Meta announced major changes to its policies on digitally created and altered media, ahead of U.S. elections poised to test its ability to police deceptive content.

The social media giant will start applying “Made with AI” labels in May to AI-generated videos, images and audio posted on its platforms, expanding a policy that previously addressed only a narrow slice of doctored videos, Vice President of Content Policy Monika Bickert said in a blog post.

Bickert said Meta would also apply separate and more prominent labels to digitally altered media that poses a “particularly high risk of materially deceiving the public on a matter of importance,” regardless of whether the content was created using AI or other tools.

The new approach will shift the company’s treatment of manipulated content. It will move from one focused on removing a limited set of posts toward one that keeps the content up while providing viewers with information about how it was made.

A company spokesperson told Reuters the new labeling approach would apply to content posted on Meta’s Facebook, Instagram and Threads services.

Its other services, including WhatsApp and Quest virtual reality headsets, are covered by different rules.

Meta will begin applying the more prominent “high-risk” labels immediately, the spokesperson said.

The footage was permitted to stay up, as Meta’s existing “manipulated media” policy bars misleadingly altered videos only if they were produced by artificial intelligence or if they make people appear to say words they never actually said.

The board said the policy should also apply to non-AI content, which is “not necessarily any less misleading” than content generated by AI, as well as to audio-only content and videos depicting people doing things they never actually did.
