The US government just accused a Chinese AI company of copying an American model, and threatened sanctions over it. Whether or not the claim holds up, it's worth understanding what's actually being alleged, because the word at the center of it, distillation, is about to come up a lot. Here's the plain version.
What distillation means
Model distillation is training a new model using the outputs of an existing one. Instead of learning purely from raw data, the new model learns by copying how a stronger "teacher" model responds. Done legitimately, it's a normal technique for making smaller, cheaper models. Done against someone else's commercial model without permission, it's a way to clone a lot of that model's behavior on the cheap, and it usually violates the terms of service.
That's the core of the accusation: that one company used another company's model as an unpaid teacher.
