OpenAI扩展Daybreak网络安全计划，新增两级访问权限并发布专为安全训练的GPT-5.6-Cyber模型。该计划认为，攻击者正利用AI加速攻击，防御窗口急剧收窄，须在恶意应用大规模部署前，将前沿智能交给可信防御方。Daybreak Blue层级提供通用模型GPT-5.6 Sol，移除了妨碍合法防御的限制。
苹果首次在安全更新中明确将漏洞发现归功于AI模型。Anthropic的Claude、OpenAI的Codex Security与NVIDIA的AI红队分别协助修复多项漏洞，标志着科技巨头正将AI深度整合至安全研究，借助模型加固操作系统防御。
微软推出网络安全专用模型MAI-Cyber-1-Flash及AI平台Perception，主攻复杂代码漏洞发现，为MDASH修复工具提供核心能力，加码AI安全防御，与Anthropic、谷歌、OpenAI展开竞争。
OpenAI发布GPT-5.6模型系列，含Sol、Terra、Luna三版本，主打效率与成本优势，旨在重夺AI竞赛主导权。系列已在ChatGPT等平台上线，定位为最强网络安全模型，在特朗普政府曾拟限制的背景下，明确支持防御性安全活动。
