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?
