OpenAI has launched a Bio Bug Bounty program aimed at enhancing the safety of its latest AI model, GPT-5.5. The program, which opened for applications on April 23, 2026, offers a $25,000 reward to the first researcher who can successfully create a universal jailbreak prompt that allows the model to answer five specific biosafety questions without triggering moderation responses. This initiative is significant as it marks one of the first instances where a major AI company is actively seeking external expertise to stress-test its systems. The challenge requires participants to start from a clean chat session, ensuring no prior context influences the model's responses. Applications will be accepted until June 22, 2026, and testing will occur from April 28 to July 27. Only a select group of vetted biosecurity experts and experienced researchers will be invited to participate. All findings will be subject to a non-disclosure agreement, preventing public disclosure of results, which is standard in security research. This move aligns with a broader trend in the AI industry towards structured adversarial testing, enhancing safety protocols.
