This course introduces students to the study and design of AI agents and digital platforms as contemporary socio-technical systems. Organized into three modules, the course first examines how digital platforms and artificial intelligence have emerged within modern economies and organizations. Students explore how platforms operate through governance structures, organizational infrastructures, and economic processes. The second module introduces different types of AI models, including rule-based systems, machine learning, and large language models, and examines how autonomous agents function within platforms such as marketplaces, media systems, and logistics networks. The final module focuses on hands-on design and prototyping. Students work with existing tools to design a simple AI agent or an agent–platform configuration in a defined real-world context. No prior coding experience is required. The course includes an introduction to basic Python skills sufficient to operate agent-building tools and configure agent behavior.
