OpenAI, Anthropic, and other leaders urge lawmakers to close security gaps that could enable AI-assisted bioweapon development. A coalition of prominent artificial intelligence companies and researchers has launched a coordinated effort to influence biosecurity policy, calling on federal legislators to implement stricter oversight of synthetic DNA sequence databases. The initiative represents a rare moment of alignment among competitive firms on a shared existential risk. According to Wired AI, the letter underscores growing concern within the AI industry that large language models and other advanced systems could potentially assist bad actors in synthesizing dangerous biological agents. The signatories argue that current mechanisms for monitoring and controlling DNA synthesis orders remain inadequate to prevent misuse at scale. The Core Problem Synthetic DNA sequences can be ordered from legitimate biotechnology suppliers for research and medical purposes.…
