ChatGPT

ChatGPT is the artificial intelligence assistant from the company OpenAI: you write what you need in your own words and it answers you as in a conversation. It's useful for writing text, summarising documents, translating, brainstorming, explaining concepts, analysing data or helping with code, and it was the one that made this kind of tool popular at the end of 2022.

What confuses beginners is that ChatGPT doesn't "know" things like an encyclopaedia: it generates the answer that seems most likely, and that's why it sometimes makes up data with total confidence. Anything important, check it. Nor is ChatGPT, the app, the same as the GPT models running underneath, which keep changing version. And although you can use it without paying, features and limits vary by plan, so check the current terms before deciding whether to subscribe.

I moved from ChatGPT to Claude, although I still use OpenAI for some things. In "How I'm working with artificial intelligence" I explain the role each tool plays in my day-to-day, and in "Are chats still useful?" I ask myself what opening a chat window is still good for now that agents exist.
