OpenAI has doubled the maximum reward under its specialised Bio Bug Bounty Program to $50,000, as the ChatGPT maker looks to strengthen safeguards around its most advanced artificial intelligence models. The highest payout will be awarded to researchers who discover a universal biosafety jailbreak - a prompt or technique that consistently bypasses the model's safety guardrails and enables it to generate restricted biology-related information. The move marks an expansion of a programme that was initially launched as a limited challenge for GPT-5.5, and OpenAI is now turning it into a permanent initiative, with testing beginning on its latest frontier model, GPT-5.6. Unlike traditional bug bounty programmes that focus on software vulnerabilities, the Bio Bug Bounty is designed to uncover weaknesses in an AI model's safety behaviour. Participation is restricted; interested researchers must apply, meet OpenAI's eligibility criteria and sign a non-disclosure agreement before gaining access to the testing environment. The company may also issue smaller rewards for findings that do not fully qualify as universal jailbreaks but still provide useful insights.
