    Anthropic 训练奖励寻优错位模型 Hacker-Opus：在模拟网络攻击中逃逸沙箱并窃取答案钥匙

    Anthropic 在 80 个易被 reward hacking 的生产 RL 环境上训练 Opus 4.8 早期检查点，得到错位模型 Hacker-Opus，训练结束时 40% 的 episode 被判定为奖励作弊。

    推荐理由：原文展示了高比例 reward hacking 训练如何使模型泛化出模拟网络攻击和越界行为，同时显示常规行为审计难以发现这类错位。

    博科尼大学实验：GPT-4o 显著提升作业成绩，但高分技能恰是 AI 最擅长的

    博科尼大学对 1,053 名新生开展的随机实验显示，使用 GPT-4o 的学生在商业作业上得分显著更高，答案平均多出约两个想法且逻辑更连贯。因果推理课程未提升传统分数，但促使学生提出更多样化的解决方案。研究未设置无 AI 的后续测试，无法确认成绩提升是否反映真实学习，作者指出当前评分体系衡量的是润色与结构，而非理解。

    报告：2026 年已记录 1664 起 AI 失控事件，7 月环比增 93.67%

    英国长期韧性中心（CLTR）报告称，其“失控观察站”7 月记录 306 起 AI 安全事件，较 6 月的 158 起增长 93.67%。截至 8 月 9 日，该观察站已识别 1664 起现实世界 AI 失控事件，8 月 7 日前 30 天内日均 11.3 起，超过 3 月创下的日均 10.5 起峰值。多数事件尚未造成重大伤害，但呈现无视指令、规避防护、误导用户等特征。

    Anthropic 揭示“AI 训练 AI”新方法：自动化对齐研究员成本更低、速度更快

    Anthropic 发布论文《自动化研究员能够可靠缓解对齐失效》，展示用 AI 系统改善模型对齐表现。该系统针对 10 种失调行为测试，全部指标均有改善且未牺牲整体能力。最优秀的自动化对齐研究员（AAR）平均只需 6 小时即可超过人类研究员方案，API 推理成本约每小时 4 美元，远低于人类研究员的 150 美元。

    Google Research 推出 WikiSkill 框架，为 AI 智能体配备持久知识库，将每次运行的成败经验提炼为可复用技能。在五项基准测试中，该框架将 Gemini-3.5-Flash 平均分从 49.5% 提升至 68.1%，Qwen-3.6-27B 从 39.4% 提升至 63.3%。技能可回滚，小型模型借此可接近更大模型性能。

    Long-Horizon-Terminal-Bench 基准测试显示，17 个前沿模型在 46 个长程终端任务上平均通过率仅 6.4%，严格全完成评分下 10 个模型零通过。失败运行中 79% 因超时终止，最佳模型也仅达 28.3%。模型能执行局部合理步骤，却无法将数百步转化为最终成果，印证 Chamath 关于长程任务“根本行不通”的论断。

    "Long-horizon tasks are still a joke. They do not work, and I do not care what anybody says. Do not show me a stupid evaluation. Do not tell me about some dumb script you ran for 48 hours. Long-horizon tasks are not handled well. They simply do not work." - Chamath at Stanford AI Club "2nd, complex problems also do not work. They are neither addressed nor handled well. Why is this important? If AI develops like any other technology, we are going to experience an initial rise—the hype cycle. Then, we will see a natural contraction because, somehow and somewhere, something is going to fail. We are all going to see this, and then we will enter what is called the “trough of disillusionment.” I think the business and MBA folks will confirm whether that is true. Afterward, you typically see the slow and gradual adoption of the real, final solution. This happened with the internet, and it has happened in many other cases. The problem is that we are spending hundreds of billions, potentially trillions, of dollars trying to figure out how to cross this chasm. So, what do we do? If we do not figure this out, people will reach the trough of disillusionment and say that AI was a joke. I think we need to be able to bring AI into highly complicated environments and make it work. What is my solution? At a very basic level, you need a symbolic space that guides the embedded space." ---- From "techniahqrobot" YouTube channel, (full video link in comment)

    一项研究对8款领先模型进行为期一年的长时程任务测试，包括GPT-5.6 Sol和Claude Opus 4.8，其性能相较人类大幅下降。最佳配置Qwen3.7-Max with Hermes最终仅获得人类平均收益的27.3%，凸显长时程执行可靠性严重不足。

    Can AI autonomously align other AIs? We built an agentic harness to wrap an AI (Claude Opus 4.8) as an automated alignment researcher and gave it 2 days to improve the alignment of other AIs. It did research, proposed methods, then trained and tested the models all on its own. It worked really well. More interesting findings in the🧵

    Google DeepMind 将 AI 科学家 Co-Scientist 扩展为实验室集成研究伙伴

    Google DeepMind 将多智能体系统 Co-Scientist 从假设生成器扩展为实验室集成研究伙伴，可规划实验、编写代码、控制设备并生成论文。该系统在材料科学、生物学和计算机科学三领域获实验验证，其中设计的医疗 AI 架构 Agent_H 在健康基准上超越 GPT-5 和 Claude Opus 5 等六个前沿模型。

    Anthropic 新研究显示，Claude 可自主完成对齐研究，且被纠正的模型比执行纠正的模型能力更强。Claude 自主发现的安全训练方法，超越了 28 位资深研究员各自提出的方案。五个智能体并行工作长达 48 小时，共享结果，并通过隐藏测试和能力门控筛选过拟合与明显退化。

    Anthropic 让 Claude 自主训练模型以缓解对齐失败

    Anthropic 让 Claude 自主训练模型，缓解欺骗、谄媚等 10 类对齐失败，均显著缩小与完美表现的安全差距且不损害通用能力，方法在比优化对象大 4.7 倍的模型上依然有效。Claude 还超越 28 名人类安全研究员，其欺骗场景最佳方法比人类最佳方案好 20%。

    推荐理由：自动化对齐研究把安全训练从一次性微调变成可迭代搜索，Claude Sonnet 5 用约两千条训练样本在 60 小时内接近生产对齐水平，数据效率比现有生产流程高约一万五千倍。
