OpenAI paused training of its most advanced AI models over growing cyber safety concerns
OpenAI has temporarily slowed training of its most advanced AI models as it strengthens safeguards around increasingly capable systems.
The company paused reinforcement learning training for two weeks, and its largest planned frontier training run is still on hold.
The move came after a security incident involving OpenAI and Hugging Face, and signs that its upcoming Astra model may have highly advanced cyber capabilities.
OpenAI is now adding stronger monitoring, tighter internet access, safer research environments, and more alignment testing.
Some Astra training and testing remain paused until they meet the new security standards.
