How AI Gets Specialized (Fine-Tuning Explained)
•December 30, 2025
Original Description
Day 9/42: What Is Fine-Tuning?
Yesterday, we compared base vs instruct models.
Today, we explain the key technique behind that shift.
Fine-tuning means training a model further on a small, high-quality dataset.
Not more knowledge.
Better behavior.
That’s how we get code assistants, legal copilots, and domain-specific chatbots.
Small tweaks.
Big practical impact.
Missed yesterday? Start there.
Tomorrow, we talk about something just as important as accuracy: alignment.
