OpenAI has revealed GPT-6 Cyber, a new artificial intelligence model that has discovered 81 previously unknown high-severity Firefox vulnerabilities and developed working exploits for 948 distinct Linux kernel flaws.

The company announced the model on Thursday, saying it significantly improves on earlier AI models in finding software vulnerabilities, validating their impact, and helping developers create fixes.

During security testing, GPT-6 Cyber discovered 81 previously unknown high-severity vulnerabilities in Firefox and helped develop patches, many of which Mozilla has already released.
