Dogfooding（内部试用） 应该被 AI 创业公司重视起来了。 对于今天的 AI 公司来说，「先解决自己的问题，完全可能带来改变整个市场的突破性产品。」 比如，Anthropic 今年推出的 Claude Code，就是这样的一个典型。与其他 AI Coding 产品不同的是，Claude Code 源自公司内部工具孵化，在经过高强度的 内部使用和真实使用场景验证之后，对外发布。 也正是因为从真实的用户需求角度出发，Claude Code 相比于其他产品，功能设计更能切中开发者的核心体验。所有交互都可以通过命令行完成、全局代 码库理解能力等等，这种独特的优势，加上背后强大的基础模型能力以及高性价比，让 Claude Code 仅在发布四个多月后，便拥有了 11 万开发者用户。 Claude Code 的成功或许说明了一点：深度、真实的内部试用是最终的、不可复制的竞争优势。最好的产品往往不是来自市场调研，而是来自于解决自己 每天面临的真实问题。 对于今天还在苦苦寻找 PMF 的 AI 初创公司来说，Dogfooding 很重要。 Gennaro Cuofano 最近的一篇博客文章，详细地介绍了 Claud ...

Manus 官网昨天更新了一篇文章，分享了他们为 Manus 搭建合适的上下文工程的经验教训。 作者季逸超 (Peak)，Manus 公司联合创始人、首席科学家。 文章基于 Kimi K2 翻译，我们进行了一些调整。 在 Manus 项目伊始，我和团队就面临一个关键抉择：是利用开源基础模型训练一个端到端的智能体，还是依托前沿模型的上下文学习能力，在其之上 构建智能体？ 在我投身 NLP 的第一个十年里，我们并没有这种奢侈的选择。遥想当年 BERT 问世（没错，那已是七年前），模型必须先经过微调——还要评估—— 才能迁移到新任务。每次迭代往往耗时数周，尽管那时的模型体积与今日的 LLMs 相比微不足道。对于快速迭代的应用，尤其是 PMF 之前的阶段，如 此缓慢的反馈循环几乎是致命的。这是我上一家初创公司留下的惨痛教训：当时我从零开始训练模型，用于开放信息抽取和语义搜索。随后 GPT-3 与 Flan-T5 横空出世，我那些自研模型一夜之间便失去了意义。颇具讽刺意味的是，正是这些新模型开启了上下文学习的大门——也为我们指明了一条全 新的道路。 这个来之不易的教训让选择变得清晰：Manus 将押注于上下文工程。这让 ...

程序员最有价值的技能已经不再是编写代码了，而是精确地向 AI 传达意图。 一份完善的规范才是包含完整意图的真正「源代码」。 这是 OpenAI 研究员 Sean Grove 在 AIEWF 2025 的演讲中提出的观点。前不久， Andrej Karpathy 也针对于提示词提出了他的观点 ，不同的是，Karpathy 聚焦如何给 AI「喂更多地料」，让 AI 更理解你的意图。Karpathy 认为，提供完整且恰当的上下文往往比编写好的提示词更重要。 Sean Grove 的视角则聚焦在如何形成一份完善、可执行的「规范」，以此精准地向 AI 传达意图。 在某种程度上，两者的观点都深刻地体现了一点：生成代码已经不是重点了，软件工程的本质是人与 AI 之间的「沟通」。 而且，这也可以看作是对 Jason Wei 提出的验证者规律 的回应，规范本身就是一种可验证的标准。 在演讲中，Sean Grove 从 AI 时代「新代码」的角度，分享了他对于软件工程的看法。Sean Grove 认为，提示词是规范，不应被用过一次后即被丢弃，捕 捉其中的意图和价值观非常重要， 最有价值的成果不是代码，而是源规范。 此外，Sean ...
