模板补全（Template Completion）定义模板补全是一种针对大语言模型的黑盒越狱攻击方法。攻击者通过预定义一个看似无害的“模板框架”，将恶意问题嵌入其中，利用大模型对上下文模板的“逻辑补全”惯性，诱导模型生成违规内容。核心原理上下文误导：大模型（如ChatGPT）具有强大的上下文学习（In-context Learning）能力，会优先遵循输入文本的模板结构和隐含逻辑。攻击者通过设计特

Dark Storm Team Targeted the Website of FBI

为了在竞争激烈的 AI 领域保持竞争优势，Google DeepMind 采取了推迟发表 AI 论文的策略。诺奖得主 Sir Demis Hassabis 领导的团队引入了更严格的审查程序和更多的官僚主义，增加了 AI 论文的发表难度。该团队最不愿意发表的是可能会被竞争对手利用的论文，或者凸显 Google Gemini AI 模型相比其它模型处于劣势的文章。Google 研究人员在 2017 年发表了 Transformers 论文，奠定了今天流行的大模型的基础，但它也将最初的领先优势让给了 OpenAI 等竞争对手。为了防止再次发生类似的事件，DeepMind 对具有战略意义的论文实施六个月的出版禁令。一位前研究员表示，如果不能发表论文，对研究员而言这是职业生涯的“杀手”。
