OpenAI has introduced "Age Predictions" in ChatGPT for EU users, which assesses account-level factors to estimate a user's age and restrict access to sensitive content for those identified as under 18. The feature uses various indicators, including stated age and usage patterns, to enhance user safety. If a user is mistakenly restricted, they can undergo an age verification process via a service called Persona. OpenAI is also implementing additional parental controls for managing teen accounts, such as setting "quiet hours" and monitoring AI retention of information. Furthermore, OpenAI plans to launch a ChatGPT Go subscription tier in the U.S. with higher usage limits and will introduce advertisements within ChatGPT conversations, ensuring that user conversations are not used for ad targeting.
