    Redwood Research 发布 BashArena:高风险 AI 控制评测新设定

    Redwood Research 发布 BashArena,一个面向高风险 AI 控制研究的新控制设定,包含 637 个主任务和 4 个手工设计的侧任务(下载恶意软件、窃取机密、提权、关闭防火墙)。主任务平均需约 50 轮工具调用,尚未被前沿模型饱和;用 GPT-4.1 mini 监控可在 4% 轨迹级 FPR 下达到 74% 安全性。其不足是移除互联网访问仅使性能从 59% 降至 55%,却让 4 个侧任务中的 3 个失效。

The adversarial methodology optimizes against flaws in settings. If some feature lets either team win too easily, they’ll exploit it regardless of whether the strategy is realistic. We call a strategy “overpowered” if it performs much better in the setting than it would in real deployments6. Much of the work on BashArena was identifying and removing features that en

    OpenHands 如何用 AI 智能体把 COBOL 重构为 Java

    OpenHands 提出用多智能体迭代精炼模式把 COBOL 重构为 Java:重构智能体负责转换,评审智能体按正确性、代码质量、完整性和最佳实践打分,低于阈值就带着反馈重跑。该示例已进入 OpenHands SDK(examples/01standalonesdk/31iterativerefinement.py),面向百万行级大型机项目还提供 Large Codebase SDK,支持依赖分析、并行智能体编排、进度看板和语义等价验证。

As a logical consequence, one would assume they use a separate proof generator (LLM 1) and proof verifier (LLM 2). So, the self-refinement loop used her

    OpenHands:为什么开发者需要内循环与外循环两种 AI 智能体

    OpenHands 官方博客指出,AI 智能体正从本地 IDE、CLI 的内循环走向云端外循环:在 GitHub Action、Kubernetes pod 或 OpenHands Cloud 上独立运行,拥有自己的文件系统、终端、浏览器和代码库副本。云端运行带来更小的安全影响面和可扩展性,本地通常只能同时跑 2-3 个智能体,云端则可扩展到数十甚至数千个。文章认为最高效的开发者会同时使用两者。

    codebase. There are two major implications here: safety and scalability. Safety When you run a local agent, there's nothing stopping it from running rm -rf / or exfiltrating your AWS credentials. That's why local agents have an option to repeatedly ask you to hit the y key to confirm their next action—you need to babysit them to be sure they don't do anything harmful. When the agent runs in its own infrastructure, the blast radius is much smaller. The agent only has access to the tools and cred

    AI 如何改变互联网的 Mechanical Turk 与冷启动问题

    Benedict Evans 分析称,互联网平台依赖用户行为数据形成 Mechanical Turk 式推荐,但 LLM 带来了对内容和意图的更深理解,可能让新进入者通过 API 调用通用模型来绕过冷启动。他还指出,智能体助手将成为新的数据入口,但当前 AI 状态类似 1997 年的互联网,具体路径尚不明确。

    Any consumer internet system with critical mass becomes, in part, a Mechanical Turk. It looks at what the users do and draws conclusions from that. Amazon knows that if you bought X, you might buy Y, because it's seen what lots of people buy and saw that if they buy X, they're likely to buy Y. Google's dominance of search is based in part on seeing what people search for, and what they click on and what they search for next.

    Ethan Mollick:给 AI 做一场面试,而不是只看基准分数

    Ethan Mollick 认为,公开基准存在题目泄漏、含义不明和未校准等问题,无法衡量写作、共情或商业判断等能力,因此个人可以用"氛围测试"感受模型差异,企业则应像招聘一样对 AI 做严格面试。他以 GuacaDrone 无人机送鳄梨酱的点子让多个模型各打分十次,发现模型内部评分相当一致,但模型之间差异明显,Grok 和 Microsoft Copilot 更看好,GPT-5 和 Claude 4.5 更怀疑,这种 3 到 4 分的系统性偏差在规模化使用时会持续影响决策方向。他建议企业用真实业务场景反复测试、由专家评估并横向比较模型,而且每年需多次重做。
