Distillation

Compressing knowledge from a larger model into a smaller, faster one

What is Distillation?

A technique where a smaller 'student' model learns to replicate the behavior of a larger 'teacher' model, retaining most of the capability at a fraction of the cost and latency. Distillation is why you can run surprisingly capable models on a laptop. For builders, it means you don't always need the biggest model — you need the right-sized model for your task.

In plain words

"Think of it like a senior mentor transferring know-how to a junior — cheaper, faster, still sharp."

How it works

Key takeaways

  • Small model learns from a larger teacher model

  • Maintains quality while cutting inference cost

  • Core technique for deploying AI at scale

Real-world example

You run 10,000 queries through GPT-4 (the teacher) and collect its outputs. Then you fine-tune a smaller model like Llama 8B on those outputs. The small model captures most of GPT-4's quality at a fraction of the inference cost.
