Press play and a teacher talks you through the whole build, with a read-along transcript that highlights as it speaks.
Working, offline interactives — not screenshots. When the narration says "try it", the thing is right there.
No account, no app, no subscription. It runs from a single HTML file and will still run in ten years.
Every number is computed live on the page from inputs you can edit. Nothing is asserted that cannot be checked.
Written for builders about to spend money changing weights.
Work the decision ladder before spending a cent
Build a dataset that improves rather than poisons a model
Recognise overfitting from the curves, not from hope
Tell the rare genuine fine-tuning case from the common mistake

The free preview is not a teaser: those chapters are complete, and the paid chapters are physically absent from the preview file rather than hidden behind a script.
What this hour is, how to use the page, and the interactive demo you will keep coming back to.
