OpenAI announced an upgrade to its Daybreak network defense toolchain, officially launching the full version of the GPT-5.5-Cyber model tailored for cybersecurity defense scenarios.In the CyberGym benchmark test, which evaluates the ability of AI agents to reproduce known vulnerabilities, GPT-5.5-Cyber achieved a single-model score of 85.6%, surpassing GPT-5.5’s 81.8% and Anthropic Mythos 5’s 83.8%.OpenAI stated that as AI significantly enhances the efficiency of vulnerability discovery, the core bottleneck in cybersecurity is shifting from "finding vulnerabilities" to "automatically fixing them." To this end, the company has simultaneously upgraded the Codex Security plugin, enabling developers to automatically analyze vulnerabilities and generate fix patches within the Codex environment. Since the preview release in March this year, Codex Security has scanned over 30 million code commits and autonomously confirmed fixes for 500,000 security defects. The new version also supports CodeQL query integration and SARIF standard file export.Additionally, OpenAI has partnered with organizations such as Trail of Bits and HackerOne to launch the "Patch the Planet" open-source security project. This initiative provides ChatGPT Pro subscriptions and API credits to over 30 major open-source projects, including cURL and Go, with security expert teams manually verifying patch quality. Regarding the Daybreak partner program, security vendors such as Palo Alto Networks and Wiz have already integrated the relevant capabilities.

OpenAI has officially launched the GPT-5.5-Cyber model and the "Trusted Access for Cyber" (TAC) framework designed for cybersecurity defenders. Simultaneously, GPT-5.5-Cyber has been opened for a limited preview to defenders responsible for critical infrastructure, supporting specialized cybersecurity workflows.TAC is an identity and trust-based framework aimed at ensuring that enhanced AI capabilities are wielded by verified defenders. Defenders verified through this framework will encounter fewer instances of model refusal when performing tasks such as vulnerability identification, triage, malware analysis, binary reverse engineering, and patch verification. Starting from June 1, 2026, individual members accessing this capability will be required to enable advanced account security protection.OpenAI is currently collaborating with security vendors including Cisco, CrowdStrike, and Palo Alto Networks to accelerate the defense cycle of the security ecosystem through GPT-5.5, enhancing the efficiency of vulnerability research, patching, monitoring, and supply chain security.
