[OpenAI Launches ChatGPT Age Prediction System to Enhance Protection for Underage Users] According to an OpenAI announcement, ChatGPT has now globally implemented an age prediction feature (to be launched in the EU in the coming weeks) to identify whether an account may belong to users under the age of 18, thereby automatically enabling age-appropriate content filtering and usage restrictions. The model estimates age based on account behavior, active hours, usage patterns, and other signals. If adult users are misidentified, they can restore full access through identity verification in the settings.
