What Is Generative AI in Healthcare? 

Generative AI in healthcare is a technology that delivers output based on what they learn from data on medical information. These systems use language models and other technologies to do this.

Generative AI in healthcare is different from the kind of healthcare AI. The traditional kind just observes data and tries to guess what they are or what might happen. Whereas Generative AI in healthcare can actually create new ideas, and the output looks like a human.
