OpenAI 构建生物防御盾牌以应对不断升级的生物风险

openai released gpt-rosalind, a frontier reasoning model for biology and drug discovery, in april 2026 and followed with the 'roslind biodefense' initiative the next month to secure biological ecosystems. the action plan focuses on equipping responsible defenders with tools to detect threats sooner and develop countermeasures faster, addressing the security implications of increasingly accessible biological ai. this strategy shifts the security paradigm from restriction to active empowerment, aiming to build societal resilience against pandemics and engineered biological threats. future efforts will focus on establishing the evidence and governance frameworks required for the safe deployment of these powerful biological ai capabilities.
