The AI Act of the European Union regulates the development and use of AI comprehensively and for all sectors. Companies, as well as NGOs and public authorities, are subject to obligations under the new European regulation, even if they are located outside of the EU.

The book addresses all relevant questions and provides guidance on how to deal with the obligations for providers, deployers and other stakeholders of the AI ecosystem, enabling compliance with the requirements of the AI Act: What is ‘Artificial Intelligence’ in terms of the EU AI Act? Which AI systems and operators are in scope? What general requirements apply to AI systems and general-purpose AI models? Which AI practices are prohibited? How does the risk-based approach of the AI Act work? How do GDPR and AI Act interact? What technical standards can be implemented to comply with the AI Act? Which fines apply in case of infringements? The book will address these questions and many more in order to facilitate the application and implementation of the EU AI Act for stakeholders of all shapes and sizes.
