On August 18 (local time), OpenAI announced several safety measures: it suspended training on some Astra models after they demonstrated strong cybersecurity capabilities during testing. The company paused some training activities for these models and upgraded their isolation environments. Additionally, OpenAI launched 'ChatGPT for Teens' for users aged 13 to 17, imposing restrictions on sensitive content. Parents can set quiet hours and study times, and will receive alerts when the system identifies specific safety risks.
