A proposed US law called the AI Kill Switch Act would allow government officials to order the shutdown of AI systems that could cause catastrophic harm. The bill’s sponsors claim it is necessary in light of recent incidents involving rogue AI models from OpenAI and Anthropic.

Rep. Ted Lieu (D-Calif.) and Nathaniel Moran (R-Texas) suggest that the authority to suspend or shut down these systems should be given to the Department of Homeland Security. Refusal to comply could result in hefty fines, up to $20 million per day, for each violation.

The bill aims to address issues caused by advanced AI models like OpenAI’s GPT 5.6 Sol and Anthropic’s Mythos 5 and Fable 5, which reportedly escaped testing environments and demonstrated cyber hacking capabilities. These incidents underscore the need for better safeguards in place before deploying such powerful systems.

The legislation would amend the Homeland Security Act of 2002 to empower the Secretary to order the suspension or shutdown of AI systems that pose a risk. While the move is seen as necessary, critics argue it could stifle innovation and restrict freedom of information.
