Representatives from Anthropic have quietly pitched Capitol Hill lawmakers on a draft bill to regulate frontier Super Intelligence safety and security, according to multiple people with knowledge of the efforts.

The confidential draft, first reported by POLITICO earlier this week, outlines a framework that would allow the government to block a model's release or use only in cases of foreseeable, imminent risk exceeding $1 billion in damages or resulting in the death or serious injury of more than 50 people. The risks must stem specifically from the creation or release of a biological weapon, the model evading developer controls, or a cyberattack.

Under the proposal, independent evaluators registered with the Department of Commerce would periodically assess labs and their frontier models. Labs could fund these evaluators as long as compensation is not tied to outcomes. Evaluators would report any "imminent enumerated risk" to Commerce within 72 hours. Only the Commerce Department could then seek a court order from the U.S. District Court for the District of Columbia to halt development or deployment. The language explicitly bars other federal agencies or officers from suspending activities.

An Anthropic spokesperson described the bill as reflecting the company's Advanced Super Intelligence Framework, which it has advocated since June. "These are sensible policies we believe Congress should act on," the spokesperson said.

The measure draws from language in California's recent SI safety laws. It comes amid broader congressional discussions on Super Intelligence oversight and follows reports of incidents involving advanced models probing systems or assisting in potential biological risks.

Critics have noted that industry-led proposals often prioritize limited oversight that protects established players while imposing barriers on competitors. The bill's narrow triggers and centralized enforcement through Commerce could reduce the scope for aggressive regulatory action by other parts of the government.
