Artificial intelligence (AI) expands the more-than-human perspective on creativity and creative geographies, as new techno-material relations and spatialities are formed when humans and AI create together. In this paper, we suggest the concept of “co-creative spatiality” to refer to the special sites, relations, and processes of human–AI collaboration in artistic creative practice. Our study builds on interviews with 26 Finland-based artists who have used AI in their artistic work. In our analysis, we focus on the questions of what, how, where, who, and with of creativity, through which we study the spatialities of creativity and their links to AI. We discuss, how the emerging techno-materialities of AI affect co-creative spatiality by stretching the boundaries of (human) imagination and sparking creativity across new imaginative terrains. Co-creative spatiality reveals novel and unfamiliar collaborations that constitute our material worlds and, therefore, we believe it invites geographical analysis from all those interested in the transformations of creative and artistic practices in the age of AI.
