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。

在这个AI大时代，如果不想被人颠覆，就要先颠覆别人。如果你颠覆不了别人，那你就努力运用ChatGPT提高你的技术水平和创造力。

ChatGPT可以利用自然语言理解和生成的能力，来处理非结构化数据。非结构化数据是指没有预定义的数据模型，不方便用数据库二维逻辑表来存储和查询的数据。ChatGPT可以将非结构化数据解析成结构化数据，例如表格、图表、列表等，从而方便用户进行分析和决策。例如，ChatGPT可以从一篇文章中提取出关键信息，并生成一个摘要表格；或者可以从一张图片中识别出物体，并生成一个标签列表。

Introduce 简介

Parse unstructured data 解析非结构化数据
Create tables from long form text by specifying a structure and supplying some examples.
通过指定结构并提供一些示例，从长格式文本创建表格。

setting 设置

Engine： text-davinci-003
Max tokens：100
Temperature：0
Top p：1.0
Frequency penalty：0.0
Presence penalty：0.0

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。通常建议更改此值或 Top P，但不要同时更改这两个值。
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。

Prompt 提示

A table summarizing the fruits from Goocrux: Goocrux的水果表格
There are many fruits that were found on the recently discovered planet Goocrux. There are neoskizzles that grow there, which are purple and taste like candy. There are also loheckles, which are a grayish blue fruit and are very tart, a little bit like a lemon. Pounits are a bright green color and are more savory than sweet. There are also plenty of loopnovas which are a neon pink flavor and taste like cotton candy. Finally, there are fruits called glowls, which have a very sour and bitter taste which is acidic and caustic, and a pale orange tinge to them.
| Fruit | Color | Flavor |
在最近发现的Goocrux行星上发现了许多水果。那里生长着neoskizzles，紫色的，吃起来像糖果。还有loheckles，这是一种灰蓝色的水果，非常酸，有点像柠檬。pounits是一个明亮的绿色，是更多的咸味比甜。也有大量的loopnovas，这是一个氖粉红色的味道，尝起来像棉花糖。最后，还有一种水果叫glowls，它有一种非常酸和苦的味道，是酸性和腐蚀性的，并有一种淡橙色调。
| 水果|颜色|风味|
