  "text": "Yann LeCun and his team dropped yet another paper!\n\n\"V-JEPA 2.1: Unlocking Dense Features in Video Self-Supervised Learning\" \n\nIn this V-JEPA upgrade, they showed that if you make a video model predict every patch, not just the masked ones AND at multiple layers, they are able to turn vague scene understanding into dense + temporal stable features that actually understands \"what is where\".\n\nThis key insight drove improvements in segmentation, depth, anticipation, and even robot planning.",
