Knowledge distillation
Also called distillation, model distillation
What does “Knowledge distillation” mean?
Knowledge distillation: Training a smaller "student" model to imitate the outputs of a larger "teacher" model. The student is cheaper and faster to run and often keeps much of the teacher's ability on the tasks it was distilled for, at a fraction of the size and running cost.

What is an example of “Knowledge distillation”?
Many small, fast model versions offered by AI providers are created partly by distilling knowledge from their larger flagship models.
