Training a smaller, cheaper model to mimic the output of a larger one. "The 1B distillation of our 70B model runs fine on a laptop." Critical for shipping AI on devices, edge inference, and cost reduction. Trade-off: distilled models lose nuanced reasoning the parent could do.

"The 1B distillation of our 70B model runs fine on a laptop."
Origin: Tech / AI / developer industry term.
For parents

Distillation in AI is when a small model learns to copy a larger model's behaviour. Technical AI vocabulary. Not concerning. Outside AI, it just means concentrating something (as in alcohol production). If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in. Most slang of this kind moves through TikTok and group chats, so seeing it in your child's vocabulary just means they are plugged into normal teen internet culture.

For ESL learners

Distillation in AI is a technical process where a smaller "student" model is trained to mimic a larger "teacher" model. Use in machine-learning and AI research contexts. Formal equivalent: "knowledge distillation" (the full term). Common non-native mistake: confusing with the chemistry sense (separating liquids by boiling) or the metaphorical sense (capturing the essence of something). In AI contexts, the meaning is specifically the model-compression technique.

  • “Distillation can operate over a wide range of pressures from 0.”

  • “The distillation process concentrates the alcohol, so the resulting condensate has an increased alcohol by volume.”

  • “Distillation, also classical distillation, is the process of separating the component substances of a liquid mixture of two or more chemically discrete substances by selective boiling of the mixture and the condensation of the vapors in a still.”

  • “Liquor ( LIK-ər, sometimes hard liquor), spirit, distilled spirit, or spirituous liquor are alcoholic drinks produced by the distillation of grains, fruits, vegetables, or sugar that have already gone through alcoholic fermentation.”

For specific readers

Why is this section here?

Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
