AI Builders 日报 — 6月7日

追踪 AI 领域真正在做事的人,而不是空谈者。

今日思考

两条线索指向同一个判断:vibe-coding 正在从玩具变成真正的生产力引擎。Replit 总裁 Michele Catasta 预计 2026 年底 AI 编程工具将具备"真正好用的 vibe-coding 工作马"所需的核心能力,瓶颈将变成"毅力"而非工具成熟度。与此同时,ex-Meta L8 工程师 Kun Chen 用 AI Agents 每天产出 40+ PRs——传统的代码审查和 merge gate 流程正在被 10 倍速输出撑破。工具在变,但工程流程的惯性才是真正的摩擦点。


产品与发布

Vercel AI Gateway

Vercel AI Gateway 每月平均恢复超过 1 万亿 tokens 的流量。CTO Guillermo Rauch 将其类比为 Stripe 的智能重试机制——在模型供应商之上叠加冗余、零数据保留审计、可观测性和用量上限,但不做任何加价。faviconx.com

Replit 生态信号

一位独立开发者在 90 天内用 Replit 做到 10 万美元 MRR。Amjad Masad(Replit CEO)评论:Replit 的核心哲学就是"移除一切干扰,让你专注市场化、专注搞钱"。三条经验:尽快上线(60% 就够了)、每天在社交媒体发帖、建立团队快速测试和增长。faviconx.com


观点与判断

Greg Brockman(OpenAI 联合创始人)

  • AI 能力的" overhang" 还很大 每当 Brockman 不用 codex 完成一项任务,他事后分析原因,通常是:缺上下文、该写一个 skill、或者根本没想起来用它。他很少发现任务超出了模型的能力边界。"Overhang 现在感觉很大。" faviconx.com

  • Codex 正在从助手进化成"AI teammate" Brockman 引述 OpenAI 公布的多个真实工作流:管理收件箱并用你的语气起草回复、PR 审查先于人工审查、Figma 设计转生产代码……覆盖软件工程、设计、数据分析和运营。 faviconx.com

Peter Yang(AI 编程播主)

  • Agentic coding 的上瘾程度超过电子游戏 "这种 agentic coding 的 crack 比电子游戏还让人上瘾," Peter Yang 在一条原创推文中写道,同条内容被 kunchenguid 本人转发。 faviconx.com

  • 传统工程流程是为每月 10-15 个 PR 的团队设计的 Kun Chen,ex-Meta L8 工程师,现在每天用 AI Agents 产出 40+ PRs。输出量增加 10 倍,传统流程(代码审查、merge gate、团队交接)开始断裂。解法:围绕规划、验证、审查和合并建立新系统,让流程去适应 Agent 的节奏,而不是让 Agent 迁就旧流程。 faviconx.com

  • Codex 线程管理需要更好的过滤机制 Peter Yang 提出产品建议:Codex 应该支持按状态(等待审批 / 工作中)过滤和排序所有线程,而不只是按项目分组。他自己在控制 10 个线程的情况下已经感到混乱。@ajambrosino 被点名。 faviconx.com

swyx(AI 工程播主)

  • Universal Basic AI:每人一股 xAI+OpenAI+Anthropic swyx 提出的政策设想:给每个美国公民分发一股 xAI、OpenAI 和 Anthropic 的股份。总成本约 6280 亿美元,相当于美国政府预算的 8.5%、国防预算的 62%,与金融危机时期的 TARP 救助计划规模相当——但这次是分散式分配,而非集中给大银行。 faviconx.com

  • 今年最大的代码评估发布明天登场 swyx 预告:一个重要代码评估项目的发布,他是议程定义的小时贡献者之一,并称这是"接下来 coding 关键阶段"的议题定义时刻。 faviconx.com

Garry Tan(Y Combinator 总裁)

  • 可复用智能让 Agent 不被代码框死 Garry Tan 评论:如果把智能工厂化,工人就无法做聪明的事。可复用智能意味着 Agent 不被硬编码逻辑约束——出了状况,它不会被代码围栏困住,它可以直接做该做的事。这与硬编码工作流和 UI 的范式转移有关:Agent 应该在运行时生成自己需要的逻辑和界面,基础设施保持确定性。 faviconx.com

We never said we don't upload any user data to the cloud. We said the code (file contents) specifically doesn't.

Paxel is here to help you, and over time as local models get better, we'll be able to do even more locally. Can't wait, tbh.

one popular theory is that research paper alpha* and lab publishing ~died when researchers realized that instead of fighting with marketing depts they could simply walk out the door and get >$100m for their legally protected tacit knowledge gained

california non-noncompetes have a bigger impact on knowledge spreading than github, arxiv, and huggingface combined

*btw this is a motivator for me to set up @aidotengineer as a product-centric industry conference to complement the paper-centric research conferences

roon: @beffjezos the sheer dollar quantity of ip leakage from openai has been just tremendous, probably in the trillions. openai truly has been quite open

Whenever I don’t use codex for a task, I ask myself why and usually realize that there’s some missing context, I needed to write a skill, or I just didn’t think to use it.

Rarely is it because the task is outside of the capabilities of the model. Overhang right now feels large.

idea - universal basic ai:

1 share of xai, oai, and ant to each US citizen.

cost
SpaceXai: $135.00 × 349 million = $47B
OpenAI: $733.54 × 349 million = $256B
Anthropic: $930.45 × 349 million = $325B

total $628B cost is 8.5% of US Govt budget, 62% of defense budget, roughly same as ~$700B of TARP program during the Financial Crisis (mostly given to big banks, this would be a lot more decentralized)

There should be a way to filter or sort all my Codex threads in different ways vs. only by project.

Like filter or sort by:

- All waiting for approval
- All currently working

I'm trying to keep it to 10 threads but it's already getting unwieldly. wdyt @ajambrosino ?

okay i'm just gonna share this..
*that's part of workflow how i automated my solo marketing agency
been using this free repo for a few weeks. ships in hours what used to take days
23 ready skills. product → design → QA → docs
an 18-year-old won a hackathon with this repo last month. in 2 hours
while 80 others were still figuring out what to build (cheat code for planning)
made by @garrytan (president of YC). 108k stars. you probably haven't found it
[ what blew my mind ]:
the setup takes 3 commands.. not 3 days
> 23 structured skills covering every phase: think → plan → build → ship
> /office-hours - YC-style review before you write a line of code
> /plan-eng-review - full architecture from one product decision
> /design-shotgun - 4-6 design variants in parallel, opens in your browser
> /qa - opens a real browser and clicks through your flows. finds bugs in the running product
> GBrain - persistent memory between sessions. the agent never forgets again
[ how i'm using it ]:
i run a fully automated marketing agency. solo. zero employees
gstack handles a lot of what used to need 5 hires:
> /office-hours scopes client launches in 5 min instead of 30
> /design-shotgun ships 6 landing page variants in one session
> /qa catches broken automation flows before clients see them
> /document-release keeps client deliverables updated automatically
> GBrain remembers every client's voice + history across sessions
what used to eat my mornings now finishes in an hour
[ the part nobody's talking about ]:
most developers using Claude Code are leaving 80% of its potential on the table.. they treat it like autocomplete
gstack treats it like a development system. product thinking, architecture, design, QA, docs - all passed between phases automatically
you stop re-explaining context every step
[ and the craziest part ]:
Rakhatbek (the kid who won) said it would have been "practically impossible to build a game like this in 1 hour 45 minutes manually"
3 commands. 1 markdown file. 23 skills
most developers will never install it.. not because it's hard, but because they think it's just another tutorial

"AGI for vibe-coding is coming earlier than 2028" says Michele Catasta (@pirroh) President of Replit (@Replit):
"I would expect by the end of 2026, a lot of the core functionalities that models and agents have to have, in order to become very good vibe coding workhorses, will be there".
"Literally the bottleneck would become grit, determination, if you want to take the time and, you know, invest a bit of money to make it happen".
"No vibe coding tool today is absolutely perfect... but the amount of creativity that they unleash is second to none."
From @pirroh appearance in March.

Yes, if you build a foxconn factory for intelligence, the workers can't do smart things

Reusable intelligence means the agents are not boxed. Something bad happens? it's not hemmed in by code. It can just do the right thing.

Spock Woz: @alphabatcher i mostly agree.

the bigger shift isn't markdown skills replacing code. it's moving from hardcoded workflows and UIs to reusable intelligence.

the agent should be able to generate the logic and interface it needs at runtime, while infrastructure stays deterministic underneath.

"If you're still manually reviewing every line of code, you're the bottleneck."
Here's my new episode with @kunchenguid, an ex-Meta L8 engineer who now ships up to 40 PRs a day with AI agents. Instead of manually reviewing code, he built an agentic engineering system that includes:
✅ Lavish, his free tool for annotating AI's plans as visual HTML artifacts
✅ gnhf or "good night, have fun," his free orchestrator to get agents working towards a goal while you sleep
✅ No Mistakes, his free AI code validation pipeline for catching errors before merge
Some quotes from Kun:
"If I spend a lot of time crafting detailed plans, then the agents can work for much longer."
"Every time I encounter friction in my workflow and I don't find an existing tool that can solve the problem, I just build something myself."
"To really scale how much we can get from the agents, we have to move ourselves out of the loop as much as possible."

Gbrain by @garrytan is so good, I've now moved by brain onto a dedicated server, that Codex, Claude, OpenClaw, and Hermes all connect to.
My agent conversations (and planning in particular) are so much more enriched and opinionated.
Every experiment I run in Codex uploads a summary and conclusion, so our mutual thinking continues to compound.

Ideally you want to be dismissed as being on the right by people on the far left and dismissed as being on the left by people on the far right. This is not a sufficient condition for getting things right (choosing positions randomly would achieve it too) but it's a necessary one.

A top 0.1% power user + the CEO on stage together!
- Why our AI Agents really work so well
- When an AI Agent can beat a human, and why
- How Replit combines models
- Why your second and third AI Agent will be better
- Why every company will end up with internal AI "Oracles"
- How monorepos are a secret unlock to agent performance

Most engineering processes were built for teams shipping 10 to 15 PRs a month.

@kunchenguid, ex-Meta L8 engineer, is now shipping 40+ PRs a day with agents. That breaks a lot of existing processes behind:

→ Code review & QA
→ Merge gates and team handoffs

When output jumps 10x, the old workflows starts to crack.

The answer is to build systems that streamline planning, validation, review, and merging as much as possible.

Vercel AI Gateway recovers on average over 1T tokens a month 🤯

Much like Stripe recovers revenue with smart retries on failed payments or credit card updates.

And we do it with 0️⃣ zero markup over the labs; adding redundancy, zero-data retention enforcement, observability, usage APIs, caps, …

beyond model size, the more interesting frontier is a thin layer on top: a coding agent that writes an executable world model, checks it against observations, and compresses it toward the *simplest program that fits.
it rides every base-model gain for free. A new s-curve sitting on the bitter lesson
*"simplest program" is what ARC-AGI measures in "skill-acquisition efficiency"
