# Developing nuclear safeguards for AI through public-private partnership

**Type:** Problem & solution

## Summary

AI models are increasingly capable, raising concern that they could provide dangerous nuclear-technical knowledge that threatens national security. Nuclear information is especially difficult for a private company to evaluate alone, motivating a partnership with the U.S. Department of Energy’s National Nuclear Security Administration (NNSA). Together with NNSA and DOE national laboratories, the company co-developed a classifier that distinguishes concerning from benign nuclear-related conversations, achieving 96% accuracy in preliminary testing. The classifier has been deployed on Claude traffic within a broader system for identifying model misuse, and early deployment data suggests it works well on real conversations; the approach will be shared with the Frontier Model Forum as a potential blueprint for similar safeguards developed with NNSA.

## Context

As AI models become more capable, they may provide dangerous technical knowledge related to nuclear weapons and proliferation. The source states that nuclear information is particularly sensitive and difficult for a private company to evaluate alone.

## Approach / What changed

The company partnered with the NNSA and DOE national laboratories to co-develop a classifier that categorizes nuclear-related conversations as concerning or benign. It was deployed on Claude traffic, and the approach will be shared with the Frontier Model Forum.

## Takeaways

- The classifier achieved 96% accuracy in preliminary testing when distinguishing concerning from benign nuclear-related conversations.
- The classifier is deployed on Claude traffic as part of a broader system for identifying model misuse.
- The approach will be shared with the Frontier Model Forum as a possible blueprint for safeguards developed with NNSA.
