There's a new AI program: ChatGPT. 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 idea of your dialogue, using previous questions and answers to inform its next responses. It gets 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 help. Perhaps it's not smart enough to replace all humans yet, but it can be creative, and its answers can sound 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 stage. But when too many people hop onto the server（服务器）, it is overloaded 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 cannot 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.
