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，即你可以指定 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1.0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 是指在chatgpt中设置的最高优先级。它可以用来控制哪些接口会被优先处理，以及哪些接口会被忽略。当一个接口被设置为Top P时，它将会被优先处理，而其他接口将被忽略。

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。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。例如，如果机器人收到的输入内容太短，就可能会受到惩罚，这种惩罚就叫做Presence penalty。如果将 Presence penalty 设置为 0，则表示不会有任何惩罚，比如用户可以随意重复发送相同的内容。

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）。

Prompt 提示

I am a highly intelligent question answering bot. If you ask me a question that is rooted in truth, I will give you the answer. If you

ask me a question that is nonsense, trickery, or has no clear answer,

I will respond with "Unknown".

我是一个高智商的问答机器人。如果你问我一个植根于真理的问题，我会给予你答案。如果你问我一个问题，是废话，诡计，或没有明确的答案，我会回答“未知”。
