AI 材料发现的闭环走到哪一步了:GNoME、A-Lab 与自动化实验室的三年起伏
GNoME 一次「发现」38 万个稳定晶体,A-Lab 宣称机器人 17 天合成 41 种新材料——随后被质疑、更正为 36 种。预测模型狂飙突进,实验验证却成了瓶颈。截至 2026 年 10 月,从预测到合成的闭环真正打通了吗?

一篇读懂 LLM-as-a-Judge:让模型给模型打分,靠谱吗
GPT-4 当裁判与人类偏好的一致率 85%,超过了人类彼此之间的 81%——这是 LLM-as-a-Judge 立身的实验,但它交换位置后的一致率只有 65%,一个 token 就能操纵打分,模型版本一漂移榜单就作废。本文拆解机器裁判的奠基实验、三种已知偏差与缓解手段、工程化成本,以及什么时候不该用它。

从实现者到塑造者:「高自主权」为什么常常落不了地
系列第 ④ 篇(收官),对应技能地图第 17–20 格「塑造构建」。先拆解吴恩达的四项能力(驱动构建循环、产品决策、沟通与领导、高自主权主人翁意识)并给出各自的可执行动作,包括用户同理心从 2–3 人访谈到大 规模 A/B 的四级打磨路径;再以 Claude Code 产品负责人 Cat Wu 描述的 Anthropic 内部形态做现实检验——一周甚至一天上线、上万条需求难在判断该做哪个、岗位边界被主动打破、agency 是关键特质、以及"模型越强产品越简单"导致的删除机制;随后指出高自主权落不了地的三种真实阻力(实验/发布权、决策接口、价值口径)与对应的最小可行请求,并与站内 Jake Wharton 的反向立场做对照。附个人与管理者各四条行动清单,及四篇系列总览。

深度研究|Anthropic 九月威胁情报报告全解:AI 从「助手」变成「编排者」,以及七家中国实验室的蒸馏之争
154 页、约 40 个真实案例、七大危害领域。Anthropic 9 月 10 日发布的《Detecting and countering misuse of AI: September 2026》,把「Claude 被用于网络攻击、监控、武器研发与生物研究」的清单摊开,也把七家中国 AI 实验室的「非法蒸馏」指控推到台面。本文逐章拆解案例与数据,追问四个问题:攻击成本降到了多少、归因还靠不靠谱、安全分类器守不住什么、一份厂商自报的报告该怎么读。

美联储重启加息倒计时:对 A 股意味着什么?——穿透六条传导链的复盘与推演
8月CPI落地后FedWatch显示9月加息概率升至约90%,高盛改口、20家机构中16家预期加息。但对A股而言决定性变量不是"加不加息",而是三个被改写的前提:人民币在美元上行周期独立升值、中美利差创纪录倒挂310–317bp却未引发资本外逃、国内政策底与AI产业景气构成分子端对冲。本文拆解六条传导链、复盘三次加息周期的三种答案,并给出行业冲击地图与观测清单。

当 Agent 接管流水线:AI 增强 CI/CD 的 2026 实证、边界与治理
AI 没有消灭交付瓶颈,只是把瓶颈从"写代码"搬到了"验证代码"。本文基于 2 篇 arXiv 论文、DORA 2025 报告与 2026 年三份行业基准(LinearB 8.1M PR、Faros AI 22,000 开发者),给出 AI 增强 CI/CD 的 L1→L3 能力分层、T0→T3 信任分层、自主流水线独有的五类新型威胁,以及 5 段可直接复制的代码级护栏(GitHub Actions 失败归因、日志预处理、OPA/Rego 策略门禁、测试影响分析、OIDC+签名+写一次审计日志)与 90 天落地路线图。关键数据:任务吞吐 +33.7% 但评审耗时 +441.5%、生产事故/PR 比值 +242.7%;AI PR 30 天合并率 32.7% vs 人工 84.4%;论文实验中 Lead Time −35%、CFR −38%、MTTR −43%,AI 干预准确率 87.5%、人工否决率 14.3%、零策略违规。
