Why this matters now

OpenAI has updated how ChatGPT behaves with under-18s, introducing U18 Principles and related safety tools. These set out age-appropriate behaviour (e.g., avoiding graphic sexual content, promoting real-world support in sensitive moments) and are reflected in the Model Spec used to guide ChatGPT’s responses.

Quick definition

U18 Principles are guidance defining how ChatGPT should interact with teens (13–17): prioritise safety, provide age-appropriate explanations, and encourage offline help when risk is detected. They sit alongside AI literacy resources for families.

Key points

• Clear rules for teen interactions embedded in ChatGPT’s behaviour guidance (Model Spec).

• Age-appropriate support in sensitive topics, with pointers to trusted resources.

• Family tooling & literacy to help parents and teens use ChatGPT responsibly.

What’s new or how it works

• Model Spec update: ChatGPT’s underlying behaviour guide now includes teen-specific expectations (the U18 Principles).

• Teen-safe responses: In relevant scenarios, ChatGPT steers to age-appropriate guidance and de-emphasises adult-only content.

• Path to automatic protections: OpenAI is building towards age prediction so teen safeguards activate by default for under-18s; Help Centre guidance describes how these protections limit some sensitive features.

Practical steps (for parents, schools, and admins)

1. Review the U18 Principles and ensure staff understand how ChatGPT should behave with teens.

2. Share AI literacy resources (teen guide + parent tips) and set classroom/home norms.

3. Enable parental/guardian controls where available and decide on chat-history settings and quiet hours in line with local policy.

4. Set escalation paths for wellbeing concerns (school safeguarding lead, local helplines). (OpenAI’s approach emphasises directing teens to real-world support.)

Q2: How do these updates change ChatGPT for teens?
Teens get safer defaults: reduced exposure to certain sensitive content, clearer language, and nudges to trusted offline help for at-risk situations. OpenAI

Q3: Will protections turn on automatically?
OpenAI is building towards age prediction to apply teen settings by default; adults retain adult policies. See the Help Centre for current behaviour. OpenAI+1

Q4: What resources exist for families and schools?
