Their work sits where technical expertise meets model safety, bringing in specialists from chemistry, biology, radiation science, nuclear engineering and emergency response to evaluate how AI systems handle high consequence subject matter. The experts on these projects shape how frontier models reason about hazard, risk and public safety, and that reach extends well beyond any single laboratory or response program. They operate remotely across time zones and build their review teams around people who are already practicing in their field. We are helping them identify CBRN specialists for this engagement.
