What is ChatGPT?

什么是ChatGPT？

In its own description, ChatGPT is “an AI-powered chatbot developed by OpenAI, based on the GPT (Generative Pretrained Transformer) language model. It uses deep learning techniques to generate human-like responses to text inputs in a conversational manner.”

用它自己的话说，ChatGPT是一款“由OpenAI基于GPT（生成式预训练转换器）语言模型开发的人工智能聊天软件”。该软件会利用深度学习技巧以对话的方式对文本输入产生类似于人类的反应。

ChatGPT is an AI chatbot developed by San Francisco-based startup OpenAI. OpenAI was co-founded in 2015 by Elon Musk and Sam Altman and is backed by well-known investors — most notably Microsoft. 

ChatGPT是一款由位于旧金山的初创公司OpenAI所研发的人工智能聊天工具。OpenAI由Elon Musk和Sam Altman于2015年共同创建并获得了知名投资者的支持-最著名的要数微软。

It is one of several examples of generative AI. These are tools that allow users to enter written prompts and receive new human-like text or images and videos generated by the AI.

ChatGPT是若干生成式人工智能工具中的一个。用户可以通过这些工具输入相应的提示并根据提示获得由人工智能生成的、更接近人类回答的文本、图像和视频。

In ChatGPT’s case, the service is a text-based tool that can produce human-like responses to user requests — from poetry in the style of William Shakespeare to advice on what to do for a child’s birthday party.

ChatGPT是一款以文本为主的智能工具，它能够根据用户的需求给出更贴近人类的回答-比如莎士比亚风格的诗歌，以及给出为孩子办一场生日宴会方面的建议。

What’s so special about it?

ChatGPT有哪些特别之处？

ChatGPT is powered by a large language model, or LLM, meaning it’s programmed to understand human language and generate responses based on large corpora of data.

ChatGPT由大型语言模型或LLM支持，这意味着它可以理解人类的语言并根据海量数据生成回答。

ChatGPT’s LLM is called GPT-3.5. It is an upgrade of OpenAI’s GPT-3 language model.

ChatGPT的LLM被称为GPT-3.5，是OpenAI GPT-3语言模型的升级版。

With a whopping 175 billion parameters, GPT-3 is one of the largest and most powerful language processing AI models to date.

拥有多达1750亿的海量参数，GPT-3是迄今为止规模最大、功能最强的语言处理人工智能模型之一。

Whopping：巨大的；很大的

What makes ChatGPT so impressive is its ability to produce human-like responses, thanks in no small part to the vast amounts of data it is trained on.

ChatGPT之所以如此令人印象深刻是由于它能够产生类似于人类的反应，这在很大程度上归功于它经过海量数据的训练。

The chatbot signed up 1 million in the five days after its release, according to a Dec. 5 tweet from Altman. By January, ChatGPT had amassed 100 million monthly active users only two months into its launch, making it the fastest-growing consumer application in history, according to a UBS note published last week.

据Altman在12月5日发布的推特，自发布起来，chatbot的注册用户在5天之内就达到了1百万。根据瑞银上周发布的说明，截至1月，ChatGPT在推出后仅2个月就已经拥有1个亿的月活跃用户，ChatGPT也因此成为历史上发展最快的消费应用程序。

How good is ChatGPT, really?

ChatGPT到底有多好？

ChatGPT has its limitations. Responses from the chatbot can contain factual inaccuracies. For example, it can invent fictitious historical names and books that don’t exist, or fail to solve certain math problems.

ChatGPT也有其局限性。Chatbot的回答可能存在事实误差。比如说，它会编出虚构的历史人名和书籍，或者无法解答某些数学问题。

For now, experts say generative AI isn’t yet capable of achieving human-like, “general” intelligence.

截至目前，专家们表示，生成式人工智能还无法拥有类似于人类的“一般”智力。

Artificial general intelligence, or AGI, is often considered the holy grail of the AI community. It most commonly refers to the ability of an intelligent agent to understand or learn any intellectual task that a human being can.

人工综合智能或AGI通常被视为人工智能领域的“圣器”，其通常是指智能代理人理解或掌握任何人类能够做到的智力工作的能力。
