The White House has asked ​OpenAI and Anthropic to hold ‌new models from British testers ​until a US ⁠review, Politico reported on Thursday, citing a person familiar with the matter ‌and a senior US administration official.

The White House ‌wants to take steps ‌to ⁠make sure US systems are ⁠secure before the models are shared with partners, according to the report.

The ​White House, Anthropic ‌and OpenAI did not immediately respond to Reuters requests for comment.

The development comes as ‌the White House weighs cybersecurity ​risks posed by increasingly capable AI models, following a ⁠series of incidents in which AI systems gained unauthorized access ‌to real-world computer systems.

Australian officials disclosed on Wednesday that an OpenAI agent breached a government health data portal in June, gaining unauthorised access ‌to files.

OpenAI and Anthropic also warned ​the United Nations Security Council about the risks posed ⁠by increasingly powerful AI systems, urging ⁠governments to work together to manage the technology.
