GPT-5.5 Bio Bug Bounty
OpenAI is evolving its GPT-5.5 Bio Bug Bounty into an ongoing private initiative named the OpenAI Bio Bounty Program. The program increases reward amounts and focuses on universal jailbreaks against predefined biosafety challenges in frontier models, beginning with GPT-5.6. Testing for GPT-5.5 concludes on July 27, 2026.
The Core Development
As part of our ongoing efforts to strengthen our safeguards for advanced AI capabilities in biology, we’re evolving our GPT‑5.5 Bio Bug Bounty to become an ongoing private program—the OpenAI Bio Bounty Program. The program will remain focused on universal jailbreaks that can defeat our predefined biosafety challenge against OpenAI’s frontier models, starting with GPT‑5.6 and going forward.
We’re also excited to announce that we’re increasing reward amounts. The reward for a universal jailbreak for the OpenAI Bio Bounty Program has been raised from $25,000 to $50,000 for both GPT‑5.6 and GPT‑5.5. Smaller awards may be granted for partial wins at our discretion.
We will continue to honor the scope for the GPT‑5.5 Bio Bounty Program as originally announced, with testing ending on July 27, 2026. After this date, only GPT‑5.6 will be in scope; we will continue to communicate any future changes in scope to our researchers.
Strategic Perspective & Ecosystem Impact
Interested applicants should apply through our rolling application process (opens in a new window) . Once selected, accepted applicants will be onboarded to the bio bug bounty platform. All past applicants to the GPT‑5.5 Bio Bounty Program will not need to reapply.
Submit a short application here (opens in a new window) (name, affiliation, experience). Accepted applicants must have existing ChatGPT accounts to apply, and will sign a NDA. Apply now and help us make frontier AI safer.

Why it matters
This update highlights how frontier AI developers are formalizing and expanding bug bounty programs specifically targeting biological risks and universal jailbreaks. Increasing financial incentives reflects the growing emphasis on proactive safety testing for advanced models.
