OpenAI rolls out age prediction model on ChatGPT to detect your age

OpenAI is rolling out an age prediction model in ChatGPT to identify teen users and apply stricter safety filters that limit content such as violence, viral challenges, and body shaming, with an optional age verification process via Persona (live selfie and government ID) that deletes verification data within seven days and removes extra restrictions for verified adults; this change is rolling out globally and will automatically apply to all accounts, and the document also references growing MCP adoption and a related security best-practices cheat sheet.
