What I find fascinating that there is so little substance in this article about the quality of produced code and the medium. Is the code documented and tested? Is it understandable and extendable? Is it secure? What language, framework, database was used? Author mentions judgement and taste - well, is the code tasteful? Will the model rearchitecture the entire thing if I ask it to add new functionality, spending another 9.5h in tokens? I assume that the research part is domain knowledge = how different types of travel translate to time making it presentable; how did the author verify this?

These questions are even not about AI: if I were to give money to a human agency and were given something they tell me works, I would ask the same questions. If I did not know how to evaluate, I would hire people that do. With LLMs the verification part is what bothers me the most.

These posts are never written by software engineers, it’s always some tech exec, retired engineer, or VC. This author is apparently a professor at the Wharton School of Management? None of these people have to ship or maintain real products, they’re just making side projects.

The only decent software engineering perspective I’ve seen has been from Mitchell Hashimoto.

jimbokun•about 2 hours ago

Well that’s kind of the point.

They can just summon bespoke software out of the ether that only handles the use cases of themselves and a few of their collaborators.

Making “side projects” was mot possible for non-developers before powerful LLMs. Now it is.

an0malous•about 1 hour ago

I don’t think that’s true, I think these authors are making a much stronger claim that AI is proficient or even an expert at software engineering. This author describes how complex and sophisticated their software is, and the only value he’ll concede to “coders” is that there might be a few bugs they’d need to fix.

Imagine not being an architect and using Claude to put together a building plan, then concluding it’s basically done but we might need a real architect to double check the measurements. It may even be true but I’d be skeptical if it’s always non-architects saying this.

shimman•about 1 hour ago

Making side projects isn't a trillion dollar industry tho, adding to the fact that we are facing another global supply chain crisis due to the Iran War; the US is about to commit the biggest self-own ever in the history of empire.

cgearhart•about 3 hours ago

I’m starting to realize that LLMs are really good at building low-stakes projects. Your questions mostly presume that the stakes are higher. The software will last a long time; the requirements will evolve; we can’t tolerate mistakes; etc.

The trick to getting good at using LLMs for software is to learn how to make _all_ projects low-stakes.

qaq•about 3 hours ago

You don't need LLM for that. You make _all_ projects low-stakes by working on green field project using (insert buzzword soup of the day) and leaving for a new green field opportunity (that requires experience with buzzword soup of the day) before the project ships.

rpdillon•about 1 hour ago

This is really insightful, but I think it also extends to making the project either low stakes or low complexity. I have this lurking feeling that the preferable architecture for software will change as a result of LLMs because they're good at working on low complexity modular components more than they are on high complexity million-line code bases.

acedTrex•about 3 hours ago

this doesn't really work in the real world. There are many things that actually matter, engineering is fundamentally about handling them.

I clicked one of his examples intrigued "a snake game where the snake is self-aware and crazy things happen;". Played for 1-2 minutes, and it's the classic 1980s snake game. Am I missing something? What is "self-aware" about it? Some funny messages at the bottom of the screen? And what are the "crazy things"?

starshadowx2•about 1 hour ago

It sounds like you either didn't play enough or you are missing the new mechanics that get added over time. There's definitely more to it than just regular snake.

vunderba•about 2 hours ago

I had the exact same thought. To me, it feels like they just took the fairly common “sentient video game character” trope and bolted it onto a very conventional snake game.

I will say, the act of eating creates a "bulge distortion" that flows down the length of the snake is a nice touch though.

You probably don't care about the ingredients or engineering of asphalt, only if the road does its job well or is filled with potholes. Outside of the software industry, nobody gives a shit about code or databases.

eithed•35 minutes ago

I agree. But if I'm paying for the road (even as a taxpayer) I get angry that after a year it's full of potholes and that there are unnecessary signs warning about penguin crossing, making it cost 2 times more than it should have (and dont get me started why this road is really a highway leading to my house). I'd want certain qualities. And this article is basically = you will get a road, built quickly

But yes, you are right - I don't build roads and don't know what is a price to build a road and how to determine the quality of correctly built one, nor I will ever care or learn.

eithed•about 1 hour ago

True, but you should say that about every thing. Does it matter to you how the car drives, as long as it takes you to your destination? Well, yes, it matters: how will it deal with a crash, and if it's possible to replace a part and if anybody can just open it if you leave it outside. I will be amazed if somebody shows me their home-printed car, but if they'll try to sell it to me like a new one...

adamtaylor_13•about 3 hours ago

I'm becoming more convinced these are questions of the Before Times. Yes, yes—heresy, I know.

Yet, I can't deny the reality that I observe working with LLMs every day. If this truly is a step-function (as some are sgguesting), then I have absolutely zero concern for the quality of the code.

JumpCrisscross•about 4 hours ago

Anecdote: I fed Fable some models I’ve been hand verifying (basically, I sketch out a scenario for Opus to model, it builds it, I ask it to show me the math, I correct it, we iterate like this, then I double check its code to make sure the math matches the model logic). Fable found almost every error I found, and then had some interesting suggestions for additional variables.

It also burned through my usage quota like a late-90s Hummer.

matheusmoreira•about 2 hours ago

> It also burned through my usage quota like a late-90s Hummer.

Yeah. I have a Max 5x subscription and Fable burned through 16% of my weekly quota in a 40 minute code review session. It didn't even finish the review, it switched back to Opus 4.8 in the critical memory safety parts where I actually needed Fable.

I feel like I'm going to get priced out of these models soon. I should probably try to get the most out of Fable until June 22nd.

cyanydeez•about 4 hours ago

now for the best question: whats your ROI here?

Ferret7446•about 3 hours ago

Humans are very expensive, so the equation almost always falls against them.

It's not just salary, but also safety/labor regulation, legal risk, vacations, sick time, personal conflicts, HR, benefits.

Even when automation is more expensive on paper, it's generally still cheaper

rstuart4133•13 minutes ago

> Humans are very expensive, so the equation almost always falls against them.

You underestimate what these models cost. Uber's budget is $1,500/dev/month. I gather that was put in place because the dev's were going through $6,000/dev/month, which Uber decided could not be cost justified.

Fable costs at least twice as much, or $12,000/dev/month.

Fable can apparently work for hours without supervision, which means a skilled engineer can now have it working on many tasks concurrently. I would not be at all surprised if they can put a nought or two on that number. If you do that, you are well out of "what a human costs" territory.

gopher_space•33 minutes ago

One of the large (and enjoyable IMHO) challenges in this line of work is developing a de facto understanding of your process and the context it's in service to, and that's only possible if you're actually on your industry equivalent of a "shop floor" for each domain the project touches.

As far as I can tell this part of the job isn't really on anyone's radar anymore.

TheOtherHobbes•about 1 hour ago

Good to know that LLMs will be removing all regulatory and legal risks, as well as creating a consumer economy that no longer employs or pays consumers.

I can't help thinking there might be some kind of strategic issue here.

Perhaps someone should ask Mythos about it.

warkdarrior•about 3 hours ago

That's the beauty of these AI advancements. You, a human, will have to compete against a model for the same job.

If you get $100,000 per year as a SWE, and Anthropic offers a coding model for $100,000 per year (but working 24/7), then you'll have to give up all of those addons that make the fully burdened cost of the employee. Say goodbye to vacation, sick time, benefits, etc.

Qhemlomo•about 3 hours ago

It just got released, it shouldn't matter.

We know this model will be cheaper and faster with time.

And we have not even reached the timespan/timeframe were we have ASIC style models.

OpenAI has to do something which will beat Fable otherwise Anthropic won. China currently overtakes cars, pv, batteries and very soon silicon chip making, it has all the incentive to also take over AI.

Reading the first few paragraphs of what he calls "the most sophisticated academic social science paper I have yet seen from an AI" does not impress as much as I hoped.

"Posterior beliefs about market demand are purely referencedependent: holding dollars raised constant, they track only performance relative to the founder’s self-chosen goal—jumping half a standard deviation at the threshold, responding steeply for the first ten points past it, and flattening thereafter"

Humans generally don't verbalize data this way. The summary document is also very fluffy.

marcosdumay•2 minutes ago

> Humans generally don't verbalize data this way.

Academic social scientists on the other hand...

IMO, I don't see anything on that line that looks like an AI. LLMs also have a tendency to bring words from one context into another, but this is also the context I would expect to see those words.

olafmol•about 3 hours ago

This little line from the article scares me: "but a software engineer would iron out the remaining potential bugs that I could not find quickly"

Every sw dev knows this is a very dangerous, and unrealistic, assumption.

mohsen1•about 4 hours ago

I have been using it for less than an hour so take this with a grain of salt of being excited for the new tech.

In a project like mine (https://github.com/tsz-org/tsz) I am constantly frustrated that models were not doing enough research and were not taking into account other situations. Again and again models would produce code that would fix one thing and break 2 other tests that were "unrelated".

With Fable it seems like tasks are taking much longer (I have not seen a pull request from Fable sessions yet) but reading the transcription of those sessions I can see how it is doing the right thing by not leaving any stone unturned.

As the article says, it's hard to communicate this "feeling" about models because it is very project specific but I thought I share

anematode•about 3 hours ago

Does this not indicate that the project might not be structured in an appropriate way that allows incrementally adding features?

layer8•about 3 hours ago

In general, sooner or later you need to restructure one thing or another when requirements are changing. Good code lets you reason about a refactoring, and experience tells you when it is necessary or appropriate. Coding agents aren’t very good at the latter.

mohsen1•about 3 hours ago

the setup is solid. there are thousands of tests and CI won't let things to merge if tests are failing.

But overall, this is pretty normal for compilers to have this sort of "unexpected" tests failing due to some work in an area. It happened to me when I was coding everything manually back in the day too

anematode•about 1 hour ago

> there are thousands of tests and CI won't let things to merge if tests are failing.

That's not what a clean setup means... I mean good separation of concerns, established invariants, etc.

selfawareMammal•about 4 hours ago

What are people working on that they see such a substantial difference between Mythos and Opus? I'd say I'm working with advanced stuff and more than often Deepseek is even more than enough. Why is everybody a genius in here?

jenniferhooley•about 3 hours ago

Just depends what you are working on. If you are trying to make a video game that's at a level of a decent indie game (think Hades/Baazar/etc), making UI elements/VFX/complex shaders/etc that are organic/interactive/animated that don't feel like a little dogshit vibeslop web-game, then none of the models are even close to good enough to get it done easily. Huge percentage of problems in top 3% games is really hard for any of the models to do with simple prompting.

Personally I don't really care, because I like coding and learning myself and DeepSeek Flash is all I really care about. But it's really easy to have a ton of benchmarks where the top models can't get anywhere close - and I like to test them on these problems to see how good they are getting.

Fable 5 is def a little better than 4.8 btw.

jstummbillig•about 2 hours ago

I am sure you would not find it hard to exhaust any model, if you kept upping your ask enough times.

On the margins, suppose the prompt is literally: "Build a feature complete, high polish Facebook clone". Facebook is complex but likely not super complicated tech, and still I would assume that (after having burned through a substantial amount of tokens) you would find substantial enough differences in the outcomes between different models on that prompt on various fronts.

The above ask is obviously not useful, but what's preventing you from taking on bigger chunks until you approach the limit? At some point you would hit a boundary, where the diff will be obvious.

ianm218•about 4 hours ago

I’ve been working on implementing some common web infra type projects in Rust lately. Basically trying to use a lot of the great primatives in Rust like rustls (modern openSSL) and Tokio (async) to build memory safe or close, nginx drop in replacements.

A small portion of this effort is having a high quality Lua in Rust repo. I’m using mythos to fix some of the performance issues with my Lua interpreter that gpt 5.5/ opus 4.8 had stone walled on.

Not sure if Mythos will be able to crack this but it has been running for a couple hours now with some promising results.

mplanchard•about 1 hour ago

What’s wrong with mlua?

ianm218•19 minutes ago

Mlua works for many use cases but is a wrapper around the C code, so you need to bundle C as part of the build. So this is worse for cross compilation and makes it so you can't easily use mlua projects in wasm32-unkown-unknown. An example is that it would be hard to run a game in the browser that exposes Lua scripting with mlua.

The other reason is that because mlua is just a wrapper around the C code, it has unsafe you can't really get around. So for example Lua is used in Redis, which has this critical CVE https://github.com/redis/redis/security/advisories/GHSA-4789... that a memory safe version of Lua wouldn't have to deal with.

Mlua is still fine or even better for many other cases though!

Our_Benefactors•about 2 hours ago

Myth. Total myth! I recently had to beg for more RAM after continually hitting swap space which causes tools like dictation to stop working, failure to load certain websites without rebooting, and so on. Devs do in fact need powerful machines and the ~$500-1000 an employer saves upfront in machine costs is dwarfed by productivity losses.

Giving your engineering employees new machines in a 2-year cycle that are between the middle and high end is one of the cheapest ROI decisions that a tech org can make.

> It worked for nine and a half hours.

> Again, it wasn’t perfect. As an expert, I was able to spot some errors and omissions (some as a result of the design I had asked for) that I had the AI correct

That's the bit that stuck out to me - that's longer than I would expect to work on a problem in a day or even expect to go back & fix the output of something that has a core reward loop of hours.

My customers are currently clamoring to push down my agent response times from 85 seconds down to below the 20s mark.

At the same time, it is very dissonant to see the industry heading towards hour+ long workflows with an agent.

matneyx•about 5 hours ago

In Claude's defense (and I cannot believe I'm defending it), I know no single dev who could create what it did (Concord), from a 19-page design document, in 9.5 working hours.

We're gonna go back to the days where our bosses ask why we're just sitting around, but instead of saying "compiling," we'll just say, "waiting for Claude."

torginus•about 1 hour ago

I tried to read the 'design doc' - its slop full of vague platitudes and impressive sounding but impossible to pin down management speak - in short, it's slop, and I still don't really get what its supposed to do exactly.

It's some prompt engineered AI harness, that guides the AI to create stats after it researches a subject and ingests the data, but I'm not sure what is it that the tool actually does on top of this.

giancarlostoro•about 4 hours ago

This. I get told things like "you can't build all that on your own?" I've had Claude poop out full feature web apps in under 30 minutes, to a spec. Was it perfect? No, but sometimes even in a simple setup phase you can burn 15 minutes to some obscure setup step that's failing. I cannot just code nonstop at 900WPM or whatever ridiculous speed, and poop out an entire full feature web app, with maybe a few bugs here or there. If you can, come show me, I'll gladly have you race against my Claude prompting capabilities.

Will Claude's code be perfect in one shot? Probably not, will it get you 80 to 90% of the way there with your chosen design patterns in under a few hours? Absolutely.

hedgehog•about 5 hours ago

Work duration is also not that valuable of a measure, you're usually better off defining the process yourself in code and having that delegate chunks of work to the models. The only real issue there is that it's harder to take advantage of the providers' subscription discounts, but on the other hand it's easier to do your own model routing, and there's no way I've seen for the normal chatbots to maintain coherence on streams of work measured in days and weeks.

cyanydeez•about 4 hours ago

I think we hit the sigmoid back when the QWEN models were released. By properly structuring my project, I can point it at any extension I want and get it going for 30 minutes to extend whatever.

We were saying our goodbyes and my buddies dad said to my dad "We'll get there a lot faster, I found a shortcut!" My dad, confused says "shortcut? there is no shortcut, just highway 1..." and his dad insists he found an alternative route, much shorter by kms and we'll fly up there 6 hours faster! Get into the truck and he pulls out 5 pages of printed mapquest... I assure you, having done it, Sault Ste.

I also see some logic flaws. It overlooks the option of going to a major hub to access faster aircraft, rather than hopping on local hubs.

Also, immigration and customs are cleared at the first airport you arrive at in the country, not at the last one.

In some countries, you need to clear immigration even while going to a third country, so 1 hour is not enough to do it.

Would love to see samples of the kinds of prompts you use with both. I sometimes wonder if the specific wording is the secret sauce, I have very few issues with Opus / Claude, but when I try premier GPT models, I get weird output from what I've grown to expect with Claude.

I'm using Fable this afternoon and it's definitely a step up from Opus 4.8, finding and fixing things Opus 4.8 was blind to even perceiving. The next 13 days are going to be fun IMO. And Opus 4.8 was less annoying than Opus 4.7 FWIW.

Edit: A couple hours in and I just got my first gaslighting attempt from the model. Good times!

I just can't stand this type of fawning language.

Was the condition of being granted early access to this castrated model writing a post praising it?

> First, how good is Fable? In experiment after experiment I conducted, it outperformed basically every other public model I have used by a considerable margin.

What makes me excited is that GPT 5.6 (its actually GPT 6) is going to be crazy

Fable is Mythos with extra guardrails, so the analysis holds.

The mythos of Mythos is marketing.

Reading it, I can't help but feel he's being paid to write this. Or maybe he hopes to be paid. The language he uses makes him sound like he's fawning over the lost days of his childhood. Pardon me for being skeptical, but a trillion dollar company running a net-loss is hoping to IPO, and needs to sway public opinion by any means necessary. I would imagine that no dirty marketing scheme is off of the table, even from the self-proclaimed "good guys".

It is not a sponsored article and he writes one of these every time a new model releases. Why would a professor at Wharton need to write sponsored Substack articles.
