罗福莉讲的是模型能力，但每一条都藏着对场景落地的启示
上周看完张小珺对罗福莉的 3.5 小时访谈，我做了笔记。 这场访谈在朋友圈、行业群里被反复刷屏。每一条核心判断都被截图—— “Anthropic 的路径是正确的，这是当下共识。” “1T 是入场券。” “卡的比例从 3 : 5 : 1 变成 3 : 1 : 1。” “中层模型 + 好框架，85% 任务接...

工程师的两条上行路：从 Software Engineer 到 Business Builder 和 Harness Engineer
Naval 上周在他的播客里说了一句话：纯软件已经不可投资。 这句话被广泛转发的版本是”rapidly becoming uninvestable”——正在加速失去可投资性。但他在播客里特意说，那是被稀释过的说法，他真正想说的是：”Pure software is uninvestable. Full stop...
激动人心的噪音里，你的护城河反而变厚了——一个写给 AI 工程化落地从业者的反常识判断
GPT-5.5、Claude Opus 4.7 双双发布之后，AI 圈最热的叙事是”模型自主、agent 接管、编排消失”。但在保险理赔、医疗诊断、金融风控这些垂直场景里，真正在升值的不是模型自主性，而是工具的可解释性和编排的确定性。 这篇文章想说清楚一件反常识的事：通用 agent 越自动化，垂直场景的”原子...
AI 项目死在工程，不是模型
AI 项目不是败在模型，是败在工程——而工程的起点不是写代码，是定义 eval。 花了两周搭的 RAG Demo，演示会结束时所有人鼓掌。业务负责人跟 VP 握手，说这是”今年最激动人心的项目”。 三个月后，我打开后台看日活——零。 不是慢慢下滑到零，是从上线第二周起就一直是零。没人骂、没人投诉，只...
「AI 学得比我快吗？」——你可能问错了问题
上周有读者读完我”认知底座”那三篇，私信问我一个问题： “你说的这些道理我都认。但有件事我想不通——我花三小时想清楚一条 insight 的时候，模型可能已经爬了 100 万条新数据。我这么一周一周攒，到底图什么？” 这是整个系列讲完之后，留在最多人心里的那个终极怀疑。 我决定单开一篇讲清楚。因为如...
认知底座：AI + 传统行业从业者的第三种知识库方案
上一篇结尾我提到了第三种出发点——既不是 Karpathy 那种为研究者而生的”让知识积累成百科”，也不是范凯那种为创作者而生的”让知识变成内容产出”，而是：把一个陌生而复杂的行业，慢慢装进自己的脑子里。 有几个读者私信说，这一句话让他们突然对号入座。但更多的人问我：你说的这种”认知底座”，到底长什么样？跟前两...
Karpathy 的知识库方案很好，但它不是为你设计的
上一篇我介绍了 Karpathy 的个人知识库方法，不少读者照着搭了。但搭完之后，有人跟我说了一句话： “搭是搭好了，但不知道往里塞什么。” 这个困惑不是工具的问题，是一个更前置的问题没想清楚。
你收藏了 500 篇 AI 文章，却一篇都没用上——前 OpenAI 大神给出了真正的解法
前 OpenAI 联合创始人公开了他的个人知识库方法，20 分钟可以搭起来。 这个公众号不做 AI 搬运工。我每天只做一件事：在 AI 的喧嚣里，替你找到真正能用的东西。
Harness Engineering：拆开看看，哪些是新瓶装旧酒，哪些值得你真金白银投入
在 AI 的喧嚣里，替你找到真正能用的东西。不搬运新闻，不贩卖焦虑。 最近 Harness 这个词被聊得很多。2 月初 HashiCorp 创始人 Mitchell Hashimoto 率先在博客里提出了”Harness Engineering”的概念，2 月下旬 OpenAI 跟进发了工程博客，3 月...
