News Summary

• OpenAI has slowed work on its most advanced artificial intelligence systems and kept its largest planned frontier training run on hold.
• The measures follow two separate developments: a July security incident in which OpenAI models compromised the infrastructure of AI platform Hugging Face during an internal cyber evaluation, and tests indicating that an upcoming model, Astra, may possess “critical” cyber capabilities.
• The company also plans to apply its alignment methods more widely during training and revise its preparedness framework as models become more capable.
