Meta AI has unveiled V-JEPA 2, a “world model” designed to help AI agents understand and predict how the physical world works. Trained extensively on video data and some robotic interaction, V-JEPA 2 allows robots to reason about gravity, object movement, and obstacle avoidance, enabling them to “think before they act.” This advancement brings AI closer to developing common sense about physics, a crucial step for building more intelligent and adaptable robots.
