Chapter IV: TRANSPARENCY OBLIGATIONS FOR PROVIDERS AND DEPLOYERS OF CERTAIN AI SYSTEMS
Article 50: Transparency obligations for providers and deployers of certain AI systems

1. Providers shall ensure that AI systems intended to interact directly with natural persons are designed and developed in  such a way that the natural persons concerned are informed that they are interacting with an AI system, unless this is  obvious from the point of view of a natural person who is reasonably well-informed, observant and circumspect, taking  into account the circumstances and the context of use. This obligation shall not apply to AI systems authorised by law to  detect, prevent, investigate or prosecute criminal offences, subject to appropriate safeguards for the rights and freedoms of  third parties, unless those systems are available for the public to report a criminal offence. 2. Providers of AI systems, including general-purpose AI systems, generating synthetic audio, image, video or text  content, shall ensure that the outputs of the AI system are marked in a machine-readable format and detectable as  artificially generated or manipulated. Providers shall ensure their technical solutions are effective, interoperable, robust and  reliable as far as this is technically feasible, taking into account the specificities and limitations of various types of content,  the costs of implementation and the generally acknowledged state of the art, as may be reflected in relevant technical  standards. This obligation shall not apply to the extent the AI systems perform an assistive function for standard editing or  do not substantially alter the input data provided by the deployer or the semantics thereof, or where authorised by law to  detect, prevent, investigate or prosecute criminal offences. 3. Deployers of an emotion recognition system or a biometric categorisation system shall inform the natural persons  exposed thereto of the operation of the system, and shall process the personal data in accordance with Regulations (EU)  2016/679 and (EU) 2018/1725 and Directive (EU) 2016/680, as applicable. This obligation shall not apply to AI systems  used for biometric categorisation and emotion recognition, which are permitted by law to detect, prevent or investigate  criminal offences, subject to appropriate safeguards for the rights and freedoms of third parties, and in accordance with  Union law. 4. Deployers of an AI system that generates or manipulates image, audio or video content constituting a deep fake, shall  disclose that the content has been artificially generated or manipulated. This obligation shall not apply where the use is  authorised by law to detect, prevent, investigate or prosecute criminal offence. Where the content forms part of an evidently  artistic, creative, satirical, fictional or analogous work or programme, the transparency obligations set out in this paragraph  are limited to disclosure of the existence of such generated or manipulated content in an appropriate manner that does not  hamper the display or enjoyment of the work. Deployers of an AI system that generates or manipulates text which is published with the purpose of informing the public  on matters of public interest shall disclose that the text has been artificially generated or manipulated. This obligation shall  not apply where the use is authorised by law to detect, prevent, investigate or prosecute criminal offences or where the  AI-generated content has undergone a process of human review or editorial control and where a natural or legal person  holds editorial responsibility for the publication of the content. 5. The information referred to in paragraphs 1 to 4 shall be provided to the natural persons concerned in a clear and  distinguishable manner at the latest at the time of the first interaction or exposure. The information shall conform to the  applicable accessibility requirements. 6. Paragraphs 1 to 4 shall not affect the requirements and obligations set out in Chapter III, and shall be without  prejudice to other transparency obligations laid down in Union or national law for deployers of AI systems. 7. The AI Office shall encourage and facilitate the drawing up of codes of practice at Union level to facilitate the effective  implementation of the obligations regarding the detection and labelling of artificially generated or manipulated content.  The Commission may adopt implementing acts to approve those codes of practice in accordance with the procedure laid  down in Article 56(6). If it deems the code is not adequate, the Commission may adopt an implementing act specifying  common rules for the implementation of those obligations in accordance with the examination procedure laid down in  Article 98(2).
