Its now clear how we might finally build the sort of truly capable robots that have for decades remained the stuff of science fiction.A few years ago, roboticists began marveling at the progress being made in large language models. Makers of those models could feed them massive amounts of textbooks, poems, manualsand then fine-tune them to generate text based on prompts.Its one thing to use AI to create sentences on a screen, but another thing entirely to use it to coach a physical robot in how to move about and do useful things. Now, roboticists have made major breakthroughs in that pursuit. Read the full story.James ODonnellFast-learning robots is one of our 10 Breakthrough Technologies for 2025, MIT Technology Reviews annual list of tech to watch.
