Article 50 transparency obligations: what actually changes on 2 August 2026
On 2 August 2026, the EU AI Act's first broad obligation for ordinary businesses arrives. It is not the heavy high-risk regime. It is a lighter duty that reaches far more companies: tell people when AI is involved.
While the high-risk obligations were deferred to December 2027, the transparency rules in Article 50 were not. They apply from 2 August 2026, and they catch almost any organisation running a customer-facing chatbot or generating content with AI. If you were waiting for the EU AI Act to affect you, this is usually where it does, first.
This guide covers what Article 50 requires, the watermarking grace period that softens part of it, who is on the hook, and what it pointedly does not demand. For the wider timeline, see the EU AI Act explained.
What Article 50 actually requires
Article 50 sets transparency duties for AI systems that interact with people or produce content. Four obligations matter in practice.
AI interaction disclosure. Systems that interact directly with people, such as chatbots and voice agents, must make clear that users are dealing with AI, unless that is already obvious from the context.
Synthetic content labelling. Providers of systems that generate or manipulate audio, image, video, or text must mark the output, in a machine-readable way, as artificially generated.
Deepfake and content disclosure. Deployers that publish deepfakes, or AI-generated text on matters of public interest, must disclose that the content is artificial.
Emotion recognition notification. Where emotion recognition or biometric categorisation is permitted at all, the people subject to it must be informed.
The watermarking grace period
One part of Article 50 has extra runway. The machine-readable marking obligation under Article 50(2) carries a grace period to 2 December 2026 for content and systems already on the market, giving providers a few extra months to implement watermarking. The disclosure duties themselves still begin on 2 August 2026.
Who Article 50 applies to
Both providers and deployers. Providers build the marking and disclosure capability into their systems, and deployers switch it on and disclose in their own use. The reach is wide: any organisation with a customer chatbot, an AI voice line, or a marketing function generating synthetic images, audio, or video is likely in scope. Like the rest of the Act, it applies extraterritorially, so non-EU companies serving EU users are included.
What Article 50 does not require
This is the part worth underlining, because it prevents over-spend. Article 50 is a transparency duty, not the high-risk regime. A chatbot that owes an AI disclosure does not, by virtue of Article 50, need a conformity assessment, a technical file, or EU database registration. Those belong to the high-risk tier, and only when a system is used in a high-risk context. Confusing the two is the most common way teams inflate a transparency obligation into an imagined high-risk programme. The risk classification guide shows where each system actually lands.
How to comply
Three steps cover most of it. Inventory every user-facing AI system and every AI content workflow you run. Add a clear disclosure wherever AI interacts with people, and labelling or watermarking wherever AI generates content. Then document what you did, so you can show it on request. The compliance checklist folds this into the wider programme.
Why this is the deadline to act on first
Transparency arrives in August 2026, and standalone high-risk obligations not until December 2027. For most organisations that order is a gift: the obligation that lands first is also the lighter one. Treat Article 50 as the near-term task and the high-risk file as the longer build, and you are sequencing the work the way the timeline actually runs.
Frequently asked questions
When do Article 50 obligations apply?
From 2 August 2026. The machine-readable watermarking duty under Article 50(2) has a grace period to 2 December 2026 for content and systems already on the market, but the disclosure obligations begin in August 2026.
Does my chatbot need an AI disclosure?
Yes, if it interacts directly with people and it is not already obvious that they are dealing with AI. The disclosure is the core Article 50 duty for chatbots and voice agents, and it does not turn the chatbot into a high-risk system.
Do I have to label AI-generated content?
Yes. Providers must mark AI-generated or manipulated audio, image, video, and text in a machine-readable way, and deployers must disclose deepfakes and AI-generated content on matters of public interest.
What is the watermarking grace period?
Article 50(2)'s machine-readable marking obligation has until 2 December 2026 to be met for content and systems already on the market, four months after the main Article 50 date.
Does Article 50 apply to companies outside the EU?
Yes. If your AI system interacts with, or produces content for, people in the EU, Article 50 applies regardless of where your company is based.
