White House restores UK AI Security Institute's access to frontier models
The White House has reversed a prior decision and restored the UK AI Security Institute's (AISI) ability to get early access to models from Anthropic, Google DeepMind, and OpenAI. The reversal follows a September directive that had stopped companies sharing models with AISI and a subsequent restriction on Anthropic's Claude Mythos 5.1; UK AI Minister Kanishka Narayan pushed diplomatically and plans to announce tighter reporting requirements for AI-related security incidents.
