Foundry (YC F24) is hiring – Come build a world model for the web
by lakabimanil | 2025-04-25 17:00:19+00:00
### Stop building GPT wrappers. Build a world model instead.

---

*Why Foundry exists:*

Every SaaS app, enterprise tool, and internal workflow without an API will soon be automated by browser agents—not traditional API integrations. Tens of trillions of dollars in global labor depend on browser-based workflows that no AI system can reliably automate today.

But browser agents right now are like GPT-1: impressive demos, but brittle and broken in practice. To scale browser agents from GPT-1 demos to GPT-4 reliability—and unlock this enormous economic leap—they need purpose-built infrastructure:

- *Realistic web simulation*: capable of modeling complex tasks, ambiguous UIs, and non-deterministic interactions. - *Robust RL training loops*: that learn effectively from sparse rewards and authentic user behavior. - *Rigorous evaluation benchmarks*: tied to real-world outcomes and genuine business impact.

No one's built it yet. We're going first.

We’re building exactly this—core infrastructure designed from first principles, specifically for browser agents. No incremental tools, no wrappers around GPT—just the foundational AI stack everyone else will depend on later.

Our founding team is ex-Scale AI & Meta

Seed-funded, SF-based (fully in-person)

---

*What we’re looking for:*

A founding engineer who’s cracked at software engineering—but who now wants to ship core ML systems and RL infrastructure from scratch.

This is not another prompt-engineering job.

*You’ll:*

- Build a browser agent gym—sparse rewards, non-determinism, messy DOM trees. - Solve hard ML problems at the edge of production—every single day.

---

*You probably:*

- Are a killer engineer (Python, TypeScript) early in your career (0–2 YOE). - Ship insanely fast—internships, side projects, OSS, real research—things you’ve built yourself. - Have real ML exposure: trained models, built infra, ran experiments. - Have strong OSS contributions, publications we’d recognize, or both. - Want a grind. Want to get better. Want to build something genuinely novel.

---

*Bonus points:*

- You’ve built RL agents, browser automation (Puppeteer, Playwright), or eval tooling. - You’re tired of wrapping APIs and fine-tuning HuggingFace models—ready to do something deeper.

---

*Why join:*

- Real-world ML infrastructure, real users, real technical complexity. - Early equity, competitive pay, and massive growth trajectory. - SF-based, 5 days/week, fully in-person.

We're building core infra. The ML stack everyone else will use later—that’s what we’re shipping today.

---

If you’ve read this far, you probably get it.

Reach out directly—let’s build.

Not sure which ranger you're talking about - but if you mean the 6ft one, 18 inches of bed length is definitely noticeable.

It's also definitely possible to haul all those things with almost any truck. Hell, you could even buy a rack for a maverick that makes full 8ft by 4ft sheets of drywall/plywood super easy to carry around, but being able to really easily load up stuff and not have to do some complicated strapping/securing of the payload is a big win with a bigger bed. I personally haul motorcycles a lot, and being able to have two motorcycles in the bed with tailgate up is a huge plus for me.

edit: misunderstood your first comment. What year Ranger are you talking about? The difference between an 80's/90's small truck and an early 2000s can be very considerable.

There's a whole different conversation and argument about the general size of vehicles in the US that is essentially circular and leads to bigger and bigger vehicles in the name of "safety".

If the timing weren't so off (I just bought a compact electric car), then this would have been a real possibility for me: 150 miles is about 1 weeks worth of driving for me, it's usually just me (or occasionally +1), and we have my wife's car for driving the whole family long distances. Of course I'm skeptical that it will come in under $27,500 (implied by the "Under $20k after federal incentives), and if it's much more than that it will start to get squeezed by other options.

AFAIK, The newer models for image gen like this OpenAI one, don’t actually use the normal diffusion process (image generates all at once from blurry to finished), but use transformer architecture where the full final image is generated from top to bottom, as a stream of ‘tokens’.

That’s why when you generate an image in chatgpt nowadays, it will start displaying in full resolution from the top pixel row and start loading towards the bottom.

> Catering to families means expensive bells and whistles, like entertainment systems, etc.

It absolutely does NOT mean those things.

Cars didn't have entertainment systems for nearly a century and families did just fine.

My entertainment system was the window. Observe the world, not just whatever AI-generated garbage some algorithm pushes to a small screen 8-10 inches away from your eyes.

Show HN: Magnitude – open-source, AI-native test framework for web apps
by anerli | 2025-04-25 17:00:35+00:00
Hey HN, Anders and Tom here - we’ve been building an end-to-end testing framework powered by visual LLM agents to replace traditional web testing.

We know there's a lot of noise about different browser agents. If you've tried any of them, you know they're slow, expensive, and inconsistent. That's why we built an agent specifically for running test cases and optimized it just for that:

- Pure vision instead of error prone "set-of-marks" system (the colorful boxes you see in browser-use for example)

- Use tiny VLM (Moondream) instead of OpenAI/Anthropic computer use for dramatically faster and cheaper execution

- Use two agents: one for planning and adapting test cases and one for executing them quickly and consistently.

The idea is the planner builds up a general plan which the executor runs. We can save this plan and re-run it with only the executor for quick, cheap, and consistent runs. When something goes wrong, it can kick back out to the planner agent and re-adjust the test.

It’s completely open source. Would love to have more people try it out and tell us how we can make it great.

I'm amazed the immigrant actually even attended the court hearing in a climate like this. The person went to the court hearing in good faith. Anyway, probably less people will be going to court hearings now.

Wisconsin is also a major money pit for Elon, for whatever reason it's a battleground for everything that's going on this country:

Musk and his affiliated groups sunk $21 million into flipping the Wisconsin Supreme Court:

Japanese cars, particularly cars that have been orphaned, keep their value at high mileage.

If I had to get a high mileage car in a hurry in upstate NY with some expectation that my acquisition + repair costs would be reason I'd go looking for a 2005 Buick. Maybe half of that is getting older, the other half is that my son drives a '96 Buick which has needed some creative maintenance but has been rock solid reliable after a flurry of work where we replaced aging parts.

The answer is straightforward. They are a coalition of Brazilian labs (click on the link in the first sentence to get more information) so it seems normal that they would be focusing on the research conducted in their country. Also it is not the first research of its kind as the nature article provides context

> The teams were able to replicate the results of less than half of the tested experiments1. That rate is in keeping with that found by other large-scale attempts to reproduce scientific findings. But the latest work is unique in focusing on papers that use specific methods and in examining the research output of a specific country, according to the research teams.

When I started developing software, machines did exactly what you told them to do, now they talk back as if they weren't inanimate machines.

AI Safety is classist. Do you think that Sam Altman's private models ever refuse his queries on moral grounds? Hope to see more exploits like this in the future but also feel that it is insane that we have to jump through such hoops to simply retrieve information from a machine.

This leaves out a couple important things, at least from the complaint -

1 - ICE never entered the courtroom or interrupted. They stayed outside the room, which is public, but the judge didn't like this and sent them away.

2 - The judge, having learned the person in her courtroom was the target, instructed him to leave through a private, jury door.

These are from the complaint, so cannot be taken as fact, either.
by lolinder | 2025-04-25 17:02:32+00:00
If it can be proven that she deliberately escorted the person through the non-public exit to the courtroom with the intent of helping them evade arrest by officers with a warrant who were waiting outside at the other entrance, how would that not be an arrestable offence?

We're extremely light on facts right now, so I'm not taking the above quoted story at face value, but if one were to take it at face value it seems pretty clear cut.

I'm really struggling with this at the moment. My job is to put out important information for immigrants. I am often putting new information on the internet, or at least a uniquely clear and complete summary of complex information. That information is not easily observable. Getting it requires a network of human beings who are experiencing German bureaucracy in person.

If I had a guaranteed income, I'd dedicate my life to documenting the real world in useful ways.

AI will not replace this work, but it's effectively removing all the incentives to keep doing it. I'm deprived of my audience and its encouraging words. I'm deprived of the revenue that keeps me going. I'm deprived of the community around the website and all the friendships that it spawned.

I wanted to write about the abandoned kasbah of Foum Zguid yesterday, because no one else did. However it feels pointless if it will just end up as an AI summary that's completely disconnect from me.

The way I see it, it's as if the free eggs I gave to my neighbours ended up in a Holiday Inn's breakfast buffet.
by imoreno | 2025-04-25 17:02:41+00:00
It seems performative. They remove a bunch of stuff nobody ever complained about, like paint or radio. Meanwhile it still has an app and it's still electric with pitiful range. The goal isn't to actually fix the car market, but provide a sort of self-flagellation experience so people can feel good about suffering with no radio, no ac, no auto windows... And I doubt they will reach that goal, sounds more like some kind of investor scam. With all these controversial design decisions they can brag to investors it's "making waves on popular platforms like hn".

really appreciate the constructive criticism — you're totally right, i should’ve highlighted the sources more clearly.

there were three main pieces of actual evidence i leaned on:

1. the nytimes story on account silencing, https://www.nytimes.com/interactive/2025/04/23/business/elon...

2. the visible boost of low-value tweets (though i should have connected to the x api hose and quantify the data),

3. this paper — https://github.com/timothyjgraham/AlgorithmicBiasX/blob/3f4c...

which actually didn’t make it to the the post because the essay was basically finished by the time i remembered i had it. I should have included it. it shows an algo change that boosts elon’s reach specifically.

every other source was speculative:

superbowl fiasko - https://www.theguardian.com/technology/2023/feb/15/elon-musk... - little evidence

elon forced 100 engineers to boost his tweets ? - hearsay

there are also supposed whistle blowers - https://substack.com/@theconcernedbird/p-154577954 - but again. no evidence.

And the algorithm is still closed source.

i’m sorry the writing beyond the graph didn’t land for you.

mr gruez - I'll do better next time.

This would be pretty sad if she did help him evade ICE. He was in court for battery charges and in the country illegally. ICE arresting him does not interfere with any due process. Which he 100% needs to get (but arresting him is still part of that).

What is left here thats worth protecting? Not someone we want in the country and the agents had a warrant for his arrest (court comes after that). I feel like this is a serious own-goal by the people opposing this. Read the complaint corroborated by witnesses - she clearly did help him evade arrest: https://storage.courtlistener.com/recap/gov.uscourts.wied.11...

It’s not that the agency is wrong; it’s that the agency would do it. This is the agency that since J Edgar Hoover has very carefully rebuilt its reputation and is very guarded in it. This act is entirely reminiscent of the political corruption of the FBI of old. That regression, that fast, is frightening.

ICE being shady is by many people accepted, the DEA, ATF even. But the FBI has built itself a pretty strong reputation of integrity and professionalism, and resistance to political pressure and corruption. In some ways I at least viewed it as a firewall in law enforcement against this sort of stuff.

Now who watches the watchers?

Relying on a mobile app is relying mobile operating system compatibility over the years and is just asking for combinatorial methods of obsolescence via OS/app/library breaking changes, plus if your old phone breaks, etc. Open sourced mobile app with open sourced back end might be somewhat acceptable but otherwise it's just asking to be bricked as soon as one of the companies involved goes under as we have seen time and again just in past couple of years.

I found an example!

https://retail.direct.zurich.ch/resources/definition/product...

Questionnaire Zurich Cyber Insurance

Question 4.2: "Do you have a technically enforced password policy that ensures use of strong passwords and that passwords are changed at least quarterly?"

Since this is an insurance questionnaire, presumably your answers to that question affect the rates you get charged?

No, absolutely not. Trump would federalize the national guard as did Eisenhower, Kennedy, and Johnson and charge the governors with treason. You advocate for de facto succession of the states - we settled that matter with blood last time. The next time will be far worse.

The rule of law does not prohibit bad arrests nor can it. The rule of law provides the opportunity for remedy after the fact.
Show HN: Springus – Outfit recommendations from your real wardrobe using AI
by geooff_ | 2025-04-25 17:03:53+00:00
Hey HN,

Since starting to work from home, I noticed my motivation to get dressed in the morning tanked. I’d default to the same sweatpants, which started affecting my mood and productivity. I wanted something to nudge me to dress better—without making it a chore.

That’s why I built Springus, a wardrobe companion for iOS. Instead of manually cataloguing every item, Springus uses a multi-class segmentation model to build your digital closet from fit pix. The recommendation system then suggests outfits from clothing you actually own, aiming to reduce decision fatigue and help you find combinations you might not have considered.

The hardest part was making the segmentation work reliably with real-world photos — messy backgrounds, bad lighting, and all. I ended up training a custom model on hundreds of my own fit pics and some of friends, iterating until it was good enough to share.

I’ve been using Springus every day for the last 2 months. It’s free, and there’s no catch — I plan to monetize later by recommending clothes that fit your style, but right now, it’s just a passion project I wanted to share.

If you’re interested, I’d love feedback — especially on the segmentation accuracy and the outfit recommendations. What would make this genuinely useful for you?

Just ask Microsoft about Tay. On the one hand, I understand why you want some censoring in your model, on the other, I think it also cripples your models in unexpected ways, I wonder if anyone's done such research, compare two models by the same source training data, one with censoring of offensive things, the other without. Which one provides more accurate answers?

"a couple were arrested over complaints they made about their daughter's primary school, which included comments on WhatsApp.

Maxie Allen and his partner Rosalind Levine, from Borehamwood, told The Times they were held for 11 hours on suspicion of harassment, malicious communications, and causing a nuisance on school property."

Got any evidence to support why you disregard what people say? If you need a place where everyone agrees with you, there are plenty of echo chambers for you.

> A tiny minority of Americans are so often at a home supply store that choosing a pickup over a trailer would make any sense.

Your scenario here makes even less sense because most cars do not come with a trailer hitch (trucks on other hand...), you're buying another thing (which lowers that this is supposed to be an "affordable" EV), you have to renew registration for the trailer, and have a place on top of your vehicle to store it.

A truck bed is nice to have sometimes. You can quickly throw things in it (like plywood, a new large flat screen, bicycles, fishing gear, a dead deer, etc). You don't have to hookup a trailer or fiddle with wiggling things between doors and so forth.

I think the claim underneath the comment above is that immigration laws have been not been enforced or unevenly been enforced. On principle, advocating for a consistent application of the law seems sensible. This goes along with advocating for the rule of law.

Let's talk about justice, too. Many people believe true justice transcends any particular instantiation of the law at any particular point in time. If so, advocating for the consistent application of all laws can only be truly just if the laws are just.

Look at present circumstances. Reporting has shown that Trump is doing extraordinary rendition: removing people without due process. And not bringing them home after admitting the mistake. Once this reality is factored in, where is the justice in consistently applying a law in order to extrajudicially render a person?

Clearly, the Trump administration has a double standard regarding the rule of law and the role of the judiciary.

Note: this comment surely needs another draft, but I'm running out of time. I welcome all criticism.

P.S. At the risk of surfacing even more complexity, even if a system were to consistently apply one set of criteria, such as ICE's authority to arrest, it is likely that other criteria apply; namely, allocating personnel in a way that best carries out their overall mission. It is my (educated) guess that practical concerns (such as resource limitations) is one of the reasons courts give administrative agencies considerable flexibility in what laws they enforce.
by pc86 | 2025-04-25 17:04:45+00:00
That's certainly one interpretation of it, and a pretty reasonable one. However, I typically interpret it as "if the police think you've committed a crime, you are going to jail and almost nothing is going to stop that." In that incredibly famous "Don't Talk to the Police" talk[0], the attorney asks the former-cop-turned-law-student if he's every been convinced not to arrest someone based on what the suspect said. Not a single time in his entire law enforcement career.

This is also sort of the crux of the talk - if nothing you can say will convince the police not to arrest you, and things you do say can make things worse, your best bet is to just shut up and talk to an attorney if it gets to that point.

I doubt CAN bus will be around that much longer, I know several EV manufacturers are actively phasing it out. Yes, it was revolutionary in it's time but it's a 40 year old standard that doesn't have enough bandwidth for the requirements of modern cars, and it was designed before security was even a thought. It's also unnecessarily complex wiring that adds weight to the car. Even the updated FD standard is only 8 mbps, so it's barely enough for video from a backup camera.

>The problem is, with modern cars it's not "just" a multimedia interface like a car radio - these things are also the interface for critical elements like windshield wipers. I don't care if your homemade Netflix screen craps out while you're driving, but I do not want to be the one your car crashes into because your homemade HMI refused to activate the wipers.

Lets invent circumstances where it would be a problem to run your own car, but lets not invent circumstances where we can allow home brew MMI interfaces. Such as 99% of cars where the MMI interface has nothing to do with wipers. Furthermore, you drive on the road every day with people who have shitty wipers, that barely work, or who don't run their wipers 'fast enough' to effectively clear their windsheild. Is there a enforced speed?

And my CPAP machine, my blood pressure monitor, my scale, my O2 monitor (I stocked up during covid), all have some sort of external web interface that call home to proprietary places, which I trust I am in control of. I'd love to flash my own software onto those, put them all in one place, under my control. Where I can have my own logging without fearing my records are accessible via some fly-by-night 3rd party company that may be selling or leaking data.

I bet you think that Microwaves, stoves etc should never have web interfaces? Well, if you are disabled, say you have low vision and/or blind, microwaves, modern toasters, and other home appliances are extremely difficult or impossible to operate. If you are skeptical, I would love for you to have been next to me when I was demoing the "Alexa powered Microwave" to people who are blind.

There are a lot of a11y university programs hacking these and providing a central UX for home appliances for people with cognitive and vision disabilities.

But please, lets just wait until we're allowed to use them.

Are LLM "jailbreaks" still even news, at this point? There have always been very straightforward ways to convince an LLM to tell you things it's trained not to.

That's why the mainstream bots don't rely purely on training. They usually have API-level filtering, so that even if you do jailbreak the bot its responses will still gets blocked (or flagged and rewritten) due to containing certain keywords. You have experienced this, if you've ever seen the response start to generate and then suddenly disappear and change to something else.
