What Happened
On August 2, 2026, the EU AI Act entered a new implementation phase: transparency obligations and enforcement powers became applicable. Commission guidance updated August 3 confirms the operative date, distinguishing it from the law’s original entry into force in 2024 and its June 2026 amendment.
Why It Matters
The milestone moves the framework into active oversight of general-purpose AI and practical disclosure obligations for AI systems. It connects earlier legal commitments with authorities able to investigate noncompliance and require corrective action.
Technical Details
The AI Office can request documentation, evaluate general-purpose models, require corrective measures and impose fines. Relevant systems must disclose AI interaction or generated content. Existing generative systems have until December 2 for Article 50(2) marking and detection duties. High-risk requirements retain separate 2027–2028 deadlines.
