I wonder what will happen with EurekaLabs now. I checked their X account, but the posts are now restricted. However, the background picture... that old AI-generated image feels surprisingly cringe (https://x.com/EurekaLabsAI/header_photo), incredible how much GenAI has improved since that image was created.

If you don't actually have the desire to build, lead, and manage a large organization, this is a terrible idea for technical geniuses. A guy like him will instantly raise $1 billion which means hiring dozens of people, which means tons of interviews, management, performance review, planning, board meetings, etc etc.

It's good that there are avenues today for people to make tens or hundreds of $m in salaried positions at companies so that they don't have to do that stuff to get paid their value if they don't genuinely want to.

Two years ago I’d agree, now he probably wants access to the immense capacity they have where if he were to start a lab from zero now, the ramp up to frontier pushing would require a lot more time. I don’t he needs the money as it is, and wherever he were to go would certainly make it worthwhile financially. Some people may just be cool with a couple hundred million dollars in their lifetime

TrackerFF 13 hours ago|||
Seems to me that you need incredible amounts of money to be competitive in the frontier model arena. I don't know how much money Karpathy has to spend, but I'd imagine that the money needed would almost certainly mean investors with deep pockets.

And then there's the uncertainty, will the AI "wars" be some winner-takes-all situation? Will the smaller labs eventually be acquired by the bigger ones, will they simply wash away if there's a crash?

I don't know. If you can land some exceptional gig at the big firms, maybe the financials are good enough to not start your own lab. Minimizing risk, and all that.

EDIT: Assuming such a startup would focus on frontier models.

He's Andrej Karpathy. He could wait to let the winner surface. Obviously better to get in with the winner earlier. But worse to get on the wrong team versus on the right team late.

He moves around quite a bit. Less than 2 years on average if you take away the longest and shortest jobs. It feels like this is just a celebrity hire to help raise IPO value, and then he'll move again when the tech hits another real-world scaling wall. Expect another short stint (stunt) with Anthropic.

I have to imagine that Anthropic is giving him an equity grant worth $1B or more in their upcoming IPO.

cameldrv 10 hours ago|||
He's an extraordinarily bright guy. He can get a lot more done in two years than most people, and he can get up to speed with a new organization and a new task and be productive much faster than most people.

My impression with no inside knowledge, but understanding what Elon companies are like, is that he was assigned essentially an impossible task at Tesla and tried his very best, but it could not be done, and he semi-burned out. It makes sense for him to be getting back on the horse now.

The Elon approach to management as I see it is to assign what normally would be totally unreasonable goals to a small group of extremely bright people, and they work their asses off and somehow find a way. Sometimes this works, and sometimes it doesn't. If it works and the impossible was in fact, just barely possible, you dominate the market, everyone gets rich, and the people see it as the most exciting, intense, and rewarding part of their career. If it doesn't, they get depressed, divorced, and looking for other work. The Elon magic is threading the needle closely enough that a lot of the seemingly impossible things are in fact possible with enough hard work and brainpower, but although Elon is extremely good at this, the nature of the thing is that you can't predict which side you'll wind up on fully accurately.

That seems like the opposite. Why would someone with high market value stay in one place? 2 years is basically optimal - you vest 50%, maybe collect a promotion, do some good work and learn a lot, and then get to move on for another solid bump/ promotion and a new set of stocks.

I expect the people with low market value to be the ones sticking around labs for long periods of time, they don't have the option to move and they aren't getting poached.

Europe’s labor market is sadly still mostly out of touch with how startups work. It’s stuck in the last century. I’m not sure if this is due to tradition, or due to the fact that startups are much harder to start in Europe in general, so people on both sides of the hiring process have less experience with it.

Two years is more than long enough to join a startup, build 3 things, and see that your equity is never going to be worth anything, and find a new job. This isn’t anomalous or weird.

Yeah, being laid off every 2-3 years is a lot different from job hopping and shows exactly why the games industry is in its own little pocket of screwed in this market. Especially with games taking 3-5+ years to be made. How do you keep institutional knowledge when you kick it all out and basically start from scratch every cycle.

lol this is just not true sorry.

Claude code was one person's idea as a pet project and now it's singlehandedly 5x'd Anthropic's valuation. Sometimes single people matter, that's life.

HarHarVeryFunny 8 hours ago|||
I think both are true. Claude Code was one man's experimental project, but it's an application of AI, not AI itself.

Anthropic is a large company, with thousands of employees, and seems to be 100% (maybe 200%) LLM and scale pilled. All the advances from one model generation to the next are the result of dozens of experiments first at small scale then at larger scale, all competing for the same "development compute" portion of their overall "development + inference" compute resource.

In this environment, even if there are researchers who have ideas not on the "LLM + scale is all you need" path that Dario seems hell bent on, there seems to be not much chance that these ideas can compete for resources and compute with the mainstream experiments that the company believes their future depends on.

Maybe an individual developer like Sutskever, engaged purely in research rather than manning a barely turnable oil tanker, can make a difference, but at a company like Anthropic it seems way less likely. Cherny's baby is 100% aligned with Anthropic's mission of selling LLM tokens. Someone else fighting the mission, trying to pivot Anthropic in a new better direction is not likely to have such luck.

Karpathy is probably one of the biggest names in AI, I do wonder where he fits now. He's sort of bounced around Tesla back to OpenAI back to independent. He sort of left OpenAI before it really hit the inflection point, and he was at Tesla for a long time and they didn't really deliver what they wanted on the AI side. Now he's bounced around a few places. I understand that the leaders in this market play this silly game of trying to buy up the names like trading cards but I wonder what this turns into.
prodigycorp 13 hours ago||
i wouldn't be surprised if he just becomes a glorified marketer for anthro.

im also going to guess that whatever research he does would be free roam research that primarily serves to market the fact that claude was able to help perform the research.

the visible stuff he's been working on has been mostly agent soft skills. off the top of my head is autoresearch and his the wiki knowledge stuff. nothing particularly groundbreaking, but has helped devs expand their understanding of the utility that these models can provide.

not a diss to andrej i know he's reading this now

I think you are underestimating both the value of both projects (autoresearch and personal wiki) just because they are simple. I see both POCs for continuous learning / optmization on the harness layer, which in my opinion is a very interesting direction.

I think Andrej has the experience (and now ressources) to productionize this research into something very interesting.

DiscourseFan 12 hours ago|||
No, these are developed off of the assumed uses of the models (predictive autofiller) rather than their actual, cognitive and potential industrial use (developing large scale frameworks for industrial production, automating systems that normally require human monitoring), and uses that we have not yet discovered, because we have not figured out all the constraints and limitations of these models. If Karpathy was in the game like he used to be, he would be on real product. Right now he’s probably so lost by the very thing he helped create that he is stuck doing these mini projects for his own personal interest, without anyone really critically engaging with his work.

Those projects are a complete joke. Neither of them were even original, people have been playing around with those ideas for well over a year.

They just became "famous" because Karpathy is effectively an AI celebrity, so he could throw shit at a wall and post it on X and it would get 10k Github stars.

But seriously, people have been using the models to tweak hyperparemeters, or using LLMs to help create a second brain using markdown or json files or 100X other combinations of files, for a long time already.

noufalibrahim 12 hours ago|||
I don't think that's the parents implication.

Generally, when a "good" developer has a huge public presence and reputation, that's quite valuable to a company when they're competing in a tough space. Many a time, more so than the (very high) technical skill of the developer in question.

I've seen large funded companies gather good popular developers like pokemon cards and just have them go around give talks and write blog posts. It creates an aura around them which makes things like hiring, fund raising etc. much easier.

So, it's not really a statement about Karpathy himself. It's more about the company hiring him.

Yea, I say this as a marketing agency owner, not a developer or AI researcher, that besides Sam Altman, Dario, Demis and Elon, that Karpathy is one of the most influential I follow.

There’s a lot of value for the business world in learning AI from someone who has been at the top of their game but now is doing a general service by being a great educator and translator between the fields.

His recent Wiki approach may be simple to devs but is certainly an aha moment for the rest of the peanut gallery paying attention!

This kind of thing happens to big names in software all the time.

He already stated his motivation a few months ago in an interview with Dwarkesh - basically saying that he might join one of the big labs, for a while, to keep in touch with frontier research.

Andrej seems like a great guy, but him joining Anthropic feels a bit like a transactional relationship (rich old guy marries hot young chick). Anthropic get a "glorified marketer", and he gets a front row seat at SOTA LLM dev 2026. I don't think they hired him expecting he's going to change the direction/pace of their research.

As an aside, an Indian guy I used to work with once explained to me how traditional Indian arranged marriages, like his own, work, and they are HIGHLY transactional. It's not just a matter of same caste, same social status etc, but an explicit trade off. In my co-worker's case he cheerfully told me how his wife was very dark skinned, therefore considered not that attractive/desirable (to other Indians!), but her family had money and social status so it was considered a fair trade for a nice looking boy like himself!

Since his announcement, Obsidian has taken proactive steps to mitigate the risks, or at least study threat model. Hopefully, they will implement proper RBAC or something before someone else with his visibility announces an even more irresponsible half-baked idea.

FWIW while Karpathy was at Tesla he was basically working on the vision component. The actual driving component (using vision as an input) was originally all C++. They may have started migrating parts of the driving component from C++ to neural networks while Karpathy was there, but most of it happened after he left in 2022, with the big switch being FSD 12 in 2024. User reports from before/after FSD 12 are like night and day.

I'm not talking about vision (cameras) vs lidar etc, just the Tesla FSD architecture that separates the "vision" component (turning camera/sensor inputs into symbolic road/sign/vehicle/pedestrian/etc data), and the driving component which takes the vision data, plus current location and destination, and uses that to actually drive the car - switch lanes, make turns, avoid obstacles etc etc.

Tesla self driving kind of works. In a very similar way to how it kind of worked back in 2016. It's better than it was in 2016, don't get me wrong. But even today they haven't solved the problem and Karpathy left in 2022. And other companies notably have actually surpassed Tesla over that time. I don't think anyone could reasonably say he walked away in 2022 because he thought the job was finished.

> He sort of left OpenAI before it really hit the inflection point

Sorry I'm out of the loop... What inflection point are you referring to?

HarHarVeryFunny 9 hours ago|||
When OpenAI was founded, the mission was to develop AI, but nobody (anywhere) knew how to do AI, so OpenAI did ML research on games instead, which is what DeepMind was doing (with Google's perceived AI/ML dominance being the raison d'etre for OpenAI, and Google having just bought DeepMind). This was the era when Karpathy was at OpenAI.

Around the time Karpathy left, Ilya Sutskever, another OpenAI founder, started playing with Google's new "Transformer" architecture, which was the beginning of the "GPT" series, GPT-1, GPT-2 and eventually ChatGPT (GPT 3.5 + RLHF). In retrospect OpenAI's early Transformer experiments and GPT-1 was the inflection point that moved OpenAI from a company that wanted to build AI, as soon as anyone else did, to one that was actually doing so, although I think it would be revisionist for anyone to claim they knew what they were doing at the time. The early GPT-1 and GPT-2 papers read more like "wow, this is a bit unexpected, look at all of the things it can do!".

Well Karpathy left in 2017, and all the sort of commercial stuff didn't happen till a while later - for example they set up the structure to take external money in 2019 and that's obviously the point at which they'd found the pathway that justified doing massive training runs and all that. So Karpathy was out very early (left at the point that Musk thought OpenAI had basically failed).

I read this as a bad sign for Anthropic. Relying yet again on more hype instead of improving products.

OpenAI’s hiring recently has been much stronger, whether through luck or structure. The “no-name” guys have actual taste. I love that. I don’t care that they’re no-names.

I don’t know Karpathy personally, I won’t speak bad about a man I don’t know. I hope he makes CC better. I just read this as hype. My point is that there’s nothing he has that an empowered no-name product manager doesn’t. It’s like Alex Wang at Meta. That acq didn’t redeem Meta. They actually lost LeCun. Where’s Llama today?

Regardless of what Anthropic’s share price is, OpenAI has been fucking killing it recently. I don’t take particular pleasure in saying that, i’ve been a google and gemini guy for years

My lens is meritocratic. My experience is as an extremely heavy user of both company’s full suite of products in the range of 5 digits per month. My interest is better products not hype.

Joking aside, there are small communities pushing codex and AI to the bleeding edge of what's possible.

Tibo has been impressing me, bc they're building the things these small communities are building.

One of the things these bleeding edge guys and girls have been working on is a /goal feature, essentially ralph loops. Codex released it as a feature the other day. I can't help but be impressed. As an ex-pm, this is product management.

Then you take a look at what the Chinese are doing on their own forums, and it just makes what Google and Anthropic are doing look outdated. OpenAI feels competitive, which I like. What's coming will not be kind to us, we adapt or we die.

What codex is a few steps away from doing is changing fundamentally a lot of workflows.

Remote codex with their computer use is basically you at your computer doing things, 24/7.

Then they added gpt images 2.0

what codex can do, in a few more product iterations, is show you visually side by side “would you prefer this (A) or that (B)” in a series of questions. This is what some open source researchers have been up to. That’s no longer guessing.

I’m not trying to hype a company i have no stake in, but they’ve been killing it.

Yes, he was [1] director of AI and Autopilot Vision at Tesla, directly poached and reporting to Elon Musk on the most important headline feature of Tesla directly managed by Elon Musk.

He had both the technical and executive authority to determine if the product was fit for customer usage. He had direct executive responsibility for the product on the road between 2017-2022.

If he, the lead architect and executive responsible felt the product was dangerous and then he was overridden, he can not get away with claiming he was “just following orders”, he had a moral duty to not sign-off or quit otherwise he is clearly complicit in deploying a dangerous product for his own self-enrichment.

When people talk about engineering ethics, this is literally a completely uncontroversial textbook example. The only way you accept this is if you do not want ethics in engineering.

Furthermore, he was extremely hireable with numerous job opportunitys available to him. He would not be destitute or even particularly worse off if he did quit for ethical reasons. Any self-preservation defense is also invalid.

His goal could simply be to learn SOTA architectures.

When rumors started that GPT-4 design would be kept secret, he likely wanted to know what architecture it would be. Perhaps he left Tesla, waited out the non-compete clause, and joined OpenAI to learn its details.

When Mythos dropped, there were hints that it had a new architecture. He might similarly want to know how it works.

Either way, there is enough cross-lab hiring that those secrets eventually get known, but only by the labs.

interesting signal about where AI is...

It actually feels like a signal that it is in a tapering phase.

As in, if it was in a growth phase a freeform, solo - collab with who you want, would be more beneficial. But in a tapering phase you'd want structure and to be in the private formal meetings.

Or, you could fit the exactly opposite story to the same data:

Growth is when you want to have institutional support, to be at the tip, backed by infinite money and best compute infra, and benefit disproportionally from compounding. Conversely tapering is when you're best flying under the radar, and there's plenty of value both in ideas and in hardware, as the leading players shed excess they can't support anymore, ...
