Fine-Tuning
Domain: LLM Concepts
🎯 Motivation
A pre-trained model knows language but not how to follow instructions. Fine-tuning on instruction-response pairs teaches it to be helpful.
📋 Concrete Example
Take a pre-trained model. Show it thousands of (question, good answer) pairs. It adjusts to produce helpful responses. This is how a raw LLM becomes a chatbot.
🔗 Analogy
A general contractor who goes back to school to become a licensed electrician - they already know construction (pre-training), but fine-tuning adds specific skills for a specific job.
