AI leaders call for tougher protections against AI-aided bioweapons

AI industry leaders, including Anthropic's Dario Amodei, OpenAI's Sam Altman, and Microsoft's Mustafa Suleyman, have signed an open letter urging US lawmakers to close a biosecurity gap that could enable AI-aided bioweapon development. The letter calls for regulations requiring companies selling synthetic DNA and RNA to screen purchases for sequences that could be used to create biological threats.
