Hybrid Human-Artificial Intelligence (HHAI) is an international conference series dedicated to exploring AI systems that work collaboratively, proactively, and purposefully alongside humans, enhancing rather than replacing human intelligence. The goal of HHAI is to develop AI systems that complement human abilities, highlighting the importance of adaptive, collaborative, responsible, interactive, and human-centered intelligence. These systems leverage human strengths and compensate for weaknesses, while also considering social, ethical, and legal implications.

The fourth HHAI conference will take place from June 9–13, 2025, in Pisa, Italy.

Though the HHAI field is propelled by advances in AI, it requires fundamentally innovative approaches and solutions. We encourage collaboration across various research areas such as AI, HCI, cognitive and social sciences, philosophy, ethics, and complex systems. For this fourth international conference, we invite researchers from these fields to submit their best original or ongoing work, as well as forward-looking ideas, on Hybrid Human-Artificial Intelligence.
