Why it matters
OpenAI's Bio Bounty Program signals that universal jailbreaks capable of bypassing biosafety guardrails on frontier LLMs remain a live risk that vendors are paying to surface, relevant to defenders tracking the resilience of deployed AI safety controls.
OpenAI announced its Bio Bounty Program (evolving from the GPT-5.5 Bio Bug Bounty), a private bounty inviting researchers to find universal jailbreaks that defeat the biosafety safeguards on frontier models GPT-5.5 and GPT-5.6. Rewards for a universal jailbreak were raised from $25,000 to $50,000, with smaller awards for partial wins.
