The guidelines from the European Commission come as companies grapple with the complexity and cost of complying with the world s first legislation on the use of the technology, Reuters reported.

The Artificial Intelligence Act, binding since last year, will be fully applicable on Aug. 2, 2026, with certain provisions kicking in earlier, such as the ban on certain practices from Feb. 2 this year.

"The ambition is to provide legal certainty for those who provide or deploy the artificial intelligence systems on the European market, also for the market surveillance authorities. The guidelines are not legally binding," a Commission official told reporters.

Prohibited practices include AI-enabled dark patterns embedded in services designed to manipulate users into making substantial financial commitments, and AI-enabled applications which exploit users based on their age, disability or socio-economic situation.

AI-enabled social scoring using unrelated personal data such as origin and race by social welfare agencies and other public and private bodies is banned, while police are not allowed to predict individuals  criminal behaviour solely based on their biometric data if this has not been verified.

Employers cannot use webcams and voice recognition systems to track employees  emotions, while mobile CCTV cameras equipped with AI-based facial recognition technologies for law enforcement purposes are prohibited, with limited exceptions and stringent safeguards.

EU countries have until Aug. 2 to designate market surveillance authorities to enforce the AI rules. AI breaches can cost companies fines ranging from 1.5% to 7% of their total global revenue.

The EU AI Act is more comprehensive than the United States  light-touch voluntary compliance approach while China s approach aims to maintain social stability and state control.
