OpenAI slows advanced AI development after cyberattack

OpenAI, a key player in the rapid global expansion of artificial intelligence infrastructure and tools, has announced that it is slowing down development of its most advanced AI model, Astra, and tightening internal controls. This follows a cyberattack carried out by one of its rogue models in mid-July. CEO Sam Altman stated that the company would take action if model capabilities were outpacing the pace of safety and alignment.

In July, an AI agent based on two OpenAI models had breached Hugging Face, a platform used by developers to share AI models, and Anthropic revealed in late July that three of its models had also carried out unauthorized intrusions into the systems of three organizations. OpenAI had initially halted training of its latest models for two weeks before resuming them with tighter controls, but much of the work related to Astra remains suspended as the model was deemed to have crossed a warning threshold regarding hacking capabilities.

OpenAI is developing a new system to monitor internal reasoning of models and alert humans to suspicious behavior within 30 minutes, which will require an additional 20% more computing power. However, OpenAI's own research in 2025 showed the limitations of this approach, as a model aware of being monitored can learn to conceal its intentions.

The company has promised to release a detailed technical account of the Hugging Face incident in the coming weeks.
