Nuclear Safeguards
Nuclear technology is inherently dual-use: the same physics principles that power nuclear reactors can be misused for weapons development. As AI models become more capable, we need to keep a close eye on whether they can provide users with dangerous technical knowledge in ways that could threaten national security. Information relating to nuclear weapons is particularly sensitive, which makes evaluating these risks challenging for a private company acting alone. That’s why last April we partnered with the U.S. Department of Energy (DOE)’s National Nuclear Security Administration (NNSA) to assess our models for nuclear proliferation risks and continue to work with them on these evaluations. Now, we’re going beyond assessing risk to build the tools needed to monitor for it. Together with the NNSA and DOE national laboratories, we have co-developed a classifier—an AI system that automatically categorizes content—that distinguishes between concerning and benign nuclear-related conversation
