Large Language Models are computer programs that have read a huge amount of text, like books, websites, and articles, so they can learn how people use language. Once trained, they can respond to questions, write stories, summarize information, or chat with people—almost like talking to a very smart robot. They don’t think or feel, but they’re good at guessing what words should come next in a sentence based on everything they’ve learned.

Generative AI is like an artist who creates a new painting from scratch after studying lots of other paintings—it makes something new, like a story, picture, or song. Predictive AI is more like a weather forecaster who looks at past weather data to guess what the weather will be tomorrow—it makes predictions based on patterns. So, generative AI creates, while predictive AI predicts.
