Fine-Tuning
The process of taking a general AI model and giving it extra, specific training so it becomes an expert at one particular task.
In Plain English
Fine-tuning is like sending a general practice doctor to a specialized residency program to become a brain surgeon. The AI already knows the basics of language or imagery, but you want it to learn a specific style or rule set. A hospital might take a general AI and fine-tune it on medical records so it understands doctor shorthand. This makes the AI much more useful for specialized businesses.
Real-World Example
A law firm training an AI on its past legal briefs so the AI learns to write in the firm's specific legal style.
