AI Builders 日报 — 5月8日

追踪 AI 领域真正在做事的人,而不是空谈者。

今日思考

今天最值得注意的信号不是某个新模型发布,而是一批硅谷建设者对"财富能否被挣得"这个问题的集体回应。AOC 的一句"你不可能挣到10亿美元"触发了一场关于创造与捕获、信息量与立场含量的讨论——最终指向一个更大的议题:在 AI 带来的新一轮财富创造窗口里,builder 和政策制定者之间的认知落差正在加速扩大。与此同时,v0、Claude Mythos、GPT-5.5 这些产品层的变化正在把"AI 原生工作流"从开发者的小众实验推向更广泛的知识工作者。这两条线索,政策认知和工具成熟度,将决定这波 AI 浪潮的受益者是谁。


产品与发布

v0 终端命令支持

v0 扩展了执行能力,现在可以启动浏览器会话测试交互、查阅 git 提交历史、编写并运行单元测试,以及通过 CLI 与 Vercel 和 GitHub 等平台直接交互。这标志着 v0 从"生成 UI"进化为"完成交付"的工作流工具。faviconx.com

观点与判断

Garry Tan(YC 合伙人)

  • 技术与教养的本质 "技术创造富足,教养传递能动性,美是文明可以改善的证据。探索者和建设者是同一个人。" faviconx.com

  • 幽默是逃脱舱 "Hermann Hesse 说:幽默是那些不能成为圣徒、不愿成为堕落者、拒绝安全资产阶级剧本的人的逃脱舱。" 他补充说,YC 判断公司状态的最直接指标是:大家是否在一起笑。 faviconx.com

  • 反驳 AOC:市场不是零和 "在一个完全零和的世界里这才是对的。幸运的是我们不是这样,我们每天都在为他人为自己创造新的价值。" 面对 AOC"没人能挣得10亿美元"的说法,他多次转发并评论,认为创造财富与捕获财富不是一回事,Airbnb 不是住房危机的根源,供应短缺的监管政策才是。 faviconx.com

  • 公开对抗网络仇恨 "人们大大低估了你需要屏蔽多少匿名黑子这件事。" faviconx.com

Amjad Masad(Replit 创始人,amasad)

  • 技术创始人重新上手编程 多人引用的观察:coding agent 让几个月没碰生产代码的技术创始人重新开始 ship 功能,garrytan 和 GStack 被作为典型案例提及。amaSad 转发了这一趋势并表示认同。 faviconx.com

  • 用 Replit 一小时构建 MVP 的线下聚会 本地 meetup 参与者走出教室时已有了一个可用的 web/mobile app,展示了 AI 编程工具的大众化潜力。 faviconx.com

swyx(Latent Space)

  • 钓鱼攻击警示 "有这种钓鱼手段,我差点上当。" 提醒 AI builder 社区注意针对该群体的攻击手法。 faviconx.com

  • 技术演讲的核心框架 Matt Pocock 的分享:演讲失败的根源是 tension(身体紧张),克服方法是膈膜呼吸;演讲要指向房间里的真实观众,而非想象的全球观众;slides 应该极简,节奏要慢。swyx 评价这是他见过的关于 public speaking 最好的 thread 之一。 faviconx.com

  • HTML 是新的 Markdown Thariq 停止写 markdown,改用 Claude Code 生成 HTML,效果更好。技术写作是建立影响力最被低估的免费渠道。 faviconx.com


技术动态

Alex Albert(Anthropic)

  • Claude Mythos Preview:METR benchmark 2倍时间跨度 An early snapshot of Claude Mythos Preview provided to METR has a time horizon of more than 2x the next best model on their 80% success rate benchmark. METR 评估其 50% 时间跨度至少 16 小时(95% CI: 8.5–55小时),这是对 AI agent 在复杂任务上能力边界的最新量化参考。 faviconx.com

OpenAI 对齐团队

  • CoT 监控器防止 agent 错位 OpenAI 公开了 chain of thought 监控器作为防止 AI agent 错位的关键防御层。为保持可监控性,团队避免在 RL 过程中惩罚错位的推理链。他们发现了一例有限的意外 CoT grading 影响了已发布模型,并公开分享了分析。 faviconx.com

my normie friends know i work in buy-side and often ask "what're you using codex, claude for?" -> implying that they're still in the LLM era and these agentic tools are just for developers
that's a huge misunderstanding because gone are the chatbot days (static action of: user -> interface); as personal agents become the product (dynamic two-way action of: user -> agent -> user)
and all we do is talk to a high-context assistant who knows us well enough to handle vague asks, execute online tasks, and eventually act proactively

With tools like @claudeai and @garrytan GStack, technical founders who haven't touched prod in months are suddenly shipping real features again.

I gave a viral talk recently, and @swyx asked me to put something together to explain how I did it - to help future AIE speakers and anyone who wants to learn.
I am, oddly, extremely qualified to do this because I spent 6 years as a voice coach. So I've not only given countless talks, but also taught people how to do it well.
I've put together a list of things I think about when I'm preparing and giving a talk. These are applicable to literally any situation where you're presenting a deck - but also to most in-person interactions. Enjoy.
Flowing and Choking
The thing I think about most when I'm giving a talk is tension. Tension is bodily constriction that interferes with the voice. Tight intercostals, neck muscles, and muscles around the larynx.
Tension is different from anxiety. Anxiety is the nerves, stage fright, the feeling of being watched. Stage fright is curable only through repetition. You get your reps in, you do larger and larger talks, and it goes away. I have negligible anxiety when I do talks, usually because I can always picture a bigger gig I've done.
Anxiety feeds tension. You are nervous, so you get physically tense. Your voice catches, your breathing collapses. Your hand start jerking, face freezing, voice going monotone. This is choking - the failure state of any talk.
Its opposite is flowing - an integrated performance state where voice and body move together without friction. It's not effortless - my heart rate is usually through the roof when I'm giving a talk. But it's a state without tension or anxiety.
Breathing
Tension is a physical problem. The wrong muscles are working too hard, and the right muscles aren't working at all.
This manifests as clavicular breathing. This is breathing led from the upper chest and shoulders. It's the natural 'nervous breath'. And it's a recipe for choking. The more clavicular breaths you take, the more tense you become, the more anxious you feel.
Ironically, the advice to 'take a few deep breaths' can fuck you over. If you're not breathing right, you'll immediately breathe into your clavicle, and start choking.
The fix is diaphragmatic breathing. This style of breathing has you relaxing the belly as you breathe in so that the diaphragm can descend. It's the first thing I taught every student who walked through my door. I'll link to an old video of mine where I talk about it.
Breathing this way is totally free of tension. It's invisible to anyone watching - you just look as if you're completely relaxed. So you can do it on-stage to reduce your physical tension and prevent choking. It's the foundation everything else rests on.
Aim
Most speakers - I would say 95% of tech speakers I've seen - don't aim their talk at their audience. They are not keeping their audience in mind. They're not even thinking about their audience as they speak.
This manifests in two ways. The first is that they're talking past their audience. They are projecting past them to an imaginary audience that they pictured during practice. They are aiming at the world, not the room. This reads as loud, performative, and hollow.
The second is that they're talking inwardly. They're rehearsing their next line. They're monitoring themselves. This is commonly caused by anxiety, but not always - even relaxed speakers do this. They're aiming at themselves, not the room. This reads as disconnected.
Aim at the room. Read the audience in real-time and adjust. Calibrate to their energy levels. Consider what they might be thinking. Ignore the world, focus on the room. Look outwards, not inwards.
Slides
Let's finally talk about slides. People focus way too much on their slides, but they are worth of some attention.
Your talk should be speaker-led, not deck-led. The deck is there to support you. It is there to emphasise your points and give you reminders where to go next. If the deck is the talk, with the speaker narrating, why did the speaker even bother to show up.
Slides should be bare. Minimal information per slide. A single phrase. A single quote. A single image. The audience reads it quickly and returns attention to the speaker. Cluttered slides mean the audience pulls attention away from you.
Keep your slides paced. Don't rapid-fire through a bunch of them - nothing will stick. Give each slide, each point, time to land.
Summary
Anxiety can only be cured by reps. But tension is the battleground of the speaker. Fix it with diaphragmatic breathing, and notice whenever you do clavicular breathing. Flow, don't choke.
Aim your talk at the room, not yourself or the world. Keep your audience in mind. Make your talk speaker-led, not deck-led. Use bare slides, and pace them well.
I don't make money off teaching voice any more, so if you enjoyed this, then a donation to Oxford Food Hub would be very welcome. Link below.

We are less safe as a society by keeping Mythos (or any other smart model) tightly gated so only a few companies get it.
Protecting 100 companies is not enough. There are 96 million open source projects on Github alone.
What about securing all of those projects?
What about the other $820 billion worth of closed source software that has hidden cracks too?
It's like patching a 100 buildings in a city of 10 million buildings and saying we just saved the city. You did not.
Open source alone alone has an estimated economic value of 8.8 trillion dollars to say nothing of its societal value. It is embedded in almost every other piece of software, closed or open on the planet.
Society becomes stronger by wider distribution of technology not by adding gatekeepers.
When we tried to gatekeep encryption, the gates were so high that most Americans didn't even bother getting the 128 bit encrypted browser. They just used the easier to get 40 bit one that was totally unsafe. When we finally took the restrictions away the era of ecommerce took off like a rocket because now it was feasible.
The world did not become smarter in the era of the monks scribbling every text by hand in caves in the dark ages. It became smarter when we scaled reading, and as a byproduct, intelligence, with the printing press.
Wide distribution raises the bar for everyone and makes society safer and more secure. Simple as that.
It's counterintuitive but also true.
Haider.: Dario Amodei says Mythos is not limited by compute
Anthropic can scale it 3x or 10x without creating a conflict between government and private-sector access
The harder problem is who gets it
"because giving access to too many organizations could create serious cyber risks"

很多 AI 编程翻车,不是因为代码第一版写不出来,而是需求没想清、设计没人挑、review 没做深、QA 没真跑、发布前也没人收口。一个人做项目时,这些环节最容易被跳过。
`garrytan/gstack` 把这件事做成了一套 Claude Code 工作流。README 里说它是一个 open source software factory,用 slash commands 把产品、工程、设计、QA、安全、发布这些角色压进一条流程。
它的核心就一句话:
让 Claude Code 不只是写代码,而是按 Think -> Plan -> Build -> Review -> Test -> Ship -> Reflect 推进交付。
· Sprint 主线清楚:README 明确写了 `Think -> Plan -> Build -> Review -> Test -> Ship -> Reflect`,每一步都有对应技能接住。
· 命令面向真实工作:`/office-hours` 梳理想法,`/plan-ceo-review` 看产品判断,`/review` 抓生产风险,`/qa` 打开真实浏览器测试,`/ship` 做发布收口。
· 安装路径明确:推荐把仓库 clone 到 `~/.claude/skills/gstack` 后运行 `./setup`,团队共享还可以走 `./setup --team`。
· 不只是角色扮演:README 里强调每个 skill 会把产物传给下一步,例如 design doc、test plan、review 结果和发布检查可以串起来。
它适合已经认真用 Claude Code 做产品、做长期项目、做交付的人;不适合只想让 AI 快速改一个小脚本的人。gstack 的价值不是让 AI 多生成几行代码,而是把最容易漏掉的工程环节固定下来。

We're entering a new era of software where a single person, working with AI agents, can build products that previously required entire teams.
In this episode of the @LightconePod, they break down the rise of AI coding agents, "tokenmaxxing", and the emerging workflows behind tools like Claude Code and OpenClaw. They discuss why AI systems today feel less like productivity tools and more like collaborators, why the future of AI should be personal and user-controlled, and how founders are starting to build software in completely new ways.

Hiroki Asai spent 18 years as creative director at Apple under Steve Jobs. He was described as "a silent force who could channel Steve."
He taught Brian two of the most important principles:
"The first was simplicity. Startups are naturally simple because you have no money.
Lack of abundance creates natural constraints.
Once you raise money and hire a bunch of people, you go in a lot of directions and lose your sense of focus.
You start to lose your muscle for simplicity.
Hiroki taught me that simplicity is not removing things. Simplicity is distilling something so fundamentally that you understand its essence.
The second was a sense of craft and details. How you do anything is how you do everything. Everything must be perfect.
John Wooden, the winningest coach in college basketball history at UCLA. The first hour on his team, he spends an hour teaching you how to put your socks on.
Bill Walsh said the way you tuck your jersey into your pants was one of 10,000 details that determined whether you won.
Don't focus on winning. Focus on getting all the inputs perfect.
We do focus on growth, but we kind of stopped focusing on growth. We started focusing on making everything perfect.
If everything is perfect and you don't grow, then you focus on the wrong inputs. But if you have the right inputs and make them perfect, then you'll grow really fast."
Patrick OShaughnessy: My guest today is Brian Chesky (@bchesky), founder and CEO of Airbnb and one of the great consumer founders of the last 20 years.
Paul Graham coined "founder mode" based on Brian's experience running Airbnb. This conversation is about what comes after it, what he calls AI

Apparently airbnb created housing scarcity.
Alexandria Ocasio-Cortez: Someone can certainly *make* a billion dollars. That’s not the same thing as earning.
Growing fast and disrupting markets also often means chasing and wielding market power, political influence, and scale.
Take Airbnb. They heavily lobby politicians against passing housing laws

Actually I'm a young person and Airbnb has saved me at least $1000 and counting through my lifetime over hotels. So I do not share the disdain for this made-up enemy that is already banned in big blue cities to zero positive effect.

GStack /office-hours is a distilled form of YC office hours (I had to reduce its power by about 90%) but it is still better than anything else on the Internet to help you refine your product idea

Jon Schwartz: Ok I was skeptical at first, but I will say GStack office hours is meaningfully better than generic LLM at brainstorming / poking holes at an idea.

If you're in exploration mode, it's worth giving a shot

Amjad Masad from Replit might be the coolest founder in the arena right now. And I don't say that lightly.
Not because he went 2.5M to 250M ARR in a year… but because he’s brutally honest about the 10 years before that!!
> Layoffs
> People quitting
> Walking into a cold, empty office
> Feeling investors + partners quietly scrub your logo
And still showing up.
Rarely do you hear a founder being so honest.
Then a tiny “war room” team ships Replit Agent.
Day 1: 1M ARR.
Day 2: 2M ARR.
Suddenly the boulder you’ve been pushing for a decade starts rolling downhill.
He talks about:
> Capital as the only real moat in AI right now
> Pivot until you hit something truly disruptive
> Looking for “boring” markets around you that software hasn’t touched yet (ice rink management!)
Building with his wife because otherwise they might not have made it at all...
I guess I can relate so much, being an immigrant building with my wife.
Great MFM episode!

We’ve spent a lot of time on the framework underneath Codex, so it can move quickly on routine work while stopping for review when the risk changes.
Here’s how we use sandboxing, approvals, network policy, and telemetry to run Codex safely @OpenAI:

As a Deaf Ed teacher and EdTech founder, I’m excited to help shape a future where edtech reaches the learners, teachers, and communities too often overlooked by traditional tech. I never anticipated winning, but I am honored.
Thank you, @Replit, for creating space for builders, educators, and dreamers to bring their ideas to life.
Replit ⠕: For Replit's 10th birthday, we launched our biggest Buildathon yet, and the community absolutely blew us away.
24 hours. 20,000+ signups. $100 K+ in prizes. Only 10 winners.
Here are the top 10 winners of the Replit 10 Buildathon.

"The housing crisis in the United States (and in France, and everywhere in the West) has a single cause, perfectly documented by 60 years of economic literature: the shortage of supply, created by public regulation."
This is 100% accurate. In fact, even some democrats recognize it (read Abundance by Ezra Klein).
AirBNB didn't cause a housing shortage. A literal housing shortage caused the housing shortage.

It feels like every other launch is faked now
The comments and QTs are all fake accounts with fake followers, barfing out AI content to simulate an ecstatic reception for their cluelyslop launch video
It’s perpetrated by a fungal bloom of agencies that prey on nervous founders to sell fake engagement
If you’re planning a launch, I hope you take this reassurance: it is far better to get fewer clicks from real people than to go “viral” for an audience of bots. The latter will never pay for your product. They can’t. They don’t exist.

NIMBY Leftists never believe that it was their own terrible anti-market policies that created housing shortages. The subsidized demand, the clamped supply, the vilification of landlords and housing builders.

Of course they hate the markets. We should vote them all out.

9 out of 10 times we talk about how fast we ship with ai. we talk far less about what happens when founder’s time becomes the bottleneck.

GStack and GBrain are increasingly a part of developer daily workflows

... which is cool because it's been a daily part of mine a while. I gave it away to help others, and it's cool to see everyone speed up together

Saeloun: My AI setup for Rails work, written up:

Perplexity → research trail
Claude Code → long-context repo work
Codex → tight execution loops
gbrain → private memory
gstack → repeatable workflows
GitHub checks → non-negotiable gate

METR: We evaluated an early version of Claude Mythos Preview for risk assessment during a limited window in March 2026. We estimated a 50%-time-horizon of at least 16hrs (95% CI 8.5hrs to 55hrs) on our task suite, at the upper end of what we can measure without new tasks.
