7月21日，日本AI初創Sakana AI發佈Fugu Cyber網絡防禦模型，在CyberGym和CTI-REALM基準測試中分別取得86.9%和72.1%成功率，力壓GPT-5.5-Cyber等頂尖閉源模型，重新定義網絡安全防線。
OpenAI升級網絡安全計劃，推出專爲防禦者打造的GPT-5.5-Cyber模型，標誌着AI從漏洞發現邁向實戰修補。在覈心基準測試中，該模型展現出全面的統治力，實現“一鍵修補”的質變。
OpenAI宣佈向歐盟開放其最先進的網絡安全大模型GPT-5.5-Cyber，面向企業、政府機構、網絡安全專家及歐盟AI辦公室等關鍵部門。此舉被視爲加強全球網絡防禦合作的關鍵一步，也引發對科技巨頭安全監管與合規進度的關注。
OpenAI於週四推出GPT-5.5-Cyber預覽版，僅限審覈後的安全團隊使用。該模型是GPT-5.5的網絡安全專用版，通過定向訓練放寬安全限制，使授權團隊能更高效進行漏洞識別、補丁驗證和惡意軟件分析，而非增強攻防能力。此舉緊隨Anthropic發佈Claude My之後。
