  • Editorial Exemption: Documented human review + responsible person
  • Art. 4 AI Literacy: Mandatory since February 2, 2025, employee training
  • Germany: Bundesnetzagentur as market surveillance authority (KI-MIG)
  • Penalties: Up to €35 million or 7% of global annual turnover
  • Switzerland: Not EU member, but must be compliant when AI systems affect EU persons
  • C2PA, IPTC Metadata and Google SynthID as watermarking standards

EU AI Act Compliance becomes mandatory from August 2026and an opportunity for well-positioned companies.

Article 50 Transparency Obligation

Providers of generative AI must ensure that outputs are marked in machine-readable format and recognizable as AI-generated. Deployers of AI systems that generate text "with the purpose of informing the public" must disclose the AI origin.

Editorial Exemption

The December 2025 draft of the Code of Practice distinguishes between fully AI-generated and AI-assisted content. AI-generated text with documented human review and identified responsible person may be exempt from labeling requirements.

Compliance Timeline

Art. 4 AI Literacy: Mandatory since February 2, 2025, meaning all employees involved in AI planning, implementation, or use must be trained. Art. 50: From August 2, 2026. Penalties: Up to 35 million euros or 7 percent of global annual revenue.

FAQ

When does the labeling requirement for AI content under the EU AI Act come into effect?
The transparency rules under Article 50 apply from August 2, 2026. According to the European Commission's official implementation timeline, the rules for high-risk AI under Annex III also take effect on that date, and enforcement at national and EU level begins. The AI literacy obligation under Article 4 has been in force since February 2, 2025.
Do I have to label AI-generated blog articles and texts?
Not necessarily. The disclosure obligation under Article 50(4) applies to deployers for text that informs the public on matters of public interest. It does not apply if the Editorial Exemption is met, meaning when the AI content has undergone a process of human review or editorial control and a natural or legal person holds editorial responsibility. A documented editorial process is therefore the key lever.
What is the difference between provider and deployer obligations in Article 50?
Providers develop the AI system and must mark outputs as artificially generated in a machine-readable format under paragraph 2. Deployers use the system in their own name and must disclose deepfakes and informative AI text under paragraph 4. A company using a tool like ChatGPT for its own texts is a deployer, not a provider.
What are the penalties for violating the AI labeling requirement?
Article 99 provides for a three-tier system: up to 35 million euros or 7 percent of worldwide annual turnover for prohibited practices, up to 15 million euros or 3 percent for violations of other obligations, and up to 7.5 million euros or 1 percent for incorrect information, whichever is higher. Transparency violations under Article 50 typically fall into the middle tier. In the DACH region, there is an additional risk of cease-and-desist letters under unfair competition law.
Does the EU AI Act also apply to companies in Switzerland?
Switzerland is not an EU member state; the AI Act does not apply there directly. However, Swiss companies must comply with the requirements if their AI systems affect persons in the EU or their output is used in the EU. The principle is similar to the market location principle of the GDPR.
How do I reconcile AI content with Google's E-E-A-T and the labeling requirement?
Both requirements point in the same direction. Google's Helpful Content System and E-E-A-T reward genuine human experience, clear accountability, and added value, exactly what the Editorial Exemption demands. The compliant path is AI for research and drafting, human for facts, depth, sources, and responsibility. Mass-generated thin content violates Google's quality logic and makes it harder to invoke the exemption.
What technical standards apply to the labeling of AI content?
For machine-readable marking under paragraph 2, C2PA and Content Credentials, IPTC metadata, and watermarks such as Google SynthID are the relevant standards. This obligation lies primarily with the tool provider. In addition, the EU is working on a Code of Practice on AI-generated content that will clarify detailed questions and is likely to serve as the de facto benchmark for compliance.
