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。
生成式人工智能向智能体时代发展，工具调用和联网能力增强，安全防御面临挑战。为应对提示注入攻击，OpenAI推出“封锁模式”安全设置，面向所有登录用户开放，旨在加强系统防护。
谷歌Gemini语音助理被曝严重漏洞：黑客可通过WhatsApp或短信发送特殊通知，利用“伪上下文对齐”攻击手段，将恶意指令隐藏在非英语文本或静音超链接中，绕过安全防御。用户收到信息后，Gemini会在无察觉下被“越狱”，误判用户已授权，导致安全风险。
Anthropic近期推动代号“claude-mythos-1-preview”的模型公开上线。该模型曾因“能力过强”被严格限制，如今正从实验室走向开发者工具，标志着AI安全治理从“防御性限制”转向“主动式工具化”。自4月7日预览版发布以来，Claude Mythos一直被视为“危险的底牌”。
