Deterring American AI Model Theft Act of 2026

This bill establishes a framework to protect American-owned closed-source AI models from unauthorized extraction by foreign entities, particularly those from China and Russia. It requires the Secretary of State to conduct assessments identifying which foreign entities are conducting model extraction attacks or facilitating them through fraudulent account networks, then publish a public list of these actors for up to five years. The legislation authorizes the President to impose economic sanctions on identified entities and their affiliates, while also creating mechanisms for industry coordination and sharing information about threats. Importantly, the bill distinguishes between legitimate AI research conducted under contractual terms and unauthorized extraction attempts that bypass access controls or violate usage agreements.
