How to Comply with EU AI Act Article 50: Complete Guide for 2026

What is Article 50 of the EU AI Act?

Article 50 of Regulation (EU) 2024/1689 establishes transparency obligations for providers and deployers of certain AI systems. Unlike the high-risk classification system (which only applies to specific AI uses), Article 50's transparency obligations apply broadly — to any AI system used in four specific situations.

The obligations take effect from 2 August 2026 for new systems. Systems already on the market before that date have an extended deadline of 2 December 2026 for machine-readable marking requirements (Article 50(2)).

The Four Transparency Obligations

1. Informing People They're Interacting with AI (Article 50(1))

If your AI system interacts directly with people (chatbots, voice assistants, automated phone systems), you must design it so users know they're interacting with AI.

What this means in practice:

• Chatbots must have a persistent "AI Assistant" badge
• Voice systems must announce AI nature at the start of each interaction
• First-message disclosure: "I'm an AI assistant..."

Exception: It's "obvious" to a reasonably well-informed person that they're interacting with AI.

2. Marking AI-Generated Content (Article 50(2))

If your AI system generates synthetic audio, image, video, or text, outputs must be:

• Marked in machine-readable format
• Detectable as artificially generated

Technical standards for this marking are being finalized through the EU Code of Practice.

Doesn't apply to: Assistive functions (grammar correction), systems that don't substantially alter input data.

3. Emotion Recognition & Biometric Categorization (Article 50(3))

Deployers of emotion recognition or biometric categorization systems must inform exposed individuals.

Note: Emotion recognition in workplaces and schools is banned entirely under Article 5 (already in force).

4. Deepfakes & Public Interest Text (Article 50(4))

Deployers must disclose:

• Deepfake image, audio, or video content
• AI-generated text published to inform the public on matters of public interest

Exception for text: If the content has undergone human review with editorial responsibility.

Who Must Comply?

Both providers (those who develop AI systems) and deployers (those who use them) have obligations under Article 50. An organization can be both a provider and a deployer.

Role	Obligations

Provider	Article 50(1) — interaction design, Article 50(2) — content marking
Deployer	Article 50(3) — emotion/biometric disclosure, Article 50(4) — deepfake labeling

Penalties for Non-Compliance

Article 99(4)(g) places Article 50 violations in the €15 million or 3% of global annual turnover fine tier — whichever is higher.
