Generative AI (Gen AI) refers to artificial intelligence systems that can transform human creativity into reality by generating various types of content, images, and 3D models. The development process involves data collection, model selection, training, evaluation, and deployment across multiple industries including arts, healthcare, and business automation. While Gen AI offers immense potential, challenges such as data requirements, ethical concerns, and intellectual property issues persist, along with promising future trends in personalization and human-AI collaboration.
