OpenAI launches GPT-5.6-Cyber to help defenders find vulnerabilities before attackers do
OpenAI introduced GPT-5.6-Cyber, a specialized model for cybersecurity defenders. The company claims it resolves 98.5 percent of security queries and has already surfaced two unknown Chrome vulnerabilities.
OpenAI has unveiled a new specialized model, GPT-5.6-Cyber, targeting the cybersecurity sector. This release marks a shift toward domain-specific AI applications designed to assist security teams in identifying threats proactively rather than reactively.
According to the company, the model demonstrates high efficacy in handling security-related queries, reportedly answering 98.5 percent of requests that might otherwise be restricted. Additionally, OpenAI states the system has already detected two previously unknown vulnerabilities within Chrome browsers.
Such tools aim to narrow the gap between attackers and defenders by automating vulnerability discovery. If effective, this could reduce the window of exposure for critical software flaws, potentially lowering the risk of exploitation in the wild.
This launch reflects a broader trend of AI labs moving beyond general-purpose assistants into specialized enterprise solutions. Cybersecurity remains a high-stakes domain where accuracy is paramount, suggesting rigorous testing will be required before widespread adoption.
