What It Means
The process of training an existing AI model on a specific dataset to specialize its outputs. A fine-tuned model might write in a particular style, about a specific topic, or for a defined audience. The base model's general capabilities are preserved while being sharpened for the new purpose.
Why writers should care: Fine-tuned models can produce text that's harder to detect, because it's been trained to sound more "human" in specific domains.
In Context
Fine-tuning is how generic AI becomes domain-specific AI. A general model can be trained on medical journals to produce convincing clinical prose, or on legal filings to generate credible court documents. Each round of fine-tuning makes the output harder to distinguish from human expert writing in that field - which means domain experts are the most likely to face false accusations.
