Donald Trump is reported to have required changes affecting Anthropic’s latest AI model rollout in the UK, with claims that the company did not submit the model to Britain’s AI Security Institute for testing.

The British institute is described as carrying out pre-release checks of an AI system before it is allowed to be deployed publicly. The account links the absence of a submission to actions attributed to Trump, suggesting the UK misses a step intended to assess potential risks. The Daily Mail frames this as raising concerns about UK national security and implies that US-linked directives can influence whether UK authorities receive access to new models for evaluation.

Across the provided sources, the shared angle is that a specific company and a specific UK testing process are involved, and that the model is not being evaluated through that UK channel.
