Claude Fable 5.2 and Mythos 5.2(www.anthropic.com)
780 points | 920 comments
mirmor23 2 hours ago|
> As an experiment, one Anthropic engineer gave Fable 5.2 the task of designing a prototype operating system. Starting from an empty folder, the model coordinated over 1,000 subagents, working around the clock for eight days writing, testing, and reviewing code. It produced a working operating system that boots on a laptop, with its own core that runs the machine, drivers for the disk, keyboard, and network, permanent file storage, windows, a login screen, an installer, and built-in Claude functionality (see the video below).

As impressive as this sounds, whether it is tech teams or agent farms, the progress slows down considerably as the codebase grows. The real pain was seldom about shipping v1, but was more about how the v8 scales and how easy it is to get there, how robust the system remains between versions, and how constraints are held.

A huge part of the challenge is to pick/choose the design and implementation strategy that can only come from experience. That is one of the primary reasons why it's an absurd advice to me to let the llm do the goalseek and freestyle. This may be a no big deal on microservice or any managed runtime software that is an update away, but on an embedded or a high availability system where the field upgrade and hardware replacement costs could bankrupt a business.

if llm designed a circuit, will you bankroll it?

There's been some discussion around Shopify (and others) move from React Native to purely native and that leading some people to conclude that LLMs have effectively killed RN. Which has always seemed silly to me for 2 reasons: First, Shopify almost certainly has on staff (or access to) actual native devs to steer that ship that a small/medium-sized company may not have. But more importantly, it's not the "Translate this RN app into native" that's the trouble. It's the hundreds and thousands of additional iterations you'll have to do on top to maintain and build out that product.

It's hard keeping separate code bases with separate languages in tandem, and while LLMs definitely aid in that area, I can't imagine it's a free lunch.

We moved one of our apps away from RN to SwiftUI and Android (Jetpack Compose). The binaries are way smaller, and the apps work beautifully.

So I don't see any reason to stick to RN, when we can just use any OS native APIs to our heart's content and our apps automatically feel more native.

They also seem to be ignoring the realities of modern app store reviews. Apple and Google are only getting slower as vibe-coded apps flood their marketplaces with submissions. Maybe Shopify has a special relationship that gets them faster reviews, I don't know. But if not, the ability to put out updates, rollbacks, and hotfixes without being gatekept is a critical feature. Especially with today's security landscape. React Native now seems more compelling than ever before.

What makes you think you can circumvent the App Store to update React Native apps?

From what I heard, updates for many established developers, even individuals, go through within a few hours.

I'd also love the ability to take back control over my rollouts, but with Apple's recent crackdown on remote controlled feature flags in response to fraudulent nudification apps, I'd be very careful about this.

Rumors say Apple now uses heuristics to detect feature flags in the binary. While that's not directly relevant to remotely delivered JS, I fear that bypassing App Review in this way could become a quick ticket to account termination.

While this unattended example is impressive, this is why you need to guide things more closely and make sure the design is itself scalable and maintainable. Otherwise you can get wad-o-slop.

Same thing happens in many cases with junior or mid-tier programmers slung at a project without supervision.

Indeed, I'm curious how much better/worse one human with "one agent" could do that same functionality in a OS from scratch. Last time I did this exercise, I took Cursor's shitty attempt from "millions of lines of source code" to about ~20K (https://emsh.cat/en/one-human-one-agent-one-browser/), and seemingly one of my conclusions still hold true ~1 year later:

This is something I've been thinking about more and more. Since Opus 5.5 came out, I feel we've crested the hill and the answer for "who's going to maintain this slop going forward" is obvious - the LLMs will. Whether or not its slop, is extensible, maintainable, or forward looking almost doesn't matter anymore. Does it solve the problem today? If so ship it, and use the agents to solve the future problems. I am not quite sure this is a good idea, but assuming LLM progress doesn't stop means its probably the bet I would take.

I watch a YouTuber who is homesteading and builds everything. Often times I see him doing things in ways I know will break or fail eventually, but it doesn't matter because he is there and will fix it when it does. You could argue this is a waste of energy, and for a human it might be. For an LLM however I do not think it is.

I’ve had a chance to use fable 5.2. Some observations:

- Anthropic is finally well balanced across models. Meaning: Opus 5.5 is so good that I do not feel Fable FOMO as I did when it was Fable 5/5.1 vs Opus 4.8/5. And Sonnet 5.5 sometimes makes me forget about Opus.

- Fable is good, but you really have to push the ambition of your prompt in order to see proper separation from Opus 5.5. I personally have a hard time telling the difference between Fable 5.2 and Opus 5.5 for ordinary coding tasks.

- It’s way faster and more reliable: one of the worst things about fable 5.1 was how slow it was an, on top of that, how frequently it would suffer from max output token overflows. I got none of these issues with 5.2.

- Fable is exceptional at drawing. It’s ability to render an image with JavaScript actually has me questioning the value of dedicated image models. I prefer the images I’ve gotten fable/opus to make for me over those from gpt-image, it’s wild to think we’re at this point.

> Fable is good, but you really have to push the ambition of your prompt in order to see proper separation from Opus 5.5.

I love seeing this verbalized. We are pretty much at the point that increased model capability will only have utility to folks that are willing to let go of even more understanding of whatever the model is producing.

The best models can/will produce a year's worth of output that would take several days to weeks to properly understand in the span of an afternoon.

For everyone that still wants to feel like they own the end result, just use the lesser models with less ambitious tasks.

Caveat: I think this mainly applies to coding. I would still like the best models possible to be working on e.g. new drug research to cure our various ailments.

If you liked this phrasing as much as I did, here’s an article that might resonate a lot with you:

https://danluu.com/ambitious/

In particular, footnote eight:

> This is not a claim about the future. Perhaps almost all or perhaps even all of the software skills I have will become irrelevant in the near future. But we're not there yet. At the moment, programming skills seem higher leverage than ever before.

> There's something a bit funny about the current moment, where it seems like having the skills that models are replacing makes one much more effective than people who are trying to use models without having those skills. I like Max Bittker's framing that models are very good at counterfeiting and the level of expertise it takes to distinguish a counterfeit from the real thing has been increasing as models improve.

As well as this section fairly at the start:

> As far as I can tell, these problems are problems because people are implicitly carrying around a pre-agentic cost model. Ten years ago, the kind of person who implemented a new compiler because their compiler was slow was the kind of person who started programming a new 3d game engine when they wanted to make an indie game, i.e., the kind of person who never ships anything. Most productive programmers I know still have an aversion to this kind of thing, even though it is now actually reasonable to implement this kind of thing now.

Of course, at the moment everything’s still a bit very much difficult to tell, but “productivity”, at least in applicable areas of work, might really come down to who can let go of the most understanding the easiest? Incredibly thought-provoking stuff.

“might really come down to who can let go of the most understanding the easiest”

I suppose it depends on the “applicable areas of work” but I would argue the opposite. As in all things, when you level the playing field, in order to stand out you have to know the rules to understand how to break them.

Imagine a fully autonomous Ad agency that creates unique ad campaigns for companies. And have it controlled by someone who “let go of the most understanding.” For instance, maybe a business minded person with excellent technical skills, but doesn’t know how to copy-write and has no visual design training.

Even with the strides in AI advancement, this is an impossibility and I’d argue it won’t happen within the next five years even. You need human agency, and you need human workers who are experts in their field.

Those don't seem like mutually exclusive statements to me. In fact, they feel like two sides of the same coin. It's almost by definition that more advanced control systems are exactly the ones where tractable sources of error (mechanical, environmental, etc) have been eliminated, controlled or otherwise accounted for as much as possible, to the point that the only remaining likely problems come from where the system interfaces with humans in some way.

Which makes those interfaces the most critical parts of the system.

It is not. And there is nothing thought-provoking about the mere act of doing heroin.

I, well, agree. Of course the statement is nuts, especially so once you consider issues like vendor lock-in, the oncoming atrophy of one’s own skills, etc. But if you define “productivity” as short- to medium-term results only, is it really that inaccurate?

Good point, not having to plan for the long term probably has an outsized effect on a given level of difficulty/effort required.

Maybe it’d be interesting to see what could be achieved responsibly by motivated people with models in a world without “feature pressure”/competitive stress (which’d include e.g. no security race and infinite attackers and exploits to keep up with)?

Then there is these other programmers who built their own operating systems even though their OS professors are claiming publicly their design sucks, who built a local database from scratch in C because his use case did not need the client/server stuff but just all the other relational goodies, or who built video streaming/transcoding software from scratch just because they have ideas and then the world changes around their ambitions.

I think it is not enough to be ambitious or have the technical ability if you want to build something for others to use. You definitely need deep commitment but also perseverance in the face of social adversity. I think this is what saddens people with automation of the technical aspects of programming. It leaves the more psychological aspects as challenges which are not easy to face all the time.

Great point. Coding used to be a natural forcing function for prioritization of features. When coding is basically “free” you have to do the harder job of saying no to things, deciding exactly what to build, etc…

Well, in retrospect I don’t like this framing all that much either, but I think I came to this conclusion due to assuming

not caring about the output ~ more output

… which may or may not be useful in the long term, but definitely does help a shorter-term “productivity” measure.

On the other hand though, there’s a pretty damning example against my case here: Say a manager of individual contributors – which is what the situation of an individual with sufficiently smart models and tooling may almost boil down to – didn’t directly care about the output anymore. We’d most likely call that being unhinged/unproductive, too…

It was late at night and I primarily wanted to link the somewhat relevant article, maybe I should have left everyone to reach their own conclusions instead of adding some poorly-worded unfinished thoughts. :x

I cannot see it being a good thing to "let go" of understanding. If you don't understanding anything, then why would anyone keep you around? An example hypothetical situation is, if I have a colleague that outputs a bunch of productive things, but they don't understand it, and I do, then of what use are they? I have LLMs too and also have the understanding.

It isn't clear to me why people are so comfortable with letting go of understanding. And it's a bit bizarre because it always seems to be framed as "you're going to get left behind if you care about understanding". I also never hear or read anyone who has any real and deep experience say these things.

fullofideas 11 hours ago|||
My read of what is being suggested is that the level at which one should aim to understand and be comfortable with is slightly more abstract than reading the code and reviewing every line of it. It is like how one is comfortable not understanding the byte-level code or assembly language code. I know that this analogy doesn’t hold very well because compilation is a deterministic process while llms are not, but that is precisely the point being made. “Trust” that llm will produce the right output, even though the output might not be reproducible word for word the next time you give the same prompt.

To your point about becoming redundant without understanding, not understanding things will be a problem when an issue arises and the other person isnt able to handle it the right way. However, if llm can address the issue, does the fact that they did not understand the details really matter? From the perspective of a person who gets to decide who gets fired, would they fire someone who is productive but sometimes introduces bugs that they quickly address or would they fire someone who is comparatively slow but rarely introduces bugs? The answer probably depends on the domain, and how costly a bug can be. For most of us, the work is not so critical that you cannot afford bugs. So, productivity wins.

If you are suggesting humans before LLMs rarely introduced bugs, you probably haven’t got the latest models to review your old code. It’s shocking how many bugs we had before but couldn’t see!

Don't shoot the messenger, but maybe the idea is this:

You're smart, and you know what can go wrong, so you use models slowly, and you check their work. Your bet is that it will make a bad mistake.

Your coworker is reckless, they don't know or care what can go wrong, so they use models quickly. Their bet is that the model won't make a bad mistake.

If the model doesn't make a bad mistake, your coworker is creating more value to your employer, and your employer doesn't really care if you understand the code. They just want something that works.

Over the last year, it sure seems like models are making less mistakes, so the expectations on the bets are changing too.

Right or wrong is this the future we want? Shouldn’t we say and do something?

For instance: we have calculators. We’ve had them for decades in their “current” form more or less. They are readily accessible and far more reliable than LLM’s - if you a problem 1000 times it’ll be right 1000 times, the rare bug or glitch notwithstanding. But we still teach people basic arithmetic. We teach times tables. We didn’t just offload basic math.

I agree we don’t need to know assembly to use a computer but there is a balance here and companies do not care about a balance.

I think we mostly DID offload basic math, for better or worse.

For software engineering I don't know the right balance.

I've used the "we mostly stopped caring about machine code generated by a compiler; maybe we should stop caring about LLM-generated code as well?" analogy myself.

But even I have to admit there's two big holes in that analogy: if I use a compiler to turn C into machine code... (a) compiler bugs are orders of magnitude rarer than LLM-generated bugs (b) my C code remains the source of truth, or at least source of intent. Whereas with LLM-generated vibecode, there's no source of truth, just an ever-evolving mudball. I (kinda?) like the ideas of "documentation as source of truth" and/or "tests as source of truth" ideas, but I don't think we're nearly at the point of viability.

TL;DR yeah I think actual understanding of what LLMs produce is gonna be important for the forseeable future

I didn’t say we were universally good at it but in many countries we are (more or less) all exposed to it and taught it in school. There is a baseline even if we are far from mastery, and frankly a cynical hand wave of “well everyone’s bad at it” is not a real argument. In the US it is very clear that people are at least exposed to it and if we weren’t we would be operating very differently. I went to dinner last night, everyone did the tips in their head right there at the table. The average person can do some simple multiplication and division in their head. It’s not a mysterious script done on a box that they repeat the output of. Most people even if they’re bad at it understand the fundamental concept and, gun to their head, could probably do a series of very basic math problems with pencil and paper.

I imagine you and most of your peers can calculate a tip or at least approximate it without pulling out their phones yes?

This is just moving to a higher level of abstraction. Nowadays people don't verify the compiler generated assembly code anymore. We don't care if our source generates a few million extra instructions. Source code is just an intermediate between specs and binary at an abstraction level decided by the developer. We do requirements -> code -> assembly.

To resolve this we should aim for a new intermediate format that is more high level than source code, the generated code is too monotonic to properly review manually. Something like requirements -> detailed specs for llm -> code -> assembly . Then let one agent implement the specs and have another review it. If we stay at the current abstraction level, humans become the major bottleneck.

I feel like the real value is in probing the extents of your own understanding. If you don't understand something it's doing, you can ask. You do kind of move up a level of abstraction, from the IC to a PM or team lead. So maybe you don't know what every line of code does but if you understand code and how to drive you can trust that it's doing the right thing and you don't have to be as deep in the weeds of every refactor etc.

You do have to keep a sense of when it did the wrong thing and how that was a valid interpretation of what you asked and how to better specify what you want. But that's how it really just shows you the gaps in your own understanding of a problem.

The most rigorous "private property advocates" don't recognize intellectual property as a legitimate form of property in the first place: private property is a natural phenomenon that emerges as a solution to the problem of physical things being inherently exclusive in possession and use, and IP is a creation of positive law meant to artificially apply the methods for solving that problem to another, unrelated question that isn't part of the same problem domain.

Thinking about just the domain of the stock market only: getting a "win" on it means getting a leg up on everyone else participating. Best example I can think of of a pure zero sum intelligence contest. Programming UIs might have a point where you just can't get smarter at it, but in an intelligence contest like a stock market, I don't think there's a ceiling.

Google this: do not delegate understanding

You will find a lot of articles from before LLMs about not delegating understanding of your core system or business. You could say that the software is not your core business so you don't have to understand it. But if the software is any good then it should be taking care of a large part of the business. So software is your business and you shouldn't delegate understanding it.

If your objective was understanding rather than, say, getting a new operating system running, couldn't you use the stronger models to produce artifacts and then ask them (or weaker models) to explain those artifacts to you? Probably the stronger models would be able to produce artifacts that were more worthwhile to study.

Maggie Appleton suggests some ways that AI models could do a better job of communicating about artifacts to people in https://maggieappleton.com/planning-agents, although she's focused on the use case of the person deciding what changes in the artifact to request from the model.

Hmmm, I took it the opposite way, actually.

There are many ambitious things I have tried to work with Opus 4.8 and Opus 5.5 on, and it just can't get there. It always falls back to some tried and true method or some valley that it gets stuck in. In those times, it was impossible to push it forward into more creative and exploratory thinking based upon my relatively advanced pushes and contextualizing. So I took the commenter's position that Fable 5.2 will respond better to that type of pushing. But that type of pushing actually means you know more than those who are happy enough using the lower models. So that seems like the opposite of what you said.

Gareth321 5 hours ago|||
I'm closer to a Product Manager so I'm not sure how useful these examples will be for you.

One important constraint is this topic of intent (also referred to as alignment). Specifically, when a user requests a feature or change, there is MOUNTAINS of implied context and intent in their comment. Some cultural, religious, social, economic, base on work and personal experience, their use cases, their values, what they intend to get done, etc. Every time these models get smarter, they get a little better at understanding this context. It's combination of reasons. Some of it is parametric. Some is inferred. Some is about selecting the right data to examine and research. As these models get smarter, I spend less time time iterating and educating the model. They reach the intent faster and better.

From what I hear and experience, this is also true in the coding space. LLMs are basically another abstraction level on top of formal languages, which sit on top of compilers and machine code and etched instructions. Smaller and dumber models require a lot more hand holding to achieve the same results. They're less capable of inferring the gaps. Less capable of extrapolating potential negative outcomes of the change they're making. Less/less useful parametric knowledge. Less capable of selecting the right data to use to make the right decisions. They do what they're told.

This has been less of an issue for coders who religiously document, understand the codebase and architecture intimately, and demand to be kept in the loop on every change. So seniors often do not see the utility of smarter models. They know exactly what they want, how to ask, the context to provide, and how to assess if the change worked as expected. The utility is for the 99.9999% of the world which is not a senior developer.

While what you say mostly rings true to me, I don't see how it could result in the valleys of stuckness I was asking about.

They are generally things I don't particularly want to share, as I view them as ideas close to my heart. The general pattern was what felt like redirecting from the harder problems and an unwillingness, if we can call it that, to go there. In some sense though, it's hard to understand how these more advanced models get around that, because these models are tuned to the most probable answer. When you come at them with a novel idea, they always seem to water it down in the end.
svnt 11 hours ago|||
I have also found this — once you get out into some really novel workspaces they will revert back to replication of adjacencies that already exist. Fable 5 and 5.1 in particular will talk around the issue in a way that no model prior seemed to.

I think the issue is fairly fundamental, perhaps because of tuning, perhaps even beyond what they are tuned or trained on, because the bulk of what they can go find and ground into seems to drag them heavily toward implicit biases that split around categories I can’t quite discern. The category boundaries sometimes look like academic fields, but sometimes they seem like more fundamental attractors.

Roark66 29 minutes ago|||
As one poster replied above, there is code one doesn't need to understand if what you care about works. A good example is when I first tried a couple of local AI models on my highly unusual inference hardware.

It ran like a dog. Few nights of running Fable (later Opus 5.5) with a 7 strong team of DeepSeek v4.1 Flash 1017 (don't mistake it with 0731 that is crap) and llama was running 10x faster and vllm was running even faster when before it would not work at all.

I've run similarity and needle tests and the results are exactly the same content wise. But 10x faster. I've relied on this for a month now and I'm pretty happy with how it runs.

Do I now need to learn CUDA Kernel programming to understand how it was done? I don't think so. It's for my personal use. Not for a paying client so no warranty is perfectly fine.

But I also use a lot of AI at work in an I dusty where people may die if the code is buggy. So I absolutely verify and understand everything.

There is a middle ground too. Understanding the architecture.

For example I used a bunch of DeepSeek models supervised by Qwen to build adaptive-acl. A pi coding agent plugin that deterministicly checks if every tool used by an ai during an agentic session matches user intent to give permissions for those actions (reading/writing data, network access etc), as a part of this plugin I run an llm, a classifier that runs over user's prompts and extracts these permission grants then saving them in a format deterministic layer can process.

The design includes massive number of assumptions and compromises. For example, if a user allows writing this implies permission to delete and reading if what was written etc.

The thing also includes over 4 thousand actual instances of tool use preceded by "permissions talk" from my live sessions and that whole collection can be run to test for regression etc.

At some point during one night the AI had a regression and decided the best way to resolve it would be to add regex based language processing elements to the deterministic layer (a huge no no, this has to work regardless of the user speak English or Swahili, also regexing natural language is a disaster waiting to happen).

I knew enough about the architecture to notice that and burn it out with a hot iron.

That is the problem with AI. It sometimes solves problems the easiest possible way causing massive issues for later. So if one uses it for important stuff it is good to understand the architecture and the plan of what it is going to build at the very least.

I see this mindset a lot from people who I can only presume have only ever been individual contributors.

Having run teams, as much as I love getting into the details of code I care about, in the 30+ years I've been in this business, I've only ever even seen a tiny proportion of the code my teams rely on.

And the non-technical people in these businesses will have seen none of it.

They all take it on a combination of trust and verification of outcomes that the code does what the developers claim it does.

Increasingly we're getting to a point where the output from these machines are more trustworthy than an increasing proportion of human developers, and more importantly: Increasingly often good enough.

Especially as more and more of the code becomes throwaway.

I have a side-project that is profitable, and that is profitable only because I haven't needed to spend time reading the code. If the code turns out to be unmaintainable? Doesn't matter - it's so cheap code that it is reasonable to just throw it away, and start over based on the lessons learned. It enabled me to take an opportunity to profit I wouldn't have been able to profit from if I had to set aside time I didn't have, so even if it was to totally fail in the future as a result of issues with that code it doesn't matter.

As the cost of good enough code falls towards zero, how we think about which code matters and how much we need to understand it will fundamentally change.

Increasingly, a lot of code is even just part of a conversation with an agent to me. It's throwaway, for the duration of a session. Who cares if it lives on?

I don't trust or need to trust most of the code I build any more. I trust the measurable outputs. The verification pipelines we build. The feedback mechanisms we build. Those I need to read and understand.

That's no difference than when working with a team. The only thing that is different is failure rates. And at this point, for some thing the machine failure rates are still higher, for others it is lower.

> Fable is exceptional at drawing. It’s ability to render an image with JavaScript actually has me questioning the value of dedicated image models

I’ve been shifting away from using more traditional GenAI models in favor of just giving LLMs access to a custom drawing language (LOGO-like) to generate imagery and its been going shockingly well - Opus 5.5 in particular.

I put together a simple LLM driven skill that creates old adventure game (EGA) environments from simple pencil sketches and it works really well. And being procedural, they're much easier to make surgical changes to without degradation.

Yeah it's entirely LLM driven! If you look at the repo, I explain more about how to use it. Basically, you give an agentic coding harness capable of tool usage (Opus 5.5, Qwen 3.8-27b, etc) the skill which explains the drawing system: simple things like how to set the colors, position rectangles, draw polygons, etc. and it uses p5.js to render them.

It has three different modes:

• You can simply describe a picture, and it'll automatically generate an image using procedural code.

https://kq-styles.specr.net/#/scene/custom/elk-valley

• You can ask it to paint over an existing image. That's what those examples show, like me creating EGA-style equivalents of various scenes from the original Myst.

https://kq-styles.specr.net/#/scene/myst/r01-c00

• The last way is to give it a rough pencil sketch. It's the mode I use the most since it's very valuable when building an adventure game to position objects in a room.

So instead for each room that needed to be rendered they just saved a series of vector instructions that would re-render it in real time. On slower machines, you could actually see the rooms pop in piece by piece. I wanted to kind of approximate that same aesthetic because it's just super cool!

Does Fable 5.2 outperform Opus for data science work?

Not just "iterate on this XGBoost model" but actually looking at a problem and designing and carrying out a short-term R&D program including probability modeling, model fitting diagnostics, how to respond to various kinds of results, how to interpret/reason about what it finds, etc. That's really where I saw all the models perform poorly, and where I saw the first big step increase from Opus 5 (pre-5.5) to Fable. But then Opus 5.5 came out and I haven't needed Fable since.

Mind you, I'm doing slightly different work (and I'm very much "in the loop" still) than when I performed that side-by-side test. But it's really amazing what Opus 5.5 can do. I now have a powerful data science AI assistant that not only can write any script I need it to (including some scripts I didn't even realize I needed), and it has an encyclopedic knowledge of everything ever, and it constantly checks me on oversights, it handily derives expressions and clever model reparameterizations that aid, it has great insight into model behavior, and it has an amazing ability come up with ad-hoc experiments and tests that would have taken me 2x as long to even think of (let alone implement by hand).

It's not at the scared-to-lose-my-job phase yet, but it's become a tremendous force multiplier for a smaller data team.

I can describe a vague analysis on the data, and it will handle every step: transformation, preliminary analysis, formulating more precise questions, creating visualizations, running statistical tests, interpreting results, thinking about stakeholders... And in some of those steps, it finds things that I might not have considered.

If it wasn't for grinding all of the hard problems and hands-on projects and various programming tasks I had to do by hand over the years, I wouldn't be able to keep up with the agent, and wouldn't be able to get good results out of it, because I wouldn't know what it was doing and wouldn't be able to steer it appropriately. My schoolwork 15 years ago was more than formative, it remains critically foundational for my job work today.

Based on the other comment it sounds like maybe I need to give Fable another chance, and then I suppose I won't have to steer anything at all. But at the end of the day I am not paid to be a meat proxy, I am paid to deliver things for the business that employs me, and the things I deliver are my responsibility, not Anthropic's.

So I say, embrace AI as a learning tool, let students use it to bypass programming on assignments where the programming is of secondary importance, require oral defense/presentation for projects, make homework worth a much smaller fraction of final grade, and make all of your tests in-class and hand-written.

The reality is that the entire nature of education has to change to account for cheating becoming essentially free and virtually impossible to detect. Grinding through a problem set in the library is still tremendously important, but it's going to be harder to motivate students to do it without just cheating. Some students are conscientious and will do it anyway. Some won't. The hard part is going to be crafting curricula and exams that separate the two kinds of students. Fortunately you share that problem with just about every other professor in the world right now, so at least you shouldn't feel responsible for solving it all yourself.

Relevant anecdote: I used Wolfram Alpha to cheat on my calculus homework in freshman year, and then I got my butt kicked in the exam and a C final grade that never quite averaged its way out of my GPA. That felt horrible and it was a strong motivating force to get my shit together, but that's only because I'm a fucking nerd and I really cared about learning in school and making a career out of what I learned. On the other hand, I really was struggling with the material, which is why I tried cheating in the first place. Maybe if I had today's AI I could just ask it to help me learn better.

Fable made it work correctly in 2 days, it stayed on point, identified the real problems, and gave me clean code that was suitable to merge.

The task was simply to warm the hot path of an app so that latency was not as jittery for some rare, but important, events.

Fable built a reliable repeatable benchmark, disassembled the code to figure out how much could actually fit in L1, made tactical changes to eliminate bloat, and reliably achieved high coverage with minimal edits.

Opus just tried a bunch of random ideas without a plan, hoping to find something that sticks.

> Starting from an empty folder, the model coordinated over 1,000 subagents, working around the clock for eight days writing, testing, and reviewing code. It produced a working operating system that boots on a laptop

This, to me, shows a problem I have with AI: it is reinforcing inequalities. This is literally brute-forcing an OS by throwing money out the window.

It does not sound AT ALL like a clever way to build an OS. But they can do it because they have orders of magnitudes more money to spend on that than people who would actually know how to build an OS.

The thing is, brute-forcing software may be the best solution to make money. So if you are rich and can brute force software in a dumb way, chances are that you can make a business out of it. If you're poor but know what you are doing, you cannot compete.

Technically, it is impressive that they can get a program to do that, but they are wasting money and energy doing it.

Because on that specific benchmark (FrontierCode 2.0), Medium is Carbon's best effort level and xhigh is Fable 5.2's best effort level. You can see that on the graph your next point is about.

And it's just that one benchmark that's at medium. "All scores show each model’s highest-available effort unless otherwise noted".

> - How did they produce such a bizarre effort-intel curve for Carbon that goes against every available benchmark?

The graph is labeled as being about FrontierCode 2.0. Those appear to be Carbon's scores on the official FrontierCode 2.0 leaderboard: https://cognition.com/blog/frontier-code-2.0

> - Why did they leave Carbon-- positioned primarily as a cyber model-- off of the single cyber benchmark comparison?

> - Why do they switch to comparing against Argon (rather than carbon) for robodojo?

Because no numbers are available for Carbon for those benchmarks, and the model isn't publicly available so they couldn't run the benchmarks themselves?

And from your followup:

> Because on that specific benchmark (FrontierCode 2.0), Medium is Carbon's best effort level

I am referring to the chart that cross-compares multiple benchmarks, which Artificial Analysis clearly shows Carbon-high as superior on. Further, AA's FrontierCode chart places Carbon-high as having a higher score on Frontier 2.0 than Carbon-med (https://artificialanalysis.ai/evaluations/frontiercode-2-0?m...)

Where it gets very interesting is when you look at the Cognition "FrontierCode" publish date (2026.10.27), and the revision as of 10.28 in web archive (https://web.archive.org/web/20261028175237/https://cognition...). This revision has a VERY different Carbon effort / intelligence curve where high beats medium.

It is only with the latest revision, as of today, that all of a sudden Carbon's benchmark curve goes cone-shaped. Curious, indeed....

I agree with GP: without a comparison to Opus 5.5 or some other models, it's not clear how much of an advance this is. If anything, my experience is that performance optimization in existing codebases is something existing models are already great at: it's measurable (you directly profile or try experiments to see what works) and the code architecture is usually relatively fixed (at least relative to deep/greenfield work where there are large architectural questions to be addressed). Newer models might be better at generating ideas for things to try, but if you're getting 36x then it honestly sounds like you have a lot of low-hanging fruit.

> Our first formalization of Fermat’s Last Theorem, performed by an unreleased research version of Claude, took 11 days. It relied on a purpose-built harness along with guidance from a human researcher. By contrast, a team of 1,000 Fable 5.2 agents fully formalized the theorem in just 30 hours, with minimal human intervention. Fable 5.2 started from minimal prompts, built its own ways to coordinate, and used no mathematical references, only a list of intermediate theorem statements to score progress. It needed one-third of the action tokens as our first formalization and produced a proof seven times shorter. As can be seen in the figure below, Opus 5.5 (with the same 1,000-agent setup) completed only 26% of the formalization in 18 hours, and barely made any more progress after 30.

Most people don't really have intuitions on what it means to push the frontier now (because AI has surpassed everything they are good at, for example, coding). We are truly inside the singularity (using Kurzweil's definition, slightly paraphrased - the time when technology progresses so fast no one can keep track with it).

legulere 18 hours ago||
Kurzweil's definition contains exponential growth across technology, something that we are not seeing.

What we're seeing instead is maybe akin to the green revolution. Before nitrogen fixation nitrogen was a resource constraining us humans. Lack of grit is what kept us from solving mathematical problems. However this lets us run into other resource constraints. A lot of technological progress does not solely hinge on thinking/processing. The speedup of creating new medicines with LLMs will probably be very small, as you still need to do all the testing. In software development you still need to first find out what to build in the first place and even mathematics where LLMs seem to shin brightest, it's becoming clearer that mathematics is not just solving mathematical problems.

Apart from that, a good coder is better than LLMs, shown by the amount of hand-holding needed. The only issue is that the amount of research an LLM can do and knowledge it is trained with far surpasses the amount of work humans would need to spend by hand, but we can also us LLMs for that.

This is not quite the framing he uses, but we're quibbling about subjective terms. In his 2005 book, The Singularity Is Near, he defines the singularity as a future period when technological change becomes so rapid and consequential that human life is irreversibly transformed. I would argue this is what we are seeing today. Just because we don't yet have replicators doesn't mean the definition isn't met. It really comes down to how you personally define words like "rapid" and "consequential."

I would imagine Anthropic is hitting a wall on the number of simultaneous agents that can be useful on a task and are working on increasing that maximum. I would assume if they could get twice as much progress by using 10000 simultaneous running fable instances instead their brief would state that.

IMO, it is very interesting and also very alarming. At some point the barrier to the exponential progress is the amount of computation available. I would consider hitting this limit and then likely using the same said swarm to help resolve it via various means as very much fitting under the definition of Ray Kurzweil's singularity.

Also, I would disagree, Fable is a sufficient coder. The average human being better, even if that is true now (and personally I wouldn't agree), the average human is limited in the number of 'human instances' he or she can interface with at one time.

if 1000 fable instances is better than any human at a task, how about 1 million instances running? Much easier than finding and hiring and coordinating 1000 extremely productive and intelligent human beings. Much cheaper too, it appears.

But in reality λ is usually between 0 and 1 — allowing more people to help, but with diminishing returns. For example, if λ = 0.5 then 100 people working together get as much done as 1 person working for 100^0.5 = 10 times as long"

There are diminishing returns to more agents, but they're faster and can scale further than a single smarter agent - it's not really possible to just give 10k times more thinking budget to a single agent because it runs out of context, so for problems that require that much context you can ask the agents to specialize. Each only has a small view of the problem and they probably duplicate a lot of work and step on each others toes and make arcane bureaucracy but there is literally no other way to scale beyond a certain point

How do you define "good coder"? I've yet to see LLMs that write better than what I consider the best human code. I think Michael Hashimoto showed that not too far back where getting LLMs to optimize for a problem resulted in code better than naive but much worse than expert and that's before even talking about how that code looks/reads.

I'll admit I'm not on the very cutting edge models but LLMs make weird tradeoffs and lack creativity. They will sometimes write marginally better but way over-complicated code for no good reason. That can have performance implications and they're generally not "aware". They can gain awareness via profiling but again run into limited creativity or big picture understanding. They are good with cliche but not as good with novel situations. With human guidance this is still productive/useful but as the systems grow more complex they are less able to reason correctly about them.

I would say that in certain situations they outperform the average software developer. They definitely outperform in speed and output. So they're like a maybe 1600 ELO chess player for software. I.e. they play chess better than all non-chess players. They play chess better than many chess players. But they're not "master" or "gm" level across the entire discipline.

Math is for sure about solving mathematical problems, mathematicians complaing about humans capability of understanding it. If you need math an LLM understands, it might not be relevant if you understand it if an LLM is getting a lot better in adjusting itself if it goes the wrong way.

And this situation is only a few weeks old. We don't know how this field continues to progress. Books like the culture series and other scifi do describe a future were humans spend their time only to understand what the machines are doing or did.

The speedup of medicines is for sure faster with. There are still old labs doing everything by hand and the neolabs doing everything a lot more automated. An AI can do experiments 24/7 and can scale with the hardwarelabs, but it also can hold the whole research field in context and it might be a lot faster of choosing the better experiments or the right ones to begin with.

In software developmet (my field) i can do today alone what you needed a Team for. Yeah it doesn't help the field of software engineering if you need 5 times less people and you don't have any motivation AT ALL to teach someone avg. We are already planning to remove one member of our team due to AI. And we will not extend the contract of 2 consultants.

It just doesn't make sense anymore. If i explain in a ticket a task well enough for someone who has not been in our team for years, the AI is already better in it. We don't struggle with AI output, we struggle more with not having a Monorepo.

Give an LLM access to a GPU system or a GPU cluster. It immediadly feels complelty different then running it on some laptop. It can now do simulations, a lot more and faster experiments etc. I had this epiphany just a few month ago. I always used my laptop for projects (it needs very little ram, i can quickly check what it is doing and i actually do use it primarily when im on holidays) until I thought "let me use claude to do some gaussian splatting experiment its always so cumbersome to use these tools" and it changed my perception immediadly.

AI is actually still really bad at architecture. It produces very good localized code, like an auto complete. It produces so much of it, that it can be overwhelming, but it's not remotely better than the equivalent aka an infinite number of talented humans doing the work.

The scale of it (aka 'make me a video game') is daunting and I think misinforming our intuition as to what is going on.

LLMs are brute forcing outputs and attacking math problems is not a singularity, it's just more compute.

What we are witnessing is the ability for machines to use fuzzy concepts, instead of very strict code, which allows it to map into a much greater variety of things, aka code, pdfs, web - and crunch/compute the content.

No human ever wrote a module and 'voila' - it's a constant process of iteration and refactoring - observing the situation, identifying paths to reduce complexity or state, grouping behaviours etc. etc. The best AI doesn't do this very well at all. It can do a tone of planning but it tends to very much be 'one waterfall iteration' and it's suggested improvements after that are generally poor.

It just does not work, we have to direct the iterations.

"Achieving AGI" strikes me as a mostly meaningless phrase. I'm skeptical that it is a boolean event. They're already smarter in some ways, their impact is large and gradually rising, the set of specific tasks that they aren't capable of is gradually shrinking. If AGI means anything useful, it seems like we'll only see it in hindsight and have to argue over when "it" happened.

Likewise the singularity. While recursive self-improvement is theoretically trivial (just tweak a random subset of weights like a monkey with a typewriter, eventually you'll get something smarter), the resulting exponential improvement is still very hypothetical and feels unlikely. Unless you're ok with an exponent of 1.000000000000000001.

The ownership class, the capital class - whatever people prefer to call it, will still call all the shots as they always have, and always will.

So whether that's a CEO at the top instructing a human manager that then instructs AI systems, which then put into motion plans that include the harnessed humans getting prompted, or however it's decided to best configure the top operational tiers - that's all fairly irrelevant ultimately. All human labor, and all AI labor, will be in harnesses. Realistically all human labor has always been in a harness.

The people in charge will be the people that control the capital. They will instruct the AI to their bidding, they will control the data centers the AI lives in, they will own the robots doing the labor in factories, they will own the factories, they will control the grid, they will control the electricity generation, et al.

It's true now, it'll be true tomorrow. Nothing fundamental will shift at that tier: don't be labor, own.

If you're a software developer, you're increasingly depreciating labor. Every unit of improvement the AI systems see, the average human software developer's labor value diminishes. It's diminishing extraordinarily fast, kind of like a confrontation between increasingly productive machines and physical human labor during the industrial revolution.

IMO, it is very interesting and also very alarming. At some point the barrier to the exponential progress is the amount of computation available. The average human is limited in the number of 'human instances' he or she can interface with at one time.

if 1000 fable instances is better than any human at a task, how about 1 million instances running? Much easier than finding and hiring and coordinating 1000 extremely productive and intelligent human beings. Much cheaper too, it appears.

The age of AI + robotics will just make it that much harder to climb for most people, these are systems that are in aggressive, direct competition with human labor. And in short order the AI + robots will be vastly superior to human labor (it doesn't really matter if we're speaking in terms of 10 years or 30 years).

AI will consolidate the winnings. The gigantic gains by the elite rich related to AI over the past few years, is merely a hint of what's to come. Capital will win as it always does.

There will be some gains for most everybody else, those gains will be comparatively trivial though. A house bot that saves people an hour of labor here and there, AI that automates some trivial life tasks.

Fewer humans will be needed per dollar of output. Those gains will not go to labor, they will go to capital, the capital that owns the data centers, the factories, the stores, et al.

In the physical space (AI + robotics) it'll be a chaotic, slow'ish moving change, slower than the hypsters are predicting now, but it will happen regardless.

That barista job largely won't exist in the future. China will replace them with $3,000 bots with high-functioning AI software, and they definitely won't be powered by expensive Nvidia GPUs.

Slow changing service & manufacturing spaces will see a high wipe out ratio in terms of human labor being eliminated.

Walmart has 2.1 million employees, most are doing repetitive tasks that require modest levels of intelligence. If they could eliminate one million of those with AI + robotics, for a cost of less than ~$15,000 per year, they'd do it immediately. It's hard to imagine a future where that isn't going to happen. That human labor pool is costing Walmart probably $80-$100 billion per year. Amazon is even more forthright in their desperation to remove the humans from retail.

I haven't found anyway to make an LLM produce exceptional code at all. It is all far far too verbose and the models explain that this is necessary so that they can read and understand the code to modify it as it's being built.

But I can write much cleaner code that is easily human readable and the models can read it and modify it just fine.

So I'm not really sure what the issue is as to why they can't create high quality simple code. In some industries where there is major money on the line with every implementation the current state of LLM produced code is fully unacceptable.

Why re-formalise Fermat's Last Theorem instead of doing something new? It's obviously an improvement, but it's an odd thing to boast about as opposed to a novel formalisation or proof.
stalfie 18 hours ago|||
It's how RLVR works, when you have a task with a verified answer, you rerun the model on it and promote the reasoning chains that reach the answer. That way you can hill climb model capabilities on any problem you find, which generalises to new problems to solve, which you can then hill climb again and so on.

So since they are doing that task anyway (re-solving the problem increasingly more efficiently), this is a easy check point to publish to show how far they've gotten in that process.

The older, original definitions of "singularity" were less about "herp derp superintelligent AI blah blah".

> The older, original definitions of "singularity" were less about "herp derp superintelligent AI blah blah".

No they were exactly about superintelligent AI!

Vinge's 1993 article literally opens with this!

> What is the Singularity? The acceleration of technological progress has been the central feature of this century. We are on the edge of change comparable to the rise of human life on Earth. The precise cause of this change is the imminent creation by technology of entities with greater-than-human intelligence.

It's one of the options, but not "oh superintelligent AI comes in and we mostly know what that means so we want to speedrun it " - which I'll admit I was not very clear on.

In fact, one of the options Vinge considered was a "group intellect" formed from how humans communicate more thanks to internet

dwohnitmok 15 hours ago||
What Vinge is talking about is way closer to the weirdness of AI than the mundaneness of e.g. a societal grouping of ordinary humans.

Even for that option, Vinge's comments in the conclusion of the article make it clear he's thinking primarily of very weird superintelligence and the group intellect is some sort of physical mind meld/hivemind that essentially just is a biological substrate for AI.

> The post-Singularity world will involve extremely high-bandwidth networking. A central feature of strongly superhuman entities will likely be their ability to communicate at variable bandwidths, including ones far higher than speech or written messages. What happens when pieces of ego can be copied and merged, when self-awareness can grow or shrink to fit the nature of the problems under consideration? These are essential features of strong superhumanity and the Singularity. Thinking about them, one begins to feel how essentially strange and different the Posthuman era will be -- no matter how cleverly and benignly it is brought to be.

From the very beginning with Vinge, the Singularity has been primarily about the craziness of super intelligence rather than a more mundane technological explosion.

throw310822 18 hours ago|||
Thanks for your link, this (a few paragraphs from the top) seems to settle it:

  Stan Ulam paraphrased John von Neumann as saying:

  One conversation centered on the ever-accelerating progress of technology and changes in the mode of human life, which gives the appearance of approaching some essential singularity in the history of the race beyond which human affairs, as we know them, could not continue.

   Von Neumann even uses the term singularity, though it appears he is thinking of normal progress, not the creation of superhuman intellect.
So the concept of technological singularly precedes and is independent of that of intelligence explosion- although one could argue that the latter is the most logical way for the singularity to come about.
dwohnitmok 15 hours ago||
You're cutting off the sentence that comes right after:

> For me, the superhumanity is the essence of the Singularity. Without that we would get a glut of technical riches, never properly absorbed.

Vinge's definition is what popularized the singularity (rather than simply a singularity at some point).

It's incredible. Automating the scientific process and knowledge. It's crazy to think what the world might look like. Both in terms of putting the knowledge into practice and how we think of scientific discovery.

I mean we don't even think about it but currently we are sort of discovery starved. We are fairly able to keep up with the theory. If a new technology is discovered we can implement it before something better comes out. What happens when our N discoveries per days becomes 1000N discoveries per day?

It flips. We now have more knowledge than we know how to capitalize on. We have to search it. Mine it for opportunities.

And then we automate that.

At least to me the video showcasing the capabilities of the model wouldn't fit that definition.

It doesn't have a human mind and especially a human feel behind it, simple as. It's like the famous example with what pornography is in the eyes of that judge, i.e. "You know it [the fake-ness, that is], when you see it", once you start looking for reasons for why it isn't fake you've already lost the battle.

The problem is that making us believe that fake isn't really fake is put in the balance with literally trillions of dollars asking us to believe just that (i.e. that fake isn't really fake), so I agree that for the time being stating the obvious is still an uphill battle.

> The AI had built a bureaucracy.

> The agents decided that my request to “polish” existing worlds meant each new version had to beat the old one in a blind vote by a group of judge agents on twelve test screenshots. So the teams making the new versions started optimizing the worlds for those particular screenshots. After noticing this, the lead agent banned the trick and created tighter rules for assessing new versions. By the next morning there was a rule book (I never asked for one) with 84 sections. Rules were added as the AI encountered issues, and no text was ever cut. After twelve days, it had 204 sections and 87,500 words. Soon, launching a new world required an approved idea, three AI judges and a full code review against the rule book.
