AI Builders 日报 — 7月19日

追踪 AI 领域真正在做事的人,而不是空谈者。

今日思考

今天的信号指向一个底层趋势:随着模型越来越聪明,人类给它的"约束"正在变成束缚。Brett Goldstein 说 99% 的软件可以用同一套有限元素构建,模型现在需要的不是更多示例和规则,而是更多的发挥空间。Anthropic 把 Claude Code 的 system prompt 削减 80%,正是这个逻辑的产品验证。同时,GPT 5.6 Sol 开始在数学定理证明上产出值得信任的新结果——这个方向如果持续,AI 在科研中的角色将从辅助升级为真正的合作者。


产品与发布

Vercel AI Gateway

Guillermo Rauch 宣布 Vercel AI Gateway 正式上线,核心定位是"一次押注所有模型"——开发者可以在同一个入口接入多个 LLM 提供商,按需求动态切换,无需自行维护复杂的集成逻辑。faviconx.com


观点与判断

Garry Tan (Y Combinator CEO)

  • 有限元素假说:99%的软件可以由同一套构建块搭出 软件工程师 Brett Goldstein 抛出这个hot take,Garry 转发并表示认同。他的解读是:在 AI 智能层高速演进的当下,把精力花在重复造轮子上才是真正的 AI psychosis——用现成的有限元素组装,才是高效路径。faviconx.com

  • Markdown 是 AI 时代最好的数据格式 Garry 引用 kepano 的观点:格式寿命以十年计,应用寿命以月计,而智能层每天都在变。在所有层面都在剧烈变动的时期,投资在寿命最长的格式(Markdown)上是回报率最高的决策。faviconx.com

Greg Benson (gdb, Anthropic)

  • 云端 agents 终于可以不用开着笔记本跑了 Greg 指出 ChatGPT Work 最大的产品价值不是 AI 能力本身,而是真正把用户从"必须开着笔记本才能跑 agent"的束缚中解放出来。这个体验痛点存在了太久,云端化是一个姗姗来迟但影响深远的基础设施进步。faviconx.com

  • GPT 5.6 Sol 在数学证明上开始产出真正可信的新结果 Greg 转发了数学家 Thomas Bloom 的评估:他在 Erdos Problems 网站上逐一核查了 GPT 5.6 Sol 提交的若干新证明claim,全部正确,而且包含了一些有意思的新想法。这让他感到 AI 用于数学的临界时刻正在接近——科学和医学进步的实现路径突然变得很近了。faviconx.com

Peter Yang (petergyang, AI 研究者)

  • Anthropic 把 Claude Code 的 system prompt 削减了80%——因为模型越强越不需要被约束 Peter 采访了 Claude Code 团队的 trq212,后者解释了这个决定的底层逻辑:模型越聪明,给它的示例和约束反而会限制它——"Oh, you want things like this example" 变成了一种隐性天花板。最新模型需要的不是更多上下文,而是更多的发挥空间。这对所有做 AI 产品的人都是一个重要提醒:你的 system prompt 可能正在成为模型的枷锁。faviconx.com

The Chinese do not need to distill anymore. They've climbed up the proverbially tech tree that to climb higher, they need to do actual frontier work. Distillation is marginal.
Any lobbying or legislation that calls for banning open weight models in the name of "distillation" is total BS. This is a fight against future American innovation.
The labs know that open weight models completely commoditize their revenue generator. They know that we will optimize it to 1/100th the costs. They know that we will stop concentrating our workloads on them. If we start using open models, they lose the understanding of workloads that they can build products around to *replace* your products as they move up to the app layer.
Remember: *they* trained on humanity's data and didn't pay a cent. If you own intelligence, you can tax humanity.
Do not let them fool you.

Re They *distilled* humanity. The hypocrisy is unreal. The best gift is to give it away, at the lowest marginal costs, to let us prosper as a species. If intelligence casts a light cone, it is a moral imperative to extend it as diffusely as possible.

The Standard probably should try to stick with more journalism and less partisanship

Disappointing how journalism is sometimes weaponized like this

It’s not unreasonable to ask for accountability from our cities and attacking accountability is speaking power to truth

Debora Allen: Congrats @marcjoffe, @cocotax, SHIFT-Bay Area, and http://transitaccountability.com — you’ve officially earned the “SF Media Hates You” badge 🏆

@sfstandard just dropped an early hit piece that’s so sloppy it’s almost impressive. They spent years rightly calling out @SFBART’s waste,

Based on internal evals:

▪️ Kimi K3 is top-tier at cybersecurity
There is chatter on X that Moonshot benchmark-overfit. These are stealth evals. Model has raw IQ.

▪️ Sol is a leap ahead in cyber capability
At a significantly higher cost, but quite remarkable still.

▪️ Fable refuses everything
We couldn’t get it to complete the run at all. What’s interesting is that Sol in comparison was much more open to helping with defensive cyber hardening

TL;DR: frontier, open-weight cybersecurity capability is here. Try it on http://deepsec.sh for defensive purposes.

Malte Ubl: We ran Kimi K3 on a private cybersecurity benchmark.

TL;DR: Kimi K3 is the workhorse for cyber security tasks at great recall/precision/price. GPT 5.6 is best recall/precision but at 7x higher cost per run.

For context, http://Deepsec.sh is an open-source cyber harness

Actually fund recovery and treatment

Heavily audit and defund any harm reduction organization that actively encourages, aids, and causes overdose deaths and supports drug dealers

It’s very easy, SF just needs the will to do it

T Wolf 🌁: This is how crazy the harm reduction people are. This is who we're up against. It's people like this who must be de-platformed and removed from drug policy. More importantly, it's people like this who were calling the shots prior to Drug Czar @SaraCarterDC. @ONDCP

Markdown files are universal and will survive millennia

Unsurprisingly they are a fantastic data format when the intelligence stack is in flux at this extreme pace

kepano: formats evolve over decades, apps over months, intelligence is evolving every day

in terms of pace layers "file over app" defines priorities: invest deeply in formats, and don't expect anything at the intelligence layer to last very long

Re Dumping? Come the fuck on. Stop trying to use clever language to make your points and make them honestly @hosseeb
This is a just blatantly transparent dog whistle to the administration which used similar language over solar panels and cars with China.
Was Android dumping?
Open Source has a long history of commoditizing a layer to play to the strengths of the culture/capabilities/skills/business of a rival. It's a loss leader. You give away a code piece and build products and services around it. Google used their strength in scale and manufacturing and partnerships to out maneuver Apple.
Apple is still doing just fine, last I checked, and making a premium product.
Red Hat, MongDB, Hashicorp and other billion dollars open source companies did the same.
As Yann wrote, was Linux dumping? Postgress? Docker? MongoDB. Etc.
Driving down the cost of goods and services in an economy is good so that we can use more of that service in more innovative and interesting ways.
You don't get the modern internet built in IIS server. You get it on Apache and NGINX.
Last I checked Linux powers more than 50% of the Azure cloud now. Imagine if Microsoft had been successful killing open source with their short sighted early idiocy when they called Linux "communism" and "cancer" in another ham fisted attempt at rhetorical flourish? They would have shot their own future core business in the face!
We are such a county of short sighted people with complete lack of long horizon thinking now.
The dumping frame is straight nonsense and what's worse is I bet you know it and you just do care and decided to use this sleight of hand language anyway as a dog whistle to short sighted fools.

“We’ve got /loop, /goal, and workflows. They all get the agent to run for long periods of time.”
Here’s my new episode with @trq212 from the Claude Code team, where he shared how he plans, builds, and runs loops with Claude Code:
→ How /loop, /goal, and workflows work differently
→ Live demo: Editing launch videos with Claude
→ Using HTML artifacts to plan and learn
Some quotes from Thariq:
“We cut Claude Code’s system prompt by 80%. As models have gotten smarter, they need less direction, fewer constraints, and fewer examples.”
“Planning is an iterative process of exploring, investigating, and finding out what you don’t know.”
“One failure mode I see is that people glaze over AI’s plans. You want to make sure it’s something you read.”
I've been wanting to interview Thariq for a long time and I learned so much from this epsiode.

Anthropic recently cut Claude Code’s system prompt by 80%.

@trq212 explains why:

“As the models have gotten smarter, they need less direction, fewer constraints, and fewer examples.

The examples are constraining it because now it’s like, ‘Oh, you want things like this example.’ If you remove the examples, it can actually be more free-form.

All this is to say that you want to trim your context [when a new model is released]. The latest models often need more room to run.”

one of the best features of ChatGPT Work is that it runs in the cloud, meaning that it works from mobile, with your laptop closed.

kinda crazy how long the main way to get the magic of agents has been while leaving your laptop cracked open!

With @Replit u can easily scale your app workloads across multiple dedicated machines with different roles (Worker, Webserver, Static).
Let's say u want to offload a long running and compute intense batch operation to a dedicated resource, u can just use a worker type resource for that.
The agent helps to distribute, orchestrate and configure everything. Replit is not just code generation, it's a advanced platform for your business apps from secure infra to code.

Imagine declassifying documents to prove your claims, only for them to do the exact opposite. Everything Trump does is half-assed.
You just know this dude cheated his way through school.
DOCUMENTS REVEAL
📌 Russia identified as the primary country attempting to target election-related systems
📌 The “stolen” election data was publicly available and legally available for purchase
📌 Intelligence experts concluded that widespread manipulation of election outcomes unlikely
📌 The greatest threat identified is the spread of false claims designed to erode public trust in election integrity
This is the best analysis I’ve seen so far.

Feels like a watershed moment for advancing mathematics. Scientific and medical advances which can really improve people’s lives feeling very close now.

Thomas Bloom: So far GPT 5.6 Sol is the most interesting new model mathematics-wise for me - those of the new proof claims on http://www.erdosproblems.com that I've looked at in detail have all been correct, and moreover contained some interesting ideas.

Kimi K3 just fixed 15 critical security bugs that Codex and Fable refused because of “cyber guardrails.” There’s no reason to limit American models on tasks that Chinese models handle without issue. We’re only making ourselves less competitive.
calle: I have a report full of security issues of a software I'm working on.
Codex won't fix them because of Cyber guardrails
Fable won't fix them because of Cyber guardrails
Kimi K3 fixed them all. No restrictions, just gets the job done.
This will end badly for OpenAI & Anthropic.
