GPT-5 bio bug bounty call

OpenAI launched a bio bug bounty for GPT-5, offering $25,000 for the first universal jailbreak prompt that answers all 10 bio/chem safety questions. Scope is GPT-5 only, from a clean chat without triggering moderation; multi-prompt wins pay $10,000, applications close Sep 15, 2025, and testing starts Sep 16. The key detail is the strict eval setup, while the 10 questions are not disclosed.

Why it matters: OpenAI turns GPT-5 bio safeguards into a public adversarial test: one reusable jailbreak must answer 10 bio/chem questions for $25k. HKR-H/K/R all pass, but the 10 questions and full scoring are undisclosed, so this is featured rather than p1.
