We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics. The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra. The problem concerns whether the description of smooth three-dimensional fluid motion modeled by the Navier-Stokes equations can break down. It has remained unresolved for roughly 90 years.

“学会构建一个属于你自己的 Harness，朋友们。” https://t.co/2C2ux6EgXj 创始人 @omarsar0 这句大白话，直接把今年硅谷一线构建者心照不宣的最大底牌，彻底摊在了桌面上。 为什么今年 YC 几乎所有的软件创业团队，全都在疯了一样构建“特定领域的 Harness”？ 因为过去两年血淋淋的教训已经证明了： 靠给 API 套个精美界面的 Wrapper 工具，在大模型迭代面前脆弱得不堪一击—— OpenAI 或 Anthropic 每发一次新版，这种产品就要死一批。 真正能在 Agent 时代拥有绝对定价权的，从来不是模型本身，而是包在模型外面的那套专属 Harness（驾驭装置）： 1️⃣ 从产品维度看：它重构了用户的交互视界面： 大模型是无状态的、失忆的、缺乏常识的； 而一个成熟的 Harness，负责把你们行业最脏的业务逻辑封装成框架—— 工具怎么动态路由？长任务断点怎么续传？跨周的行业上下文怎么精准装载？ 它让用户面对的不再是一个需要费劲教它做人的空盒子，而是一座开箱即用的专业工作台； 2️⃣ 从技术维度看：它才是你真正的私有资产： 通用大模型只是一个租来的通用发动机， 但面对法律、医疗、金融、供应链这些深水区， 什么时候该让它自主跑完？碰到了不可逆操作怎么强制弹窗审批？错了一步怎么从快照回滚？ 这套把领域最佳实践与安全红线写死成工程代码的脚手架，大厂用再多通用算力也买不走； 3️⃣ 为什么这是不可逆的浪潮？ 正如 Garry Tan 之前那句冷血的判词： 旧软件要么作为记录系统（System of Record）老死，要么进化成领域专属的 Harness。 会用模型已经不稀奇了， 懂得为自己的业务定制一套严丝合缝的 Harness，你才算真正拥有了属于自己的智能技术栈。 大模型的单点智力正在被迅速拉平并走向商品化； 与其天天焦虑哪家模型又刷榜了， 不如沉下心来，为你的垂直领域焊好那套谁也拆不走的专属底座。 Harness 的浪潮已经兵临城下， 把工具箱做深的人，才配在这场长跑里拿到最后的门票。

Learn to build a harness, folks. It's not surprising to me that so many YC builders want to build domain-specific harnesses. If you work long enough on a domain-specific problem, you quickly realize the opportunity. But you also realize how important that harness will be to stay competitive in the agentic era. From a product perspective, harnesses open up interesting new surface areas and experiences for the services/products you provide. From a technical perspective, harnesses are how you build and maintain a framework and set of best practices for how your users/customers interact with what you offer. Understanding how to build and design a harness means you can build much stronger intelligence stacks, given that you can customize it and understand the domain well. That's extremely valuable. It may not seem apparent yet, but a harness wave is coming. If you are getting started, give this list of harness papers to your agents and start upskilling: https://t.co/nOPcXIaITT If you are already a builder, try building one for your specific domain. It's a lot of fun, and you learn a lot of interesting things to enhance your current agentic tools.
