我们总觉得AI变聪明，就是靠更多数据和更强算力，但今天我们要聊的几篇最新论文，揭示了另一条更聪明的捷径。我们将看到，顶尖的AI如何学会避免“走弯路”来提升思考质量，又如何像一个高效的项目经理，果断“叫停”慢任务，不再傻等。接着，我们会探索AI如何用一种“模糊”的艺术进行训练，像一个内部“诸葛亮会”一样进行多角度的头脑风暴，甚至变身“程序员”自己写代码来解决问题。这些研究不仅在优化AI，更是在颠覆我们对“高效思考”的理解，准备好一起脑力升级了吗？

00:06:22 AI效率革命：不等那个“最慢的同学”

00:11:34 AI思考的“模糊”艺术

00:17:02 AI的“分身术”：高手解决问题，靠的不是一条路走到黑

00:22:26 高手AI，不靠“背书”，靠“编程”
