Among the growing fears about artificial intelligence, one threat has proved particularly alarming: the possibility that A.I. could be used to create a new wave of biological weapons.<\/p>\n\n\n\n
In April, biosecurity experts warned that it was disturbingly easy<\/a> to get advice from chatbots about making pathogens more dangerous. In June, scientists and A.I. executives signed an open letter<\/a> calling for new controls on the fabrication of DNA because A.I. can now speed up the design of toxins and viruses.<\/p>\n\n\n\n In August, scientists reported that they had used A.I. to build viruses<\/a> not seen in nature. And on Thursday, Anthropic announced<\/a> that it had blocked several attempts to use its models by people who might have been trying to weaponize pathogens.<\/p>\n\n\n\n Dario Amodei, the chief executive of Anthropic, followed up with a call<\/a> on Saturday to slow down the development of A.I., with a set of proposals to keep it safe.<\/p>\n\n\n\n Read it all<\/a>.<\/p> A.I. Queries From Abroad Raise Fears of a Biological Weapons Race
Today\u2019s chatbots aren\u2019t likely to help lone actors invent a deadly pathogen, experts say. But newer models, trained in biology, may need stronger safeguardshttps:\/\/t.co\/x3XhW9s4ph<\/a><\/p>— Emily Turrettini (@textually) September 14, 2026<\/a><\/blockquote>
