OpenAI is upping the ante on AI safety by launching a Bio Bug Bounty program specifically for GPT‑5.5. The challenge? Find a single universal jailbreak prompt that can bypass a five-question bio safety test. If you crack it, you could pocket $25,000 plus bragging rights. The company is inviting researchers with backgrounds in AI red teaming, security, or biosecurity to apply for a chance to test the model in a controlled environment. Access is limited to vetted applicants who sign an NDA, and testing runs from late April through July 2026. Partial wins might earn smaller rewards. This isn’t just a bug hunt — it’s a deliberate stress test to see if frontier AI can be tricked into providing dangerous biological information. Applications are rolling starting April 23. Why it matters: As AI models get more powerful, ensuring they can’t be weaponized for bioterrorism is one of the industry’s highest-stakes challenges.
