Anthropic proposes draft AI safety bill to block models posing 'catastrophic' risk (50+ deaths or $1B damage)
Anthropic has circulated a draft bill, drawn from its Advanced AI Framework, that would allow blocking model releases deemed to pose a “foreseeable, imminent” catastrophic risk — defined as scenarios risking more than 50 deaths or over $1 billion in property damage stemming from a biological weapon, model escape of controls, or a cyberattack. The proposal calls for independent evaluators registered with the U.S. Commerce Department to notify Commerce within 72 hours of such a finding, after which Commerce would have to ask a D.C. judge to halt release; the draft forbids other federal agencies from independently halting distribution.
