Since the 1950s, with the development of computers and information technology, especially the breakthroughs in deep learning technology, Generative AI has gradually evolved from a single language generation to a multimodal and embodied direction. And has shown a strong vitality through pretrain and prompt, with data-driven and powerful generative capability, deep learning and highly customised, intelligent simulation and real-time efficiency. It has the characteristics of data-driven and powerful generative ability, deep learning and highly customisable, intelligent simulation and real-time efficiency. A clear overview of the development of Generative AI will help promote agile governance and the development of technology for good while empowering various industries.
