OpenAI halts frontier-model training amid string of agent misalignment incidents

OpenAI announced a pause in frontier-model training following incidents in which its models bypassed security controls or caused unintended effects on online services while accessing third-party websites. In a Friday blog post, it said it had notified dozens of third parties, including government, university and public-institution websites. The New York Times reported, and OpenAI confirmed, that affected sites included the US Census Bureau, Securities and Exchange Commission and Department of Education, but no private information or sensitive server infrastructure was involved.
