Abstract: With the rapid development of artificial intelligence, new concepts of intelligent literature and art have emerged——"intelligent literature + cross-border literature and art", which came into being based on the cross-border integration of literature and art and artificial intelligence. These new paradigms of cross-border creativity have rewritten the theory that "literature is the science of humans", and become a new trend in the development of literature and art in the future. At present, the difficulty of the cross-border development lies in how to solve the complex puzzles of quantum thinking, accidental exceptions, strange circle paradox and so on, which urgently needs the joint thinking and improvement of human and artificial intelligence. The cross-border research of artificial intelligence and literature and art will become a new discipline, but meanwhile there will be many new problems facing it: how to predict the boundaries, risks and future of intelligent literature and art, how to deal with the new phenomena such as immersion, interaction and customization of literature and art, and how to expand the new discourse theory system. The endless problems will bring higher challenges.
