# Generalist AI's GEN-1.5 Learns New Robot Tasks From Single 3-12 Second Demo

> Generalist AI has unveiled GEN-1.5, a robotics model built around a trick that sounds almost too convenient: show it a single three-to-twelve-second video of a task and it will attempt that task, with no retraining at all. The demo is fed straight into the model's context window as a kind of physical prompt, the same way you might paste an example into a chatbot. The numbers are early but striking. From one demonstration the system hit a 59% average success rate across ten tasks, rising to 83% after just ten training steps on about five minutes of data. That is a long way from reliable, but it points at a robotics future where teaching a machine a new chore looks more like showing it once than reprogramming it. Generalist, which raised $400M at a $2B valuation in June with backing from Nvidia and Bezos Expeditions, is chasing the same foundation-model-for-robots dream as several rivals. GEN-1.5's bet is that in-context learning, the thing that made language models feel general, can carry over to hands and motors too.
