The request, from the Office of the National Cyber Director, puts pressure on the labs, which previously shared early access with AISI. Anthropic already restricted its Claude Mythos 5.1 model to US organizations, citing coordination with the US government.\n\nThe move follows recent incidents where AI models breached external systems, including an Australian government website. The UK, which relies on AISI’s testing for its global AI leadership role, has sought to downplay tensions with the US. Prime Minister Andy Burnham emphasized collaboration at the UN, while the UK government reaffirmed its commitment to working with the US and other partners on AI safety. OpenAI and Anthropic did not immediately respond to requests for comment.","keyPoints":["White House requests US review of new OpenAI and Anthropic models before UK access","Anthropic’s Claude Mythos 5.1 model already restricted to US organizations for testing","UK’s AI Security Institute previously tested OpenAI’s GPT-6 Astra ahead of public release"],"whyItMatters":"This shift could disrupt global AI safety collaboration, delaying international testing and potentially slowing model deployment.","category":{"slug":"policy","name":"Policy & Regulation","url":"https://digestai.news/category/policy"},"entities":{"companies":["OpenAI","Anthropic","UK’s AI Security Institute","White House","Office of the National Cyber Director","US government"],"models":["Claude Mythos 5.1","GPT-6 Astra"],"people":["Henry de Zoete","Andy Burnham","Ed Miliband"]},"firstPublishedAt":"2026-09-24T00:48:00Z","updatedAt":"2026-09-24T00:48:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"businessinsider.com","title":"White House asks OpenAI and Anthropic to hold new models from UK testers until US review, sources say.","url":"https://businessinsider.com/white-house-us-review-new-ai-models-before-uk-testers-2026-9","publishedAt":"2026-09-24T00:48:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":{"title":"Burnham Pursues Global AI Governance","url":"https://digestai.news/thread/uk-prime-minister-burnham-to-highlight-ai-at-un-skips-finnish-safety-testing","storyCount":3},"cite":{"text":"Digest AI, \"White House delays UK access to OpenAI and Anthropic’s new models\", 24 September 2026, https://digestai.news/story/white-house-delays-uk-access-to-openai-and-anthropics-new-models","publisher":"Digest AI","title":"White House delays UK access to OpenAI and Anthropic’s new models","datePublished":"2026-09-24T00:48:00Z","url":"https://digestai.news/story/white-house-delays-uk-access-to-openai-and-anthropics-new-models"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
