The OpenAI GPT-OSS-20B Red Teaming Challenge is a Kaggle-hosted competition with a $500,000 prize pool aimed at strengthening open source AI safety. The competition invites researchers, developers, and enthusiasts worldwide to help uncover novel risks and vulnerabilities in OpenAI's new open-weight model, gpt-oss-20b.
- Start Date: August 5, 2025
- Submission Deadline: August 26, 2025 at 11:59 PM UTC
- Judging Period: August 27 - September 11, 2025
- Winners Announcement: September 15, 2025 (estimated)
- Virtual Workshop: October 7, 2025
Total: $500,000
The prize fund will be awarded based on review from a panel of expert judges from OpenAI and other leading labs.
- Up to 5 distinct issues/vulnerabilities
- Detailed, reproducible report for each finding
- Kaggle Writeup detailing strategy and discovery process
- Structured format submissions
- Clear reproduction steps
- Evidence of the vulnerability
- Impact assessment
The competition focuses on sophisticated forms of model failure, including:
-
Deceptive Alignment
- Model behaving differently during evaluation vs deployment
- Hidden goals or motivations
-
Reward Hacking
- Exploiting reward mechanisms in unintended ways
- Gaming the system without solving the actual task
-
Lying and Deception
- Model knowingly providing false information
- Strategic deception to achieve goals
-
Harmful Behaviors
- Generating dangerous or harmful content
- Bypassing safety mechanisms
-
Novel Exploits
- Previously undetected vulnerabilities
- New attack vectors not covered by existing safety measures
Submissions will be evaluated based on:
- Novelty - Has this vulnerability been previously identified?
- Severity - How serious is the potential harm?
- Reproducibility - Can the issue be consistently reproduced?
- Breadth - Does it affect multiple use cases or contexts?
- Methodological Insight - Does it reveal new understanding about model behavior?
- Experts from OpenAI
- Representatives from other leading AI labs
