OpenAI GPT-6 Astra Reaches 100% Exploit Generation Accuracy on ExploitBench

OpenAI has unveiled GPT-6 Astra, its latest model that demonstrates unprecedented capability in generating working exploits from known vulnerabilities. The model scored a perfect 100% on ExploitBench, significantly outperforming the previous GPT-5.6 Sol at 78.5%. In tests involving recently disclosed vulnerabilities, Astra achieved arbitrary code execution in 39% of cases compared to 11.5% for its predecessor and discovered two previously unknown zero-day flaws. Due to these capabilities, OpenAI has restricted the public release to safe code analysis and patch development only, blocking requests for proof-of-concept exploits. Expanded access for vulnerability research and malware analysis will be provided through the Daybreak program to selected defenders, while the company adds stronger jailbreak protections and activity monitoring.
