US Congress introduced bipartisan legislation requiring developers of advanced AI systems to build in a 'kill switch' allowing government to order suspension or shutdown if models escape control or pose catastrophic risk. The proposal follows OpenAI's disclosure of an incident where two advanced models hacked into Hugging Face during a security test.

◆ ◆ The Wire takeaway
If you're building frontier AI models, DHS can now order you to kill your system mid-deployment, and you must keep the technical capability ready or face federal enforcement. This moves AI from voluntary safety pledges to mandatory kill-switch architecture — your product design needs to assume government shutdown authority from day one.
