LiberAI launches Liber-0 world action model, pretrained on 2.2 million hours of human experience

LiberAI has released Liber-0, a world action model pretrained on more than 2.2 million hours of human experience, combining large-scale human video, hand motions recorded with data gloves, and robot demonstrations, with the goal of giving robots generalizable manipulation capabilities. In an eight-task evaluation, a policy trained with 25% robot demonstrations plus 100% glove demonstrations scored 75.6 on progress, higher than the 72.8 scored using only all robot demonstrations. In a 60-task zero-shot evaluation, Liber-0 achieved a 36% success rate.
