Starting December 16, Meta will leverage user interactions with its AI assistants to tailor content on Facebook, Instagram, and other platforms. Announced on October 3, the update, which affects over 1 billion monthly Meta AI users, will enhance recommendations based on chat topics—like hiking. Notably, Meta assures that sensitive subjects such as health or politics will not influence ad targeting. The rollout excludes the UK, EU, and South Korea, prompting concerns over user transparency.
