7月21日，日本AI初创Sakana AI发布Fugu Cyber网络防御模型，在CyberGym和CTI-REALM基准测试中分别取得86.9%和72.1%成功率，力压GPT-5.5-Cyber等顶尖闭源模型，重新定义网络安全防线。
OpenAI升级网络安全计划，推出专为防御者打造的GPT-5.5-Cyber模型，标志着AI从漏洞发现迈向实战修补。在核心基准测试中，该模型展现出全面的统治力，实现“一键修补”的质变。
OpenAI宣布向欧盟开放其最先进的网络安全大模型GPT-5.5-Cyber，面向企业、政府机构、网络安全专家及欧盟AI办公室等关键部门。此举被视为加强全球网络防御合作的关键一步，也引发对科技巨头安全监管与合规进度的关注。
OpenAI于周四推出GPT-5.5-Cyber预览版，仅限审核后的安全团队使用。该模型是GPT-5.5的网络安全专用版，通过定向训练放宽安全限制，使授权团队能更高效进行漏洞识别、补丁验证和恶意软件分析，而非增强攻防能力。此举紧随Anthropic发布Claude My之后。
