Knowledge distillation

Also known as: distillation

Training

Knowledge distillation trains a small model (the student) to mimic a large model (the teacher). The student learns to reproduce the teacher’s outputs — and picks up a lot of its behavior at a fraction of the cost.

It’s a core reason small models keep getting surprisingly good:

  • Teacher: huge, expensive, high-quality.
  • Student: small, cheap, runs on your laptop.
  • Result: 8B model that behaves a lot like a 70B one.

The trick that powers local AI: distillation is how you get "near-frontier quality on a laptop". The small model is shadowing the big one.
