你有没有想过，我们能用一套“知识探针”给大模型做一次精确的“脑容量”CT扫描吗？或者，当AI不再满足于讲一个完美的成功故事，而是把所有失败的教训都记录下来，科学研究会变成怎样一个“活物”？本期节目，我们将从五篇最新论文出发，看看AI如何学会“变脸”戏法，又是如何用“笨办法”实现反超，以及，如何只用一部手机就让一只螃蟹学会跳街舞。

00:00:31 如何给AI大模型做一次“脑容量”CT扫描？

00:08:25 让一只螃蟹学会跳街舞，总共分几步？

00:13:47 让知识“活”起来，科研的下一种形态

00:20:47 AI的“变脸”戏法，我们以为的安全，可能只是没对上“暗号”

00:27:26 AI进化新思路，为什么“笨办法”反而更聪明？
