The EU's AI Transparency Rules Are Now Live — Here's What Has to Be Disclosed
Since August 2, interactive AI systems must say they're AI, and AI-generated audio, images and video need machine-readable marks. Fines run up to 15 million euros or 3% of global turnover.

AIThe short answer
- Article 50 transparency obligations under the EU AI Act took effect August 2, 2026, covering chatbots, synthetic media, biometric systems and deepfakes.
- The rules apply globally to any provider whose AI systems reach the EU market or whose outputs are used within the EU — not just EU-based companies.
- Violations can trigger fines of up to 15 million euros or 3% of worldwide annual turnover, whichever is higher.
- Existing generative AI systems get until December 2, 2026 to add machine-readable marking and detection tools; content published before August 2 doesn't need retroactive labeling.
A new set of EU AI Act transparency rules became enforceable on August 2, 2026. They don't touch how AI models are built, but they do set rules for what AI systems and their outputs have to disclose to the people encountering them — and the rules reach well past companies headquartered in Europe.
The four things now required
- Interactive AI systems — chatbots, voice assistants — must tell users they're dealing with AI, not a human
- AI-generated or AI-edited audio, images, video and text must carry machine-readable marks and a way to detect them
- Systems using emotion recognition or biometric categorization must inform the people they're assessing
- Deepfakes and AI-altered public content must be disclosed as such, unless the content received substantive human editorial review
Who actually has to comply
The obligations apply to providers and deployers of in-scope AI systems anywhere in the world, as long as the system is placed on the EU market or its output is used within the EU. A company with no European office can still be in scope if EU users interact with its chatbot or see its AI-generated content.
Penalties and the deadlines that matter
Non-compliance can bring fines of up to 15 million euros or 3% of a company's worldwide annual turnover, whichever is higher. Existing generative AI systems have until December 2, 2026 to add the required marking and detection mechanisms; content published before August 2, 2026 does not need to be labeled retroactively. Companies can also sign the EU's voluntary Code of Practice on AI-generated content — more than 180 organizations already have — as a path to demonstrating compliance.
