Question to the Cabinet Office:

To ask the Minister for Cabinet Office, what assessment has the department made of the potential impact of Anthropic's decision not to provide the UK AI Security Institute with pre-release access to its latest frontier AI model on UK AI safety and national security.

The UK's AI Security Institute (AISI) has built trusted, voluntary relationships with the world's leading AI labs. This collaborative approach lets us keep pace with a fast-moving technology and adapt as it evolves and has allowed AISI to secure privileged access that has identified dozens of vulnerabilities that developers fixed before public release. AISI is in daily conversation with industry partners, including Anthropic, and works closely with allies and partners around the world on the risks posed by increasingly capable AI systems. Further detail is provided in Written Statement UIN HCWS314 'Artificial intelligence update'.
