What is ChatGPT?

ChatGPT is a popular AI chatbot from the company OpenAI that lets you write texts, ask questions and summarize, all in plain language.

ChatGPT is a chat window where you type something and get an answer right away. It runs on a language model (an LLM). You can have it draft an email, summarize a long text or explain a complicated subject. There is a free version and a paid version with more features.

What this means for you

For many people, ChatGPT is their first taste of AI. It is a good place to practice, as long as you check the answers yourself.

Put precisely

ChatGPT is the tool, not the model. OpenAI swaps the model underneath from time to time, and that changes what the tool can do.

Common misconception

That ChatGPT looks up answers in a database. It generates text, and it only searches when the search feature is switched on.
