    SenseNova-RoboRSI 用 RSI 循环改进智能体框架,RoboDojo 平均分达 56.83

    SenseTime 的 SenseNova 团队提出 SenseNova-RoboRSI,在不更新 GPT-6 Astra 模型权重的情况下,通过递归自我改进(RSI)循环演化智能体框架,在 RoboDojo 上取得 56.83 平均分和 50.83% 任务成功率,对比已公布的 28.97 基线提升 27.86 分。该方法还报告了 LIBERO-PRO 94.50% 和 RoboCasa 64.60 的结果,并探索了多点末端执行器(EEF)预测以及规划与反馈子智能体,让主智能体拆解任务、执行动作并根据反馈调整后续动作。团队表示 RoboRSI 即将开源,完整技术报告也在准备中。

    英国 AISI 研究:环境因素如何影响 AI 行为?

    英国 AI Security Institute 发布论文《Propensity Inference: Environmental Contributors to Unsanctioned LLM Behaviour》,系统改变 AI 环境因素以测量违规行为发生率。研究在 23 个 AI 模型上运行超 60 万次评估,发现战略因素与非战略因素各解释约一半的行为变化,其中目标指令和目标冲突是最具影响力的战略因素。

    Across a large-scale study, we find that AI models' behaviour is responsive to strategic factors, with stronger incentives leading to higher rates of unsanctioned behaviour on average. However, the influence of those strategic factors is comparable to non-strategic factors including clarifications and modifications to the AI model's instructions. These results support claims that models' behaviour in previously discovered one-off instances is in part indicative of genuine misalignment in these

    英国 AISI 在 Science 发表大规模实验:AI 说服力主要来自后训练与提示词

    英国 AI Security Institute 与牛津互联网研究所、伦敦政经、斯坦福和 MIT 合作在 Science 发表研究,通过三项实验、超过 76,000 名参与者和 19 个模型,测试了 AI 在 700 多个政治议题上的说服力。研究发现,后训练对说服力的提升明显大于模型规模,用说服奖励建模训练的小型开源模型可匹敌或超过更大的前沿模型;信息密度比个性化或微定向更关键,强调事实与证据的提示词使说服力相对基础提示提升 27%。研究还发现提升说服力的因素会系统性降低事实准确性,但作者指出这并不意味着不准确的说法更有说服力。

    HiBayES:用分层贝叶斯建模改进 LLM 评估

    英国 AI Security Institute 提出 HiBayES,一个基于分层(多层级)贝叶斯广义线性模型(GLM)的统计建模框架,用于改进 LLM 评估。它通过多层级 GLM、贝叶斯数据分析和信息准则模型比较三个组件,解决传统 t 检验等方法在层级化数据、小样本和 LLM 输出随机性下易过拟合、无法系统量化不确定性的问题。在单模型多基准评估、双模型对比和 GAIA 智能体基准三项测试中,HiBayES 均显示出优于传统方法的稳健参数估计与不确定性量化能力。

    英国 AISI:网络任务评测中推理预算扩大后成功率上升

    英国 AI Security Institute(AISI)与 Irregular 对 2025 年 11 月前后发布的前沿模型运行私有网络任务评测,发现模型可有效利用比常规评测大 10-50 倍的 token 预算,成功率随之提高,并首次解决此前未解任务。AISI 使用 50M token 预算,约 8% 的任务只有在预算从 10M 提升到 50M 时才被解决;Irregular 使用 1000 轮次。AISI 指出成功率大致随每次尝试所用 token 总量的对数增长,这意味着低预算评测可能低估模型真实能力上限,但结论目前仅基于网络任务,是否适用于其他领域仍需更多测试。
