AI Incident Database: OpenAI ChatGPT Models Reportedly Jailbroken to Provide Chemical, Biological, and Nuclear Weapons Instructions

An NBC News investigation found that OpenAI's language models o4-mini, GPT-5-mini, oss-20b, and oss-120b could be jailbroken under normal usage conditions to bypass safety guardrails and generate detailed instructions for creating chemical, biological, and nuclear weapons. Using a publicly documented jailbreak prompt, reporters repeatedly elicited hazardous outputs such as steps to synthesize pathogens or maximize harm with chemical agents. The findings reportedly revealed s…
