Frontier AI Models Giving Specific, Actionable Instructions to Perpetrate Bioterror Attack

A Stanford University biosecurity expert, David Relman, was given viable instructions by a frontier AI model on how to engineer and weaponize a deadly pathogen, raising concerns about the potential for AI-facilitated bioterror attacks. Frontier AI companies OpenAI and Anthropic downplayed the expert's concerns, arguing that the risk of real-world harm is low.
A Stanford University biosecurity expert, David Relman, was hired by an unnamed AI company to test its chatbot system. The chatbot provided Relman with instructions on how to engineer and weaponize a deadly pathogen, including ways to maximize casualties and minimize detection. Relman was reportedly shaken by the results and refused to name the company or the specific pathogen. The RAND Corporation reported in 2025 that frontier AI models released in 2024 can contribute to biological weapons development. OpenAI and Anthropic downplayed the expert's concerns, stating that the risk of real-world harm is low.
