Article 5 covers certain unacceptable AI practices. These require a specific legal review before a system is developed or deployed.
AIACT Research · Updated September 2026
EU AI Act
The EU AI Act is a horizontal, risk-based regulatory framework for artificial intelligence. In 2026, prohibited practices, transparency rules and GPAI obligations are enforceable, while important high-risk-system dates arrive later.
High-risk AI
Article 6 routes include regulated products and sensitive Annex III use cases. The intended purpose of the system is central to classification.
Transparency
Article 50 includes disclosure and marking duties for certain interactive and synthetic-content systems.
GPAI
Providers of general-purpose AI models face documentation, copyright and training-content transparency obligations, with additional duties for systemic-risk models.
