    "当使用 LLM 构建应用程序时，我从来没有在第一次尝试中就成功使用最终应用程序中所需的 Prompt。但这并不重要，只要您有一个好的迭代过程来不断改进您的 Prompt，那么你就能够得到一个适合任务的 Prompt。我认为在提示方面，第一次成功的几率可能会高一些，但正如上所说，第一个提示是否有效并不重要。最重要的是为您的应用程序找到有效提示的过程。\n",

    "因此，在本章中，我们将以从产品说明书中生成营销文案这一示例，展示一些框架，以提示你思考如何迭代地分析和完善你的 Prompt。\n",

    "如果您之前与我一起上过机器学习课程，您可能见过我使用的一张图表，说明了机器学习开发的流程。通常是先有一个想法，然后再实现它：编写代码，获取数据，训练模型，这会给您一个实验结果。然后您可以查看输出结果，进行错误分析，找出它在哪里起作用或不起作用，甚至可以更改您想要解决的问题的确切思路或方法，然后更改实现并运行另一个实验等等，反复迭代，以获得有效的机器学习模型。在编写 Prompt 以使用 LLM 开发应用程序时，这个过程可能非常相似，您有一个关于要完成的任务的想法，可以尝试编写第一个 Prompt，满足上一章说过的两个原则：清晰明确，并且给系统足够的时间思考。然后您可以运行它并查看结果。如果第一次效果不好，那么迭代的过程就是找出为什么指令不够清晰或为什么没有给算法足够的时间思考，以便改进想法、改进提示等等，循环多次，直到找到适合您的应用程序的 Prompt。\n"
