Narrow state law preemption, conditional on a strong federal framework.
A proposal that fails to satisfy the minimum conditions above must not preempt any state law regulating frontier AI. Even where the minimum conditions are met, any preemption should be tightly limited to the specific federal frontier-governance function Congress has expressly chosen to occupy, such as model-level catastrophic-risk testing, certification, evaluator accreditation, or closely related reporting obligations for covered frontier systems.
Outside that narrow function, federal law should not be read to occupy the field of AI regulation, to displace state law by implication, or to preempt state statutory or common-law claims. Compliance with a federal regime should not itself create immunity, a safe harbor, or a presumption against liability under otherwise applicable state law. Any preemption should be construed narrowly, and any ambiguity should be resolved in favor of preserving state authority outside the specifically occupied federal function.
Outside of areas with a clear national security nexus, namely cybersecurity, CBRNE, and loss of control, states should retain the ability to legislate without federal interference. Unless and until Congress enacts and implements a truly strong federal framework, states should retain full authority to legislate.
