Our approach to age prediction

Update on August 25, 2026: Age prediction has begun rolling out in the EU, helping us deliver age-appropriate experiences to even more teens around the world.

We’re rolling out age prediction on ChatGPT consumer plans to help determine whether an account likely belongs to someone under 18, so the right experience and safeguards can be applied to teens. As we’ve outlined in our Teen Safety Blueprint⁠ and Under-18 Principles for Model Behavior⁠, young people deserve technology that both expands opportunity and protects their well-being.

Age prediction builds on protections already in place. Teens who tell us they are under 18 when they sign up automatically receive additional safeguards to reduce exposure to sensitive or potentially harmful content. This also enables us to treat adults like adults and use our tools in the way that they want, within the bounds of safety.

We previously shared our early plans⁠ for age prediction, and today we’re sharing more detail as the rollout is underway.

How age prediction works

ChatGPT uses an age prediction model to help estimate whether an account likely belongs to someone under 18. The model looks at a combination of behavioral and account-level signals, including how long an account has existed, typical times of day when someone is active, usage patterns over time, and a user’s stated age. Deploying age prediction helps us learn which signals improve accuracy, and we use those learnings to continuously refine the model over time.

Users who are incorrectly placed in the under-18 experience will always have a fast, simple way to confirm their age and restore their full access with a selfie through Persona, a secure identity-verification service. Users can check if safeguards have been added to their account and start this process at any time by going to Settings > Account.
