A model OpenAI says can find unknown vulnerabilities and write working exploits raises the stakes for both attackers and defenders of software systems.
Key points
- OpenAI says GPT-6 Cyber developed 948 working exploits in the Linux kernel. source ↗
- OpenAI says the model found 81 previously unknown vulnerabilities in Firefox. source ↗
- The model is built to find software vulnerabilities, develop exploits, and propose patches. source ↗
- OpenAI claims these results significantly exceed its predecessor's. source ↗
The data
948
Working exploits in the Linux kernel that OpenAI says GPT-6 Cyber developed
OpenAI also claims 81 previously unknown Firefox vulnerabilities; neither figure is independently verified in the report.

Practical applications
- Security teams can evaluate GPT-6 Cyber against their own codebases to surface flaws before an outside party does.
- Browser and kernel maintainers can cross-check the claimed 81 Firefox vulnerabilities and 948 kernel exploits against their own trackers and shipped versions.
- Defenders can test the model's suggested patches in staging as a triage starting point rather than merging them blindly.
Context
AI models are increasingly applied to vulnerability research, scanning code for flaws and generating proof-of-concept exploits. Such a model is dual-use: the same capability that helps defenders patch software can help attackers break in. OpenAI describes GPT-6 Cyber as a large step up from a predecessor model in this line.
What to watch
- Confirmation from Mozilla or Linux kernel maintainers, such as CVE assignments or merged fixes, would independently validate OpenAI's claimed numbers.
- OpenAI's access and release terms for GPT-6 Cyber will show how it plans to keep a dual-use exploit capability from misuse.
