Amazing-Coat5160 · reddit · 2026-07-16
A researcher in world models and robotics finds JEPA-based methods highly promising but seeks contrarian views to systematically map their flaws. Despite reading key papers by LeCun and others, and watching recent talks, the author is puzzled by LeCun's harsh critiques of LLMs and RL, while boldly framing JEPA as the "only promising next step." The author wants to uncover the biggest risks and drawbacks of JEPA compared to other world model paradigms.
