Generative AI refers to models or algorithms that create brand-new output such as text, photos, videos, code, data, or 3D renderings from the vast amounts of data they are trained on. The models learn the patterns and structure of their input training data and then generate new content based on those patterns. The term generative is used to describe this type of AI because it is capable of generating new and original content, rather than simply recognizing and classifying existing data. Generative AI has become popular due to its ability to produce high-quality content quickly and at scale, as well as its potential to revolutionize various industries.
