OpenAI Rolls Out AI-Based Age Prediction for ChatGPT to Protect Teen Users

OpenAI deployed age prediction technology for ChatGPT consumer plans on January 20, 2026, using behavioral signals — account age, login patterns, and usage times — to identify users likely under 18 and automatically apply stricter safety settings for content involving violence and self-harm. Users incorrectly flagged as minors can verify their age via Persona, a third-party identity verification service requiring a government ID or live selfie. The move responded to growing legislative and regulatory pressure over AI safety for minors, including calls for mandatory age verification laws.
