这句话需要展开解释一下。人们使用 GPT 的方式可能千差万别，但在很抽象的层面上，它仍然可以大致分成两类任务：请求它评估（某个方案的好坏，某段文字的优劣，etc.），或者请求它输出（做一个新的方案，给出一个建议，自己写一段作品，etc.）。对任何智能来说，这两类任务都是相关但不相同的。比如一个人可能是个美食家，但炒个鸡蛋也会炒糊。可能有极好的文字品味，但写出来的小说很幼稚。可以在评论别人的方案的时候充满洞见，但自己一上手就磕磕绊绊。（甚至也有反过来的情形，一个人可以完全不擅长评论，但自己做就做得很好。当然这是比较罕见的例子。这个区别当然一方面是因为知易行难，但还有一个根本问题在于这两者追求的不是一回事。前者追求的是对数据分布的深刻理解，希望达到全局上的客观综摄。后者追求的则是在这个分布里试图获得一个不平凡的结果，换句话说，是对这个分布的一个抵抗而非服从。没有诗人，哪怕乾隆，写诗是为了想写出一首平庸的诗。大家想写的是传颂千秋的诗——虽然每个人都这么想的结果仍然是大家写出来的是都很平庸，但那是不得已。也就是说，评估需要的是理解分布，而创造追求的是打破分布，或者说，是在另一个自己内心的理想分布中做采样。一个人才华越高，这个自己内心的理想分布同现实分布之间的 distortion 就越大，自己也就越能强行逃脱现实的引力。正是因为一代一代有天赋有才华的人的不懈努力和接力，投入自己的 ego ...继续阅读 (20)
