AI & models
Fine-tuning
Taking an already-trained model and training it a little more on a narrow set of examples, so it gets better at one specific job — a certain writing style, a particular kind of task. A tune-up, not a rebuild.
Why it matters
Part of How AI actually works → You'll hear "a fine-tuned model." It means a general model nudged toward a specialty — most people never need to do it to use Claude well.
