…unless:
- AI Act scope exclusion is used exclusively for military, defence or national-security purposes or developed and used solely for scientific research and development
- Art. 2(3): the Regulation 'does not apply to AI systems where and in so far as they are placed on the market, put into service, or used with or without modification exclusively for military, defence or national security purposes'. (AI Act Art. 2(3))
- Art. 2(6): the Regulation 'does not apply to AI systems or AI models, including their output, specifically developed and put into service for the sole purpose of scientific research and development'. (AI Act Art. 2(6))
- Each Art. 50 transparency duty is disapplied for 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 — except, for Art. (AI Act Art. 50(1), (2), (3) and (4))
- Art. 50(4): the duty does not apply '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'.

Scope in the source's own terms

- Art. 26(1), read with Art. 3(4): the actor is a 'deployer' — a natural or legal person using an AI system under its authority, other than in the course of a personal non-professional activity
- Art. 50(4), second subparagraph: the triggering feature is AI-generated or AI-manipulated TEXT 'published with the purpose of informing the public on matters of public interest'

Sample acceptance criteria Landfall generates for this obligation:
- Publication surfaces carrying public-interest text are identified, and AI-generated or AI-manipulated items on them are flagged at publication
- Each flagged item either carries the disclosure or records BOTH limbs of the exemption: the human review performed, and the person or entity holding editorial responsibility
- Editorial responsibility is recorded as a named person or legal entity, not as a team or a role placeholder
- There is no unlabelled default: publishing AI-generated public-interest text without a disclosure or a recorded exemption is refused
- The disclosure is visible on every surface the item appears on, including syndication and feeds
Evidence an auditor expects

Disclosure on published AI-generated text on matters of public interest
Copies of the published text showing the disclosure that it has been artificially generated or manipulated, presented at the latest at the time of first exposure and in a clear and distinguishable manner (Art. 50(5))
- Process recordDocument review
Editorial review record where the Art. 50(4) editorial exception is relied on
Per-item record showing the human review or editorial control actually performed AND naming the natural or legal person who holds editorial responsibility for the publication. Both limbs are cumulative — a review with no accountable publisher does not engage the exception
