Independent pre-release testing of new models works again, and the two countries have agreed not to get in its way.
According to The Decoder and Startup Fortune, the White House reversed an order under which Anthropic, OpenAI and Google DeepMind had not given new models to the UK's AI Security Institute since September 24: the Office of the National Cyber Director wanted a US national security review completed first. The pause lasted 17 days and was lifted on October 11; Startup Fortune writes that during the pause Anthropic restricted British access to the Claude Mythos 5.1 model. The press, citing the Daily Telegraph, also reported the reversal; per Bloomberg, the UK will again be able to evaluate leading models before release. The decision followed pressure from UK minister for SI Kanishka Narayan.
