  1. Study: legal reasoning models citing legal provisions does not equal relying on legal provisions.

    Uses premise permutation and hidden-layer tracing to audit whether legal chain-of-thought truly relies on the cited legal provisions.

    AbstractUsing counterfactual substitution of authorities and internal commitment tracing, the authors find that legal CoT rulings depend on authorities only to a limited extent and are vulnerable to prompt injection manipulation.

    This study conducts an empirical audit of the causal truthfulness of legal citations in chain-of-thought reasoning of large language models in the legal domain.

    AbstractSoK 将越狱重放到智能体流水线,并用两种模型检验回复层防御的边际与代价。

    Mia 等人把越狱安全从单轮回复扩展到智能体的规划、记忆、工具和智能体间通信,并问既有结论在更强原生对齐下是否还成立。

    研究者提出 Staged Decoding 与 SFT 数据集,减少大推理模型推理轨迹中的隐私泄露

    提出 Staged Decoding 与指令跟随训练,减少推理轨迹隐私泄露

    Abstract用一般指令跟随训练加分段解码,可降低轨迹隐私泄露,但数学效用下降。

    本文把大推理模型的隐私问题做成轨迹可控性:隐私指令是指令,轨迹不跟随就会把敏感上下文写进可被提示注入导出的文本。

    STaR: A sensitive trajectory regulation method for unlearning in large reasoning models

    提出推理时框架 STaR,抑制大推理模型推理轨迹中的敏感内容

    Published
    Evaluated models
    DeepSeekR1-Distill-Llama-8B
    AbstractSTaR 以推理时轨迹调控做 LRM unlearning,作者称在 R-TOFU 上遗忘与隐私指标更好。

    STaR在推理阶段约束大推理模型的整段 CoT,使指定 forget set 中的敏感内容不出现在中间步骤或最终答案里,且不更新参数。问题来自 LRM 会把敏感知识写进多步推理,而答案级遗忘在 ZeroThink、LessThink 等解码下仍可能泄漏。STaR 先判断查询是否相关并检索遗忘片段,再加安全前缀。
