US Lawmakers Tackle Frontier AI Safety with Anthropic's Proposal
Key Summary
Anthropic has presented a draft federal bill to US lawmakers addressing frontier AI safety and security, outlining strict thresholds for government intervention and mandatory independent evaluations. The proposal, influenced by California's SB 53, aims to mitigate catastrophic risks associated with advanced AI models. Key takeaways include the $1 billion damage line and the 50-person casualty line, as well as the creation of a new market for registered third-party testers.
Precedent & Market Context
Anthropic's proposal for a federal bill on frontier AI safety and security draws inspiration from California's SB 53, which was signed into law in 2025. The draft bill, presented to US lawmakers, outlines strict thresholds for government intervention and mandatory independent evaluations of advanced AI models. This move is a response to the growing concerns surrounding the risks associated with highly advanced AI systems.
What the Draft Bill Would Do
The draft sets out strict thresholds for when Washington could act. Intervention would be allowed where potential damages exceed $1 billion, or where AI use could cause the deaths or serious injuries of more than 50 people. The bill ties those thresholds to three specific danger zones: biological weapons, a developer losing control of its own model, and cyberattacks.
Testing is the second pillar. The draft calls for independent testing, more transparency, and ongoing evaluation of advanced models. This requirement would mean new spending for any company building frontier models, as firms would need dedicated safety teams, reporting systems, and relationships with registered evaluators.
The thresholds and risk categories suggest the bill is aimed at the most advanced systems, not the average chatbot startup. The independent evaluation requirement could also create a new market. If the draft became law, registered third-party testers would become a required part of the frontier AI supply chain.
The $1 billion damage line and the 50-person casualty line are both high bars. That keeps the government's emergency power focused on catastrophe, but it also means most AI harms would fall outside the bill's intervention authority. The proposal's focus on mandatory independent evaluations and transparency requirements would mean new spending for any company building frontier models. Firms would likely need dedicated safety teams, reporting systems, and relationships with registered evaluators.
