Now, for some news on the lighter side…like 'how to prevent machines from enabling nuclear armageddon"..
In August, Anthropic announced that its chatbot Claude would not — and could not — help anyone build a nuclear weapon. The company said it worked with the Department of Energy (DOE) and the National Nuclear Security Administration (NNSA) to ensure Claude couldn’t leak nuclear secrets, according to a new writeup from Wired.
Anthropic deployed Claude “in a Top Secret environment so that the NNSA could systematically test whether AI models could create or exacerbate nuclear risks,” says Marina Favaro, Anthropic’s head of National Security Policy & Partnerships. Using Amazon’s Top Secret cloud, the agencies “red-teamed” Claude and developed “a sophisticated filter for AI conversations.”
This “nuclear classifier” flags when chats drift toward dangerous territory using an NNSA list of “risk indicators, specific topics, and technical details.” Favaro says it “catches concerning conversations without flagging legitimate discussions about nuclear energy or medical isotopes.”
Wired writes that NNSA official Wendin Smith says AI “has profoundly shifted the national security space” and that the agency’s expertise “places us in a unique position to aid in the deployment of tools that guard against potential risk."
