Generative AI multi - modal creation, as a cutting - edge direction in the current field of artificial intelligence, is showing a vigorous development trend. At the technical level, it has achieved the integration of text and various other modalities such as images and audio, and has achieved remarkable results in many fields such as art, entertainment, and education. However, this emerging mode of creation also brings many copyright challenges, such as difficulties in defining copyright ownership, incompatibility of the existing copyright system, and impacts on the copyright market. In response to these challenges, we can improve the rules of copyright ownership and the scope of protection at the legal level, use technical means such as blockchain to confirm rights and track, and establish industry norms to guide development. Looking to the future, generative AI multi - modal creation technology will continue to deepen cross - modal integration, and the copyright system also needs to develop in a coordinated manner to achieve effective protection and standardization of creation, and then promote positive changes in social culture and the economic industry.Keyword: Generative AI; Multimodal Creation; Copyright Challenges; Countermeasures; Development Trends
