ChatGPT is a generative predictive text tool built by the artificial intelligence research company OpenAI (https://openai.com). ChatGPT allows a user to ask a question or describe a prompt and through a conversational interaction, ChatGPT will provide answers to the queries. Because the tool is a Large Language Model (LLM) - meaning it was trained on a large corpus of information - and it's responses are based on it's ability to calculate probabilities, it may put words together that sound like answers, but it DOES make mistakes.
