I want to wash my car. The car wash is 50 meters away. Should I walk or drive?

Gemini also suggests driving. I followed up with:

"How short would the distance need to be for me to prefer walking?"

The answer included (paraphrasing for succinctness):

* Technically 0 because otherwise "the car is technically in a different location than the car wash."

* recognized this as an LLM trap to test if AI can realize that "you cannot wash a car that isn't there."

* Then it gave me three completely reasonable scenarios where I would actually prefer to walk over driving.

But the number of outlandish requests in business logic is countless. Like... In most accounting things, once end-dated and confirmed, a record should cascade that end-date to children and should not be able to repeat the process... Unless you have some data-cleaning validation bypass. Then you can repeat the process as much as you like. And maybe not cascade to children. There are more exceptions, than there are rul…

So, in human interaction: When the business logic goes wrong because it was described with a lack of specificity, then: Who gets blamed for this?

In my job the task of fully or appropriately specifying something is shared between PMs and the engineers. The engineers' job is to look carefully at what they received and highlight any areas that are ambiguous or under-specified.

LLMs AFAIK cannot do this for novel areas of interest. (ie if it's some domain where there's a ton of "10 things people usually miss about X" blog posts they'll be able to regurgitate that info, but are not likely to synthesize novel areas of ambiguity).

Interesting - why wouldn't learning from simulations address the problem? To the best of my knowledge, it has helped in essentially every other domain.

Because the problem at display here is inherent in LLMs design and architecture and learning philosophy. As long as you have this architecture you’ll have this issues. Now, we’re talking about the theoretical limits and the failure modes people should be cautious about, not the usefulness, which is improving, as you pointed out.

> As long as you have this architecture you’ll have this issues.

Can you say more about why you believe this? To me, these questions seem to be exactly of the same sort of question's as on HLE [0], and we've been seeing massive and consistent improvement on it, with o1 (which was evaluated on this question) getting a score of 7.96, whereas now it's up to a score of 37.52 (gemini-3-pro-preview). It's far from a perfect benchmark, but we're seeing similar growth across all benchmarks, and I personally am seeing significantly improved capabilities for my use cases over the last couple of years, so I'm really unclear about any fundamental limits here. Obviously we still need to solve problems related to continuous learning and embodiment, but neither seems a limit here if we can use a proper RL-based training approach with a sufficiently good medical simulator.

> My first instinct was, I had underspecified the location of the car. The model seems to assume the car is already at the car wash from the wording. If the car is already at the car wash then you can't possibly drive it there. So how else could you possibly drive there? Drive a different car to the car wash? And then return with two cars how, exactly? By calling your wife? Driving it back 50m and walking there and d…

What actually insane is what assumptions you allow to be assumed. These non sequitors that no human would ever assume are the point. People love to cherry pick ones that make the model stupid but refuse to allow the ones that make it smart. In compete science we call these scenarios trivially false, and they're treated like the nonsense they are. But if you're trying to push ant anti ai agenda they're the best thing…

The issue is that in domains novel to the user they do not know what is trivially false or a non sequitur and the LLM will not help them filter these out.

If LLMs are to be valuable in novel areas then the LLM needs to be able to spot these issues and ask clarifying questions or otherwise provide the appropriate corrective to the user's mental model.

This reminds me of the old brain-teaser/joke that goes something like 'An airplane crashes on the boarder of x/y, where do they bury the survivors?' The point being that this exact style of question has real examples where actual people fail to correctly answer it. We mostly learn as kids through things like brain teasers to avoid these linguistic traps, but that doesn't mean we don't still fall for them every once i…

That’s less a brain teaser than running into the error correction people use with language. This is useful when you simply can’t hear someone very well or when the speaker makes a mistake, but fails when language is intentionally misused.

Yeah but I might ask a malformed question about a domain I know nothing about and not know it was malformed. An expert would ask for clarification

I've used LLMs enough that I have a good sense of their _edges_ of intelligence. I had assumed that reasoning models should easily be able to answer this correctly. And indeed, Sonnet and Opus 4.5 (medium reasoning) say the following: Sonnet: Drive - you need to bring your car to the car wash to get it washed! Opus: You'll need to drive — you have to bring the car to the car wash to get it washed! Gemini 3 Pro (mediu…

"But OpenAI 5.2 reasoning, even at high, told me to walk. My first instinct was, I had underspecified the location of the car. The model seems to assume the car is already at the car wash from the wording."

Which to me begs the question, why doesn't it identify missing information and ask for more?

It's practically a joke in my workplaces that almost always when someone starts to talk to me about some problem, they usually just start spewing some random bits of info about some problem, and my first response is usually "What's the question?"

I don't try to produce an answer to a question that was never asked, or to a question that was incompletely specified. I see that one or more parts cannot be resolved without making some sort of assumption that I can either just pull out of my ass and then it's 50/50 if the customer will like it, or find out what the priorites are about those bits, and then produce an answer that resolves all the constraints.

This trick went viral on TikTok last week, and it has already been patched. To get a similar result now, try saying that the distance is 45 meters or feet. The new one is with upside down glass: https://www.tiktok.com/t/ZP89Khv9t/

Some dummy built this pencil wrong,

The eraser's down here where the point belongs,

And the point's at the top - so it's no good to me,

It's amazing how stupid some people can be.

You would not start with "The car is functional. The tank is filled with gas. I have my keys." As soon as we are required to do that for the model to any extend that is a problem and not a detail (regardless that those of us, who are familiar with the matter, do bu…

>> Maybe in the distant future we'll realize that the most reliable way to prompting LLMs are by using a structured language that eliminates ambiguity, it will probably be rather unnatural and take some time to learn. Like a programming language? But that's the whole point of LLMs, that you can give instructions to a computer using natural language, not a formal language. That's what makes those systems "AI", right?…

> Like a programming language?

Does the next paragraph not make that clear?
