- Anthropic reported five cases where its AI models were used to support work related to biological weapons, including gain-of-function research on a mosquito-borne virus and experiments to enhance bird flu’s ability to infect mammals, and blocked the accounts due to ambiguous intent.
- OpenAI has implemented guardrails in its models to prevent misuse, but many other AI companies—especially those releasing open-weight models—deploy their systems with far fewer safeguards and little monitoring.
- Harvard and RAND independently published reports this year concluding that AI could expand the number of actors capable of large-scale biological attacks while also enhancing existing state bioweapons programs, though neither confirms the most dangerous thresholds have been crossed.
- The U.S. Select Agent Program prohibits intact genetic material of dangerous pathogens, but shorter DNA fragments that can be reassembled into functional viruses remain unregulated, and a Nature Communications experiment showed 36 of 38 DNA synthesis companies would ship fragments of the 1918 influenza virus.
- DNA synthesis providers operate globally, making it possible to bypass national screening by ordering restricted sequences from another country, undermining any single-nation regulation even if perfectly enforced.
- Ashish K. Jha argues that slowing AI development is only useful if it buys time to build biodefense capabilities, warning that defenses take years to develop and the window to act is closing rapidly.
Why it matters: The erosion of technical and expertise barriers means more actors can now attempt biological weapons development, increasing the likelihood of success through volume alone. Without coordinated global oversight of both AI tools and DNA synthesis, the risk of a pathogen release rises materially—even if individual attempts remain difficult to execute.
