The White House has asked OpenAI and Anthropic to let U.S. agencies review new AI models before sharing them with the U.K.'s AI Safety Institute (AISI). The request came from the Office of the National Cyber Director, forcing both companies to choose between withholding models from AISI and angering the White House.

Anthropic has already complied with the request, making Claude Mythos 5.1 available only to U.S. organizations. AISI is one of the best-equipped government AI testing agencies in the world, with early access to frontier models from top labs.

In a letter to Parliament, AISI Director Henry de Zoete said the agency still has access to frontier models and tested OpenAI's GPT-6 Astra before release. Prime Minister Andy Burnham played down the conflict at the UN General Assembly, calling for 'shared global principles and standards.'

The responsible U.S. agency, the Center for AI Standards and Innovation (CAISI), has its own problems. It has no permanent director and only a few dozen staffers.

The White House has not said what specific models will be reviewed, and the open question remains about how the U.S. will ensure global safety standards. The source says the issue highlights the growing tension between U.S. and U.K. AI governance.
