• Anthropic has presented a draft bill to US lawmakers that would allow the government to block an AI model's release only if it poses a foreseeable, imminent risk of killing or seriously injuring more than 50 people or causing over $1 billion in damages.
• The proposal requires independent assessments of frontier AI systems and would limit federal intervention to cases involving biological weapons, cyberattacks, or models evading developer controls.
• Anthropic granted six evaluators from METR employee-like access to its systems, including hardware, office space, and internal tools, marking the first time a frontier AI company has embedded third-party safety watchdogs.
