Fine-Tuning

Level 3

Short Description

The process of further training a pre-trained model on a smaller, specialized dataset to adapt it to a specific task or domain.

Friendly Description: Fine-tuning is taking a model that already knows a lot and giving it some extra lessons in a particular subject. It's like hiring a great general doctor and then sending them through a short course to specialize in pediatrics. The base knowledge is still there; you've just sharpened it for a specific job.

Example: A law firm might take a general-purpose AI and fine-tune it on thousands of their past contracts. Afterward, the model is much better at spotting unusual clauses or summarizing legal documents in the exact tone the firm prefers.
