Specific model I was using was o4-mini-high which the drop-down model selector describes as "Great at coding and visual reasoning".

I'm curious how you ended up in such a conversation in the first place. Hallucinations are one thing, but I can't remember the last time when the model was saying that it actually run something somewhere that wasn't a tool use call, or that it owns a laptop, or such - except when role-playing.

I wonder if the advice on prompting models to role play isn't backfiring now, especially in conversational setting. Might even be a difference between "you are an AI assistant that's an expert programmer" vs. "you are an expert programmer" in the prompt, the latter pushing it towards "role-playing a human" region of the latent space.

(But also yeah, o3. Search access is the key to cutting down on amount of guessing the answers, and o3 is using it judiciously. It's the only model I use for "chat" when the topic requires any kind of knowledge that's niche or current, because it's the only model I see can reliably figure out when and what to search for, and do it iteratively.)

I've seen that specific kind of role-playing glitch here and there with the o[X] models from openai. The models do kinda seem to just think of themselves as being developers with their own machines.. I think it usually just doesn't come up but can easily be tilted into it.

What is really interesting is in the "thinking" section it said "I need to reassure the user..." so my intuition is that it thought it was right, but did not think I would think they were right, but if they just gave me the confidence, I would try the code and unblock myself. Maybe it thought this was the best % chance I would listen to it and so it is the correct response?

Maybe? Depends on what followed that thought process.

I've noticed this couple times with o3, too - early on, I'd catch a glimpse of something like "The user is asking X... I should reassure them that Y is correct" or such, which raised an eyebrow because I already know Y was bullshit and WTF with the whole reassuring business... but then the model would continue actually exploring the question and the final answer showed no trace of Y, or any kind of measurement. I really wish OpenAI gave us the whole thought process verbatim, as I'm kind of curious where those "thoughts" come from and what happens to them.

Not saying this to defend the models as your point is fundamentally sound, but IIRC the user-visible "thoughts" are produced by another LLM summarising the real chain-of-thought, so weird inversions of what it's "really" "thinking" may well slip in at the user-facing level — the real CoT often uses completely illegible shorthand of its own, some of which is Chinese even when the prompt is in English, but even the parts in the users' own languages can be hard-to-impossible to interpret.

To agree with your point, even with the real CoT researchers have shown that model's CoT workspace don't accurately reflect behaviour: https://www.anthropic.com/research/reasoning-models-dont-say...

Okay. And the fact that LLMs routinely make up crap that doesn't exist but sounds plausible, and the fact that this appears to be a fundamental problem with LLMs, this doesn't give you any pause on your hype train? Genuine question, how do you reconcile this?

> I really wish OpenAI gave us the whole thought process verbatim, as I'm kind of curious where those "thoughts" come from and what happens to them.

Don't see what you mean by this; there's no such thing as "thoughts" of an LLM, and if you mean the feature marketers called chain-of-thought, it's yet another instance of LLMs making shit up, so.

Simply. Because the same is the case with humans. Mostly for the same reasons.

(Are humans overhyped? Maybe?)

The LLM hype train isn't about them being more accurate or faster than what came before - it comes from them being able to understand what you mean. It's a whole new category of software - programs that can process natural language like humans would; a powerful side effect that took the world by surprise is, that making LLMs better at working with natural language implicitly turns them into general-purpose problem solvers.

"Chain-of-thought" is so 2024; current models don't need to be told to "think step by step", they're post-trained to first generate a stream of intermediary tokens not meant as "actual answer", before continuing with the "actual answer". You can call it however you like; however both research literature and vendors settled on calling it "thinking" or "reasoning". Treat them as terms of art, if that helps.

Ehh... I did ask it if it would be able to figure this out or if I should try another model :|

A friend recently had a similar interaction where ChatGPT told them that it had just sent them an email or a wetransfer with the requested file

Gotcha. Yeah, give o3 a try. If you don't want to get a sub, you can use it over the api for pennies. They do have you do this biometric registration thing that's kind of annoying if you want to use over api though.

You can get the Google pro subscription (forget what they call it) that's ordinarily $20/mo for free right now (1 month free; can cancel whenever), which gives unlimited Gemini 2.5 Pro access.

I hope you appreciate just how crazy this sentence sounds, even in an age when this is normalised.

Yep, it's surreal.

Yeah, this model didn't work it seems.

You're holding it wrong. You need to utter the right series of incantations to get some semblance of truth.

What, you used the model that was SOTA one week ago? Big mistake, that explains why.

You need to use this SOTA model that came out one day ago instead. That model definitely wasn't trained to overfit the week-old benchmarks and dismiss the naysayers. Look, a pelican!

What? You haven't verified your phone number and completed a video facial scan and passed a background check? You're NGMI.

Love this reference :)

Thank you for the tip on o3. I will switch to that and see how it goes. I do have a paid sub for ChatGPT, but from the dropdown model descriptions "Great at coding" sounded better than "Advanced reasoning". And 4 is like almost twice as much as 3.

In my current experience:

- o3 is the bestest and my go-to, but its strength comes from it combining reasoning with search - it's the one model you can count on finding things out for you instead of going off vibe and training data;

- GPT 4.5 feels the smartest, but also has tight usage limits and doesn't do search like o3 does; I use it when I need something creative done, or switch to it mid-conversation to have it reason off an already primed context;

- o4-mini / o4-mini-hard - data transformation, coding stuff that doesn't require looking things up - especially when o3 looked stuff up already, and now I just need ChatGPT to apply it into code/diagrams;

- gpt-4o - only for image generation, and begrudgingly when I run out of quota on GPT 4.5

o3 has been my default starting model for months now; most of my queries generally benefit from having a model that does autonomous reasoning+search. Agentic coding stuff, that I push to Claude Code now.

I've heard my grandma talk about Catholic saints and their powers with a not dissimilar kind of discourse.

Point being?

Unlike Catholic saints, ChatGPT models actually exhibit these properties in directly observable and measurable way. I wrote how I decide which model to use for actual tasks, not which saint to pray to.

the fact that one needs to know stuff like this and that it changes every three months seriously limits the usefulness of LLMs for me

TeMPOraL 331 days ago

I get this. On the one hand, those things I wrote down are just simple conclusions from immediate experience, not something I had to learn or feel burdened by - but on the other hand, when I look at similar lists for e.g. how to effectively use Claude Code, I recoil in horror.

There's a silver lining in this, though: none of that is any kind of deep expertise, so there's no need for up-front investment. Just start using a tool and pay attention, and you'll pick up on those things in no time.

Being in the cutting edge isn't for everyone. If you can find an island where staying updated is optional you can choose that. Imo, these islands are fast shrinking.

I’d also recommend basically always having search enabled. That’s eliminated major hallucinations for me.

lol yep, fully get that. And I mean I'm sure o4 will be great but the '-mini' variant is weaker. Some of it will come down to taste and what kind of thing you're working on too but personal preferences aside, from the heavy LLM users I talk to o3 and gemini 2.5 pro at the moment seem to be top if you're dialoging with them directly (vs using through an agent system).

All LLMs can fail this way.

It's kind of weird to see people running into this kind of issue with modern large models with all the RL and getting confused. No one starting today seems to have good intuition for them. One person I knew insisted LLMs could do structural analysis for months until he saw some completely absurd output from one. This used to be super common with small GPTs from around 2022 and so everyone just intuitively knew to watch out for it.

Literally astrology at this point. We don't understand the black box bs generating machine, but actually if you prod it this and that way according to some vague vibe, then it yields results that even if wrong are enough to fool you.

And christ, every single time there's the same retort: "ah but of course your results are shit, you must not be using gpt-4.69-o7-turbo-pro which came out this morning". Come on...

You sit at the opposite of the spectrum, refusing with all your might that there might be something useful there at all. It's all just a BS generator that nothing, nothing at all useful can come out of, right? You might think you are a staunch critic and realist that no hype can touch and you see through all of it, when in fact your are wilfully ignorant.

brahma-dev 332 days ago

Here's some BS for you.

That's an unfair mischaracterization of their position. Criticism doesn't equal rejection, and skepticism isn't the same as ignorance. Pointing out limitations, failures, or hype doesn't mean they are claiming there's nothing useful or that the entire technology is inherently worthless.

Being critical is not about denying all value—it’s about demanding evidence, accuracy, and clarity amid inflated claims. In fact, responsible critique helps improve technology by identifying where it falls short, so it can evolve into something genuinely useful and reliable.

What you're calling "willful ignorance" is, in reality, a refusal to blindly accept marketing narratives or inflated expectations. That’s not being closed-minded—that’s being discerning.

If there is something truly valuable, it will stand up to scrutiny.

> refusing with all your might that there might be something useful there at all

How does this follow from what I wrote? I addressed two very concrete points.
