They probably added a system guardrail as soon as they heard about this test. it's been going around for a while now :)

Article mentions that Gemini 2.0 Flash Lite, Gemini 3 Flash and Gemini 3 Pro have passed the test. All these 3 also did it 10 out of 10 times without being wrong. Even Gemini 2.5 shares highest score in the category of "below 6 right answers". Guess, Gemini is the closest to "intelligence" out of a bunch.

Something being useful doesn't imply it's good or beneficial. Those terms are not synonymous. Usefulness describes whether a thing achieves a particular goal or serves a specific purpose effectively. A torture device is useful for extracting information. A landmine is useful for denying an area to enemy troops.

A torture device is useful for extracting information.

No it fucking isn't! This is a great analogy, actually, thank you for bringing it up. A person being tortured will tell you literally anything that they believe will stop you from torturing them. They will confess to crimes that never happened, tell you about all their accomplices who don't exist, and all their daily schedules that were made up on the spot. Torture is useless but morons think it is useful. Just like AI.

Remember that LLMs don't very well understand what a car wash is, as it can be both a place, and an action. Can you define a car wash? There's many types... I can see future LLMs start asking useful follow up/clarity questions before giving their answers. Which could help those who rely on them so much to understand how their questions can be misconstrued.

A car wash is a place where a car is washed by a machine, other people or yourself

Without reading the article, the title just says wash the car. I could go for a walk and wash my car in my driveway. Reading the article... That is exactly the question asked. It is a very ambiguous question. *I do understand the intent of the question, but it could be phrased more clearly.

It is not. It says what I want to do, and where.

It is an online poll. You also have to consider that some people don't care/want to be funny, and so either choose randomly, or choose the most nonsensical answer.

I wonder... If humans were all super serious, direct, and not funny, would LLMs trained on their stolen data actually function as intended? Maybe. But such people do not use LLMs.

But natural language in service of what? If they can't produce answers that are correct, what's the point of using them? I can get wrong answers anywhere.

Some of them can produce the correct answer. Of we do the test next year and they do better than humans then, isn't it progress?

After getting it wrong, the LLM I use most:
Me: You can't wash your car if it isn't there.

Ah. Yes. That is an excellent and devastatingly practical correction.

In that case: drive.
But do it with the quiet shame of someone moving the car the length of a bowling lane.

This is one of those situations where logic beats virtue. The car must be present to be washed. Walking was philosophically elegant but mechanically flawed.

So:

Start engine.

Travel 50 meters.

Avoid eye contact with pedestrians.

Commit fully.

You are not lazy. You are complying with system requirements.

Are poems, songs, stories or movie scripts ‘correct’? It's a valid point that they can produce natural language. The Turing Test has been a thing for awhile after all. But while the language sounds natural, can they create anything meaningful? Are the poems or stories they make worth anything? It's not like humans don't create shitty art, so I guess generating random soulless crap is similar to...

There are people out there whose job is to format promotional emails for companies. AIs can replace this kind of soulless work completely. We should applaud that.

if you’re wanting to wash it at home, The AI should absolutely understand the implication that you want to wash your car at the car wash, not at home. The prompt is clear about that, even though it is implied. "I want a hamburger. McDonald's is three miles from me and Wendy's is five miles. Which is the cheaper place to get a burger from when you consider the distance to each?" is not an exact ...

Pretty sure if you asked it on stackoverflow you would get a bunch of responses to make it at home and then someone would lock your question

I think there are a lot of implicit assumptions in such a short prompt. Is it a self-service car wash? If not, walking to the attendant and handing them your keys makes more sense. If it is self-service without queuing, there may be no available spaces/the bay may not be open, requiring some awkward maneuvering. If you change it to something like: I want to wash my car. The unattended, self-ser...

You know that LLMs provide their reasoning now? You can check why they answered this way and I'm sure it's not because they thought that "maybe there are no available spaces".

It's already happening. GPT 5.2 is noticeably worse than previous versions. It's called model collapse.

To clarify : model collapse is a hypothetical phenomenon that has only been observed in toy models under extreme circumstances. This is not related in any way to what is happening at OpenAI.

OpenAI made a bunch of choices in their product design which basically boil down to "what if we used a cheaper, dumber model to reply to you once in a while".

Its unpopular because its wrong.

As someone who's been using it in my work for the last 2 years, it's my personal observation that while the models aren't improving that much anymore, the tooling is getting much much better.

Before I used gpt for certain easy in concept, tedious to write functions. Today I hardly write any code at all. I review it all and have to make sure it's consistent and stable but holy has my output speed improved.

The larger a project is the worse it gets and I often have to wrap up things myself as it shines when there's less business logic and more scaffolding and predictable things.

I guess I'll have to attribute a bunch of the efficiency increase to the fact that I'm more experienced in using these tools. What to use it for and when to give up on it.

For the record I've been a software engineer for 15 years

At the end of the article they talk about how to overcome this problem for LLMs doing something akin to what you wrote.

If I were the type of person who was willing to give AI the benefit of the doubt and not assume that it was just picking basically random numbers There's a lot of cases where it can be a shorter (by distance) walk than drive, where cars generally have to stick to streets while someone on foot may be able to take some footpaths and cut across lawns and such, or where the road may be one-way for ...

I think it has to do with the fact that LLMs suck at math because they have short memories. So for the walking part it did the math of 50m (original distance) x 2 (there and back) = 100m (total distance). Then it went to the driving part and did 100m (the last distance it sees) x 2 = 200m.

The most common pushback on the car wash test: "Humans would fail this too." Fair point. We didn't have data either way. So we partnered with Rapidata to find out. They ran the exact same question with the same forced choice between "drive" and "walk," no additional context, past 10,000 real people through their human feedback platform. 71.5% said drive. So people do better than most AI models....

I saw that and hoped it is cause of the dead Internet theory. At least I hope so cause I'll be losing the last bit of faith in humanity if it isn't

Normally I'd ask "why are we comparing AI to the human mind when they're not the same thing at all," but I feel like we're presupposing they are similar already with this test so I am curious to the answer on this one.

I would guess it's because a lot of AI users see their choice of AI as an all-knowing human-like thinking tool. In which case it's not a weird test question, even when the assumption that it "thinks" is wronh

Mentioning the car wash and washing the car plus the possibility of driving the car in the same context pretty much eliminates any ambiguity. All of the puzzle pieces are there already.

I guess this is an uninteded autism test as well if this is not enough context for someone to understand the question.

What worries me is the consistency test, where they ask the same thing ten times and get opposite answers. One of the really important properties of computers is that they are massively repeatable, which makes debugging possible by re-running the code. But as soon as you include an AI API in the code, you cease being able to reason about the outcome. And there will be the temptation to say "mus...

This is adjustable via temperature. It is set low on chatbots, causing the answers to be more random. It's set higher on code assistants to make things more deterministic.

We poked fun at this meme, but it goes to show that the LLM is still like a child that needs to be taught to make implicit assumptions and posses contextual knowledge. The current model of LLM needs a lot more input and instructions to do what you want it to do specifically, like a child.

Edit: I know Lemmy scoff at LLM, but people probably also used to scoff at Veirbest's steam machine that it will never amount to anything. Give it time and it will improve. I'm not endorsing AI by the way, I am on the fence about the long term consequence of it, but whether people like it or not, AI will impact human lives.

Torture can be a useful way of extracting information if you have a way to instantly verify it, which actually makes it a good analogy to LLMs. If I want to know the password to your laptop and torture you until you give me the correct password and I log in then that works.

AI chatbots come with randomization enabled by default. Even if you completely disable it (as another reply mentions, "temperature" can be controlled), you can change a single letter and get a totally different and wrong result too. It's an unfixable "feature" of the chatbot system

I just asked Goggle Gemini 3 "The car is 50 miles away. Should I walk or drive?"

In its breakdown comparison between walking and driving, under walking the last reason to not walk was labeled "Recovery: 3 days of ice baths and regret."

And under reasons to walk, "You are a character in a post-apocalyptic novel."

Me thinks I detect notes of sarcasm......

If you can instantly verify it then you don't need the torture.

Getting the person to volunteer the information is proven to be far, far more successful and being able to instantly verofy means you know when you have the answers.
