# OpenAI’s next security sprint adds Cathedral and larger bounties

> OpenAI’s next internal security sprint pairs with Cathedral. A critical finding in a core product such as ChatGPT, Codex, or the API Platform can earn up to $30,000, and exceptional critical findings on those targets remain eligible for up to $100,000, or up to $172,000 with bonuses.

OpenAI said on November 2, 2026 that it is planning its next internal security sprint and will partner with Cathedral so outside researchers can use OpenAI’s models, alongside OpenAI teams, to challenge the company’s defenses. A companion post the same day raised Security Bug Bounty payouts: a critical finding in a core product such as ChatGPT, Codex, or the API Platform can now earn up to $30,000, and exceptional critical findings on those targets remain eligible for up to $100,000, or up to $172,000 with bonuses.

The sprint post is a plan, not a results report. It does not give a start date, a duration, or a scope. OpenAI says the exercise will bring new researchers and security partners together with its own teams to use its models to test and strengthen its systems, with Cathedral researchers bringing differentiated expertise to finding weaknesses.

OpenAI’s official account posted on November 3 that the partner is Cathedral Systems. In the company post, Gavin Kliger, CEO and co-founder of Cathedral, said OpenAI is “setting an important example by partnering with outside security firms and using its own models to continuously test and strengthen its defenses,” and that the work would combine OpenAI’s models and security expertise with Cathedral’s research “to find weaknesses, test fixes and strengthen this approach to continuous defense.”

OpenAI points to its last sprint without publishing new vulnerability counts. It dedicated 25% of product engineers to finding and fixing weaknesses. Using Codex, those engineers investigated findings, reproduced vulnerabilities in isolated environments, and prepared patches for review.

## What the new ranges pay

The sprint note says OpenAI is more than quadrupling rewards for critical findings. The bounty post is more precise: OpenAI is more than quadrupling the midpoint of reward ranges for medium, high, and critical findings on average, and adding incentives for higher-quality reports.

High-quality reports can earn a bonus multiplier when a reliable proof of concept isolates the bug, shows when it can be exploited, and demonstrates its impact. A five-tier loyalty program adds scaling bonuses for researchers who keep working with OpenAI. Priority campaigns will offer dedicated bonus pools for newly launched features.

OpenAI labels its payout table illustrative. One critical ChatGPT row, a one-click account takeover, moves from an illustrative historical award of $6,500 to a calculated $51,577: a $30,000 base times a 1.15 quality bonus, a 1.30 priority-campaign bonus, and a 1.15 “31337” loyalty-tier bonus. An exceptional row—a significant compromise of a security boundary, such as viewing arbitrary ChatGPT users’ chat messages—starts from $100,000 and, with the same example multipliers, calculates to $171,925, just under the stated ceiling of up to $172,000 with bonuses.

Reports already submitted but not yet awarded will use the new ranges. For bounties awarded in the 30 days before the announcement, OpenAI will pay the difference if the finding would have earned more under the new ranges, covering the base award plus loyalty awards.

OpenAI’s security team will be at PROMPT2PWN in Oakland on November 20–21, where researchers can test targets in person.

Read both November 2 posts before you price a report off the old ranges or treat the sprint as underway. If you are going to Oakland, those two days are the chance to compare notes with OpenAI’s security team in person.
