消息，据路透社报道，美国参议院谈判代表正在讨论立法，要求人工智能公司证明其正在采取合理预防措施，以防止工具造成危害。该提案拟赋予美国商务部长权力，要求开发者提供已采取合理步骤防止危害的证明，即“注意义务”，并授权派遣政府审计人员测试相关产品。路透社未能立即确定何为“合理”，相关立法仍在讨论中。即便国会通过该措施，其成为法律的前景仍面临较大阻力。美国总统唐纳德·特朗普周一表示，现有权限已足以监管和起诉科技公司，暗示其不会签署为人工智能设定新规则的法案。参议院多数党领袖约翰·图恩、参议院商务委员会主席特德·克鲁兹以及参与谈判的民主党参议员艾米·克洛布查尔正在讨论该提案。图恩周一告诉记者，国会可以在不损害美国在人工智能竞赛中领先地位的情况下，为更重大威胁设置护栏。克洛布查尔在声明中表示，其正继续推动两党立法，对人工智能模型带来的最大风险进行政府监督，包括要求开发者与政府专家合作验证和测试模型以确保安全。商务委员会资深民主党人玛丽亚·坎特韦尔也参与相关讨论。路透社周五报道，谈判代表还在讨论若政府认定某些人工智能模型不安全并希望阻止其发布，可引入联邦法院，公司可在联邦法院挑战该决定。该措施中涉及联邦法院的部分还将阻止各州执行自身针对人工智能模型特定风险的法律。
