AI Deep Dive 第6期：我们是否用错误方式构建世界模型
Rocket Alignment 和 World Mechanics 的创始人聊世界模型，讨论 JEPA、视频模型到底学没学到物理，做相关方向的可以听听。
本期播客邀请 World Mechanics 联合创始人 Sonia Joseph 探讨模型如何表征物理世界。讨论涵盖可解释性能否改进训练流程，以及仅靠语言是否足够支撑物理 AI。节目还对比了 JEPA 与专用世界模型的路线，并分析视频模型实际学到了哪些物理知识。
🚀 AI Deep Dive Episode 6: Are We Building World Models The Wrong Way?
@rocketalignment and World Mechanics co-founder @soniajoseph_ explore how models represent physics, whether interpretability could improve training and why language alone may not be enough for physical AI.
