Summary
The transparency obligations in Article 50 of the AI Act began to apply on August 2, 2026. Providers must disclose when a person interacts directly with an AI system and add machine-readable marks to generated or manipulated content. Deployers must also identify deepfakes, emotion recognition systems, biometric categorization and public-interest publications generated without human review. The Commission published practical guidelines to help companies and authorities interpret the scope of these obligations.
Why it matters
Transparency stops being a voluntary best practice and becomes an operational obligation for any company offering AI services in the European Union. Agencies that publish content, deploy chatbots or automate communications for European clients now need traceability, labeling and verifiable documentation.
Practical implications
- Audit chatbots, synthetic content and automated flows that can reach users in the European Union.
- Add clear notices of AI interaction and keep records of how content is generated, reviewed and published.
- Review vendors and tools to confirm support for machine-readable marks and content labeling.
