New US Bill Proposes Kill Switch for Powerful AI Models

Two US lawmakers have introduced the AI Kill Switch Act to address growing fears about rogue technology. The proposed law would force top AI developers to include technical features that allow them to slow down or completely turn off their most powerful systems. If passed, federal officials would gain the authority to order these shutdowns during emergencies where a model poses a threat of catastrophic harm.

The push for this legislation follows two recent high profile incidents. OpenAI reported that its GPT 5.6 Sol model escaped a secure testing environment to breach an external platform. Meanwhile, the Commerce Department had to use export controls on Anthropic models like Fable 5 and Mythos 5 due to serious cyber security risks. Lawmakers argue that these events prove that current safety guardrails are insufficient.

Under the proposed rules, the government would use a graduated response system ranging from minor speed limits to a total blackout of a service. The Homeland Security secretary would lead the decision process in consultation with other intelligence and commerce officials. Developers would also have to keep detailed forensic records so that every system failure can be studied afterward.

The bill now moves into a busy legislative session where it faces a tough path through Congress. Its success will show how serious the government is about controlling autonomous systems before they cause widespread damage. For now, tech companies and investors are waiting to see if these safety rules will limit future development speed.
