Karpathy will start this week on Anthropic's pre-training team, which is responsible for the massive training runs that give Claude its core knowledge and capabilities, according to Anthropic.

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.

just an idea

Funny. He foreshadowed this in a recent interview. Saying that he may fall out of touch with evolving approaches and if any of the frontier labs would have him, he’d be interested.

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.

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 their research into something very interesting.

reply
DiscourseFan 2 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.

That implies Karpathy is either dumb or desperate and he is neither of those by a long shot.

noufalibrahim 48 minutes 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.

reply
newppc 21 minutes ago
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. Carmack going to Facebook is a prime example - he joined with the idea of using all those resources to build world-changing tech, and instead he ended up headlining conferences, and fighting a losing battle against the corporate types who were put in charge of Oculus.

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 first 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.

Andrej is a smart guy. You don't get into Stanford for grad school without that.

But he has always been known for his communication rather than his research. He got famous by putting out a (very well made) course on machine learning that was available to the public. Since graduating he hasn't exactly delivered on revolutionary new stuff at the businesses that employed him but he has continued to be extremely good at communicating thoughts about the current and future state of AI. Businesses want that and he knows that he can deliver that.

There are things that you can only explore and learn in those places, for obvious reasons.

I don't know his personal life goals but he's a great communicator and educator, if this decision makes him more up to date, and allows him to create even more relevant content then is something everyone will benefit. I understand the risks of being bias toward one company and not the other, but if you look at the content he created so far, he always talk principle first and specific tool later.

I think people here should give him the benefit of the doubt.

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.

Dude, both! Codex is going to eat Openclaw… i don’t love saying that.

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.

reply
Veserv 52 minutes ago
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.

I can spare a minute :). This isn't exhaustive because this is just stuff I know of, obviously.

- At Stanford, Led research on the first (to my knowledge) crop of joint image/text models. Super widely cited work. - At Tesla, led their whole self driving effort for a while, came up with critical techniques that allowed them to make progress (e.g., the concept of "auto labelling": using a much larger NN to generate training data with which to train smaller models that could fit in the on-device compute. IIRC, Elon said they would not have been able to make progress without this insight).

I'm not sure his educative efforts for the mold of what you're looking for, but if so, the course he designed at Stanford (and availed online):for neural networks, as well as his blog posts, (most famous of which, to my knowledge, is "the unreasonable effectiveness of LSTMs"), made a huge impact on educating a generation of tinkerers and researchers.

Other people sporting struggles to catch my attention longer than the play itself, for that reason.

He is citing R&D? I have always been under the impression that he is an image recognition etc. expert rather than an LLM expert.

So, does Anthropic pivot to military tech or pretend to do so before the IPO?

Or is this simply a deal where he uses his formidable influencer skills for Anthropic and gets to cash in on the IPO?

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

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.

I have been impressed by some of his work, especially on the vulgarisation and simplification. Excellent communicator and engineer. But I am a bit more skeptical about his taste and vision.

Leaving OpenAI to work for Elon Musk was a poor move, and AFAIK his work on CV at Tesla did not bring anything groundbreaking, unfortunately probably the opposite (the bet on camera-only driven system did not pay off) and his talks about the approach would indicate that his whole idea to make it work was nothing more than hill-climbing.

Also, his over-reaction to the whole Claw thing was a bit ridiculous, in my opinion.

I don't see him as a Scientist in the field, but more as an efficient tinkerer.

Not about money, but knowledge. The frontier of the field is no longer accessible through arXiv or research papers only.

One thing is that the companies are holding on because of competitive advantage, and I think another is that AI is such a politically polarizing topic that actually being open about everything is risky for the companies, wanting to avoid controversy.

I worked for MS and Apple for 20 years and heard that opinion constantly; i.e., "People only work there for the money."

I have no idea if Andrej "sold out" but perhaps he realizes that if he wants to work on the cutting edge alongside talented people, with a seemingly endless budget, Anthropic is a good choice.

I chose my employers for the same reason; the compensation was secondary.

Not exactly .. he was at the forefront of computer vision (CNNs, image captioning) for a while during the ImageNet era, then joined OpenAI in 2015 but left for Tesla in 2017 before they released GPT-1. During Karpathy's time at OpenAI they were still working on games. He left Tesla in 2022, briefly rejoining OpenAI, but this was after OpenAI had already released ChatGPT (GPT-3.5), so he missed the first hand experience of the whole AI=LLM explosion.

Recently on the all in podcast, they talked about how Anthropic is probably the next big monopoly. Given how quickly they have been growing and all of the products they are pushing out rapidly, even if they are sloppy, the acquisitions, and the people they are hiring, it feels like that may actually end up being true.

But what is the solution? I don’t think it is safe for a society built on free speech and other liberal values to have a couple extremely powerful companies controlling all our information and imposing their rules and their politics on top of us. It was bad enough under the FAANG companies. This will be worse.

Personally I’m not comfortable with how much power Anthropic is accumulating. And with them partnering shamelessly with Elon Musk to use a datacenter powered by potentially illegal natural gas turbines, I feel like Dario is just not trustworthy.
