What Is Generative AI? A Beginner’s Guide

Generative AI refers to models and systems that produce new outputs—such as text, images, audio, video, or code—from patterns learned during training. The result may be useful or novel-looking, but generation does not guarantee truth, originality, safety, or ownership. Generative AI is part of the broader field of artificial intelligence. Modern generative AI is largely

It gives information a defined structure and meaning for a particular task. A library system, for example, might represent books, their authors, individual copies and borrowing rules. Those representations help software answer questions
