OpenAI and Anthropic Sign Letter to Prevent AI-Developed Biological Weapons

Article excerpt

OpenAI, Anthropic, and other major AI labs have signed a letter to lawmakers calling for tighter tracking of synthetic DNA sequences that could be weaponized. The signatories, including executives and scientists, argue that AI tools are making it easier to design dangerous pathogens, and that screening systems for DNA orders need stronger oversight. The letter urges governments to implement better controls before the technology becomes widely accessible. It represents a rare moment of consensus among competing AI companies on a shared regulatory need, though it stops short of proposing specific legislative measures.
