What is Generative AI? A Comprehensive Guide for 2025

Generative AI is a branch of artificial intelligence that focuses on creating content. Unlike traditional AI systems designed to analyze data or make decisions based on rules, generative AI models can produce new data—whether text, images, audio, or other media types—based on the patterns they’ve learned from existing information. These models use complex neural networks, particularly those in the realm of deep learning, to generate outputs that resemble human-created content. This ability to create new, coherent outputs has opened up various possibilities across different industries.
