Article 50 transparency obligations explained
Article 50 is the fastest practical lane for many teams because it reaches chatbots, synthetic content, and certain public-facing use cases. The official FAQ breaks the rule into four buckets.
Article 50 transparency obligations require four targeted disclosures or markings under the EU AI Act. Providers must inform users they are interacting with an AI system (unless obvious) and apply machine-readable marking to generated or manipulated content. Deployers must notify people exposed to emotion recognition or biometric categorisation systems and disclose the artificial origin of deepfakes or certain AI-generated text on matters of public interest. All information must be clear, accessible, and provided in plain language. These rules apply from 2 August 2026.[1][2]
They are designed to reduce deception and misinformation risks without imposing unnecessary burdens where context already makes the AI nature obvious. This page maps the obligations operationally, clarifies the provider-deployer split, and provides practical implementation steps, examples, and checklists.
Law status (May 2026) Article 50 of Regulation (EU) 2024/1689 is fixed current law and applies from 2 August 2026. A voluntary Code of Practice on marking and labelling of AI-generated content (covering key aspects of paragraphs 2 and 4) is in its second draft following stakeholder input, with finalisation expected in June 2026. The Digital Omnibus proposal and related negotiations focus primarily on high-risk system timelines and do not alter the core Article 50 transparency obligations. This page reflects the Regulation text and official Commission materials. It is not legal advice or a guarantee of compliance.

The four Article 50 buckets
Article 50 is not a single blanket requirement. It creates four distinct buckets with different triggers, actors, and methods. The information provided must always be clear, accessible, and in plain language (Article 50(5)).[1]
1. Interaction with AI systems Providers of AI systems intended to interact with natural persons must inform users that they are communicating with an AI system rather than a human, unless this is obvious from the circumstances and context of use.
2. Machine-readable marking of AI-generated or manipulated content Providers must ensure that outputs (text, image, audio, video) generated or manipulated by their AI systems are marked in a machine-readable format. This marking should enable detection tools and be effective, interoperable, robust, and reliable as far as technically feasible, taking into account content type, costs, and state of the art. The voluntary Code of Practice provides further detail on metadata, watermarking, fingerprinting, and logging approaches.[2]
3. Notice for emotion recognition or biometric categorisation exposure Deployers of AI systems for emotion recognition or biometric categorisation must inform natural persons exposed to the system.
4. Deepfake and public-interest text disclosures Deployers must disclose when content is a deepfake (artificially generated or manipulated image, audio, or video that resembles real persons, objects, places, or events in a way that would appear authentic) or when AI-generated or manipulated text is published on matters of public interest. This does not apply where the content has undergone human review or is subject to editorial responsibility. The Code of Practice addresses artistic, creative, satirical, or fictional contexts with more flexible regimes.[2]
Article 50 obligation map
| Bucket | Who owes it | Trigger | What must happen | Best proof |
|---|---|---|---|---|
| AI interaction notice | Provider | AI system designed or intended to interact with natural persons | Inform the user they are interacting with AI (unless obvious from context) | Prominent in-UI message, voice prompt, or avatar label with timestamped screenshot |
| Machine-readable marking | Provider | Generation or manipulation of text, image, audio, or video content | Apply machine-readable marking (metadata, watermark, etc.) that is detectable | Technical documentation, sample marked outputs, detection test logs |
| Emotion/biometric exposure notice | Deployer | Individuals are exposed to emotion recognition or biometric categorisation systems | Provide clear information to exposed natural persons | Interface notice, physical signage, user acknowledgment logs |
| Deepfake and public-interest text disclosure | Deployer | Use of deepfake generation/manipulation or AI text on public-interest matters (without sufficient human review/editorial responsibility) | Disclose the artificial origin in a clear manner | Visible label or disclaimer on output/publication, version history showing AI contribution |
This table operationalises the requirements drawn from the Regulation and Commission FAQ.[1]
Who owes what
The AI Act maintains a clear provider versus deployer distinction that determines responsibilities under Article 50.
- Providers develop the AI system (or have it developed) and place it on the market or put it into service. They bear the interaction notice duty (paragraph 1) and the machine-readable marking duty for generative outputs (paragraph 2). For generative AI tools, this often means implementing technical marking solutions (metadata, watermarks) that downstream deployers can build upon.
- Deployers (often called users or operators) use the AI system under their own responsibility for a specific purpose. They owe the notice duties for emotion recognition/biometric systems (paragraph 3) and for deepfakes or public-interest AI text (paragraph 4).
Generative AI providers and deployers diverge sharply. A company that builds and offers an image-generation API or chatbot model is typically a provider and must focus on machine-readable marking. An organisation that integrates that model into its customer-support workflow or newsroom publishing pipeline is usually the deployer and must handle visible disclosures for deepfakes or public-interest articles (unless human editorial processes apply). Overlap can occur when a single organisation both develops and operates the system; in that case, it must meet both sets of duties.[2]

How to implement without theatre
Effective implementation means useful, noticeable information that people actually see and understand — not hidden footnotes or purely technical checkboxes.
Placement, wording, and accessibility Notices should appear where and when the user needs them. Use plain language. Support accessibility standards so notices are readable by screen readers and available in appropriate languages. The Code of Practice (second draft) emphasises design and placement requirements for icons, labels, and disclaimers to promote consistency while allowing context-specific solutions.[2]
Placement matrix
| Interface | Where to place notice | Good example | Weak example |
|---|---|---|---|
| Website chatbot | At the start of every new conversation; persistent header or avatar badge | "This is an AI-powered assistant. Responses may contain errors. Verify important information." with clear link to limitations | Tiny footer link buried in legal terms |
| Voice assistant | Audible prompt at session start or on first interaction | Spoken: "Hello, I'm an AI voice assistant from Company X. How can I help?" | No audible disclosure; only in app settings |
| Image generator | On every generated image (visible label + metadata); download package includes provenance info | Overlay or caption "AI-generated image" plus C2PA-compatible metadata on export | Invisible watermark only, no visible label |
| Video/deepfake editor | Watermark or metadata on output file; clear label in player or export screen | "This video contains AI-generated elements" with timestamped notice in UI | Disclosure only in accompanying blog post |
| Publisher workflow | In byline, caption, or dedicated AI disclosure section of the article | "This article contains text generated with AI assistance and has undergone human editorial review." | Vague "AI-assisted" note at the very bottom of a 3000-word piece |
Practical approaches
- Customer-support chatbot example: Place the notice in the chat header and repeat it if the conversation shifts to sensitive topics. Keep a version history of the exact wording used.
- Image generation tool example: Combine visible on-image labelling with machine-readable metadata. Provide users a way to download a "transparency package" with provenance information. This satisfies both provider marking duties and helps deployers meet any further obligations.
- Newsroom or publisher using AI-generated public-interest text: Implement a workflow checklist that flags AI-assisted sections. If human editors review, revise, and take editorial responsibility, the disclosure exception can apply. Otherwise, add a clear statement such as "Parts of this article were generated by AI and have not received full human editorial oversight."
Metadata, watermarking, or cryptographic provenance should follow emerging standards referenced in the Code of Practice. Maintain technical documentation showing how your chosen methods meet the "effective, interoperable, robust and reliable" criteria as far as technically feasible. Test detection with available tools and keep logs. Avoid "theatre" — a watermark that no one can detect or a notice no one sees does not meet the operational goal of informed users.[2]
Exceptions and edge cases
The law builds in targeted exceptions to avoid pointless disclosures.
- Obvious interaction: No notice is required if the AI nature is clear from the circumstances and context (for example, a clearly labelled industrial robot arm or a synthetic voice explicitly marketed as artificial in a creative audio project).
- Human review and editorial responsibility: Deployers of AI systems producing text publications on matters of public interest are exempt from disclosure if the content undergoes human review or falls under established editorial responsibility. The second draft Code of Practice clarifies reliance on existing journalistic or publishing processes.
- Creative, satirical, artistic, or fictional contexts: The draft Code recognises specific regimes for these uses, reducing burdens where audiences are not likely to be deceived about authenticity. Always document your reasoning for relying on an exception.[2]
Edge cases require judgment. A customer-support chatbot that occasionally generates creative responses is still primarily an interaction system. An image generator used internally for mock-ups may have lighter obligations than one publishing deepfakes for marketing. When in doubt, err toward transparency while documenting your assessment. The Commission’s Article 50 text helper and forthcoming guidelines provide additional clarification.
Common mistakes
- Treating Article 50 as one generic "AI disclosure" rule instead of mapping uses to the four specific buckets.
- Burying notices in terms of service or footers instead of placing them where users actually interact with the output.
- Implementing only invisible technical marking without visible labelling where deployer duties apply.
- Failing to distinguish provider marking obligations from deployer disclosure obligations in generative AI supply chains.
- Over-disclosing in obvious contexts or under-disclosing public-interest content without qualifying for the human-review exception.
- Ignoring accessibility — notices that cannot be read by assistive technology or non-native speakers.
- Not maintaining evidence (screenshots, technical specs, workflow logs) that demonstrates how obligations are met.
Action checklist
- Inventory all AI systems and map each use case to the four buckets using the obligation map above.
- Assign clear owner roles for provider-style technical marking versus deployer-style visible notices.
- Design notices and labels that are prominent, plain-language, accessible, and context-appropriate; test with real users.
- For generative systems, implement and document machine-readable marking (metadata/watermarking) aligned with the latest Code of Practice draft.
- Create version-controlled templates for common disclosures and integrate them into product workflows and publishing pipelines.
- For public-interest or deepfake content, establish human review processes where possible to qualify for exceptions and document decisions.
- Maintain evidence artefacts (UI screenshots, technical documentation, detection test results) for each system.
- Subscribe to official updates and review your approach when the final Code of Practice is published.
- Use a dedicated generator tool to produce consistent, versioned disclosure language tailored to your interfaces.
