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。

TL;DR即，Too Long; Didn’t Read “太长;“没读过”，用来总结一篇很长的文本或文章。它通常用于互联网上，当人们想快速了解一篇文章的内容而不需要阅读所有内容时。ChatGPT强大的语言快速处理能力，就能为您完成这个需求。它不仅可以帮助您节省时间和精力，还可以帮助您更好地理解文章的内容。

Introduce 简介

TL;DR summarization TL;DR总结
Summarize text by adding a ‘tl;dr:’ to the end of a text passage. It shows that the API understands how to perform a number of tasks with no instructions.
通过添加’tl;dr：“到一段文字的结尾。它表明API理解如何在没有指令的情况下执行大量任务。

setting 设置

Engine：text-davinci-003
Max tokens：60
Temperature：0.7
Top p：1.0
Frequency penalty：0.0
Presence penalty：1.0

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60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 neutron star is the collapsed core of a massive supergiant star, which had a total mass of between 10 and 25 solar masses, possibly more if the star was especially metal-rich.[1] Neutron stars are the smallest and densest stellar objects, excluding black holes and hypothetical white holes, quark stars, and strange stars.[2] Neutron stars have a radius on the order of 10 kilometres (6.2 mi) and a mass of about 1.4 solar masses.[3] They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star density to that of atomic nuclei.
Tl;dr
中子星星是大质量超巨星坍缩的核心，它的总质量在10到25个太阳质量之间，如果恒星特别富含金属，可能会更大。[1]中子星是最小和密度最大的恒星，不包括黑洞和假设的白色、夸克星和奇异星。[2]中子星的半径约为10公里（6.2英里），质量约为1.4太阳质量。[3]它们是由大质量星星的超新星爆炸，加上引力坍缩，将核心压缩超过白色的密度，达到原子核的密度。

Neutron stars are the collapsed cores of massive supergiant stars, with a radius of around 10 kilometres and a mass of 1.4 solar masses. They are formed from the supernova explosion of a massive star combined with gravitational collapse, compressing the core beyond white dwarf star density.
中子星是大质量超巨星坍缩的核心，半径约10公里，质量为1.4个太阳质量。它们是由大质量星星的超新星爆炸结合引力坍缩形成的，将核心压缩到白色密度之外。
