AI Builders 日报 — 4月27日

追踪 AI 领域真正在做事的人,而不是空谈者。

今日思考

今天的信号很清晰:AI 正在从"工具"进化为"代理人"。两条推文指向同一个方向——Sam Altman 宣布 OpenAI 与微软的合作升级为多云架构,Avoca AI 刚融资 $125M 估值 $1B,专做蓝领服务经济( HVAC 、水管、屋顶)的 AI Agent。这意味着 Agent 的战场已经从开发者的工作台扩展到了现实世界的每一个服务场景。而 Demis Hassabis 在 YC 的闭门会上预测 AGI 2030 到来的背景音,让这个叙事多了一层紧迫感:基础设施层(模型)和应用层(Agent)都在加速,留给"慢慢来"的时间不多了。

观点与判断

Sam Altman(OpenAI CEO)

  • OpenAI 与微软合作重大升级 微软继续保持主要云合作伙伴地位,但 OpenAI 现在可以在所有云上提供服务。模型和产品供应延续至 2032 年,收入分成至 2030 年。faviconx.com

Demis Hassabis(Google DeepMind CEO)

  • AGI 2030 年到来 在 YC 闭门会上表示,AI Agent 是未来(6-12 个月后,一个小孩就能 vibe-code 出 $10M 产品),每个任务本质上都是编码任务。Deep Tech 是真正的护城河,AI Wrapper 没有壁垒。faviconx.com

Paul Graham(Y Combinator 联合创始人)

  • 不必担心被模型公司吃掉 "担心你的创业公司被模型公司吞掉,就像担心你成为电影明星之后生活会受限制一样。你更可能只是直接失败。"faviconx.com

Garry Tan(Y Combinator 总裁)

  • 打造一个会说话 Agent 的秘密不是一份文件,是三份 SOUL.md 是 Agent 的宪法(规定 voice 和 operating principles),USER.md 是你的深度模型(4000 字描述你的思维和工作方式),AGENTS.md 是操作手册。"Generic instructions → generic output." 要写出"活的" Agent,就要把指令写得残暴具体。faviconx.com

Aaron Levie(Box CEO)

  • AI 消除工作恐慌被夸大 我们对 AI 替代自己工作的难度有深刻体感(访问数据、建立上下文、审核输出、融入业务流程),但看到别人工作时又觉得 AI 能立即自动化那个领域。"Gell-man amnesia"——双重标准,根源是低估了"最后一公里"的工作量。faviconx.com

Anish Acharya(金融科技投资人)

  • Agent 将系统性瓦解"可利用的消费者惰性" 消费金融的利润来源是信息不对称和消费者不作为:滞纳金、试用期利率、透支费。AI Agent 会逐一规避这些成本,仅把储户从高息债务转移到低息债务(他们已有资格!),每年就能为美国家庭节省数千美元。这将摧毁大量消费金融公司的利润池。faviconx.com

Rory O'Driscoll(Scale Venture Partners)

  • Rippling 年化收入突破 $1B 增长 78% SaaS 已死的反驳 Payroll 是无法 vibe coding 的领域——法律义务带刑事后果,没有人愿意把不确定性引入薪酬计算。"AI 改变的是软件如何构建,而不是人们为什么付钱。"faviconx.com

Peter Yang(AI 科技博主)

  • Solo AI 创始人 tibo_maker 月收入 $1M+ 的 5 条忠告 ①第一天就收钱(免费注册不是 traction);②用户行为出乎意料时就跟着信号走(tibo 把 $2K MRR 的工具转向视频赛道做出 $600K+ MRR 的 Revid);③AI SaaS 定价 $50-100/月最合理;④月度流失率超过 20% 就先停增长修产品;⑤用工具页面做 SEO(Revid 有 100+ 页面对应具体 Google 搜索词)。faviconx.com

Daniel Jeffries(AI 安全评论员)

  • AI 是历史上最安全的技术推广之一 全球数十亿人使用,出问题比例低于割草机。比核能更安全(核有多次重大事故,AI 没有)。自动驾驶 Waymo 比人类安全约 10 倍。"对 AI 危险的恐惧之所以持续存在,是因为现实中根本没有实际伤害发生。"faviconx.com

Yann LeCun(Meta 首席 AI 科学家)

  • 美国政府解散国家科学委员会是摧毁 80 年科技积累 对 Science Board 的无解释解散,是在fantasy dystopia 中想象科学运作方式的人做出的决定。faviconx.com

ID_AA_Carmack(Armada CEO / 连续创业者)

  • 交互反馈延迟决定体验成败 在游轮上观察 10 部圆形 elevator 的使用:人们按下目标楼层后习惯性移开视线,而电梯需要 2 秒才能完全稳定。"交互反馈延迟"——按钮按下后字母提示应该瞬间出现,而不是渐入动画。更好方案是同时发出本地化音频提示。faviconx.com

技术动态

gdb(AI 工程师)

  • GPT-5.5 擅长写 GPU 内核 GPT-5.5 在 KernelBench-Hard 任务上表现优秀,gpt-5.5 在困难任务上比 5.4 快 2-5 倍。faviconx.com

Garry Tan(GStack CEO)

  • Graph + Vector 联合检索才是正解 纯 Vector 检索不够,需要 Graph + Keyword + Vector 三者协同。"stale context 是 silent eval killer"——写入时重新嵌入(re-embed-on-write)被低估了。faviconx.com

Glad to see this is now resolved.. Anthropic is going to issue refunds and free credits to all Hermes users or people who've used claude code to help develop Hermes Agent.
A bit frustrating to keep seeing these kinds of things happen but, hopefully they make it right for all of you.
I however haven't used claude code in months and only use hermes agent, so to compensate me they should give me access to mythos right now xD

Noticing an interesting version of gell-man amnesia where people use AI for their job and see all the various things they have to do in the “last mile”, but then look at someone else’s job and think that AI will eliminate it immediately.
We all have a much deeper appreciation for the nuances and complexities of the work that we do every day. We run into issues about accessing data, we know how much context is needed to get AI models to work the way we need, we have to review the output of the AI to make sure it’s accurate, and then we have to incorporate that work into some broader business process. We see all those steps deeply for the work that we do.
Then, a moment later, we see AI do something in a foreign space and think that it can go automate that entire function. We tend to dramatically underestimate the work that goes into making the AI work just as effectively in those jobs.
This is reason to be skeptical about many of the theories of job loss. It’s coming from the lens of being able to automate individual tasks with AI, without understanding all the work that goes into doing the job fully.
Karri Saarinen: A common dynamic I observe with AI: it feels most impressive when you don’t know much about the subject, don’t care or don’t have a clear idea of what the you want.
This applies across design, code, legal, and more. If I don’t know code very well, every piece of code it writes

Graph, and vector have to work together to get you better retrieval.

I realize this is not rocket surgery or new ground— but for it to work out of box with OpenClaw as a Karpathy knowledge wiki synced off a git repo is somewhat useful, and is exactly what I needed for myself

hanzi: @garrytan this matches what i keep seeing in agent/RAG work: graph, keyword, and vector fail in different ways, so the product win is orchestration + evals, not one retrieval trick. re-embed-on-write is underrated too; stale context is the silent eval killer.

又来了,YC的CEO Garry Tan又又又开源了一个东西——
这次直接把"浏览器"塞进了Claude Code里,Cmd+一行指令,AI就能和你并排操作Chrome了🤯
卧槽,这玩意你受得了吗
给兄弟们介绍一下,Garry Tan,Y Combinator现任CEO,全世界最懂早期创业那批人
他手里这家孵化器,过去二十年喂出来的公司——Airbnb、Stripe、Reddit、Coinbase、Doordash——估计你每天都在用其中至少三家
他这次又在干嘛?
他原话就一句话——"Did you ever want to control your browser side-by-side with Claude Code?" 翻译成人话就是:
你有没有想过,让Claude Code直接接管你的Chrome,跟你坐一张桌子一起干活?
然后他甩出来两个东西:
/open-gstack-browser skill——一个Claude Code 原生 skill
GStack Browser——一个为AI优化过的浏览器封装
装上以后,你在终端里给Claude Code下个指令,它能直接打开你浏览器、点按钮、填表单、抓页面——但你自己也能同时操作那个窗口
不是接管你的鼠标键盘,是真的"side-by-side",AI一边干,你一边盯
最反认知的地方在这里,市面上做computer use的玩家都是OpenAI、Anthropic、Google这种万亿级巨头——大家默认这是底层模型公司才能玩的东西,因为要训专门的vision模型去识别像素级UI元素。
但Garry Tan用一个 Claude Code skill 就把"浏览器并排操作"这件事给做出来了
没训模型,没烧GPU,就用Claude本身的视觉+工具调用能力,包了一层薄到不能再薄的封装
最狠的是,他根本不收钱,太夸张了
我们之前总以为,computer use这种"AI直接帮你操作电脑"的能力——只有训得起百亿参数视觉模型的公司才配玩
直到看完Garry Tan这个 skill 我才反应过来——
早不是这样了:最强的模型已经训完了,剩下的差距,全在怎么把它们拼起来用
以前你做一个AI帮你订机票的产品,得自己训模型、自己搭后端、自己设计prompt、自己处理浏览器自动化——
一年时间、几百万美金、十个工程师起步
现在Garry Tan写了不到一个 skill 的代码量,YC的CEO直接把这件事做成了开源工具,免费扔给全世界。
这他么才是2026年最值得被记住的一句话——
「未来十年最值钱的,不是训模型的人,是把模型组装成产品的人。」
而且最讽刺的地方就在,连YC的老板自己都在亲手干这件"组装"的活儿——他不是在投这种公司,他自己就是这种公司。
你还在等什么?
skill安装命令评论区放了,一句话搞定👇 2026年,能不能跑得过别人,就看你这个月装了多少个 skill 了
共勉了家人们
Garry Tan: Did you ever want to control your browser side-by-side with Claude Code? Now, with /open-gstack-browser skill and GStack Browser, you can

The secret to an articulate agent like mine isn't one file. It's three:

SOUL.md — Who the agent IS. Voice, values, operating principles, what good output looks like, what bad output looks like. Not a system prompt, a constitution. Mine says things like "brevity is mandatory," "humor is mandatory," "never open with 'Great question,'" "swearing is allowed when it lands." The more specific and opinionated this is, the less your agent sounds like a chatbot. Write it like you're briefing your smartest friend on how to be you, not like you're configuring software.

USER.md — Who YOU are. Not a bio — a deep model. How your mind works, what you're building, your strengths, your blind spots, your family, your temperament, what triggers you, what you care about. The more the agent understands about you, the better it can serve you. Mine is ~4000 words.

AGENTS.md — Operational rules. What to check on every message, what to never do, how to handle failures, lookup chains, path rules, brain-first protocols. This is the playbook for how it works, not who it is.

The articulation comes from SOUL.md being brutally specific about voice. Generic instructions → generic output. If you write "be helpful and concise" you get ChatGPT. If you write "speak like a peer with taste, one sentence when one sentence works, uncomfortable truths welcome if actually true, language with voltage" — you get something alive.

Soham Naran: @garrytan Can you share your agent.md?

You're agent is really articulate.

AI has had one safest technology roll-outs in history.
Read that again, because it's a fact.
It's used by billions with a tiny fraction of a percent of actual problems.
And yet it's seen as dangerous or unsafe by many.
There's a constant chorus of people shouting about its supposed dangers with no evidence whatsoever where it matters most: here, in the real world.
So what do we actually have here in reality?
A few cases in courts about early versions of ChatGPT allegedly being too sycophantic and not recognizing mental illness or someone in trouble, that are still making their way through courts and may prove wrong or right (some of the media released snippets are damning but not definitive).
Time will tell. Innocent until proven guilty. The very nature of court litigation is often to find a scapegoat for something that gets thrown out in the actual process of the trial.
But outside of that, what?
Answer: not much.
And viewed through the lens of other technology in history its incident rate is probably lower than lawnmowers.
It makes little sense when you think of it through the lens of other tech like cars and planes, which had atrocious early track records.
AI even has a better track record of safety than nuclear.
Despite being incredibly safe overall, nuclear had several high profile and dangerous failures with Three Mile Island and Fukishima.
With AI, nothing of the sort. Not even remotely.
I can hear the naysayers now saying "so far, but just you wait!"
And yet we keep waiting. And waiting. And waiting.
AI fear is a remarkably resilient beast.
It's resilient despite zero actual harms manifesting here in reality land.
Self-driving cars are remarkably safer than humans who kill 1.2 million people and injure 50 million more each year world wide. (I wrote 1.5M in an early posted and missed my typo).
Waymo cars are roughly 10X safer than humans with minimal injuries and fatalities. Even early self-driving cars had incredibly good safety records vis-a-vis early cars driven by humans that had bad safety records even up through the 1950s and 60s.
When it comes to cars, society actually resisted making them safer. People fought having to wear seatbelts because they had to pay for them. They resisted early drunk driving laws as impingements on their freedom.
Early plane travels was incredibly dangerous. It took many many decades of work to make them the marvels of safety they are today.
What about jobs?
We have AI execs talking about the "end of work" and yet they're hiring more people in the very profession that is supposedly most exposed: programming. Often at super high salaries approaching half a million dollars a year.
Demand for good programmers is rising.
We've certainly had execs claim they let people go because of AI. But a deeper look at these claims quickly reveals that most of them are just an easy way to get around labor laws or to simp to shareholders and more readily attributable to COVID over hiring. Tell shareholders "AI" is the reason for layoffs and you're rewarded for being more "efficient." Tell them you have to lay people off because you over hired or just made mistakes and your stock gets hammered.
The truth is that anyone who uses AI seriously at the frontier sees how much they have to baby sit it and hand hold it and steer it. It is not doing any job end to end. It's doing tasks and that is about it.
Now it will certainly get better but will it magically make the leap from task to job? Maybe. But we'll need evidence of that in, you guessed it, reality before we start making policy decisions.
So what other problems do we have here in reality?
Nothing but the two problems I've already discussed at length in my work:
Surveillance and weapons of war.
But these are not new. They're just things that AI enhances, just like computers enhanced them, and better materials science, and many other tech revolutions before them.
Again, ask yourself, really ask yourself, where are the real problems?
And again, there's a loud chorus of people who keep shouting "just you wait, I imagined this problem in my head and it's totally inevitable because I say so" and yet billions of people are using this technology every day with no problems.
Now you could say "Russell's Turkey." The trend is the trend until it breaks. But then the burden is on you to prove the trend is breaking. There is no evidence of it other than in people's minds.
At what point do people just wake up and realize that none of this makes any sense?
It's not that there won't be problems. It's just that often times the problems we imagine (we've been imagining the end of all work for 100 years) don't match what happens in actual reality. The problems turn out to be very different and you can only deal with them when they come up.
A lot of politicians today imagined if they had only "gotten ahead" of the Internet with regulations we'd be in a much better place.
Utter nonsense. When Section 230 was passed the number one question among Congress was "what is the Internet?" And these folks are supposed to imagine TikTok 25 years later?
No.
We have to deal with problems as they come up, not imaginary problems that some very vocal people promise are coming. The burden is on them to prove it and writing long essays from "first principles thinking" and scary books does not count as evidence for anything at all.
At what point does the cognitive dissonance hit and people wake up and say, maybe I was wrong?
Probably never.
Beliefs are a tricky thing and wrong beliefs have caused more problems in world history than AI ever will.

Re @demishassabis CEO of Google DeepMind, one of the AI geniuses of our time, thinks Artificial General Intelligence will be achieved by 2030.
That's just 4 years from now.
This past Friday @JerryQian_ attended an invite only talk between Demis and @ycombinator and G-stack CEO @garrytan on the future of AI.
Topics were focused around the latest on Gemini and Gemma, YC alumni building Google's AI tools and conversations with some of the people building some of the most important AI infrastructure today.
Some key points here from the talk.
1. AI agents are the FUTURE. Yes it's a buzzword but if you don't want to be left behind you should be doing everything you can to learn agents, buy a course, go to conferences, take expert agent builders out for coffee, watch Youtube videos and most importantly try building agents yourself.
2. At some point soon Agents will run so autonomously they'll be calling thousands of tools and talking to each other to solve tasks so efficiently that there will be no need for human-in-the-loop except in rare cases.
3. Every task today breaks down to a coding task. Understanding and responding to emails is coding, building slide decks is coding, updates spreadsheets is coding, even selling a product on a video call is CODING. Code is how agents are built, how they run their tasks and communicate.
4. AI might not be THAT cheap just yet but it is only getting cheaper and cheaper as energy production ramps up and models/AI infrastructure tech become more efficient. Not spending money on AI today because it is not "that good" for how much it costs is just handicapping yourself for the near future when it is "THAT good" and VERY cheap.
5. Agents are not good enough to "kill another company" upon a new feature release just yet, much to the dismay of all the X and LinkedIn engagement farmers posting every time Anthropic drops a new Claude feature lol. Agents still need human input to create something substantial, but Demis believes in the next 6 to 12 months even a kid will be able to vibe-code a $10M product by themselves.
6. If he could go back to 25 years old again he would focus on the hard problems such as deep tech. Anyone can build AI wrappers these days but what is the moat there especially as models commoditize. He is more bullish on deep tech as a much deeper moat and the defensible play.
With his prediction of achieving AGI by 2030 he recommends everyone to plan how your company might be affected by AGI and to plan defensibility for your company and how you may leverage AGI instead of letting it disrupt your business.
Thanks Jerry for sharing your notes and learnings with the team as I was not able to attend.

Jack Dorsey, co-founder of Twitter (now X) and Block, on why treating AI as a "copilot" is a losing strategy:
@jack argues that most companies are approaching AI in a way that will make it nearly impossible for them to survive.
"I think most of the industry is thinking about AI as like a co-pilot, as something that is augmented onto, rather than like how do you just rebuild our whole company with this as the core."
His concern is that bolting AI onto existing structures produces companies that look indistinguishable from each other, and from the AI labs themselves.
"If it doesn't make sense for your business to do that and you end up being or looking very similar or rhyming too closely with the frontier labs, then I think it's going to be very, very challenging to differentiate and survive."
This thinking has been driving his decisions since early 2024, when these tools "really came to bear."
That's when his team began building Goose, an agent coding harness, as part of a broader effort to rebuild around AI rather than layer it on top.
The core insight?
Speeding up old workflows with AI is a short-term gain every competitor will match. Real differentiation comes from rebuilding the company itself around intelligence.

profitable apathy
if you thought saas-pocalypse was bad wait until computer use comes for consumer financial services and vampire squids the whole thing
there are many, many profit pools that depend on apathy/laziness and a poorly informed customer - the industry that brought you the efficient market depends on an inefficient consumer to eat
first the models will systematically exploit every customer subsidy (transfer bonuses / teaser rates), move deposits to maximize yield, open and close accounts on a whim - this industry has operated with asymmetric bureaucratic warfare through paperwork and sheer friction and the models will cut through this like a hot knife through butter
and the model will neatly route around late fees, interest charges, overdrafts, expiration of teaser rates, and any mispriced debt that can be refinanced in the market - literally just moving people out of expensive debt and into cheap debt (that they are already approved for!) would save many american families thousands per year
meanwhile vps and managers at these companies will hold on to their shrinking revenue lines the same way that executives at carriers protected SMS revenue as it collapsed to zero - they have zero chance of sticking the landing on new technology - and the smart ones will likely go for extending regulatory capture into the agentic economy
so much of the consumer financial services ecosystem is marketing via subsidies on one end and profit maximization via customer apathy on the other, and it will collapse under its own weight as the agents pick it apart
ironically the industry response to plaid was a misguided attempt to protect this very "profitable apathy" by disallowing APIs and in the end it will be agents that kill them clicking around their own UI, not the fintech aggregators they so greatly feared
the end state of this is likely a headless auction where every time you swipe your credit card, some lender bids on taking the risk and capturing the profit from that transaction - it will be a much more efficient system that will work much better for consumers, and many pockets of financial services are going to see contraction as a result

Rippling crossing a billion in ARR and growing 78% year on year is the best argument against the SaaS is dead meme I've seen. When people say they hate the model what they really mean is they hate the lack of growth.
Rippling is growing because payroll is a market where the entire vibe coding discussion is complete rubbish. You have legal and statutory obligations that carry criminal penalties if you get it wrong. You're not interested in vibe coding your payroll. You want to outsource this to someone wildly competent, have them take the responsibility, and you do not want non-deterministic processes anywhere near it.
AI might change how the software gets built, but the core reason people pay for it doesn't change. It just has to be done right.

My top 5 takeaways from @tibo_maker, a solo AI founder who's making $1M+ a month:

1. Charge money on day one.

Tibo’s first startup failed because he cared more about appearing successful (e.g., I managed a team of 10 and raised $200K) than validating demand with paying customers. “If there is no revenue and no stickiness in the revenue, it’s going to be very hard to build a successful business.” Free signups are easy to mistake for traction.

2. Follow the signal when users surprise you.

Tibo acquired Typeframe ($2K MRR) as a product video tool, but noticed users were hacking it to stitch 5-second AI clips into longer videos with consistent characters and scenes. He pivoted the entire product to meet this need and rebranded it to Revid, which is now making $600K+ MRR.

3. Price your AI SaaS at $50-100/month

Low enough that customers don’t need a sales call and high enough to filter out tire-kickers. “I see so many people charging $10 / month and it puts you into the position of a cheap product.” Tibo picks his price point first, then shapes the product around it.

4. Keep monthly churn below 20%.

If more than 20% of customers cancel each month, stop scaling acquisition and fix the product first. There’s a ceiling (max MRR) on your revenue based on churn vs. acquisition. At 40% churn, customers stay about 2 months and you’ll hit a wall no matter how much you spend.

5. Build tool pages to rank on Google

Revid has 100+ pages each targeting a specific Google search like “turn audio into video” and “YouTube to shorts.” Many AI founders follow a similar model.

Here's my new episode with @tibo_maker, a solo founder who bootstrapped 5 AI products to $1M+ / month.

Tibo walked me through his exact playbook:

✅ How to validate ideas and fail fast
✅ Why his top

My top 5 takeaways from @tibo_maker, a solo AI founder who's making $1M+ a month:
1. Charge money on day one.
Tibo’s first startup failed because he cared more about appearing successful (e.g., I managed a team of 10 and raised $200K) than validating demand with paying customers. “If there is no revenue and no stickiness in the revenue, it’s going to be very hard to build a successful business.” Free signups are easy to mistake for traction.
2. Follow the signal when users surprise you.
Tibo acquired Typeframe ($2K MRR) as a product video tool, but noticed users were hacking it to stitch 5-second AI clips into longer videos with consistent characters and scenes. He pivoted the entire product to meet this need and rebranded it to Revid, which is now making $600K+ MRR.
3. Price your AI SaaS at $50-100/month
Low enough that customers don’t need a sales call and high enough to filter out tire-kickers. “I see so many people charging $10 / month and it puts you into the position of a cheap product.” Tibo picks his price point first, then shapes the product around it.
4. Keep monthly churn below 20%.
If more than 20% of customers cancel each month, stop scaling acquisition and fix the product first. There’s a ceiling (max MRR) on your revenue based on churn vs. acquisition. At 40% churn, customers stay about 2 months and you’ll hit a wall no matter how much you spend.

Re AI for Low-Pesticide Agriculture
@garrytan
Farmers are stuck in a bad loop: use more chemicals, get diminishing results, pay more, take on more risk. And they can't just stop, because if pests win, crops die.
AI that can identify individual weeds in real time, robotics that can treat one plant instead of blanketing a field, and new biological solutions mean this problem finally looks solvable.

So glad others are finding it useful!

Bamboozled is the right term when grifty nonprofits prey on SF Unified School District with lofty sounding pablum PowerPoint slides about Ethnic Studies they sell our schools for 6 figure big paydays

This is the salary of a few SF teachers. Didn’t the district just do layoffs?

Blueprint: “I felt a little bamboozled. There was no room for my voice. And if there’s no room for my voice in the review, what does that say about what happens in the classroom?”

Before tomorrow's School Board meeting, tell @SFUnified to fix Ethnic Studies.

I was on a cruise ship last week (Star of the Seas), and they had pods of 10 elevators in a circle, where you picked your destination floor on a pad, and it directed you to the correct elevator, which was often behind you.

It seemed to work efficiently, but multiple times I saw people tap their floor and just look away, conditioned for normal elevator operation, and miss the arrival of the elevator they were supposed to get on.

Addressing my normal pet peeve of interaction feedback latency would have helped — with all the fades and slides, it takes over a second for the first hint of the elevator to show up, and two seconds for it to fully stabilize. That may not seem like much in some circumstances, but it is plenty of time for people to look away. The elevator letter should appear instantaneously, maybe with some festive animation around it to hold attention that was on the button press.

Even better would be to add a localized audio cue from the elevator the instant you pressed the button, which would let you immediately know where it is without having to scan for the lighted letter.

(the Starlink internet on the ship was excellent, allowing me to get some work in at sea)
