Anthropic Developing a New Tool to Detect Concerning AI Talk of Nuclear Weapons

  • Anthropic developed a nuclear threat classifier in partnership with the US Department of Energy’s National Nuclear Security Administration to detect concerning AI conversations.
  • The collaboration began last year to address risks of AI models providing harmful technical knowledge about nuclear weapons, amid rising global concerns.
  • The classifier, designed like a spam filter, scans Claude AI chats in real time and identifies nuclear weapons-related queries with about 95% accuracy.
  • It detected 94.8% of test nuclear queries and had a 5.2% false positive rate, but hierarchical summarization improved labeling of flagged conversations.
  • Anthropic deployed the tool on some Claude traffic and pledged to share insights with the Frontier Model Forum to help others build similar safeguards.
