Generative Artificial Intelligence Platform Ecosystems

Generative AI platform ecosystems exhibit unique features and dynamics. The platforms employ a novel approach to user interaction, and the complementors' offerings on the supply side of the platform are tightly coupled with a highly dynamic large language model (LLM) operated by the platform owner. We conducted a case study of OpenAI's ChatGPT platform ecosystem to examine the architecture of generative AI platform ecosystems. We identify that the inter-play of platform core and modules (i.e., GPTs) in the platform periphery differs significantly from traditional software plat-forms. We contribute to the literature on digital platform eco-systems by revealing the novel layered modular architecture of this emerging type of platform ecosystem. We also highlight novel opportunities and challenges for platform complement-ors who offer modules in generative AI platform ecosystems.
