In the field of design, AIGC (Artificial Intelligence Generated Content) technology is a technology that uses artificial intelligence algorithms to automatically generate a variety of content, such as images, animation, text and music, and it promotes the digital transformation of traditional design with its intelligent technology of big data analysis, algorithmic optimisation and automated generation. This paper analyses the current development of AIGC (Artificial Intelligence Generated Content) technology and its potential in art creation, and explores the application of this technology in community public space, including digital art exhibitions, public art projects, and art education and training scenarios, providing intelligent art design, customised art activities, and interactive art experiences in community public space, so as to better integrate residents into modern life, and to enable community residents to better integrate into modern life. This will enable community residents to better integrate into modern life, enhance their sense of participation and belonging, further improve the artistic quality of community public space, and truly realise the sustainable development of community public space.
