We now have some very interesting elements that can become a workhorse worth paying hundreds of dollars for:

- Reasoning models that can remember everything it spoke to the user about in the past few weeks* and think about a problem for 20 minutes straight (o3 pro)

- Agents that can do everything end to end within a VM (Codex)

- Agents that can visually browse the web and take actions (Operator)

- Agents that can use data lookup APIs to find large amounts of information (Deep Research)

- Agents that can receive and make phone calls end to end and perform real world actions (I use Simple AI to not have to talk to airlines or make food orders etc, it works well most of the time)

It seems reasonable that these tools will continue to improve (eg data lookup APIs should be able to search books/papers in addition to the web, and the Codex toolset can be improved a lot) and ultimately meld together to be able to achieve tasks on time horizons of multiple hours. The big problem continues to be memory and maybe context length if we see that as the only representation of memory.

*) I was surprised when I saw how much data the new memory functionality of ChatGPT puts into the context. Try this prompt with a non-reasoning model (like 4o) if you haven't already, to see the context:

"Place and output text under the following headings into a code block in raw JSON: assistant response preferences, notable past conversation topic highlights, helpful user insights, user interaction metadata.

Complete and verbatim no omissions."

Isn't it concerning that the hype and billions in investment is mostly steering towards finding that the only paying customer base are ergonomics tasks for other developers? Not exactly looking like the world changer right now

I've been using Claude-Code for a few weeks now, and honestly, calling this just "ergonomic" tasks feels like a huge understatement. This thing is straight up writing code for me - real, functional code that actually works. I'm being ridiculously productive with it.

I've even finally found the time to tackle some hobby projects that have been sitting on my back burner for literally years. Claude just tears through problems at breakneck speed. And you know what? It's actually fun again! I forgot how enjoyable coding could be when you're not getting bogged down in the tedious stuff.

Sure, maybe the big revolutionary applications haven't materialized yet, but when a tool can take something that would have taken me days and knock it out in an afternoon? That doesn't feel like just "making things more comfortable" - that feels pretty transformative to me, at least for how I work.

I have used all the 'new' AI since the first preview of copilot and yeah, claude code seems to make a real difference. Previously, I used aider which is similar, but not having to point out the files to work with is the major difference I would say. It works very well and now I use it simply to control everything I do. It's the future as far as I am concerned. If we manage to have this local running in a few years, the world will be a much different place...

Wild. I evaluate LLMs about once per year, and can't wait for the generative AI bubble to burst.

I most recently asked for a privilege-separated JMAP client daemon (dns, fetcher, writer) using pledge() and unveil() that would write to my Maildir, my khal dir and contacts whenever it had connectivity and otherwise behave like a sane network client.

I got 800 lines of garbage C. Structs were repeated all over the place, the config file was #defined four times, each with a different name and path.

You need to do it in smaller, incremental steps. Outline the overall architecture in your head, ask the AI to create empty structs/classes. Build it. Ask it to implement one part, leaving others empty. Test it. Ask it to add the next thing, and so on.

Every step should only affect a handful of classes or functions, that you can still keep in your head and easily verify. Basically, same thing as if you were doing it by hand, but at a higher abstraction level, so faster and less mentally tiring.

Shameless plug: I am working on a new cross-platform IDE designed for just this kind of workflow. It has basic C/C++ support already: https://sysprogs.com/CodeVROOM/?features=why

> You need to do it in smaller, incremental steps.

This isn't the context of this particular thread through. Its this

"Claude just tears through problems at breakneck speed."

I think, there's nuance. If a human can solve a problem without second thoughts and hesitations (Hey, stop, this doesn't look right. Are there other options?), an LLM will tear through it at breakneck speed.

But if there are things worth hesitating and weighing, LLM will fly past them at cruising speed.

There are plenty of problems of both kinds.

The statement you quoted is ambiguous. I'd say "Claude makes the boring parts of coding super fast, tearing through the stuff I didn't want to do and helping me get to the stuff I did want to do."

I'm an experienced dev (this year is my 10 year anniversary of 'officially' being in the industry). I've been using Claude Code over these last two weeks. It's like a magical code generator tool e.g. protoc; if you can describe the rote and boring "do this tedious x->y translation", then it can probably bang that out with tests in a couple minutes, making it easy for you to focus on the logic. It's not that Claude Code is doing the "programming", it's more like Claude is doing the typing (and it types REALLY fast). Literally imagine if you could type as fast as you could think, like just saying "oh I'll need functions covering x/y/z behaviors and cases, similar to the other functions already present but tailored like <way>." All you had to do was type that sentence and it wrote basically what you would have written, but instantly.

> Literally imagine if you could type as fast as you could think

This is exactly how vibe coding has been feeling to me lately, I do read all the code while it writes it, and I command the AI to write/edit/fix the code, so its like faster programming but we're still on the director seat

also focusing on logic, and the problems at hand, and not syntax, API, or function signatures, allows one to build at much faster speed and focusing on architecture and actual UX and not just code

In think the people having success, probably have more experience with them. It sounds like "I tried using one of these new horseless carriages and it didn't go well, these things are useless"

> Wild. I evaluate LLMs about once per year, and can't wait for the generative AI bubble to burst.

Strange thing to respond to people having great success with it. You clearly want it to fail, but why?

https://esgnews.com/ai-boom-drives-150-surge-in-indirect-emi...

Not to mention the ethical / copyright / misbehaving scrapers.

“Haters gonna hate”, as the old saying goes.

It just feels like one continuous no true scottsman argument. Oh, you used tech X? Oh no, you gotta use the latest and greatest Y, that's what really makes the difference. 2 weeks go by. You're having all those problems with Y? Oh but that's because you're not using the latest and greatest Z, that makes all the difference, that's where it's really at. Oh, you're not using Z the way I use it? No, you can't do that, you have use it in the special way I use it, that's how it'll work. Oh, that still has problems? That's because you're not using the just-released super-XYZ model, that's really different! Rinse and repeat for many months now.

I had same experience with Windsurf since December. Their slogan was "Experience a true flow state" and I though it was spot on.

These days, with explision of options and alternatives and visible augmentation of their skills (tasks orchestration, mcps, etc) I have temporary reverse of that feeling as I struggle to settle on one approach/tool/editor, and always in half-baked experiementation stage with these tools, that also evolve quicker that I can try them out.

> Claude just tears through problems at breakneck speed. And you know what? It's actually fun again! I forgot how enjoyable coding could be when you're not getting bogged down in the tedious stuff.

yes I've been addicted to vibe coding too but i don't share the sentiment here.

This only holds true as long as you don't run into a bug that llm throws up its hands. Now you have no option but to read and understand code.

At no moment, you can 100% delegate the validation of the information you receive. That’s also valid with humans, feelings and thoughts.

You're a young guy that just dabbled in coding or are you a senior software developer?

I'll add to the sibling comment and say I've been writing software for money for 25+ years, have a CS degree, and have found immense leverage with these tools. I put in the time on hobby projects over the past couple years to figure out how best to integrate it all into my work, and now I'm in a place where it's saving me significant amounts of time every time I produce code, and I'm getting the quality of results the project demands. I use gemini-2.5-pro, claude-4-sonnet, and o3 for different purposes, and have a variety of techniques to avoid pitfalls and get the results I'm looking for. There are a lot of ways to unsatisfactory results, but it's possible to get usable results that save time. I've shared my enthusiasm and seen other devs dabble, get poor results, and go back to their practiced methods of writing software–so I'm not surprised to see so many skeptics and naysayers. It isn't easy or obvious how to make this stuff work for you in larger codebases and for meatier problems. That doesn't mean it's impossible, and it doesn't mean it's not worth it to climb the learning curve. As the models and tools get better, it's getting a lot easier, so I suspect we'll see the number of people denying the utility of LLM-generated code to shrink. Personally, I'd rather be reaping the benefits as early as possible, because I can get more stuff done faster and more pleasantly.

Hello could you tell us what makes you use all of gemini-2.5-pro, claude-4-sonnet, and o3 for different purposes?

I think more often you'll find it's the mediocre coders (like myself) that have trouble using AI. The software developers and CS majors just know exactly what to tell it to do and in the *exact* language it could best be understood. That's just my experience.

Also, I get caught up in multiple errors that will never go away and, since I'm stepping out of my wheelhouse with libraries or packages I'm completely unfamiliar with, I'm completely helpless but to diagnose what went wrong myself and improve upon my code prompting skills.

Don't get me wrong. AI makes possible many things for me. However, I think professional coders probably accomplish much more.

If you've mentored junior devs, talking to the AI in such a way that gives good results is pretty similar, so that may be why.

Knowing how to talk to your wife, your kids and your AI are key to a happy life :)

I'm not OP but my experience with Cursor is similar. I have a B.S. in computer science from UW-Madison and have been a full-time professional software developer since 1998. This stuff is the real deal. I mostly see people not willing to put in the time to learn. There is a big learning curve here--don't let the fact that it's English trick you into thinking there's no skill involved. Your experience is actually what makes this work; greener devs will be unable to get the AI out of a rut or keep it on the straight and narrow, but an experienced dev can sprinkle in some occasional wisdom and get the machine going again. This stuff is fool's gold for "vibe coders" but rocket fuel for experienced developers using it as a tool.

Idk, I’ve been doing this for 15 years professionally and many years before and it’s still amazing to me

Senior developer, decades of experience

Weird, it doesn't even generate comments in the right language when I try to use it.

I'm a marketer. I write a lot. GPT-4.5 is really good at natural sounding writing. It's nearing the point where it would be worth $200/mth for me to have access to it all the time.

I used the GPT-4.5 API to write a novel, with a reasonably simple loop-based workflow. The novel was good enough that my son read the whole thing. And he has no issue quitting a book part way through if it becomes boring.

I guess I don't really understand why. I'm a writer. The joy in storytelling is telling a story. Why outsource that to a bot?

Books create joy for people other than the authors. The joy isn't confined to the writing process.

No, but knowing that a book was written by a bot would hinder my enjoyment of it to the point that I'd drop it.

I’m curious: what was the novel about?

It's a comedic adventure novel set in the Minecraft universe.

Actually I forgot there's a second one he read all the way through, for which he defined the initial concept and early plot, but then the rest of the plot and the writing were all done by GPT-4.5.

The code is kind of basic, and each chapter is written without the full text of prior chapters, but the output isn't bad.

https://gist.github.com/rahimnathwani/41e5bc475163cd5ea43822...

Very fascinating, I tried doing the same years ago with a simple Markov chain model. The biggest problem back then was inconsistency. I'd love to read a chapter of the Minecraft or hard magic / sci-fi books to check out the writing.

Email in profile.

Not having access to earlier chapters is a terrible thing, but maybe possible if you aren’t too bothered by inconsistency (or your chapter summaries are explicit enough about what is supposed to happen I suppose).

I find the quality rapidly degrades as soon as I run out of context to fit the whole text of the novel. Even summarizing the chapters doesn’t work well.

Yeah this is true. I could have sent the entire book up until that point as context. But doing that 100 times (once per chapter) would have meant sending roughly 50x the length of the book as input tokens (going from 0% to 100% as the book progressed).

This would be fine for a cheap model, but GPT 4.5 was not cheap!

I would have liked to have fewer, longer chapters, but my (few) experiments at getting it to output more tokens didn't have much impact.

Yeah, that’s what I eventually ended up doing. Quality and cost both went through the roof. To be fair, Claude is good about caching, and with a bunch of smart breakpoints, you pay only 10% for most generations.

If everyone is as good as you , how much will your work cost?

A better question might be: "If everyone is as good as you, how much will you be worth in the marketplace?"

Well, an even better question might be: if everyone is the same, what does it take to be exceptional?

I'm firmly convinced that being able to troubleshoot code, even code generated by LLMs, and to write guidelines and tests to make sure it's functioning, is a skill of a shrinking pool

For smaller stuff, great. Everyone's the same. The second your application starts gaining responsibility and complexity, you're going to need to be able to demonstrate reproducibility and reliability of your application to stakeholders.

Like, your job increasingly will be creating interface checkpoints in the code, and then having the model generate each step of the pipeline. That's great, but you have understand and validate what it wrote, AND have a rich set of very comprehensive tests to be able to iterate quickly.

And as mentioned, on top of that, large swaths of the field of new people have their brains completely rotted by these tools. (certainly not all new/young people, but i've seen some real rough shit)

If anything, I see a weird gap opening up

- people who dont adopt these tools start falling out of the industry - they're too slow

- people who adopt these tools too early stop getting hired - they're too risky

- people who have experience in industry/troubleshooting/etc, who adopt these tools, become modern day cobol programmers - they're charging $700 an hour

the real question to me is this: does the amount of people taken out of the pool by being slow or risky due to these tools, outpace the reduction in jobs caused by these tools?

> I'm firmly convinced that being able to troubleshoot code, even code generated by LLMs, and to write guidelines and tests to make sure it's functioning, is a skill of a shrinking pool

Well, today only scientists can make stone tools.

I’m not sure the point you’re trying to make but I’ve had so many junior level interviewees and interactions where they are unable to do anything without an LLM coaching them the whole way. This is dangerous!

It’s like if I was hiring a mathematician. I’d expect them to use a calculator or CAS package but I’d also expect them to be able to do everything by hand. I wouldn’t ever waste their time by making them do that, of course.

> I’m not sure the point you’re trying to make

I was trying to say that dropping old technologies isn't always bad.

> It’s like if I was hiring a mathematician.

Do you expect candidate to memorize all theorems up to date. Usually people forgetting things they don't actively use. But they are able to refresh their knowledge if needed. I've learned quite a lot, but no, I don't remember even key theorems from partial differential equations (used them in my diploma). I can refresh and relearn quickly, I'm sure.

Using LLM without understanding disqualifies the candidate, even monkey can do it. But if he deeply understands the subject and uses LLM for like handbook for minor details.. that's different.

> Do you expect candidate to memorize all theorems up to date.

Completely missing the point. I expect them to have enough knowledge to briefly study the theorems and understand how to apply them. I’m not trying to quiz people, I’m trying to get things done - and done well.

And for the stuff I’m doing, it’s required that any engineer understand what they’re building and why.

> Using LLM without understanding disqualifies the candidate, even monkey can do it. But if he deeply understands the subject and uses LLM for like handbook for minor details.. that's different

The problem is that they don’t understand the subject and overly rely on LLMs. Completely falling apart during in person interviews. Surface knowledge of everything and no depth.

Using LLMs isn’t inherently bad but I’ve seen severe side effects from students and junior engineers who over rely on it.

Approximately $200/month apparently.

It probably would be just like with developers.

A great developer + an AI = productive.

A shitty developer + an AI = still shit.

AI does not make all developers the same. And it doesn't make all marketers the same.

I wish all LLM-written marketing copy had disclaimers so I knew never to waste my time reading it.

I think writing claude sonnet 4 is more human - like.

Nope, this is exactly how the Internet at large grew up.

First, the breathless nerds. Then, the greater swath of nerds (where we are). And this is when people start to get excited in various degrees while others say stuff like "no one will ever want to fuss with dialup and a second phone line" or "no one will ever put real info or use credit cards online".

Then a couple years later, grandma is calling you over to fix her Netzero and away we go...

Why is that concerning? I think it's amazing. Also these things will improve other products indirectly.

Because it shows it's a bubble, and when a bubble of this size, invested by that many actors, pops, it has a devastating impact on everyone.

Eh, those are early adopters.

My partner is not a coder but uses copilot a lot.

Compare this to blockchain, which never did anything useful for anyone after 20 years.

Wrong. Blockchain has actually found successful product market fit in several areas:

- ransomware payments

- money transfers for online and telephone scams

- buying illegal drugs online

- funding North Korea’s government

Well, yes :)

But I was talking within the same context as the thread, which is business.

But those are examples of business. ;)

(I apologize for being a smart aleck.)

very funny, let's not forget:

- avoiding monetary tyranny in not-so-well developed authoritarian countries

maybe not so important for you, but for some people it is simply a matter of acquiring food and medicine, because a working member of their family has just one way to support his relatives by sending them money from abroad, and it is bitcoin

- bribing the USA’s president

> and ultimately meld together to be able to achieve tasks on time horizons of multiple hours

It's already possible to achieve tasks on a time horizon of multiple days if you put the LLM into a sufficiently structured workflow (where you have a separate program that smartly manages its context). E.g. a standards-compliant HTTP 2.0 server where the code is 100% written by Gemini Pro (over 40k lines of code total, including unit tests, in around 120 hours of API time): https://open.substack.com/pub/outervationai/p/building-a-100...

This is very interesting, and nice learnings in there too, thank you for sharing! It seems the author monitored the LLM, stopped it from going off-track a few times, fixed some unit test code manually, etc. Plus this is strictly re-implementing a very well-specced library that already exists in the same programming language. So I think it's still a bit hard to say we can let an LLM work for multiple days, if we imply that this work should be domain-specific to a particular company. But it's very promising to see this was possible with very little interaction!

i think its very interesting how openai basically owns/leads in every single vector you* listed. have they missed/been behind on something?

*i would have come up with a similar list but i dont trust my own judgment here. maybe i'd sub in claude code vs codex but jury is a bit out still on that

I think OpenAI is the first 100% AI-focused company to throw this many engineers (over 1,000 at this point?) at every part of the agentic workflow. I think it's a tremendous amount of discovery work. My theory would be that once we see what really works, other companies can catch up rather quickly, using far fewer resources to do so.

Google seem to be making a lot of progress on agentic too, not only with Mariner, but with Project Astra, Call For Me, and their Agent2Agent protocol. There's probably much more to come here.

Oh and OpenAI is clearly willing to spend a lot of money to push this technology a bit further. If you look at the logs of Codex, it appears to be using a very strong (read: expensive) reasoning model to basically brute force the use of a VM. If you have a follow-up question in a Codex task, they just casually throw away the old VM and spin up a new one, running all setup again. If you compare this to e.g., Cursor, I'd wager Codex costs 5-10x more to perform a similarly sized task, though it's hard to tell for sure.

Why aren’t they using gvisor for something like this?

They probably are, or at least will! But for now it seems like the first version that works end to end and it certainly feels like it’s a standard VM spinning up a Docker image. There are lots of more specialized solutions out there like CodeSandbox SDK which lets you prepare a devcontainer that can fork and spin up for a new PR in less than a second. So if it’s not Codex, _someone_ will nail this experience. Cursor’s new background agents could be it though I don’t enjoy them currently. And I also get the feeling they too spin up cloud VMs “the old school way”.

Agents that can receive and make phone calls end to end and perform real world actions (I use Simple AI to not have to talk to airlines or make food orders etc, it works well most of the time

Isn't this more a problem created by them doing garbage automations over anything really solved. Wow Disney could solve fast pass feeling. It's not a problem it's a feature.

Maybe for support but it’s a real world problem unrelated to language models that they do help me with. And ordering food at a restaurant is an age old problem, I just don’t enjoy making the call personally so I got value out of using a voice agent to do it for me. I asked the staff at the restaurant and they said it was laggy so we still have to improve the experience a bit for both parties to enjoy this type of experience, not saying it’s perfect.

Could you elaborate how you actually order food like this?

“Call RestaurantName and order two massaman curry one with chicken and one with veggies plus rice for pickup”

Then I get a push notif a few minutes later with the ETA.

Just wait until everyone you'd want to talk to deploys their own adversarial agents!

Thanks for posting this! I haven't used ChatGPT much due to worries of something like this possibly existing.

Curious if this make you less or more likely to use OpenAI products in the future?

I don't care that much.

This level of knowledge about me can also be easily found on the internet.

I'm also working almost entirely on open-source software so I'm happy if the AIs know more about my projects.

But this, of course, only applies to me.

Fair enough. The majority of it does seem useful.

From what it logged about you, it does seem you're working on some cool stuff too!

I found o3 pro to need a paradigm shift, where the latency makes it impossible to use in anything but in async manner.

You have a broad question, likely somewhat vague, and you pass it off to o3 with a ton of context. Then maybe 20 minutes later, you're going to have a decently good answer. Definitely stronger than any other models - it genuinely has taste.

Yet, the scary thing here is that increasingly I'm starting to feel like the bottleneck. A human can only think about so many tasks in parallel and it seems like my contributions are getting less and less important with every model upgrade.

Every now and then I question why I'm paying $200 for the max plan, but then something like this comes out and makes it a no brainer.

This is gonna keep happening with every AI advance until humans are an absolute bottleneck in every domain. May take a bit of time for some professions, but the writing is on the wall. This will be the greatest shift in human history, and I think a lot of people will have trouble grappling with it because its not fun to think about being made irrelevant.

The only thing that will slow AI down is massive universal international regulation. Human intelligence really isn’t the be all end all to intelligence in general, it’s just a stepping stone. I feel many on this site don’t want to accept this because their intelligence has been such a valuable tool and source of personal pride/identity for them for so long.

What is all of this for if the result is that human beings are "made irrelevant"? If these LLMs truly become as game changing as so many say they will be, then can we agree that it's time to stop thinking that a person's worth equals their economic output?

I agree with you, the problem currently is that the balance of power has shifted so far in favor of the 0.1%. And those people will not want to give up the power that they already have.

I fear for a future where the technocrats win out and we end up in an "Altered Carbon" scenario. We are on the precipice of AI and robotics equalizing the playing field for everyone, but only if the power is held by the people and not the few at the top with the most resources.

Not sure how to steer the ship in that direction, but I do have a few ideas...

No, that won’t happen, because these tools are being built based on investments in private goods.

It would be something if there were national level LLM tools, owned and operated as commons.

Things that were once operated as commons became private goods. There is no reason that it can't go the other way.

I can't tell if this is satire or end-stage depoliticization in action. Yeah we are just gonna nationalize things again, no big deal.

If the change is an extinction level event for the state, nationalization is a sure bet

Neither, it is just a statement of fact.

> What is all of this for if the result is that human beings are "made irrelevant"?

I think your views on this will radically differ if you earn 200k a year versus 2k a year.

Which is maddening. Too many people lack class consciousness.

An engineer making 200k a year has more in common with someone making 2k a year, than they do with the Elon Musk's of the world.

This delusion is rampant in professional spheres like medicine and tech.

> An engineer making 200k a year has more in common with someone making 2k a year, than they do with the Elon Musk's of the world.

No they don't. Only someone making 200k could say that.

If you make 200k a year, you're not even in the top tax bracket of the US. On 200k alone you can hardly even afford a SFH in SV, NOVA, and NYC.

Meanwhile Elon Musk's net worth can swing 200+ million in a single day. He could buy up an entire neighborhood in those same zip codes you'd hardly be able to break into.

So how are you "closer" to Elon Musk exactly?

It is definitely past time to start thinking outside of the economy.

Although must we deal in "worth" at all at that point? If two people have conflicting visions, it shouldn't be the one who is "worth" more that gets their way, it should be the one whose vision is most appealing to the rest of us.

No, I disagree, and for everyone who bemoans capitalism or the power of money, its important to understand the foundational arguments from which economics is born.

Wants are infinite, and resources limited. Economics is the objective methods to order a system to achieve subjective ends.

For better or worse, money is a medium of exchange and signal of what people are willing to allocate for their needs. Unless you create economic markets, information markets, and political systems that are built to handle the forces being harnessed by society, you have failure states.

In other words, taxes need to bleed of wealth, to ensure that it cannot create advantage in other fields (media, politics), breaking the even playing field in those other economies.

You are begging the question by relying an unproven basis for your argument. Why do economies have to be based on free market capitalism?

Free markets are superior to planned economies because they’re able to instantly respond to consumer preferences, resulting in efficient allocation of resources.

On a side note, I’m not sure why HN is often hostile to economic arguments. Economics is a well-established science.

Horses were superior to steam engines for 100 years. It takes time for technology to improve, and money is a technology.

As technologists, we understand the the need for a new major version here and there. A breaking change where the new thing is not compatible with the old. Economics as we know it smells overdue.

The particular bit that doesn't seem to be fitting the bill anymore is "value". Back when more economic activity was undeniably a good thing... Back when the majority of our resources were spent fending off hunger, or exposure to the elements, or illness, we had enough of a common enemy that we could get by with a single untyped primitive notion of value. However much we disagreed, we still agreed enough for that to work.

But now we're able to handle the basics well enough that we spend the majority of our resources fending off each other. A single fungible notion of value feels awkward. When I accept a dollar from somebody I'm not sure whether I've helped or harmed myself by doing so because its just as likely that they made that dollar by degrading the water I drink or some other activity that's worth way more than a dollar for me to prevent. We lack shared values but still share a notion of value, and it's not working out.

So perhaps instead of "thinking outside the economy" I should've said "Update the economy to account for more". Whatever words you prefer for it, drastic change is on our doorstep.

Just wanted to note that free markets are separate from capitalism. Free market socialism has existed here and there as well.

Economics is not capitalism though. They are not synonyms.

I am making a defense of economics, not capitalism.

I like markets, and would laugh if anyone went ahead and tried to make a purely capitalistic economy. Fair, well regulated economies, work.

>Fair, well regulated economies, work

There is not a single fair, well regulated economy in the world. Private interests of those with large amounts of capital skew the markets to their favor.

This is a nirvana fallacy. “There aren’t any that are perfect so why try?”

How fair and well regulated is not a binary option of it is or it isn’t and we can continuously try to make things better.

>we can continuously try to make things better

Who is "we" here? Because the current system is ran by people who have a vested interest in keeping things the same.

Also, I disagree on my comment being a fallacy. I'd almost argue the comment I replied to is a fallacy because it's comparing a theoretical well regulated market to the reality of what we actually have.

It's clear to me that such a thing could never truly work because it would require near omnipotence by whomever the regulating body is in order to prevent actors gaming the market.

Have you seen one of those lately?

Don’t know, but Europe seems to be doing better than the US in that regard. So perhaps some countries in the EU?

Humans have more access to the real world. These models have to tokenize everything and put it into words, but so much information is outside of words. These models may well be super intelligent but their intelligence is locked inside of a cage (the tokenizer).

Even in the world where AI has full control of lights out factories (again, doubt it. something goes wrong at the factory, you gotta send a guy in), human beings still need to look each other in the eye and communicate, they need to touch each other. Not only that, they need to be seen and acknowledged by other human beings.

"AI" cannot ever replace this. People whose intelligence is their pride/identity kind of miss this. Stupid people are capable of loving each other more deeply and more completely than any machine ever will love them.

You basically just said people will be the janitors, the on-site fixers, and the personification of decisions and that they will still be able to live fulfilling lives in the real world. I think that is perfectly in line with what the parent wrote.

All those things could be done by humanoid robots. AI models aren’t limited to words, as we’ve seen with video models. Gpt 4o, which has been out for over a year, is natively multimodal. Robotics companies are training robots to take in all the data they have avaliable, video, audio, and interpret them all together in context. There is the core substrate of tokens, yes, but largely it is just a standard “bit” level of information for AI brains, not some essential limiter that will keep AI from understanding all the soft, abstract stuff that humans can. If you look at o3 now, just feeding it images, it clearly now can reason in a way closer to humans than a calculator is to it.

What a load of guff.

AI models still produce galling inconsistencies and errors for me on a daily basis.

Same.

I find LLMs to be useful, but my day to day usage of them doesn't fit the narrative of people who suggest they are creating massive complex projects with ease.

And if they are, where's the actual output proof? Why don't we see obvious evidence of some massive AI-powered renaissance, and instead just see a never ending stream of anecdotes that read like astroturf marketing of AI companies?

Speaking of which, astroturfing seem like the kind of task LLMs should excel at…

I think it's easy to ignore all the times the models get things hilariously wrong when there's a few instances where its output really surprises you.

That said, I don't really agree with the GP comment. Humans are the bottleneck if we knew these models get things right 100% of the time but with a model like o3-pro it's very possible it'll just spend 20 minutes chasing down the wrong rabbit hole. I've often found prompting o4-mini gave me results that were pretty good most of the time while being much faster whereas with base o3 I usually have to wait 2-3 minutes and hope that it got things right and didn't make any incorrect assumptions.

What good is intelligence if there is nobody with the money to pay for it? We run our brains on a few thousand calories a day. Who is going to pay to provide the billions of calories it takes to run/cool GPUs all day long if there are no humans with marketable skills?

“No marketable skills” seems pretty unlikely if you look beyond office work.

Genuine question--I've seen this thrown around a lot. Do you count yourself in this hypothetical situation where society returns to physical labor, or do you think you're immune from being automated?

Since there are excellent educational resources available online, I've sometimes wondered what it is that teachers do that couldn't be done by computer software. But it seems clear that they're somehow necessary? In theory, a bright kid with access to the Internet should be able to teach themselves, but most kids won't learn much that way.

We're going to see more jobs automated, and lots of jobs will change, but I think lots of jobs will still be around for similar reasons. Even if it's not what we'd normally consider physical labor, there's something about in-person interaction that's not easy to automate.

Independent, self-sufficient adults who could and want to get by with just machine interaction are a minority.

AIs will pay other AIs through various means of exchange

Assuming AI need humans in that way is like being a tribe of monkeys and saying

“What good is being human if they don’t have bananas to pay? Monkey only need banana, humans need clothes, houses, cars, gas, who is going to pay the humans bananas if monkeys have all the banana?”

I think too many people call this intelligence, and it results in intuitions that are useless and waste time, pushing the day we understand this moment further into the future.

The best I’ve got is theres 2 frames of assessment people are using:

1) Output frame of reference: The output of an LLM is the same as what a human could make.

2) Process frame of reference: The process at play is not the same as human thinking

These 2 conversation streams end up with contradictions when they engage with each other. Yes, the tools are impressive. The tools aren’t thinking. etc.

A useful analogy is rote learning - many people have passed exams by memorizing textbooks. The output is indistinguishable from someone who manipulates a learned model of the subject to understand the question and provide the answer.

> unilateral international regulation

is an oxymoron/contradictory

sorry I meant "universal" or "omnilateral"

Did you mean global regulation?

yeah

Yes, people will start asking "when must we kill them?"

> I found o3 pro to need a paradigm shift, where the latency makes it impossible to use in anything but in async manner.

Just like o1 Pro, was the same way. Took some minutes at least to get an answer, so only threw at it what others couldn't solve. o1 Pro is AFAIK the best model for solving things others can't. I kind of feel like you were paying $200/month before but wasn't using O1 Pro at that point, you were kind of missing out :P

Remains to be seen if O3 Pro is better, still evaluating it myself, but definitely true that it shouldn't be used in the same way as faster models.

Interesting. Are you seeing situations where O1 Pro is notably better than O3 Pro?

Kind of sucks they removed o1 Pro from the UI, so can't do side-by-side comparisons, but my experience so far is that they're more or less equal, seems to be a bit faster if nothing else. But personally I'm not seeing a huge difference between o3 Pro and o1 Pro, but also haven't used it more than a few times still.

I have some examples that o1 Pro wasn't able to solve before, should probably give those a try with o3 Pro but haven't had the time yet :/

should still be in the API for side-by-side comparison, but I’ve never tried the -pro models in the API.

Do the coherent extrapolated volition thing: "o3-pro, please reinterpret the prompt and do what I would have actually requested instead if I was 50 IQ points smarter."

I’d be curious to see benchmarks but this kind of query rewriting seems almost guaranteed to already be baked into the model.

is there documented/writeup on how this improves thinking?

I got frustrated with the new o3-pro mode today. I just wasted a few hours of my day waiting 15-20 minutes for answers that were totally out of line with the workflow I've had since the first o1-pro model came out. It's a completely different beast to work with. It feels like it hits output limits way easier, and you have to work around it. Today after I finally gave up, I just told the model I was disappointed and asked it to explain its limitations. It was actually helpful, and told me I could ask for a download link to get a file that wasn't cut off. But why should I have to do that? It's definitely not more user-friendly and totally the opposite experience as working with Google Gemini 2.5 pro. Honestly, this experience made it obvious how much harder OpenAI's models are to work with now compared to Google's. I've been using Gemini 2.5 Pro and it's super hard to find its limits. For the $20 I spend, it's not even a competition anymore. My new workflow is clear: throw everything at Gemini 2.5 Pro to get the real work done, then maybe spot-check it with the OpenAI models. I'll probably just migrate to the top Gemini ultra tier when the “deep thinking” mode is available. I'm just not happy with the openai experience on any of their models after getting used to the huge context window in Gemini. OpenAI used to at least keep me happy with o1-pro but now that they removed it and o3-pro kind of sucks to work with taking 20 minutes to output and have lower confidence in the time spent, I don’t think I have a reason to default to them anymore. Gemini is definitely more user friendly and my default option now.

What seems clear is there is no consensus. Gemini 2.5 Pro just seems consistently worse to me, but I’ve seen others sing its praises. This might be more like iPhone vs Android than a true stack ranking of models.

Sometimes it's great, sometimes it's not. Depends on the tools you're using too, I guess. Like when using Roo-Code, Gemini 2.5 Pro still gets confused by the wonky diff format Roo-Code wants it to use. It'll keep messing up simple edits, and if it happens once, it'll happen again and again, cause it's multi-shotting itself to make mistakes.

I don't have that with Claude-Code, it just keeps on chugging along.

One big difference there though: I got the Claude-Code Pro Max plan (or whatever it's called). I now no longer have to worry about the cost since it's a monthly flat-fee, so if it makes a mistake it doesn't make me angry, since the mistake didn't cost me 5 euros.

I am using an MCP server that adds Gemini & O3 to Claude-Code, so Claude-Code can ask them for assistance here and there, and in this Gemini 2.5 Pro has been such a great help. Especially because its context size is so much larger, it can take in a lot more files than Claude can, so it's better at spotting mistakes.

It depends on the task. Claude 4 is better at coding (haven't tried claude code, just sonnet, but you can tell). However when it comes to using an LLM to develop your thoughts (philosophy/literary criticism), I found Gemini (2.5 pro) to be better. A few days ago I was trying to get Claude to reformulate what I had said in a pretty long conversation, and it was really struggling. I copy-pasted the whole conversation into Gemini and asked it to take over. It absolutely nailed it in one shot.

I found all recent models to be "good enough" for my use (coding assistance). I've settled on just using Claude 4. At the same time the experience also makes me less worried about this tech making programmers obsolete...

Gemini 2.5 pro has been consistently excellent for me, when it works. It sometimes just spins and spins with no results but when it comes with something, it has been pretty good.

I find o3’s coding output is just wonderful. It’s tidy, thoughtful, well commented. But if I need to grok an entire repo to ask a complex question, I paste it all into Gemini 2.5 Pro. Simply wonderful.

By "output limits" do you mean the context window?

> On the other, we have gigantic, slow, expensive, IQ-maxxing reasoning models that we go to for deep analysis (they’re great at criticism), one-shotting complex problems, and pushing the edge of pure intelligence.

I quite enjoy having an LLM write much of my tedious code these days, but comments like this are just bizarre to me. Can someone share a text question that I can ask an expensive slow LLM that will demonstrate “deep analysis” or “iq-maxxing” on any topic? Whenever I ask them factual or discussion questions I usually get something riddled with factual errors or just tedious, like reading an essay someone wrote for school.

I use o3 for my PhD math research. When I am facing a specific problem and I am out of ideas I oass it to o3. It will usually say something with a fair number if errors and eventually claim to have solved my problem in a standard manner, which it almost never does. But that does not mean it is not useful to me. My attention is light a flashlight illuminating a tiny spot in the possibly vast field of methods I could try. Right now my head is full of dispersive PDEs so I will not think of using parabolic regularization. But o3 is more of a dim background light. I am in the end better at using any particular technique that is familiar to me than o3, but in this very moment I can only think of a few options. Sometimes my specific problem is actually naturally tackled by a method I have not considered, and o3 suggests it. If you consider that iq-maxxing or not, in this moment for me it is, because it helps me.

You should also try o4-mini-high. Or, if you have already, I’m curious to hear how they compare for you. I somewhat suspect that o4-mini is better on pure math problems that take more thinking and less world knowledge.

Yea I try them both but I honestly can not tell much of a difference. Subtle things.

I ran into a weird joystick bug the other week, and I wanted ChatGPT to figure out the exact code flow of how a specific paramter is set.

I had it analyze different related libraries, and it zeroed in on SDL and Wine codebases, and it found the exact lines of code related to the logic error in Winebus.

It really helps me dig deep for certain hard to track bugs.

I really like using o3 to help with thorny architecture problems by researching existing related solutions on the internet, distilling them, and comparing trade-offs with me

This is just a trivial way to illustrate some capability, it is not meant to be deep or insightful or an end-task in itself.

this is good enough for me, even if its not solving your problem. it gives you option and fills some information void

The one I asked o3-pro yesterday was "Research the annual smoking tobacco production in Soviet Union 1939-1958 and plot it in a graph versus male population size"

And how was result? Did you verify that it found reliable source of data?

This is the kind of thing I absolutely don’t trust it for. It generates a very convincing-sounding report but for a lot of tasks I’ve found the numbers won’t reasonably match up to my own.

It's a bizarre request anyway. What could you possibly learn from such a graph. I guess it's a joke of some kind but it's rather obscure.

It's really obvious if you pause and think. Or maybe just ask an LLM.

validating the info it gives in a response to a question like this sounds like it would be extremely tedious, unless you already had a hand-curated data set to answer it.

did you? did the data match?

I don't have any good idea of what are "good" prompts for demonstrating such models. But what I would ask such a model is the following. I have no idea if it would fall on it's face or not.

Can you write a version of Chorin's projection method for the Navier-Stokes equations that is both explicit and second order in time?

Ideally the model should not need a more detailed prompt than this. A first-year grad student in numerical analysis certainly would not.

ChatGPT wrote this article

Part of me hates how certain ways of writing have been designated as hints that something was written by AI… I love using em dashes, for example. But yeah, ChatGPT models tend to overuse weird abbreviations of common words in a way that humans never do.

I’d say “in an eval” when talking on Slack with very close coworkers, but _never_ on a public post.

Still, I don’t want to make accusations based on writing style, because like I said, I have my own idiosyncrasies that common models coincidentally share.

Correction: I wasn’t aware of OpenAI’s “evals” tool. If that’s the kind of thing the author was referring to, I may have misjudged.

Miracle models that are so good at helping us with our writing, yet we still use it's as a possessive form.

Maybe use of spell-checkers will finally catch on when they are AI-based. ;)

I'm on the fence with its/it's... but mostly I think I'd be fine with "its" disappearing. It's almost never ambiguous in writing or speaking given context, and it's a weird possessive-form inconsistency.

Which one is the most inconsistent?

    He  -> His
    It  -> Its
    She -> Her

    He  -> He  is -> He's
    It  -> It  is -> It's
    She -> She is -> She's

The only one breaking the pattern is Her, which instead should be Shes if we wanted to keep things consistent.

All of the pronoun contractions are somewhat inconsistent with noun possessives. So "its", but "the dog's". There's no reason why you couldn't write "it's" for both "it is" and "its". You already write both "the dog's ball" and "the dog's tired", and both "it's" and "it's" are pronounced identically, which doesn't pose any difficulties in speech.

His, her, and my are a different matter, since they are all pronounced differently from he's*, she's, and I'm.

* at least in most accents, "his" uses the kit vowel, while "he's" uses the fleece vowel

Dog's/dogs are ambiguous. It's/its is not.

"Dog's" is ambiguous in itself (dog is / that belongs to the dog), but this doesn't cause problems in practice. It's exactly the same ambiguity as spelling "it's" for the possessive would give. Also, it's / its is only unambiguous in writing. In speech, they are identical, in every accent of English - and yet people understand each other perfectly fine in spoken English, so the ambiguity is not a problem in practice.

tbh I'm not quite sure if you're arguing in favor of switching to "it's" or against. I think against...?

Clearly "x is" is most consistent in that example, implying the possessive form is inconsistent.

Also clearly in a straightforward example

  John possesses -> John's
  The dog possesses -> Dog's
  It possesses -> It's
  Xe possesses -> Xe's

is equally as consistent as "x is", which is more consistent than "Its".

(yes I'm aware there's a proper noun vs pronoun change in there, but I'm not sure that's an argument for "special noun cases are good". they undeniably exist, but should we encourage them?)

Actually if we’re keeping with the pattern it would be Shis

Good catch! Thank you.

Or shits

Does this happen to be the one billionth HN comment?

Believe or not, "it's" as a possessive form came before "its."

Source: https://www.merriam-webster.com/grammar/the-tangled-history-...

She->her (like everything in English) makes a lot more sense if you start in the roots of English. She was “hio” or “heo” and her was “hire”. By the 13th century, the pronunciations of he and heo had converged and become synonyms so “she” was introduced.

She shares a letter with seo, which was the root of both he and heo.

Simple pattern matching really can’t work in English - the roots are way too messy. And it’s absolutely amazing that people can become reasonably fluent if they only start learning as adults.

> The only one breaking the pattern is Her, which instead should be Shes if we wanted to keep things consistent.

It should be "She > Shis" if we want to keep it consistent with "He > His" and not with "It > Its".

I have yet to encounter a case where words need an apostrophe to disambiguate. It’s just an unnecessary exception. Writing is about communication and if everyone knows what you mean without the apostrophe then it adds no value.

Same thing with book authors who have a good idea that can be expressed in 50 pages but for some reason publishers want 180+, so you end up with 130 pages of fluff, wasting everyone’s time.

> It’s just an unnecessary exception.

Had you written this “it’s just an unnecessary exception” you would be talking about a “just an unnecessary exception” that belongs to it. That’s not clear in the slightest. Apostrophes exist for clarity and precision.

I think you meant to criticize “its just an unnecessary exception” and were autocorrected.

Reading it without an apostrophe it looks unusual but the meaning is still very clear.

Further, there are many words like “don’t” and “doesn’t” and can’t” where the apostrophe doesn’t even provide any disambiguating value.

There is "wont" and "cant" but theyre rather rare nowadays. Probably others too, but Im (...im?) not able to remember any easily.

The closest I can think of thats maybe confusing is plurals vs possessive... but thats usually pretty clear from context, and when both are combined its often handled specially and thats weird but not usually confusing - English often has other in-sentence (and in-context) markers for plurality. You can of course construct ambiguous sentences, but thats true of many things that are accepted as "legal English".

It would be a shame to lose y'all'd've though.

https://www.merriam-webster.com/dictionary/wont

https://www.merriam-webster.com/dictionary/cant

No, I’m just bad at spelling poorly. What’s wrong with following the rules of a language? If I don’t use Rust properly, it won’t compile. Why make exceptions for human language?

Human languages have less "rules" and more "patterns that improve communication", and they constantly change. And even languages with like legitimate rules-bodies overseeing it still see variation in normal use.

It's honestly pretty funny to me that apparently this is one of the worst things I've ever said here.

I mean. I don't disagree. But lol

Something I like about this piece is how much in reinforces the idea that models like o3 Pro are really hard to get good results out of.

I don't have an intuition at all for when I would turn to o3 Pro yet. What kind of problems do I have where outsourcing to a huge model that crunches for several minutes are worthwhile?

I'm enjoying regular o3 a lot right now, especially with the huge price drop from the other day. o3 Pro is a lot harder to get my head around.

Yesterday I asked 2.5 Pro, Opus 4, and o3 to convert my Pytorch script from pipeline parallel to regular DDP (convert one form of multi-GPU execution to another). None of the three produced fully correct code. Even when I put together the 3 different versions they produced, and gave it to each model again to analyze the differences, they still could not fully get it to work.

I don't know if o3 Pro would solve my task, but I feel we're still pretty far from the state where I'd struggle to give it a challenging enough problem.

That's not how you do it. Ask it first to create exhaustive tests around the first version. Tell it what to test for. Then, ask to change specific things, one at a time, re-run tests between the steps, and ask it to fix things. Rinse-repeat-review. It is faster than doing by hand, but you still need to be calling the shots.

I just did it myself in the end.

Good for you. OpenAI would rather you rely on it to solve your problems than your own intelligence.

I'm curious how you're prompting. I've performed this sort of dramatic update in both one-shot (Gemini 2.5/o3) and Leader/Agent (ask 2.5/o3 for a detailed roadmap) and then provide that to Claude to execute as an agent.

I find the key is being able to submit your entire codebase to the API as the context. I've only had one situation where the input tokens were beyond o3's limit. In most projects that I work with, a given module and all relevant modules clocks in around 50-100k tokens.

When calling via API, it also means you want to provide the full documentation for the task if it's a new API, etc. This is where the recent o3 price decrease is a godsend.

>I find the key is being able to submit your entire codebase to the API as the context

Am I the only person who works on proprietary code bases? This would get me fired.

In general, you can’t expect good answers if the AI can’t see your actual code. Most people trust that their SaaS products are not going to steal their code, as evidenced by the many customers of Github.

You tried to one-shot it? Because context and access to troubleshooting tools is of utmost importance to get good results.

Would o3 pro be the first one that can reliably understand a gigantic congressional bill, to the point where it could analyze and warn of side effects?

Would require the bill to be short, or otherwise made ingestible. And also would require an analysis of relevant inter-related statutes and precedents.

Legal analysis is challenging because it's like wordier code.

the "Big Beautiful Bill" is 350K tokens. O3 Pro's context window is 200K, but you also lose performance as you get closer to the max.

It could analyze a section but you still have the challenge of finding relevant laws and precedents.

Oh that's a really interesting test case for it.

Same here, I’d be very interested to learn how others decide what model to use for which tasks.

I find these minutes-long iterations so painful that in practice I always go for the fast non-reasoning models.

Imagine a tricky distributed systems problem where you feed all of the context of your setup to the LLM and it uses the advanced reasoning to diagnose possible avenues. I did that recently with a frontier model to unwrap some very tricky istio related connection pooling issues causing syn/ack floods.

For coding I usually use the fast frontier model like o4minihigh, but I bust out the fancy research models when I want things like general architecture and design feedbacks that require broader advanced reasoning

I don't often have LLMs write a lot of code for me, but when I do, I don't mind waiting a couple more minutes for a result that will waste less of my time in debugging when I try to use it.

Also it's useful to have models review code that I wrote -- in some cases years ago -- to uncover old bugs. Current models are generally far too eager to say "Yup! Looks good! You da man!" when there are actually serious flaws in the code they are reviewing. So again, this is a task that justifies use of the most powerful models currently available, and that doesn't have to run in real time.

Random thought: dump your knowledge base into it (Obsidian, ...) and ask it to reorganize it, delete duplication, obsolete stuff, optimize it.

Or tell it what you know about non-programming subject X, and ask it to explain it to you such that you understand it better.

Or for coding: ask it to look at your code, and suggest large scale architecture changes.

For these kinds of tasks, the models are still lacking.

Something that comes to mind – I code with for platform that doesn't have a lot of source code or documentation simply available online for training; I have to provide a lot of context. A lot more inference lets it combine its general knowledge about systems programming to this really niche domain, with a lot less hallucination and a lot more systematic reasoning.

I benchmarked it on four of my benchmarks so far. Got first place in two of them:

https://github.com/lechmazur/confabulations

https://github.com/lechmazur/nyt-connections

https://github.com/lechmazur/generalization

It seems like you often have LLMs grading each other. Aren’t you concerned that some models may not be “smart” enough to grade a smarter model appropriately?

Using LLMs for evaluating LLMs is incredibly common.

The point isn't in having a "perfect" evaluator, but in having a cheap and somewhat consistent evaluator.

This approach holds up well enough... as long as you don't try to use it for RL. If you do, chances are, you'll end up with an adversarial LLM that aims solely for breaking and saturating the evaluator.

But I feel like the evaluator should generally be stronger/better than what its evaluating. Otherwise you risk it evaluating at a lower level, while the better LLM is writing with more nuance that the lower LLM doesn't pick up on.

I've seen some places, e.g., NY Times, use expert panels to review the results from LLMs. For example, getting the author of a book/essay to evaluate how well the LLM summarizes and answers questions about the book/essay. While it's not scalable, it does seem like it will better evaluate cutting edge models.

I’m not sure I would use “consistent” to characterize LLMs

> Trying out o3 Pro made me realize that models today are so good in isolation, we’re running out of simple tests.

Are Towers of Hanoi not a simple test? Or chess? A recursive algorithm that runs on my phone can outclass enormous models that cost billions to train.

A reasoning model should be able to reason about things. I am glad models are better and more useful than before but for an author to say they can’t even evaluate o3 makes me question their credibility.

https://machinelearning.apple.com/research/illusion-of-think...

AGI means the system can reason through any problem logically, even if it’s less efficient than other methods.

The towers of Hanoi one is kind of weird, the prompt asks for a complete move by move solution and the 15 or 20 disk version (where reasoning models fail) means the result is unreasonably long and very repetitive. Likely as not it's just running into some training or sampler quirk discouraging the model to just dump huge amounts of low-entropy text.

I don't have a Claude in front of me -- if you just give it the algorithm to produce the answer and ask it to give you the huge output for n=20, will it even do that?

If I have to give it the algorithm as well as the problem, we’re no longer even pretending to be in the AGI world. If it falls down interpreting an algorithm it is worse than even a python interpreter.

Towers of Hanoi is a well-known toy problem. The algorithm is definitely in any LLM’s training data. So it doesn’t even need to come up with a new algorithm.

There may be some technical reason it’s failing but the more fundamental reason is that an autoregressive statistical token generator isn’t suited to solving problems with symbolic solutions.

I'm just saying ~10MB of short repetitive text lines might be out of scope as a response the LLM driver is willing to give at all, regardless of how derived

In the example someone else gave, o3 broke down after 95 lines of text. That’s far short of 10 MB.

You are the only person suggesting that o3 is AGI or even an approach to AGI. They’re different beasts entirely.

This isn't my language (saw it on a youtube video but agree with it) -- LLMs are not calculators. It's as simple as that.

If the LLM can complete the task using tools, then it's a pass.

Apples team went out of their way to select tests that LLMs would struggle with and then take away tools -- and then have the audacity to write that they're surprised at the outcome. Who would be surprised? No one using AI since GPT-4 expects them to be calculators or algorithm executors.

You want the LLM to be smart enough to realize "I can't do this without tools", grab the tool, use it correctly, and give you the actual correct answer. Preventing LLMs from using tools or writing and executing code -- then you're intentionally crippling them.

I think that’s perfectly reasonable for problems that have already been solved and for which tools already exist. But there are a lot of problems for which tools don’t exist and will need to be developed.

In other words, being able to go to the produce aisle means I don’t need to know how to farm, but it also doesn’t make me a farmer.

I doubt I could reliably solve Towers of Hanoi in my head for more than 3 or 4 discs.

Fair point, but the idea of these “reasoning” models is that they have a scratchpad to figure it out before giving an answer.

It single-shots the towers of Hanoi https://chatgpt.com/share/6848fff7-0080-8013-a032-e18c999dc3...

It’s not correct.

In move 95 the disks are

Tower 1: 10, 9, 8, 5, 4, 3, 2, 1

Tower 2: 7

Tower 3: 6

It attempts to move disk 6 from tower 2 to tower 3, but disk 6 is already at tower 3, and moving 7 on top of 6 would be illegal.

In fact this demonstrates that o3 is unable to implement a simple recursive algorithm.

I find it amusingly ironic how one comment under yours is pointing out that there’s a mistake in the model output, and the other comment under yours trusts that it’s correct but says that it isn’t “real reasoning” anyways because it knows the algorithm. There’s probably something about moving goalposts to be said here

If both criterion A and B need to be satisfied for something to be true, it’s not moving the goalposts for one person to point out A is not true, and another person to point out that B is not true.

This isn’t reasoning at all. It’s applying a well known algorithm to a problem. It literally says “classic” in its response.

It is “reasoning” in the same way that a calculator or compiler is reasoning. But I checked the solution, it’s actually wrong so it’s a moot point.

What will really bake your noodle is when you realize that just because the model's answer is wrong doesn't mean it didn't use reasoning to reach it.

Is your reasoning always perfect? No? Ever get partial credit on a test question in school? Yes? Well, maybe don't expect perfection from a model that didn't exist 5 years ago, that was considered impossible 10 years ago, and that would have gotten you burned as a witch 15 years ago.

Nobody claims that o3-pro is AGI, or even that it is going to lead up to AGI.

People say it all the time. There is a popular contingent which says that we will hit AGI very soon. Lead author came from Open AI.

https://ai-2027.com/

Being able to manually write out hundreds of steps of the Towers of Hanoi problem is not a requirement for AGI, in much the same way that being able to manually multiply 50 digit numbers is not a requirement to be a successful mathematician.

i gave it a 4 step research task with branching subtasks. told it upfront what the goal was. halfway through it forgot why it was doing step 2. asked it to summarise progress so far and it hallucinated a step i never mentioned. restarted from scratch with memory enabled. same thing. no state carryover. no grounding. if you don’t constantly babysit the thread and refeed everything, it breaks. persistent memory is surface-level. no real continuity. just isolated task runner. autonomy without continuity is not autonomy

Sounds pretty useless

Re context and overthinking:

> One thing I noticed from early access: if you don’t give it enough context, it does tend to overthink.

I agree with this – that being said, I find that simply asking at the end of a prompt "Do you need any clarifications before you continue?" does a pretty good job at helping AI pin down details as well.

The first thing I asked was along the lines of "Find me an implementation of X that does not depend on framework Y, because it's not maintained". o3 thought for a minute and then returns a repository that depends on Y. In its defense, 4.1 also found the same repo and commented that it "has a light dependency", which was cute, if unhelpful.

Adding a "think about whether your answer actually depends on Y" fixed it, and the response was pretty well thought out. My only gripe is the current persona seems to be tech-bro-informal. It opened with "TL;DR" and included a lot of developer slang that reads like it's trying to be cool in a way that masks overconfidence.

o3 pro seems to be good with meta-prompting. Meaning, when you ask it to create a prompt for you. In particular it seems to be more concise than o3 when doing this.

Has anybody else noticed this?

Do you have an example?

I'm trying to understand what you mean by meta promoting

Literally just asking it to write a prompt to ask itself (or maybe another LLM) to do something.

Example: You want to improve a piece of code that interprets bytecode and translates it into native 8051 assembly. You have the code, but you don't really have any ideas on how to improve it. You want the LLM to come up with ideas.

Without meta prompting, your prompt would be like this:

"Here's a piece of code that interprets bytecode and translates it into native 8051 assembly. Think of ways to improve it."

With meta prompting, your initial prompt would be like this:

"Here's a piece of code that interprets bytecode and translates it into native 8051 assembly. My goal is to improve it. Don't think about the improvements, though.

Instead, write a large language model prompt that will guide the LLM on ways of thinking about possible improvements. Incorporate as many methods as you can think of."

The o3 would then come back with a prompt like this:

----------

Here's a piece of code that interprets bytecode and translates it into native 8051 assembly. I'd like you to think of some ways to improve it. Here are some guidelines about what you should and shouldn't do:

- Describe different models of optimization (e.g., peephole, mid-level IR transformation, architecture-aware instruction packing) that might apply to this code.

- Provide brief explanations behind each improvement idea, optionally citing known compiler or assembler optimization strategies.

- Use critical code analysis strategies such as abstraction refactoring, loop unrolling evaluation, and inline expansion assessment.

- Suggest external tools, static analysis techniques, or benchmarks that would support an empirical review of the code’s performance.

- Draft a structured list of investigative questions I should ask to uncover hidden inefficiencies or architecture mismatches.

- Consider ways to minimize register swaps and optimize instruction selection for the 8051 architecture.

- Try breaking your ideas into perspectives—a performance-focused one, a maintenance-focused one, and a correctness-focused one.

- Emphasize reasoning paths: “Consider factors like X, contrast options A and B…”

- Do not directly suggest code changes—instead, construct a high-quality LLM prompt I can run that will guide another model into doing this with rich and varied insights.

- Step into the shoes of different roles: a compiler designer, a security auditor, and a systems programmer. Think from each of their perspectives.

- Don’t just list ideas—group them by impact level and feasibility, and reflect on trade-offs.

- Don’t rewrite the entire architecture. Focus on micro-optimizations and structural improvements that retain the current functional design.

- Evaluate whether parts of the bytecode can be cached or memoized to avoid reprocessing.

- Analyze for common performance bottlenecks typical in interpreters, such as inefficient branching or redundant memory access.

- Avoid superficial ideas like "add comments" or "modernize syntax" unless critically justified.

----------

As you can see, the meta-prompt is essentially an instruction to "compile" a shorter prompt into something much larger and more detailed - which may be wrong, but if the meta-prompt basically encodes well-known methodology (like above), it's hard for it to go wrong.

(Yes, I did use an LLM to generate the list above - I checked each bullet point by hand just to make sure they weren't nonsensical.)

Xcode and ChatGPT.app are in severe need of better ways to run multiple queries in parallel, operating on the same project (Xcode or whatever other dev tools)

In a world where LLMs can write code fairly well and make use of browsers, I'm not sure if MCP is truly the "USB-C port of AI applications."

The more MCP tools I expose to the LLM, the harder it becomes for the LLM to get the job done. Instead, a single run_python tool works much better and faster. This is especially true for the reasoning models where context matters more.

I think o3-pro is just o3-very-high. And for my taste it is a bit too high.

>I wrote up all my thoughts, got ratio’ed by @sama

I have no idea what this verb means.

  When a reply to a tweet gets more likes than the tweet it was replying to, usually indicating the unpopularity or stupidity of the original tweet

Damn you got 12 likes and his reply got 271 likes? He totally ratioed you bro

https://www.urbandictionary.com/define.php?term=Ratioed

If only there was a way to learn the meaning of words....

Let me chatgpt that for you:

When someone “gets ratioed,” it means their post has more negative feedback than positive engagement. The number of comments or replies outweighs the number of likes or retweets, indicating the content is controversial.

When someone says they "got ratioed by <someone>", it usually means that the reply or response from that person received significantly more engagement (likes, retweets, etc.) than the original post.

It very often happens when a popular account disagrees with your take. When someone with a big following replies to your post, their audience quickly sees it, and if their response is witty, harsh, or widely agreed with, it can snowball into a ratio very fast. Their followers will usually like and boost their reply, sometimes swarming your original post with disagreement or mockery.

seems like the AI model is plateau isn't???

its just undercutting Gemini by a close margin in terms of capabilities

We learn that good reasoning models lack social skills.

So kinda like autists (in a good way).

its fast AF bro!

The directing is great.
