OpenAI launches the GPT-5.6-Cyber model, enhancing vulnerability discovery and security research capabilities

OpenAI announced the expansion of its cybersecurity defense program Daybreak and launched the GPT-5.6-Cyber model specifically for the cybersecurity field, aimed at helping authorized security researchers and defense teams enhance their vulnerability discovery, threat analysis, and security testing capabilities. As attackers increasingly leverage AI to launch faster and larger-scale cyberattacks, defenders need to gain advanced AI capabilities in advance.This Daybreak offers two types of access: Daybreak Blue is aimed at most defense teams, providing general models such as GPT-5.6 Sol for vulnerability discovery, secure code review, malware analysis, incident response, and patch validation; Daybreak Red is aimed at advanced security research, providing GPT-5.6-Cyber for authorized vulnerability research, vulnerability validation, and security testing. GPT-5.6-Cyber is trained on GPT-5.6 Sol and optimized for cybersecurity tasks, including discovering zero-day vulnerabilities and analyzing exploit chains. It has been used in actual vulnerability research and has identified high-risk vulnerabilities in software, including the Chrome V8 JavaScript engine. Additionally, OpenAI stated that GPT-5.6-Cyber has also helped discover high-risk vulnerabilities in various domains, including privilege escalation vulnerabilities in mobile operating systems, remote code execution vulnerabilities in databases, and hundreds of privilege escalation vulnerabilities in operating system kernels.OpenAI also emphasized that Daybreak Red will only be accessible to approved individuals and organizations, controlling access through measures such as authentication, account security, monitoring, usage restrictions, and legal disclaimers. The company stated that it will continue to strengthen security monitoring, access management, and model security testing to reduce the risk of advanced cybersecurity models being abused.

The Central Cyberspace Affairs Commission recently announced the progress of the first phase of the "Clear and Bright: Rectifying AI Application Chaos" special action. Since its launch in April 2026, this action has focused on issues such as large models not being registered as required, insufficient review and filtering capabilities, AI data poisoning, and inadequate implementation of content labeling. As of now, the first phase has dealt with over 14,000 AI products, including non-compliant websites, applications, and intelligent agents, cleaned up more than 6 million illegal and non-compliant pieces of information, handled over 26,000 non-compliant accounts, and removed over 1,300 non-compliant AI products and 9 non-compliant open-source datasets.During the special action, many local cyberspace departments have taken targeted measures such as establishing coordinated regulatory mechanisms and setting up reporting areas. Key platform companies such as Huawei, Alibaba, Zhiyu, and DeepSeek have also successively improved their registration review, content interception, and data anomaly detection mechanisms. The Central Cyberspace Affairs Commission stated that the next phase of governance will focus on cracking down on prominent issues such as the use of AI technology to create and disseminate false information, spread vulgar content, impersonate others, infringe on the rights of minors, and engage in internet water army activities, further increasing enforcement efforts and urging platforms to enhance their prevention and governance capabilities.

OpenAI expands its cybersecurity program Daybreak, launching a dedicated defense model GPT-5.5-Cyber

OpenAI announced a comprehensive expansion of its cybersecurity program Daybreak, aimed at leveraging artificial intelligence to accelerate the discovery and automatic remediation of software vulnerabilities. The core of this expansion is the full version dedicated model GPT-5.5-Cyber launched for trusted defenders. It is reported that this model has set the highest score records in multiple cybersecurity benchmark tests, surpassing GPT-5.5's 81.8% and competitor Mythos 5's 83.8%, significantly improving the accuracy of vulnerability scanning and patch generation. At the same time, the synchronously updated Codex Security plugin has been deeply integrated into the developer workflow, supporting fully automated codebase scanning, threat modeling, and patch generation.In terms of ecosystem development, OpenAI has launched an exclusive partner program, allowing compliant security service providers to integrate GPT-5.5 with specific permissions into their commercial products; and has initiated the "Patch the Planet" program in collaboration with organizations like Trail of Bits to assist over 30 foundational open-source projects such as Python and Go in implementing vulnerability fixes. In addition, OpenAI revealed that it is currently engaged in deep cooperation with governments and institutions from multiple countries, including the United States, the United Kingdom, France, and Japan, to jointly enhance the cybersecurity capabilities of global critical infrastructure.
