ChatGPT is a type of AI model developed by OpenAI that can generate human-like text. It isn’t magic, and it isn’t sentient. It’s a tool that predicts the next word in a sentence, based on patterns it has seen in a massive amount of text data. GPT stands for Generative Pre-trained Transformer. It generates text, has been trained beforehand on a vast dataset, and is built on a transformer architecture, which is a specific kind of neural network designed for language understanding.
