TLDR: The European Commission has initiated a public consultation to establish comprehensive guidelines and a Code of Practice for AI transparency, as mandated by Article 50 of the AI Act. The consultation, open until October 2, 2025, seeks input from a wide range of stakeholders on requirements for interactive AI systems, generative AI content marking, emotion recognition disclosure, and deepfake labeling. These measures aim to enhance trust and clarity regarding AI interactions and content within the EU, with the obligations becoming legally binding from August 2, 2026.
The European Commission’s AI Office officially launched a comprehensive public consultation on September 4, 2025, aimed at developing detailed guidelines and a Code of Practice for ensuring transparency in artificial intelligence systems. This initiative is a direct response to Article 50 of the landmark AI Act, which entered into force on August 1, 2024, and seeks to establish clear standards for AI deployment across European markets.
The consultation period is set for four weeks, concluding on October 2, 2025, at 23:59 CET. It invites a broad spectrum of stakeholders, including AI system providers and deployers, academic institutions, civil society organizations, supervisory authorities, and citizens, to contribute their insights. Concurrently, a call for expressions of interest has been opened, allowing direct participation in the Code of Practice development process.
Key Transparency Obligations Under Article 50:
1. Interactive AI Systems: Providers of interactive AI systems, such as chatbots and virtual assistants, must inform users when they are interacting with AI rather than a human, unless the AI’s nature is ‘obvious’ to a reasonably well-informed observer. This has significant implications for customer service and marketing tools.
2. Generative AI Content Marking: Providers of generative AI systems are required to implement machine-readable marking systems for synthetic content. Proposed technical solutions include ‘watermarks, metadata identifications, cryptographic methods for proving provenance and authenticity of content, logging methods, fingerprints, or a combination of such techniques.’ These solutions must be ‘effective, interoperable, robust and reliable’ while considering implementation costs and the state of the art.
3. Emotion Recognition and Biometric Categorization Systems: Deployers of these systems must notify individuals about their exposure to such technologies. This impacts advertising platforms utilizing facial recognition or emotion detection for audience targeting.
4. Deepfake Content and AI-Manipulated Text: Systems generating deepfake content or AI-manipulated text for public information purposes must disclose their artificial origins, with limited exceptions for artistic works and law enforcement.
Implications for the Marketing Industry:
The new transparency obligations carry substantial implications for digital marketing. Chatbots and virtual assistants will need clear notification mechanisms from the first user interaction. Advertising platforms employing biometric categorization for targeting will require explicit user notification. Furthermore, AI-generated advertising copy, images, videos, and audio content will need machine-readable identification markers, affecting programmatic creative optimization and dynamic ad generation workflows.
Stakeholder Engagement and Enforcement Timeline:
The consultation questionnaire is structured into five sections, covering interactive AI, synthetic content marking, emotion recognition/biometric categorization, deepfake requirements, and horizontal implementation issues. The Commission will publish aggregated results, maintaining respondent anonymity unless consent for public identification is given.
While the AI Act entered into force on August 1, 2024, the transparency obligations under Article 50 will become legally applicable from August 2, 2026. This extended timeline provides organizations with preparation time. The Commission has noted varied industry responses to EU AI regulation, with Meta declining to sign the General-Purpose AI Code of Practice due to concerns about scope, while tech giants like Google, Microsoft, OpenAI, and Anthropic have committed to the voluntary framework. The Commission retains the authority to develop common implementation rules if voluntary codes prove insufficient.
Industry Concerns and Technical Challenges:
Technical implementation poses complex challenges, particularly regarding the effectiveness and interoperability of marking techniques across different content modalities. Cost considerations are also acknowledged, suggesting flexibility for smaller providers. The consultation also aims to coordinate with other EU and national legislation, including data protection regulations.
Timeline Summary:
August 1, 2024: AI Act enters into force.
September 4, 2025: European Commission launches transparency consultation.
October 2, 2025: Consultation deadline and expression of interest closing date.
November 2025: Opening plenary session for Code of Practice participants.
June 2026: Expected completion of Code of Practice drafting process.
