Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, on what date the AI Security Institute's access to frontier AI models developed in the United States was (a) interrupted and (b) restored.

As I outlined in my speech on 12 October, the Government has been working closely with the US government and frontier labs to ensure AISI continues to have access to the most powerful AI models. AISI holds trusted, voluntary relationships with the world's leading AI companies, and continues to have access to frontier models for testing both before and after public release. AISI scientists continue to conduct rigorous evaluations of the latest generation of models, including GPT-6 Astra and Gemini 4 Argon.
