EU AI Act Transparency Rules Now in Force: Existing Systems Have Until December 2

EU AI Act Article 50 took effect August 2, 2026, requiring machine-readable watermarks on AI-generated content and clear disclosure that users are interacting with AI. New systems must comply now; those launched before August 2 have until December 2. Large providers face a tight retrofit window. Penalties reach €15 million or 3% of global turnover.
