AI Act enforcement and transparency requirements begin 2 August 2026

Original title: Commission starts enforcing AI Act rules and new transparency requirements on 2 August

AI-generated summary

Starting 2 August 2026, new EU transparency rules require AI systems to disclose their nature to users. Chatbots and interactive AI must identify themselves as AI, not human. Deepfakes and AI-generated or altered content must be labelled, with machine-readable marks added to enable detection. These rules aim to prevent deception and manipulation while helping users make informed decisions.

From EU AI Act Implementation

On the same date, new transparency rules will start to apply, requiring certain AI systems to tell users when they are interacting with AI and when content has been generated or altered by it.

Under the new rules, chatbots and other interactive AI systems will have to tell users they are dealing with AI, not a human. Deepfakes (images, videos, or audio that have been edited or generated using AI) will have to be labelled. AI-generated or altered content will also have to carry machine-readable marks so it can be detected more easily.

The measures are intended to reduce deception and manipulation and help people make informed choices. They also give businesses clearer obligations and a practical way to show compliance. The Commission published a first list of more than 180 organisations that have signed the Code of Practice on transparency of AI-generated content that operationalises the rules on transparency of AI-generated content.
