The Download: how babies can teach AI, and new mRNA vaccines

Human babies are far better at learning than even the very best large language models. To be able to write in passable English, ChatGPT had to be trained on massive data sets that contain millions upon millions of words. Children, on the other hand, have access to only a tiny fraction of that data, yet by age three they're communicating in quite sophisticated ways. A team of researchers at New York University wondered if AI could learn like a baby. What could an AI model do when given a far smaller data set--the sights and sounds experienced by a single child learning to talk?
