Generative AI is a subset of artificial intelligence that can create new content, such as text, images, music, or even entire products, by learning from existing data. Instead of just following pre-set rules, it uses patterns from the data it's trained on to generate something entirely new. For instance, imagine an AI trained on thousands of T-shirt designs. Generative AI in eCommerce can create original T-shirt designs by combining patterns, styles, and colors.
