• DistillationTraining a small, cheap model to copy a big, expensive one so you get most of the skill at a fraction of the cost.
• EmbeddingA way of turning words or images into lists of numbers so a computer can tell which things have similar meanings.
• Emergent behaviourAbilities that show up in large models without anyone specifically training for them.
