Senate bill would require frontier AI labs to hand government model weights 45 days before release

Sens. Warner, Schatz and Kim introduced the AI Risk Management and Security Act of 2026, requiring developers of certain frontier models to give the government model weights, config files, runtimes and libraries at least 45 days before release. The bill cites labs' own warnings that frontier models can find and exploit unknown vulnerabilities unaided, plus recent security failures at AI labs. It's a proposal, not law, but signals the regulatory direction. Training-time security measures would also become mandatory once labs can access such capabilities post-training.
