Google will use machine learning to try and tell if a user is under 18

Google will start testing a feature this year that uses machine learning to weed out children trying to access adult content on YouTube. The "machine learning-based age estimation model" will try to predict whether a user is under 18 and, if so, apply appropriate age filter settings to their account. The announcement came amid a flurry of Google child safety announcements as the US Senate considers a bill that would ban pre-teens from social media. YouTube CEO Neal Mohan first mentioned the ML age restriction feature on Tuesday in his letter about the platform's "bets" for the coming year. "We'll use machine learning in 2025 to help us estimate a user's age -- distinguishing between younger viewers and adults -- to help provide the best and most age-appropriate experiences and protections," he wrote.
