The European Parliament has approved updated rules that require major social media platforms to reveal more about how artificial intelligence systems help moderate user-generated content. The measure is designed to make automated decision-making on speech, posts and account actions more transparent to users and regulators.

Under the new framework, large platforms will need to provide clearer information about where AI is used in content moderation and how those systems influence enforcement decisions. The obligations are expected to take effect next year, giving companies time to adjust their reporting and compliance systems.

Supporters of the legislation say the changes are necessary as AI plays a growing role in filtering online content and shaping what people see. They argue that transparency is essential to ensure accountability, especially when automated tools can affect public debate, access to information and user rights.

The vote adds to a broader push across Europe to set stricter guardrails around artificial intelligence and platform governance. It also reflects rising concern among lawmakers about the hidden role of automated systems in decisions that can remove content or restrict accounts without enough public scrutiny.
