AI leaders call for tougher protections against AI-aided bioweapons

Major AI company leaders, including those from Anthropic, OpenAI, and Microsoft, have sent an open letter to US lawmakers calling for stronger rules to prevent their AI systems from being used to develop biological weapons. They argue there is a serious gap in biosecurity (protections against biological threats) that could allow people to use AI to help create dangerous genetic material for harmful purposes, potentially causing a global pandemic.
