天学英语|时文阅读：“最强AI”ChatGPT爆火
近期，生成式AI再次点燃了人工智能的火炬，科技圈也刮起了一股名叫“ChatGPT”的风。ChatGPT是由OpenAI公司开发的一个人工智能聊天机器人程序，于2022年11月推出。它能够通过学习和理解人类的语言来进行对话互动交流，甚至能完成撰写邮件、文案、翻译、代码等任务。数据显示，截至2023年一月末，ChatGPT的月度用户数已突破1亿，成为史上消费者增长最快的应用。一起来看看吧。
There’s a new AI bot: ChatGPT, and you’d better pay attention, even if you aren’t into artificial intelligence. The tool is an AI chatbot system that OpenAI released in November 2022 to show off and test what a very large, powerful AI system can achieve.
ChatGPT remembers the thread of your dialogue, using previous questions and answers to inform its next responses. It derives its answers from huge volumes of information on the Internet. ChatGPT is built on top of the OpenAI GPT-3 family of large language models and is fine-tuned (a method of transfer learning) using both supervised and reinforcement learning（监督和强化学习）.
You can ask ChatGPT anything, like explaining physics, asking for birthday party ideas and getting programming（编程）help. Perhaps it’s not smart enough to replace all humans yet, but it can be creative, and its answers can sound downright authoritative. A few days after its launch, more than 1 million people were trying out ChatGPT. UBS analyst Lloyd Walmsley estimated in February 2023 that ChatGPT reached 100 million monthly users in January, accomplishing in 2 months what took TikTok about 9 months and Instagram two and a half years.
ChatGPT is free to use at the moment because it is still in its research phase. But when too many people hop onto the server（服务器）, it overloads and can’t process your request. It just means you should try visiting the site at a later time when fewer people are trying to access it. If you want to skip the wait and have reliable access, there is an option for you. As of Feb.1, 2023, OpenAI has a ChatGPT pro plan, ChatGPT Plus, which allows users to have general access even during peak times. This service does come at a cost of $20/month.
However, ChatGPT can not replace Google. ChatGPT is an artificial intelligence bot that provides solutions to your questions, but Google is a search engine in which you can search for as much information as possible. ChatGPT has limited knowledge due to its programming but Google has unlimited knowledge which is updated every day.
