Generative AI refers to models that create new content, such as text, images, or music, based on learned patterns from existing data. Unlike traditional AI, which analyzes and classifies information, generative AI generates original outputs. Key models include GPT for text generation and GANs for image creation. These technologies are used in various industries, from content creation to healthcare, improving efficiency and innovation. As generative AI continues to evolve, it will impact how we interact with technology, enabling more creative and automated solutions, while raising ethical considerations about originality and ownership.
