ChatGPT是目前最先进的AI聊天机器人，它能够理解图片和文字，生成流畅和有趣的回答。如果你想跟上AI时代的潮流，你一定要学会使用ChatGPT。如果你想了解OpenAI最新发布的GPT-4模型，以及它如何为ChatGPT聊天机器人带来更强大的功能，那么你一定不要错过OpenAI官网推荐的48种最佳应用场景，不管你是资深开发者、初学者，你都能够从0到1快速入门，并掌握他们。

Introduce 简介

Answer questions based on existing knowledge.
根据现有知识回答问题。

setting 设置

Engine：text-davinci-003
Max tokens：100
Temperature： 0
Top p：1
Frequency penalty：0.0
Presence penalty：0.0
Stop sequence：\n

说明：
0、Engine 设置定义了你要使用的模型，例如 text-davinci-003 是一个文本生成模型。这种模型可以根据输入的文本，生成新的、相关的文本。
1、Max tokens是指在请求中最多允许返回的 token 数目，比如你可以指定 chatGPT 返回最多 100个 token。这可以帮助你控制输出的内容大小，以便更好地控制响应速度和结果。一般1个token约4个字符或者0.75个单词
2、Temperature 是一个参数，用于控制 chatGPT 的输出。它决定了 chatGPT 在生成文本时会多么“随意”。值越高，chatGPT 生成的文本就越不可预测；值越低，chatGPT 生成的文本就越可预测。它在0.0到2.0之间，Temperature设置为0意味着ChatGPT将会生成更加保守的回复，即更少的随机性和更多的准确性，这可以帮助你在聊天中更好地控制语义，并且可以防止ChatGPT产生不相关的内容。
3、Top P 是随温度采样的替代方案，称为核采样，其中模型考虑具有top_p概率质量的标记的结果。因此0.1意味着仅考虑包括前10%概率质量的记号。通常建议更改此值或 temperature，但不要同时更改这两个值。
4、Frequency penalty是指在训练时，模型会根据词频来调整每个单词的重要性。它可以帮助模型更好地理解文本，并减少过拟合。介于-2.0和2.0之间的数字。正值会根据新标记在文本中的现有频率惩罚新标记，从而降低模型逐字重复同一行的可能性。Frequency penalty设置为0意味着模型不会对重复的词进行惩罚。它可以帮助模型生成更多的新词，而不是重复使用已有的词。
5、Presence penalty是指在ChatGPT中，一些预先定义的条件或者状态可能会影响机器人回答的质量，介于-2.0和2.0之间的数字。正值会根据新标记到目前为止是否出现在文本中来惩罚它们，从而增加模型谈论新主题的可能性。如果将 Presence penalty 设置为 0，则表示不会有任何惩罚。
6、Stop sequence 是一种设置，通过它可以确定你的聊天会话的结束标志。当你在 chatgpt 中设置 Stop sequence为 \n 时，表示你的聊天会话结束标志是换行符（\n）。
