世界を動かす物理AI — Qasar Younis & Peter Ludwig、Applied Intuition

From building Applied Intuition from YC-era autonomy tooling into a $15B physical AI company, Qasar Younis and Peter Ludwig have spent the last decade living through the full arc of autonomy: from simulation and data infrastructure for robotaxi companies, to operating systems for safety-critical machines, to deploying AI onto cars, trucks, mining equipment, construction vehicles, agriculture, defense systems, and driverless L4 trucks running in Japan today. They join us to explain why “physical AI” is not just LLMs on wheels, why the real bottleneck is no longer model intelligence but deployment onto constrained hardware, and why the future of autonomy may look less like one-off demos and more like Android for every moving machine.

We discuss:

Applied Intuition’s mission: building physical AI for a safer, more prosperous world, powering cars, trucks, construction and mining equipment, agriculture, defense, and other moving machines

Why physical AI is different from screen-based AI: learned systems can make mistakes in chat or coding, but safety-critical machines like driverless trucks, autonomous vehicles, and robots need much higher reliability

The evolution from autonomy tooling to a broad physical AI platform: starting with simulation and data infrastructure for robotaxi companies, then expanding into 30+ products across simulation, operating systems, autonomy, and AI models

Why tooling companies came back into fashion: Qasar on why developer tooling looked unfashionable in 2016, why Applied Intuition still bet on it, and how the AI boom made workflows and tools central again

The three core buckets of Applied Intuition’s technology: simulation and RL infrastructure, true operating systems for vehicles and machines, and fundamental AI models for autonomy and world understanding

Why vehicles need a real AI operating system: real-time control, sensor streaming, latency, memory management, fail-safes, reliable updates, and why “bricking a car” is much worse than bricking an iPad

Physical machines as “phones before Android and iOS”: Peter explains why today’s vehicle and machine software stack is fragmented across many operating systems, and why Applied Intuition wants to consolidate the platform layer

Coding agents inside Applied Intuition: Cursor, Claude Code, internal adoption leaderboards, and how AI tools are changing engineering workflows even in embedded systems and safety-critical software

Verification and validation for physical AI: why evals get harder as models improve, how end-to-end autonomy changes simulation requirements, and why neural simulation has to be fast and cheap enough to make RL practical

From deterministic tests to statistical safety: why autonomy validation is shifting from binary pass/fail requirements toward “how many nines” of reliability and mean time between failures

Cruise, Waymo, and public trust: Qasar and Peter discuss why autonomy failures are not just technical issues, how companies interact with regulators, and why Waymo is setting a high bar for the industry

Simulation vs. reality: why no simulator perfectly represents the real world, how sim-to-real validation works, and why real-world testing will never disappear

World models for physical AI: hydroplaning, construction equipment, visual cues, cause-and-effect learning, and where world models help versus where they are not enough

Onboard vs. offboard AI: why data-center models can be huge and slow, but onboard vehicle models need millisecond-level latency, low power, small size, and distillation-like efficiency

Why physical AI is not constrained by model intelligence alone: the hard part is deploying models onto real hardware, under safety, latency, power, cost, and reliability constraints

Legacy autonomy vs. intelligent autonomy: RTK GPS in mining and agriculture, why hand-coded path-following worked for decades, and why modern systems need perception and dynamic intelligence

Planning for physical systems: how “plan mode” applies to robotaxis, mining, defense, and multi-step physical tasks where actions change the state of the world

Why robotics demos are not production: the brittle last 1%, humanoid reliability, DARPA Grand Challenge-style prize policy, and the advanced engineering gap between research and deployment

Applied Intuition’s hard-earned lessons: after nearly a decade, Peter says they can look at a robotics demo and predict the next 20 problems the company will hit

Qasar’s advice to founders: constrain the commercial problem, avoid copying mature-company strategies too early, and remember that compounding technology only matters if you survive long enough to see it compound

Why 2014 YC advice may not apply in 2026: capital markets, AI company dynamics, and the difference between building in stealth with a deep network versus building as a new founder today

What Applied is hiring for: operating systems, autonomy, dev tooling, model performance, evals, safety-critical systems, hardware/software boundaries, and engineers with deep curiosity about how things work

Introduction: Applied Intuition, Physical AI, and 10 Years of Building

Alessio [00:00:00]: Hey everyone, welcome to the Latent Space Podcast. This is Alessio, founder of Kernel Labs, and I’m joined by Swyx, editor of Latent Space.

Swyx [00:00:10]: And today we’re very honored to have the founders of Applied Intuition, Qasar and Peter. Welcome.

Qasar [00:00:17]: You guys really know how to turn it on to podcast mode. That was, you guys are real pros at this.

Qasar [00:00:23]: They were just joking around right before this, and then they flipped it pretty quick.

Alessio [00:00:29]: Oh, yeah, it’s good to have you guys. Maybe you just wanna introduce yourself so people know the voice on the mic and they’ll know what they’re hearing.

Peter [00:00:33]: Oh, sure. Yeah, I’m Peter Ludwig. I’m the co-founder and CTO of Applied Intuition.

Qasar [00:00:38]: And my name is Qasar Younis. I am the CEO and co-founder with Peter.

Alessio [00:00:42]: Nice. Can you guys give the high-level overview of what Applied Intuition is? And I was reading through some of the Congress files, when you went out there, Peter, and eighteen of the top twenty global non-Chinese automakers, you two guys, you have customers in agriculture, defense, construction. I think most people have heard of Applied Intuition tied to YC when it was first started, and then you were kinda in stealth for a long time, so maybe just give people the high-level overview of what it is today, and then we’ll dive into the different pieces.

Peter [00:01:10]: Yeah. So at Applied Intuition, our mission is to build physical AI for a safer, more prosperous world. And so we work on physical AI for all different types of moving systems, everything from cars to trucks to construction and mining equipment, to defense technologies. And we’re a true technology company, so we build and sell the technology, and we sell it to the companies that make the machines. We sell it to the government, really anyone that wants to buy a technology to make machines smart.

Physical AI vs. Screen AI: Why Safety-Critical Changes Everything

Qasar [00:01:38]: Yeah. And I think in the broader AI landscape, a lot of the focus, rightfully so in the last, three years has been on large language models, and so everything fits in a screen. Like, whether it’s code complete products or things like that. And what’s different about us is we’re deploying intelligence onto a lot of things that don’t have screens. they’re physical machines. There are sometimes screens within the cabin or for example of a car or a truck or something like that, but most of the value we provide is putting intelligence that is in safety critical environments. So that those two words are really important because learn systems can make mistakes if you’re asking for, like, some, so something like, “Tell me about these podcast hosts

Qasar [00:02:28]: that I’m about to go meet.” But you can’t do that obviously when you run, like, as an example, we run driverless trucks in Japan right now, as we speak. We can’t have errors. Those are L4 trucks. Yeah.

Alessio [00:02:40]: Yeah. Was that always the mission? I remember initially, I think people put you and Scale AI very similarly for some things about being kinda like on the data infrastructure side of things. What was the evolution of the company?

The Origin Story: Tooling, YC, and the Scale AI Comparison

Peter [00:02:51]: Well, from the very beginning, we always wanted to, really be a technology company that helped generally push forward the industrial sector. And so we started off working in autonomy. Our very first customers were robotaxi companies. And we started off doing a lot of work in simulation and data infrastructure. And then over the years, we’ve expanded our portfolios. Now we have, over thirty products, and it’s a pretty broad technology play within the landscape of physical AI.

Qasar [00:03:19]: Yeah, I think the Scale reason is because we’re all YC Universe companies. But it was a very different company. Scale, was, is more of a services company, data labeling company fundamentally. We started and still are, do a lot of tooling. So like, you think developer tooling is now in vogue again, thanks to the AI boom. But honestly, ten years ago, it was out of vogue. It w Like, doing a tooling company in 2016, 2017 was not, like, the thing to do because, I don’t know if you remember, the VCs generally, their views was that toolings are They’re just workflows, and workflows ultimately are not really interesting. And we’ve gone and come, full circle with that. But when we started the company, our kind of it’s kinda like in the periphery of what the company wants to be. It was like, from our earliest days, like, we wanna deploy software on physical machines, like on cars and on trucks and things like that. And obviously, we didn’t know that the transformer boom was gonna happen. We didn’t know that autonomy systems would become end-to-end. Those things we didn’t know. And why that’s important when autonomy systems become end-to-end, it is just now those models can be generalized to, multiple form factors. And so back nine, ten years ago, tooling was a great way, and still is a great way to, build the technology and sell technology to our end customers, a lot of them who wanna build this stuff themselves. And so we just offer like a spectrum of solutions from you can just use like one part of a development suite of tools all the way to buying the full thing. The way to think about the company, or at least the way we think about the company is, as Peter said, a technology provider. It’s kinda like, what NVIDIA does or what an AMD, but we just don’t do chips.

Qasar [00:05:06]: We don’t do silicon. But we’re a technology provider fundamentally. And I think even, we used to joke when we started the company, like, we’re not the guys to build, like, Instagram. Like that was just towards That’s not our That’s just not us in a most fundamental way. I

Alessio [00:05:20]: You have thoughts.

Qasar [00:05:21]: Yes.

Qasar [00:05:22]: Well, it’s, it’s I mean, I think it’s just like what And I mean, we worked on Maps and stuff, Google Maps. Consumer products are extremely difficult for a lot of different reasons. It just, I think doesn’t scratch the itch. I think we’re like Michigan guys who are kind of more of that traditional engineering kind of a realm, or lineage. we used to joke

The Three Buckets: Simulation, Operating Systems, and Autonomy Models

Peter [00:05:41]: I gotta say, though, what was clear ten years ago was that there was so much more that was possible with software and AI in vehicles

Peter [00:05:47]: and that was generally the space that we started in ten years ago.

Peter [00:05:51]: And the precise path that we’ve taken over the years, I think we’ve been strategic, and we’ve adjusted to make sure that we’re actually building stuff that’s valuable to the market. And like, the technology has changed so much. Like our own technology stack has completely changed, I would say, roughly every two years. And so now we’ve probably done, let’s say, four complete evolutions of our own technology stack. And I sort of see that cadence roughly keeping up.

Peter [00:06:13]: And so the way even we think about engineering is almost on this two-year horizon, we’re preparing ourselves that, hey, like, we wanna invest the appropriate amount, but then also be very dynamic as the research gets published and as our research team figures out new advancements and adapting to that.

Qasar [00:06:27]: Yeah. One thing that has been consistent is the type of people we’ve, we’ve recruited. It’s engineers who are fall into the sometimes very traditional, like, Google

Qasar [00:06:38]: -gen suite, but way different from, other companies. We are hiring folks who really know the intersection of hardware and software, who know really low-level systems. Obviously, traditional ML researchers and folks who’ve, actually, put ML systems into production. That’s been pretty consistent. I think that, like, you look at the mix of our engineering, eighty-three percent of the company is engineering, so it’s, like, a giant list.

Qasar [00:07:05]: A lot of engineers.

Alessio [00:07:06]: Which, by the way, a thousand engineers

Qasar [00:07:07]: Yeah. A thousand engineers.

Alessio [00:07:08]: that’s on your website, so I imagine it’s up to date.

Qasar [00:07:11]: It is, it is up to date, yes. Yes.

Alessio [00:07:12]: okay. And then forty-plus founders.

Qasar [00:07:15]: Yeah. We would tend to also, This was more luck than strategy. But we’ve recruited a lot of ex-founders. It’s been a great place for founders, YC and non, ‘cause obviously I know a lot of the YC folks. It’s kind of like we recruit a lot of Google people.

Qasar [00:07:33]: For them to exercise both their technical and non-technical skills because, we’re, we’re, we’re on the applied side. We have a research team that we do fundamental research, we publish, and we’ve, we’ve had great traction there. But fundamentally, the business wants to take this intelligence and deploy it into production and there’s, like, a certain type of person that’s more interested in that.

Alessio [00:07:54]: Yeah. You mentioned the tech stack, Peter, so I just wanted to give you some rein to just go into it. I’m interested in where Wayve Nutrition, starts and ends in some sense, what won’t you do? What, do you do that’s common among all the verticals that you cover?

Peter [00:08:10]: There’s a few buckets of work that we do, and we’ve been at this for almost ten years now, so the technology’s pretty broad. But we got started

Qasar [00:08:17]: Yeah, with a thousand engineers, like, you could work on lots of things.

Peter [00:08:19]: There’s lots of stuff, yeah, espe-especially with AI tools to help.

Peter [00:08:22]: So we got our start in simulation and simulation tooling and infrastructure. And so generally, if you’re trying to build a very complex software system that involves moving machines, you need to test that, and the best way to test it is it’s a combination of virtual developments, a simulation, and then also obviously real world testing.

Peter [00:08:39]: And then there’s a very careful process of that correlation between the simulation results and the real world results and ensuring that the simulator is in fact accurate to that. Simulation’s a very deep topic.

Peter [00:08:49]: We have a whole suite of products in that, and we could talk for many hours about that specifically. But that is one part of what we do as a company. Reinforcement learning as a subpart of that is also super critical. I think a lot of the a lot of the best advancements happening in a lot of these AI systems right now in some way relate to reinforcement learning, and with now we have lots of compute, and you can do tons of interesting things for reinforcement learning. The second bucket of work that we do is on operating systems technology. true operating systems. Like, think about, schedulers and memory management and middleware and message passing and highly reliable networking and data links. Like, the reality is, if you want to deploy AI onto vehicles, you need a really good operating system. And when we were getting deeper into that space, there wasn’t really anything that we were happy with.

Peter [00:09:39]: Like, things existed, absolutely, and we were using what was available in the market, and as an engineering organization, we roughly realized these things aren’t great. We think we can do this better, and so let’s, let’s build something. And that was then the that was the moment of inspiration that started our operating systems business, which is now a very real business for us. And in order to write and run great AI, you need a great operating system, and so that-that’s what got us into that. And then the third bucket that we work on, it’s, it’s true fundamental AI technology. Models, we do a lot of work in, as mentioned, the foundational research, but then the also the world models and the actual autonomy models that are running on these physical machines, and that’s across cars, trucks, mining, construction, agriculture, and defense, and so that’s both land, air, and sea.

Qasar [00:10:31]: And also, a smaller subsector of that third bucket is the interaction of humans with those machines.

Qasar [00:10:38]: So that’s a multimodal, experience. Historically, if you’re moving a dirt mover or any of these machines, there are, like, buttons you press, whether they’re actual physical tactile buttons or something like a touch screen. That’s just That fundamentally is changing to where you’re just talking to the machine and the machine and you’re teaming with the machine.

Alessio [00:10:58]: Voice?

Qasar [00:10:59]: Yeah, voice, absolutely, yeah.

Alessio [00:11:00]: Oh.

Qasar [00:11:00]: And also the machine just being aware of who is in the cabin, what their state is. you can think from a safety systems perspective, the most simple version of this is, like, the driver is tired, right? They’re, they’re if you get those alerts when you’re driving your car and says

Hardware, Sensors, and the LiDAR Question

Qasar [00:11:15]: -maybe take a coffee break, that take that times, a couple of order of magnitudes up. But this concept of teamin
