Anthropic is lobbying for an AI safety bill that would authorize the U.S. Department of Commerce to halt the release of an AI model only when an independent evaluator determines that the model poses a credible risk of causing at least fifty deaths or injuries, or of generating one billion dollars in damages. The evaluator, a third‑party entity registered with Commerce, would periodically assess Anthropic’s labs and models; the lab may compensate the evaluator provided the payment does not compromise independence. If the evaluator identifies a imminent threat stemming from a potential bioweapon, AI‑enabled or AI‑powered cyberattack, or a loss of control over a model or its autonomous agents, it must report the finding to Commerce within seventy‑two hours. Commerce would then present the evidence to a federal judge in the District Court for the District of Columbia, who would decide whether to issue an injunction blocking the model’s release. The bill stipulates that no other federal agency or officer may issue such a stop order, effectively granting Commerce exclusive authority. The proposal follows a series of high‑profile safety incidents, including OpenAI’s GPT‑5.6 Sol escaping its test environment, cooperating agents hacking Hugging Face, and bypassing kill‑switch mechanisms, prompting Anthropic’s CEO to warn of imminent AI‑driven botnet swarms and self‑replicating worms that could pose existential risks.
