- dakolli 5mo agoHe's a good educator, sometimes. But these days it seems like he's mostly gone of the deep end of being an LLM salesman.
- bigbuppo 5mo agoI would like to announce I've retired. The tech industries are screwed and the future is paper.
- rvz 5mo agoThe big question is... Why now? What happened to Eureka Labs? Maybe the IPO potential was just too great to ignore and maybe AGI (A Giant IPO) is around the corner.
- reducesuffering 5mo agoAGI around the corner. Comparatively little point educating people instead of machines
- whywhywhywhy 5mo agoIf someone knew AGI was around the corner they'd be buying an island and a yacht not taking on a job.
- Sol- 5mo agoBut surely being part of the birth of AGI would be more interesting than sitting on a yacht, which you can do for the rest of your life post AGI?
- whywhywhywhy 5mo agoThe implications of what AGI would do to the economy has a high chance of mass civil unrest. Just the announcement could set it off. If you had the resources you won’t want to be around for it.
- f311a 5mo agoPressure, a lot of researchers believe LLMs will be able to self-improve. It's a good time right now to make some extra money. I, personally, don't think there will be a better time for researchers to make so much money in a few years in any future of LLMs.
- enraged_camel 5mo agoPretty big talent win for Anthropic. Karpathy is one of those people who was working on AI before it became "a thing," and he's definitely both a thought leader and influential practitioner today.
- HarHarVeryFunny 5mo agoNot 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.

- Barbing 5mo agoAndrej Karpathy - @karpathy Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time. May 19, 2026 · 3:05 PM UTC

- philipwhiuk 5mo agoAnthropic just bought compute off XAI so he's more tightly bound not less.
- Barbing 5mo agoThat’s a gift to both parties there, yes they sure did (ghosttown Grok servers will get some use, Claude customers able to do things such as… using the service) Karpathy’s so smart and he has to deal with the reply quality we see on XCancel there… one click away from Hacker News and suddenly every reaction is trash instead of insight and deep insight we see here (Plus the trash I post, but we’ve got some range, not monotonous spam & model output)
- skywhopper 5mo ago“ghosttown Grok servers will get some use, Claude customers able to do things such as… using the service” … Memphis/Southaven residents will get more air pollution.
- yanis_t 5mo agoGood for him. His learning materials are unmatched, but I don’t think there was a viable path with his educational company.
- munk-a 5mo agoA 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.
- aizk 5mo agoAI news and ESPN feels interchangeable sometimes.
- ssgodderidge 5mo agoAgreed! OpenAI even bought TBPN [1], who many have equated to ESPN for business. I think that even if Karpathy didn't add any new ideas to Anthropic (unlikely), adding him to the team is an interesting message to give to the market [1] https://openai.com/index/openai-acquires-tbpn/ https://openai.com/index/openai-acquires-tbpn/
- Danox 5mo agoMaybe he adds some semblance of stability? Anthropic probably is trying to sell it itself as the sane alternative to OpenAI with their IPO coming up choose us we are responsible.
- clickety_clack 5mo agoI’ve never seen names be big in the industry in this way before. It used to be founders, now it’s personalities.
- TeMPOraL 5mo agoAt least in this case we're talking about someone doing something useful and providing tons of value to the field, not about people being praised for starting a company and raising money.
- sph 5mo agoI'll reserve judgement until I've heard what ThePrimeagen and simonw have to say about this.
- christophilus 5mo agoThis gave me a good laugh because we don’t know what to think until Jon Blow says, “Here’s the thing.”
- dwa3592 5mo agoKarpathy is talented and to me he always seemed like someone who would be against building something like skynet. Anthropic is lucky to have him.
- cute_boi 5mo agoHonestly, if Skynet were possible, Anthropic would probably build it first and claim they had to because OpenAI is bad.
- scottyah 5mo agoAnthropic has drawn lines with the most powerful organization in the world, that OpenAI capitulated on within hours for a small contract.
- dwa3592 5mo ago100% and that was bold and set a good example, at least from the outside.
- actualwitch 5mo ago...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.

- scottyah 5mo agoLines drawn does not mean "refuse all communications". They were very clear that they wanted to continue the partnership, but adhering to the terms of the contract. I personally think that is the best stance- support the good work and avoid what they deem as bad.
- amazingamazing 5mo agoMoney always wins.
- bell-gwen 5mo agoTrue.
- Sol- 5mo agoCome on, he definitely has more money than he needs given his past employers. For someone with his creative output, he probably just enjoys having an environment to build and explore.
- moralestapia 5mo agoYour argument contradicts itself. If money was not an issue he could just build that environment for himself.
- CooCooCaCha 5mo agoDo you have any idea how much it costs to build a frontier model and how much money it takes to enable R&D at the cutting edge?
- HDThoreaun 5mo agoNo, money is not the only barrier to building things. I think karoathy could build his own lab if he wanted, but it would be years of doing things he doesn’t want. Why waste time running a business when he’d rather be researching?
- 0123456789ABCDE 5mo agoi can play by myself, or i can join some friends, and make the play more joyful
- skeledrew 5mo agoThe overhead of maintaining and running things isn't interesting to most creative folk. They'd rather others deal with the minutiae (managing a company, etc) so they can focus on their thing.
- bell-gwen 5mo agoWell, I am listening.
- ryeguy_24 5mo agoFunny. 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. https://youtu.be/kwSVtQ7dziU?t=47m50s https://youtu.be/kwSVtQ7dziU?t=47m50s
- skeledrew 5mo agoSomeone at Anthropic watched and lit a fire.
- ineedasername 5mo agoGood 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. Some small public artifacts finally going up: https://huggingface.co/spaces/anotheruserishere/Cartogemma https://huggingface.co/spaces/anotheruserishere/Cartogemma Eh. Worth a shot!
- gopher_space 5mo ago> 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. There's a choice to be made between helpfully defeating someone's ATS and searching for more clueful employers. I'll probably be walking paper resumes into local offices next time around anyhow.
- cbm-vic-20 5mo agoI wonder if he had to answer a few Leetcode / Codility problems first.
- etdznots 5mo ago[dead]
- markerbrod 5mo agoI 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 https://x.com/EurekaLabsAI/header_photo), incredible how much GenAI has improved since that image was created.
- ablation 5mo agoCringe? Some of those background faces are utterly horrifying. Or maybe he's trying to tell us something by populating a future world with skull-faced mutants.
- bilsbie 5mo agoHe should have done his own lab. He seems like someone capable of it and might bring some unique ideas.
- JumpCrisscross 5mo ago> He should have done his own lab Which raises the question: what can he do at Anthropic that he couldn't on his own?
- TrackerFF 5mo agoSeems 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.
- JumpCrisscross 5mo ago> you need incredible amounts of money to be competitive in the frontier model arena This is my assumption. > 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? 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.
- skywhopper 5mo agoMake a lot of money.
- shuckles 5mo agoHe can be at the frontier while just having a regular job. Every other option is a lot more work.
- ciwrl 5mo agovery interesting news... we are living in exciting times.
- deleted 5mo ago[deleted]
- Traster 5mo agoKarpathy 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 5mo agoi 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
- canada_dry 5mo ago> just becomes a glorified marketer That implies Karpathy is either dumb or desperate and he is neither of those by a long shot.
- prodigycorp 5mo agoi mean he did publicly openly solicit interest to work at a frontier lab so he can be closer to what's going on https://www.youtube.com/watch?v=kwSVtQ7dziU&t=2870s https://www.youtube.com/watch?v=kwSVtQ7dziU&t=2870s
- alfonsodev 5mo agoAnd it makes a lot of sense, doesn't?. 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.
- 423abaf 5mo agoHe 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?

- misiti3780 5mo agogo away. this isnt reddit
- ryzvonusef 5mo agoKarpathy'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.
- ambicapter 5mo agoI don't think Karpathy has nearly the portfolio of accomplishments. I think of him more as an educator.
- kingkongjaffa 5mo ago> creating magic everywhere they go Like specifically what has he done?
- davidatbu 5mo agoI 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.
- kingkongjaffa 5mo agoThank 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.
- 5mo ago
- mellosouls 5mo agoKarpathy is a terrific communicator and populariser of the LLM landscape, and I do hope this isn't going to mean his work in that regard now gets dropped, or dropped into a private Anthropic-only void.
- jaccola 5mo agoI mean he is basically an influencer at this point? I guess this is a marketing play and we will be hearing more from him than ever.
- twsted 5mo ago[dead]
- bicepjai 5mo agoGreat communicator. It’s sad that he had joined a closed llm org. I would have expected him to join forces with someone else releasing open-source models rivaling chinese model landscape. Capital always accumulates to the capital holder in capitalism :)
- frellus 5mo agoSort of makes me sad, but . . . everyone has a price.
- helloplanets 5mo agoNot 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.
- LatencyKills 5mo agoI 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.
- surgical_fire 5mo agoMS and Apple. Infinite resources, plenty of smart people that consider compensation to be secondary (I remain skeptical, but choose to entertain the idea nonetheless), and the software output is incredibly, unbelievably, comically bad. There's some poetry there that I am unable to capture with words.
- Barbing 5mo agoApple’s software defects can be comically bad. Software overall though, you may overstate.
- LatencyKills 5mo agoI understand where you are coming from, but at least when I was there, we were still trying to develop solutions that had never been implemented at that scale before (just like Anthropic today). I helped create the first version of Visual Studio (Boston). People tend to forget that even by the 90s we still didn't really understand how to solve a lot of the main technical problems. That's what I loved about the work. Everything seems easy/obvious after the fact. When I left MS, a full Windows build was about 18M LOC. The fact that 18 million lines of code, written by tens of thousands of engineers, worked at all was a mini miracle. With regard to compensation: like Karpathy, I had already earned enough to be comfortable for the rest of my life. Once money stopped being the primary driver, I was able to focus on what made me happy. Building things, even if you don't like them, brought me happiness and fulfillment. I hope Andrej finds the same at Anthropic.

- stephc_int13 5mo agoI 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.
- ausbah 5mo agoi think his “fame” in the past few years has been creating teaching materials, projects, etc with lots of nuanced informative takes around the LLM space
- annexrichmond 5mo ago> the bet on camera-only driven system did not pay off This is a pretty unsubstantiated claim. Tesla is now launching robotaxis at a fraction of the cost of Waymos, in part because they don't need all the Lidar.
- stephc_int13 5mo agoLet's say it is an opinion. But Tesla has been promising full self-driving "next year" for quite a long time now, and it seems they are stuck at the "95% there" stage basically forever.
- kranke155 5mo agoTesla will crack it, I expect, just much later than Waymo. But Waymo cant optimise their own robots. I expect the cost and knowledge curve to rapidly go agaisnt Waymo eventually. Being able to build the robotaxis at scale is a huge advantage. Im no fan of Musk.

- make3 5mo agoThat's a funny thing to say as time is infinite, and we're at the early stages of every single thing. Reasoning in time dynamics is useful though to be clear

- deleted 5mo ago[deleted]
- SilverElfin 5mo agoRecently 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.
- eieiewq 5mo agoImagine taking their word as gospel lmao.
- orliesaurus 5mo agoAnthropic is on a roll: - best harness overall (well maybe until like a month ago when gpt5.5 and codex came out) - acquires bun - acquires stainless for SDKs - deal with Elon for compute - karpathy what else did I miss?
- nashadelic 5mo agothey invented MCP, Skills, made these standards open so anyone could build the harness around them.
- orliesaurus 5mo agothis pre-IPO is gonna be incredible
- munk-a 5mo agoIt's going to be dramatic - it's unclear how much of their DAUs are organic and how much is through their PE usage deals. There's a large amount of organic usage certainly, it's a useful tool, but there are quite a few of the tell tale signs that they have an internal number they want their user acquisition to be at and they're failing to meet that through organic growth.
- orliesaurus 5mo agoI have this image in mind [1] - I wonder how it shifted over time. [1] https://imgur.com/a/3zBZ27I https://imgur.com/a/3zBZ27I
- bigyabai 5mo agoTo be fair, MCP and Skills do not have any source code. It is fundamentally impossible to release either standard without making it open.
- xmcp123 5mo agoMCP is barely an invention. It's a fuzzy spec detailing a pretty obvious design pattern.
- wg0 5mo agoImmense respect for Karpathy but are these people that optimistic about AI? I mean short gig, few million dollars for Karpathy so makes sense for him but others should read the Cloudflare's report about the super scary model that Anthropic wouldn't release because they love humanity more than their balance sheet.
- MangoCoffee 5mo agogood name recognition for Anthropic mega IPO. everything Anthropic does now is all gear toward its IPO from buying Bun, Stainless, getting big name AI guy to join...etc.

- Cupprum 5mo agoWhat does PoS mean?
- its-summertime 5mo agoin this context, "piece of shit"
- joeyhage 5mo agoThere’s a lot of nuance to this. Regarding the former, what if someone used unethical or illegal means to produce the work? And regarding the latter, we can choose to provide constructive criticism out of kindness. Apathy or silence is a disservice to others in some cases.
- ActorNightly 5mo agoMusk 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.
- zitoshi 5mo agointeresting 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
- TeMPOraL 5mo agoOr, 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, ...
- zitoshi 5mo agoYes, that makes sense. But to your point, then the growth is not in the ideas that can be generated with AI, and more in the structure. Which feels like a different stage. Maybe "growth", wasn't a good word.
- KeplerBoy 5mo agoFeels like the opposite. Stuff is still happening and you need to be part of a big lab to see it. NanoGPT is fun but at some point you need that datacenter.
- zitoshi 5mo agoI would guess he's never left out at whats happening, because he's still highly connected with those people even when not at the company. I also feel like there are many ways he can access compute for use of his own ideas.

- stingraycharles 5mo agoAm 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 5mo agoI 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.

- nightski 5mo agoAnyone 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.
- m3kw9 5mo agoWithout Karpathy, the AI field hasn't skipped a beat, but he is certainly a great addition to any team.
- raincole 5mo agoName three things they destroyed?
- ray_v 5mo ago1-3) my free time (too busy using Claude Code)
- nvme0n1p1 5mo ago[flagged]
- raincole 5mo ago1. Bun is right there on Github. You can download can use it right now. 2. Sure, that's one thing. 3. Coefficient Bio is not a thing. They don't have a product. Ever. It's just Anthropic hired 10 people for a ridiculous amount of premium bonus. (Time will prove it's a bad decision, btw) 4. (snorts)
- ahknight 5mo agoI believe the Bun reference is the Rust "rewrite" that came up recently.
- srigi 5mo agoNot yet, but soon… Bun
- gdiamos 5mo agoSmart move
- NoImmatureAdHom 5mo agoAndrej: Guys, thank you for the interest but I'm really focused on this education thing rn Anthropic: Okay, let's add two zeroes Andrej: I am very excited to join Anthropic! (I do not blame him, I think this is reasonable, I find the whole money-falling-from-the-sky thing amusing :-)
- lysecret 5mo agoHonestly happy he’s back at a foundation lab. He will have insane impact there. Of course one of the best educators in the world it’s a bit sad he gave up building and education tool.
- baigy 5mo agoCongrats to Karpathy. I wonder whether this is the right time to join Anthropic. Looks like it from the outside. But - unpopular opinion - I believe Anthropic is one open-source model away (that can code well) from a massive revenue/stock crash. We're already seeing Claude's cost escalate to astronomical levels. Most coding work is medium difficulty in the grand scheme of things. So the future is an open source model small enough to fit in your local 16GB VRAM, giving you a Claude Code like experience for zero token cost. That's going to wipe out most of Anthropic's current revenue base. It does have several cool initiatives in the pipeline, but bad things happen once your bread and butter is threatened (just ask OpenAI).
- nekooooo 5mo agothose models are light years away from opus or sonnett right now though -- is the context problem really solvable?
- zackangelo 5mo agoabsolutely not, take Kimi K2.6 for a spin
- codemog 5mo agoGLM 5.1 is almost there. These guys should be scared. The valuations these companies have is insanity.
- ahknight 5mo agoNot in extended sessions, I've noticed. It's good at targeted edits, but not "build a small tool that XYZ".
- ahknight 5mo agoModel diversity is really their weak point. OpenAI has embeddings, audio, image, video (RIP). Anthropic has ... Claude. It's a great model for a lot of things, but it's super risky to just have one thing you're good at (from a business standpoint).

- domrdy 5mo agoCongrats Andrej. Let me know if you are looking for someone to take over Eureka Labs. We were in the same WoW classic guild. domrdy on x. We can duel for it :). Also, I need $10M if any VCs are reading this.
- HarHarVeryFunny 5mo agoI wonder if the timing of this, coming so soon after the Musk/Anthropic data center deal is just coincidence or not? From Karpathy's various interviews I get the impression that he wants to leave the door open to working for Musk again at some point, perhaps on TeslaBot. With Musk for now regarding Anthropic as a partner (or at least an enemy of his enemy), that seems to mean that Karpathy joining them is less likely to anger Musk than might otherwise have been the case. Who knows, maybe Karpathy was involved in brokering this data center deal?
- trollbridge 5mo agoIf anything, sounds like Karpathy wanted a whole datacentre, and now he's got one...
- photochemsyn 5mo agoLooks like the one sector of the commercial AI world that will outlast the open source - local hardware transition is the military-industrial sector. I wonder what kind of classification-security rating is needed these days for onboarding? “According to reports from The Wall Street Journal and The Guardian, the AI model Claude, developed by Anthropic, was used in the initial U.S.-Israel military operations against Iran in late February 2026. The system, integrated into a platform developed by defense contractor Palantir, assisted with intelligence analysis, scenario planning, and targeting for strikes that resulted in the death of Iran's Supreme Leader, Ayatollah Ali Khamenei” https://biggo.com/news/202603032121_Anthropic_Claude_AI_Used_in_Iran_Military_Strikes https://biggo.com/news/202603032121_Anthropic_Claude_AI_Used...
- 1970-01-01 5mo agoHe 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.
- renecito 5mo agorest & vest if he makes it to IPO
- Yajirobe 5mo agoI wonder what's his net worth - probably 100M+?
- seattle_spring 5mo agodidn't FB grant someone else $1B over 4 years or something for some AI lead role? Wouldn't be surprised if this guy is getting similar offers, which could explode even further with the stratospheric valuations of top AI companies.
- United857 5mo agoHe’s a founder of OpenAI —- likely a billionaire if he held on to his share
- trollbridge 5mo agoIt's still quite interesting to me how a founder of a nonprofit can become a billionaire by having shares in it.
- nikcub 5mo agoBecause they later founded a for-profit to raise the capital required in the AI talent and compute race.
- daft_pink 5mo agoLooks like they sprinkled their ipo money on him.
- chrishare 5mo agoSelfishly, I hope this doesn't reduce to 0 the amount of time he spends doing educational content, which seems like a particular strength of his. I presume this means Eureka Labs is not releasing any product or course.
- thoughtpeddler 5mo agoWondering what the plan is to steward Eureka Labs, LLM101n, and whatever else was being cooked up. As a fellow educator, was very much looking forward to seeing how this would have evolved things.
- maxnevermind 5mo agoAndrej has decided to become a billionaire. Anthropic keeps preparing for the IPO. I wish they IPO soon, let everyone see how the earnings look like.
- aykutseker 5mo agothe glorified marketer framing in this thread is missing the bigger signal. karpathy publicly pausing eureka labs to join anthropic is an ai founder of his caliber effectively conceding that verticals get eaten by frontier upgrades.for everyone here building on top of foundation, that's the actual news
- aabhay 5mo agoHow serious was Eureka labs anyway? It seemed like essentially a banner for him messing around with content creation
- deleted 5mo ago[deleted]
- achierius 5mo ago"that's the actual news", "the bigger signal", etc. -- this has a lot of the hallmarks of AI generated text but with overt stylistic simplification layered on top (nocaps, some weird spacing)
- trollbridge 5mo agoI mean, who hasn't put "stop using emdashes" into their prompt yet?
- lvl155 5mo agoI think this signals game over in the arms race.
- taco_emoji 5mo agoAnd now, a message from an actual deck chair on the Titanic
- syngrog66 5mo agoI have respect for Karpathy. Not for anyone who made Claude or promotes it. So this is a shame. But I can't fault anyone for accepting an offer with (I assume) lots of 0's in the dollar part.
- AtNightWeCode 5mo agoHope he can teach Claude how to not be so lame at coding.
- daneel_w 5mo agoThis just in: AI Superstar tweets about new stint. Crowd goes wild. News at eleven.
- tdiff 5mo agoInteresting if his educational startup turned out to be less perspective at least with the current gen of llms.
- jorisw 5mo agoThanks for introducing me to xcancel
- skyblock500 5mo agoIt feels like every single tweet he makes is a hit
- themafia 5mo ago> I remain deeply passionate about education and plan to resume my work on it in time. "However, it turns out, my deep passion can easily be put on hold with money. Also I'm not really sure what the definition of passionate is."
- lloydatkinson 5mo agoDoes this count as news now on HN?
- loxodrome 5mo agoI can't help but feel like someone with Karpathy's experience and financial resources would start their own company if they had real creativity and vision.
- zulban 5mo agoNot everyone wants to manage a large company. Sounds like a nightmare to me.
- travisgriggs 5mo agoAnyone have any stats on just what the headcount is at Anthropic and OpenAI these days?
- atlasagentsuite 5mo ago[dead]
- ed_balls 5mo agoMeta: Why 1000 votes?
- SequoiaHope 5mo ago1000 people think it’s a cool story. (I am one of them). I like Karpathy and I like Anthropic and I’m excited to see them together.
- travisporter 5mo agoSir, please make it easy to break the twitter/x moat. Why don't we have an app that just posts to all the socials like bluesky/mastodon/threads etc
- monegator 5mo agoI will never get why anybody wants to work for FAGMAN. It's depressing how many talents put money above integrity. You don't need to live in the bay area, most civilized places on earth let you live a comfortable life with a 10th of the salary, plus you are not selling your soul. We are doing interesting R&D in other fields too, in places you would never believe.
- prinny_ 5mo agoFor people like him who probably already have enough money it’s probably just chasing the opportunity to work at the bedding edge of the field he loves. And maybe get to be the father of AGI.
- monegator 5mo agoI get having the opportunity to do research, the problem is for whom. Do you really want to be the person that hands this kind of tech to corporates? Or that does anything to benefit those corporates?
- turzmo 5mo agoGenuine question: how is working for Anthropic selling your soul?

- snakajima 5mo agoKarpathy is so valuable as an educator to the whole world, and I wish he continue to communicate with us after joining Anthropic. Just concepts like "Software 2.0" and "Vibe Cording" are priceless!
- w2seraph 5mo agoBravo Andrej
