The European Union's AI Act transparency requirements kicked in on August 2, 2026, forcing chatbots, voice assistants, and other AI systems to tell users they're not human from the very first interaction. The rules, part of Article 50, apply to any provider or deployer whose AI reaches users in the EU, regardless of where the company is based.
What the transparency rules require
Under the new obligations, any AI system that interacts with people — including chatbots, voice assistants, and AI agents — must disclose its machine nature at the start of the conversation. Deepfakes, whether images, audio, or video, must carry a clear label saying they're artificial. The same goes for text published on matters of public interest, unless a human editor has reviewed it and taken responsibility.
Emotion recognition systems and biometric categorization tools must inform every person they're exposed to. Creative or satirical uses of AI get lighter disclosure duties, but the exemption is narrow.
Who has to comply
The rules target professional and commercial use. That means businesses, freelancers, and monetized influencers all have to follow the transparency rules. Personal, non-professional use is excluded. AI trading bots, automated customer support agents, and token projects using AI-generated promotional videos all fall under the disclosure duties.
The European Commission's AI Office and national regulators now have enforcement powers. They can demand documentation, evaluate models, order corrective measures, or pull non-compliant AI systems from the EU market entirely.
Penalties for getting it wrong
Fines for transparency breaches can reach €15 million or 3% of a company's worldwide annual turnover, whichever is higher. For prohibited practices — like deploying a system that manipulates behavior — the ceiling is €35 million or 7% of global annual turnover.
What's still coming
Generative AI systems already on the market have until December 2, 2026, to add machine-readable watermarks to synthetic content. High-risk AI obligations — covering hiring, credit scoring, and law enforcement — were pushed back to December 2, 2027, under the Digital Omnibus amendment signed July 8, 2026. AI embedded in regulated products like medical devices gets until August 2, 2028.
The European Commission's AI Office is expected to publish guidance on how to comply with the transparency rules in the coming weeks. Companies that haven't updated their systems yet face a tight window to avoid penalties.
