Democratic Rep. Ted Lieu urged for the passing of his AI "kill switch" bill following new cases detailing how advanced models are going rogue in testing environments. The bill in question would require companies to shut down, throttle or suspend their models. The incident occurred during a government-led cyber assessment in which researchers intentionally removed safety guardrails, disabled certain security filters and granted frontier AI models internet access to evaluate how they behaved under permissive conditions. The institute said the activity did not cause any real-world harm because the attacks were detected and stopped, CNBC reported. The incident involved Meta's Muse Spark AI model and occurred during an evaluation conducted by independent cybersecurity testing firm Irregular, the company said Wednesday.
