European Commission Publishes Guidelines on AI Transparency Rules
The European Commission published guidelines on the AI Act's Article 50 transparency obligations, effective 2 August 2026.
What was published
The European Commission has published guidelines to assist providers and deployers of artificial intelligence systems in meeting the AI Act's transparency obligations. The guidelines were published on 20 July 2026, and they define the scope of the transparency obligations set out in Article 50 of the AI Act. The Commission adopted the guidelines to offer practical guidance to competent authorities, as well as to the providers and deployers who must follow the rules.
Why Article 50 exists
The AI Act follows a risk-based approach, classifying AI systems into four different risk categories. One of those categories covers AI systems that pose transparency risks, and those systems are subject to the obligations laid down in Article 50 of the AI Act. The Commission's stated aim with these new guidelines is to ensure compliance with the transparency obligations in a consistent, effective, proportionate, and uniform manner across the providers and deployers the rules cover.
When the obligations apply
The transparency obligations under Article 50 apply from 2 August 2026. The guidelines themselves were published on 20 July 2026, roughly two weeks ahead of that date, giving providers and deployers of AI systems a window to review the guidance before the obligations take effect.
Who has to pay attention
The guidelines are aimed at two audiences at once. Competent authorities, the bodies responsible for checking compliance, get practical guidance on how to apply Article 50 consistently. Providers, meaning the organizations that build AI systems falling under the transparency-risk category, and deployers, meaning the organizations that put those systems to use, both get direction on what the transparency obligations expect of them. The Commission's own framing is that this guidance should make enforcement consistent, effective, proportionate, and uniform, which suggests the Commission is trying to avoid a patchwork of differing interpretations across the providers and deployers the AI Act covers.
What else the Commission released alongside the guidelines
Beyond the core guidelines document, the Commission also published a set of companion materials. These include an overview of the guidelines on transparency of AI-generated content, a questions-and-answers document on the Article 50 transparency obligations, a fact page summarizing the transparency rules for AI systems, and the Code of Practice on Transparency of AI-Generated Content. The Commission also published a communication approving the content of the guidelines, alongside the main guidelines document on implementing the transparency obligations for certain AI systems under Article 50.
