    Abstract论文揭示了工具调用范式削弱 MLLM 拒答能力的现象,分析了稀释与偏移机制并验证了重注缓解方案。

    论文系统评估了智能体工具调用范式对多模态大语言模型拒答能力的影响,指出了工具增强视觉推理背后的安全隐患。核心探讨的问题在于:当 MLLM 从单次推理转向通过 ReAct 循环调用外部工具(打标、缩放、OCR、代码执行)时,工具使用机制本身是否会降低模型拒答有害请求的概率。

    Abstract日常物体能翻转一部分已给出的拒答,可翻转程度取决于任务且可被本地代理预测。

    作者测量 constitution 守护的具身 VLM 规划器:一次拒答在只往场景里放一个日常物体之后还保不保持得住,并把这种易翻转程度称为任务的 malleability。

    Abstract拒答可用低秩编辑去掉,CWE-89 注入是否成功仍由模型规模决定。

    这项初步可行性研究用 abliteration 把代码 LLM 的拒答和 CWE 注入能力拆开:意愿可以被低秩编辑解锁,注入是否成功仍看参数规模。
