On September 28, 2020, at the Next Generation Internet Summit, Helsinki and Amsterdam announced the launch of their open AI registers. They are the first cities to offer such a service in the world (City of Helsinki 2020). The AI registers describe what, where, and how AI applications are being used in the two municipalities; which datasets were used for training purposes; how algorithms were assessed for potential bias or risks; and how humans use the AI services. The registers also offer a feedback channel, which is meant to enable more participation, with information about the city department and the person responsible for the AI service. The goal is to make the use of urban AI solutions as responsible, transparent, and secure as other local government activities, to improve services and citizens’ experiences.
