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.

Specifically it looks like he's planning to extend the ideas from https://github.com/karpathy/autoresearch into a larger effort towards recursive training improvement [1]:

> Excited to welcome Andrej to the Pretraining team! He'll be building a team focused on using Claude to accelerate pretraining research itself. I can’t think of anyone better suited to do it — looking forward to what we build together!

Am I the only one who wasn’t particularly impressed by AutoResearch? If you looked at what the agent was actually doing, it was just tuning parameters mostly, not really trying different novel approaches.

I couldn’t help myself but consider this mostly a very inefficient variant of hyperparameter optimization, but someone correct me if I’m wrong, I may be looking at this too pessimistic.

lacker 4 hours ago|||
I didn't dig into what the actual repository was doing, but personally, I took some inspiration from the idea after reading about it and realizing that I might have been underestimating the ability of LLMs. I put a bit more work into a performance harness I was using locally and just set some agents to brainstorming and they did seem to find some great stuff. So I don't really have a stance one way or another on this specific repo, but the general idea seems like a really good one.

I'm as jaded as can be but I think Anthropic is now beyond the point where they'd place much value on farming Karpathy's name recognition. I'm sure they considered it an extra plus in his hiring package but they wouldn't do the level of comp package he'd want if they didn't believe the odds were decent that he'll contribute serious value.

Sure, it can always not work out but that's no more a risk with him than any high-profile hire who doesn't really need the money and will always have other options.

>Speaking of, how did he not lose credibility at “full self driving next year, better buy it now”-Tesla?

That I also want to know. He bailed out of Tesla right when the limitations of his "LIDAR-less cameras only self driving" system were becoming obvious, and nobody asked him about the hindsight of this obvious fuckup.

>but as director of AI and auto vision Karpathy bears the responsibility for those features.

Exactly. You lead the R&D, so it's on you. If your boss makes stupid decisions in public overriding your best judgement, the leave and go somewhere where your decisions be respected. The ML market was red hot for people like him back then so it's not like he didn't have alternatives.

Although I doubt Elon forced that idea on him, since he's the one who was confidently claiming that vision only is better since Lidar pollutes the sensor fusion data.

Good for him, his public work these last ~1-2 years has been influential for me, as I'm sure it has for others.

I even share his concern about struggling to keep pace with the rate of change lately, and agree that my working in a frontier lab or any other such environment would certainly help with that!

I have a weird background mix of analytic philosophy, linguistics/NLP, propaganda research, and long-term institutional data science/strategy work, which unfortunately does not make ATS systems especially low-friction as I try to jump industries.

So I keep busy the best I can: lately building tooling around runtime observability, intent legibility, and intervention in LLM systems.

bigyabai 3 hours ago|||
That was probably the first thing they considered. Afterwards, you usually reflect on other "totally smart" executives like Gates, Jobs, Altman... all of whom are both criticized and appraised by their peers in equal measure.

In hindsight, it's easy to assess that Gates was a charming moron, Jobs was an overeager egoist, and that Altman is a sociopathic liar. All of the white knights defending their boy genius narrative are contradicted by their asinine philosophies, and in Elon's case he's simply undermined by all of his broken promises, random accusations and manic paranoia.

Musk being a PoS is a separate issue. My main concern is Karpathy taking about Musk as someone who is smart and makes good technical decisions.

From all the interviews and stuff that came out within the past few years, its pretty clear that Musks only contribution to anything is just throwing money at stuff while also scamming suppliers, governments, and so on. The dude has no technical knowledge of his own, he just lies and lies about what actually happens, and takes credit for accomplishments that aren't his.

When you hear someone who is supposedly smart talk about a dumb person like he is smart, it raises questions on whether that person that is doing the talking is actually smart.

I have the opposite impression. I have consumed tons of hours of interviews with Elon and he comes off as more technically sound and speaks more substance than any other large org CEO I can think of.

Anyone else fearing Anthropic more and more each day? Not from a perspective that they are doing so well, but rather that it's like an industry tornado, sucking up and destroying everything in it's path.
gsleblanc 49 minutes ago||
Yes. I think Anthropic's success with claude code + cowork and the way it's shredding through white-collar work is basically cementing the thesis of Geoffrey Hinton's latest paper (https://link.springer.com/content/pdf/10.1007/s12559-026-105...). I highly recommend reading it in full, but briefly:

1. Copernican Revolution -> We aren't the center of the universe

2. The Darwinian Revolution -> We aren't the pinnacle of life

3. The Freudian Revolution -> We aren't even in control of our own minds

4. The "Intuitive AI" Revolution -> We aren't the only form of intelligence

I think even a month ago I would've read this article and scoffed, but having used Claude Code almost exclusively at work for the last couple months it seems pretty undeniable that in-context-learning and a good enough harness is all you need to displace most "thinking" jobs that require just a bachelors. The hundreds of billions of dollars pouring into data center build-out basically hinges on this thesis, and frankly I trust the judgements of the billionaires financing these deals better than LLM-naysayers on hackernews (not to mention the non-public info they have access to). You don't need to reach superintelligence to still deeply, deeply affect society, and I think Anthropic was the first to build products that are actually good enough and, critically, hands-off enough to do just this. Every day it's clearer and clearer to me that "I was born into a poor family but am relatively intelligent and good at learning things, therefore I can find success" is exactly what will ultimately be eliminated as the outcome of this unless we get the government to step in and regulate.

I could go on and on, but the main point I'm trying to make is that you should definitely examine unease you feel about Anthropic, consider framing that unease in the context of Hinton's argument, and ask yourself what the implications may be.

4. All low-code products/startups

> 1. Figma (in progress)

Hmmm… maybe. I think not. It really depends on your other claims below, with which I mostly disagree.

2. Most entry level jobs for current graduates in white collar fields. (See hiring rates for these positions)

Maybe a small amount. Entry level white collar jobs have a low hiring rate for other reasons, imho.

3. Thousands of layoffs (mostly attributed to AI use, while not 100%, the Anthropic's specific marketing push has a huge influence on this - unlike OAI and other labs)

What they say and what the actual reasons are not the same, imho. Correcting for over hiring is the actual main reason.

4. All low-code products/startups

Low-code and no-code products in the hands of someone who doesn’t have a developer’s mind and/or experience usually ends up as a mess, and quickly becomes an unusable mess.

I know of exactly two people who have done successfully used AI to make a low-code/no-code product. One is just highly motivated and wicked smart. The other did a minor in CS a long time ago (works in a different field). Everyone else shows me a pile of garbage and asks me how to fix it (answer: throw it away and start from scratch).

5. Web agencies who did small websites for local businesses

As with 4 above, the only site a local business can make for themselves is one that functions as a business card… at best. Usually it looks more like a business card that a kindergartner made. They simply don’t understand what makes a website good for their business, therefore they cannot direct AI to make it for them.

There’s a lot to criticize about AI, imho, but these aren’t on the list.

ElProlactin 2 hours ago||
I personally know several digital marketing people who were "tech savvy" but had no programming experience who have launched websites that would have cost them thousands of dollars to build.

So much of what you'd previously pay a "real" freelance developer or web "agency" to build is no less "garbage" than what engineers would call the average vibe-coded web app.

Claude in particular is today really surprisingly good at taking examples and a layperson's description of a website and building something that looks good and is functional.

For obvious reasons, I think many developers/engineers don't want to accept this. They'd prefer to believe that there's something special about their craft that means something produced by AI isn't good enough. But the honest will acknowledge that spaghetti code and crap pre-dated AI.

slyzmud 2 hours ago||
> They'd prefer to believe that there's something special about their craft that means something produced by AI isn't good enough.

I know I can code and get better results than most people can with an LLM but I've came to realize that it doesn't matter and people just want to see results (even if they are kind of wrong).

In other words, with the website example, I've realized that even if the agency can do something 10x better, most people will choose to "buy" the AI website just because it's free or super cheap, and that makes me sad

It will be years before they can bring their own fabs up to speed, but they now understand that a Manhattan Project level of effort is called for, and their AI labs aren't going to drag their feet in the meantime. This is how we ended up with a 27B model that can run with the big dogs from only one generation ago.

You gave two statements which are different from what I quoted.

The idea of "defend[ing] the United States and other democracies" and "defeat[ing] our autocratic adversaries" are always the stated reasons for US military action. Iraq was certainly an "autocratic adversary" and hundreds of thousands of people died from the war there. Vietnam was about "defending democracies" and resulted in millions of people dying. These are atrocities on an incomprehensible scale.

The ethical objection is very simple. War is evil, and the military is in the business of war.

If so, then I suppose they'd say it's fair to condemn the US as evil because deaths have happened, after all.

...and then silently got back to talks with DoD [0] and gave them the Mythos model. Separately, they went back on their promise to only develop models that they can guarantee are safe [1]. I reckon considering which country they are HQ'ed in, building skynet is in their destiny.

Exactly.

This good guy ("AI Safety") versus bad guy is all marketing gimmicks. I'm old enough that it reminds me of Google "don't be evil".

What I find worse is that some people actually believe Anthropic are really the good guys.

You should chat with some people involved in AI safety, if you really think it's a farce.
siren2026 6 hours ago|||
Imagine being gullible enough to think any of those companies would ever chose AI safety over losing their monopolies in AI.

AI safety is important. My point is: you should have zero trust in those companies to actually care about AI Safety besides the marketing and PR aspect of it. Incentives matter.

solenoid0937 5 hours ago||
Dunno, Anthropic delayed Mythos and refused to break their red lines for the DoW. But you seem to harbor this irrational hatred for them and the AI safety crowd so I'm not sure this discussion has much value.

Hypothetically you take the leading expert of a field and say "they believe in their own field too much - far more than I do as a layman - and therefore surely must have psychosis."

Why should I trust that your assessment is correct? Is it likely to ever be correct in the case of a doctor/mechanical engineer/athlete/economist/whatever? So why do so many people insist that an incredibly intelligent AI researcher has fallen into some obvious trap?

Because we're paying attention? A lot of "smart" people are lost in the AI sauce, grandstanding that they are going to change the very fabric of society. Generally leading experts in other fields are not making the same hyperbolic, self-indulgent, embarrassing statements.

At risk of being "lost in the AI sauce", do you seriously believe that AI isn't actively changing the fabric of society? Almost feels like we're living in totally different realities if that isn't clear-cut

I still put my pants on the same way, eat the same food, talk to my friends and family the same way. I drive to the grocery store, pick out the same food and cook food at the same home. Talk to my kids, take them to activities and watch Bluey.

The only time my reality has changed is when I spend time at a computer or on my phone and even then, its a fraction of the total time. So no, it's not a "totally different reality" for me.

Karpathy's career arc feels similar to Jim Keller's; a butterfly flitting from one flower to another, gathering experiences and creating magic everywhere they go.

Like specifically what has he done?

davidatbu 11 hours ago||
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.

HarHarVeryFunny 6 hours ago|||
The auto labeling work (which has been partially described/presented at Tesla AI day events) seems more like engineering than research, a grab bag of techniques that I would guess the whole team must have contributed to. For example, they auto label low resolution/indeterminate objects (image segments) by temporal continuity... Something that is a low-res blob in the distance becomes a hi-res and easy to identify object when you drive by it, so by tracking objects backwards across frames you can learn how to more confidently label the lo-res blob. Things like this are useful, but it's the sort of stuff that engineers and developers are coming up with every day.

You don't think that tracking objects from frame to frame is obvious ?!

I can guarantee you this was built-in from day #1

I'm guessing you're not a developer if you don't then automatically think of end cases like "what if car # 1 isn't in the preceding frame" ... (then you look at some relevant test data and see it was there, unlabelled ...)

Tesla still hasn't achieved their 2016 self-drive goal by their self imposed deadline of 2017, even now a decade later. So, politely, is that accolade merited?

The current vehicles sure seem to come close. I'm not entirely clear on how they've missed this goal, but the current models can do full self driving where I live, including parking.
derangedHorse 5 hours ago|||
How does Elon's arbitrary deadlines impact whether the accolade is "merited"? Incredible progress was made in a fairly short amount of time. His accolade isn't based on his employer's ability to predict delivery dates, they're based on the quality of the systems that are actively deployed today.

Do you mean that the fact that I misremembered a word on the title suggests that I know very little about Karpathy's contributions to the field of neural networks?

Thank you!

I was more looking for signal that him + Anthropic might yield something beyond a step-change from Opus 4.7 (disappointing so far). We have not gotten to use Mythos yet, I wonder if that will become Opus 5 or something.

A viable path to becoming a billionaire or a viable path to build something that met its goal? There are several notable educational content companies that run on quite minimal budgets once they have the platform and other (mostly) capital expenditures taken care of.
