Daily Briefing: OpenAI Pays $25K to Break GPT-5.5's Biosafety Guardrails

OpenAI launched a crowdsourced bug bounty program offering $25,000 rewards to security researchers who can demonstrate that GPT-5.5 meaningfully lowers barriers to bioweapon creation. The program runs through July 27, 2026, and represents a notable format choice: treating biosecurity as an ongoing adversarial challenge requiring external pressure-testing with financial incentives, rather than relying solely on internal red-teaming. The episode examines what this format choice reveals about how frontier labs think about dual-use biological risk, and what signals to watch when the testing window closes.
