Yann LeCun's World Model Gets Formal Proof — But Paired Benchmark Shows All Current Architectures Collapse Under Minor Perturbations

TechTimes·medium signal

Two AMI Labs preprints posted in late May formally proved when LeCun's JEPA architecture can recover real-world structure, and a paired 'stable-worldmodel' benchmark (arXiv May 20) found that every tested world-model architecture — not just JEPA — drops sharply under minor visual perturbations like color changes to the agent or background. This is significant because it provides the first formal theoretical backing for LeCun's anti-LLM thesis while simultaneously showing that no existing approach, including his own, is robust enough for real-world deployment.
