ChatGPT Age Prediction Algorithm: OpenAI Now Guesses Your Age to Protect Minors

ChatGPT now knows more than just your questions; it's guessing your age. According to TechCrunch, OpenAI has introduced an 'age prediction' feature designed to identify minors and enforce content constraints automatically. This isn't just a simple ID check—it's an AI algorithm analyzing how you behave.

ChatGPT Age Prediction Algorithm: Behavioral Signals Over IDs

Announced on January 20, 2026, the new system leverages an algorithm that monitors specific 'behavioral and account-level signals.' These include the user's stated age, how long the account has existed, and the times of day the user is most active. If the system flags an account as being under 18, ChatGPT will automatically restrict discussions on sensitive topics like sex and violence.

Strengthening Safety Barriers Amid Mounting Criticism

The move comes after years of heavy criticism regarding AI's impact on children. OpenAI faced backlash last April due to a bug that generated erotica for minors. To balance accuracy, OpenAI is partnering with 'Persona,' an ID verification firm. Users mistakenly designated as underage can re-verify their adult status by submitting a selfie through Persona's system.
