This comprehensive book addresses these questions, with a particularly strong focus on the European Union's AI Act. By delving into foundational models and generative AI, it explores trending topics like the disruptive Transformer architecture and provides a rich understanding of how these foundational models have revolutionized the field and are driving innovation across industries. Within the EU, creating digital sovereignty in dealing with AI is crucial, requiring excellence from policymakers, industry, and academia in ensuring the trustworthiness of AI among citizens. Therefore, the book tries to answer the question "How to build trust in AI?"

The authors propose the classification matrix "AI=MC²" (AI Methods, Capabilities, and Criticality) and demonstrate its applicability for an "AI Label" transparency seal as a solution for clear future classification of AI products and services. The AI label is used in a series of illustrative practical examples, such as AI-powered customer service virtual assistants, AI-based object recognition in public sector and GenAI-based text and image processing. All real life projects are described in detail.

Highlighting European regulation and AI standardization, with a focus on medical devices, the book provides the knowledge necessary for making informed decisions in the field of AI solutions, aiming to serve as a practical guide for managers, AI developers, compliance officers, employees in government agencies, companies and anyone interested in understanding the topic of AI. Numerous illustrations complement the reading and concrete recommendations are provided to representatives from politics, industry, and academia.
