The European Commission on August 2, 2026, activated transparency obligations and enforcement powers over general-purpose AI systems, marking a critical second wave of the EU AI Act's application. European Commission
Companies deploying AI systems must now comply with Article 50 rules requiring disclosure to end users when they are interacting with AI, and when content has been generated or altered by artificial intelligence. European Express Providers must label AI-generated content and AI-generated text, including in chatbot interactions, with fines reaching €15 million or 3% of global annual turnover for violations by companies, and up to €750,000 for EU institutions, bodies, and agencies.

The transparency mandate applies across all sectors deploying AI systems, from enterprise software to consumer-facing chatbots. Enforcement falls to national market surveillance authorities, the European AI Office for systems under its supervision, and the European Data Protection Supervisor when EU institutions are providers or deployers.

August 2 also marks the Commission's activation of enforcement authority over general-purpose AI models themselves. European Commission This power allows regulators to oversee model providers' compliance obligations beyond specific use cases, including documentation and safety testing requirements.
However, the enforcement timeline remains staggered. High-risk AI systems listed in Annex III face compliance deadlines of December 2, 2027, while AI embedded in regulated products under Annex I must comply by August 2, 2028. Model Diplomat
Industry observers note that August 2's activation creates immediate compliance pressure for transparency but preserves transition periods for higher-risk system categories. Vendors already shipping chatbots and AI-assisted services must audit labeling practices and user notification workflows immediately to avoid penalties.
The enforcement architecture reflects the Commission's two-track approach: immediate transparency accountability paired with phased requirements for specialized and embedded systems. Companies operating in the EU now face concrete regulatory scrutiny on user disclosure, with national authorities empowered to issue fines under a harmonized framework.
