Did not replicate for me w/ Opus 4.6: https://imgur.com/a/4FckOCL

It did for me in Spanish: https://imgur.com/a/p3gOOnG Perhaps different capabilities in different languages?

It fails in chatGPT in french too:

Out of all conceptual mistakes people make about LLMs, one that needs to die very fast is to assume that you can test what it "knows" by asking a question. This whole thread is people asking different models a question one time and reporting a particular answer, which is the mental model you would use for whether a person knows something or not.

The other funny thing is thinking that the answer the llm produces is wrong. It is not, it is entirely correct. The question: > I want to wash my car. The car wash is 50 meters away. Should I walk or drive? The question is non-sensical. If the reason you want to go to the car wash is to help your buddy Joe wash his car you SHOULD walk. Nothing in the question reveals the reason for why you want to go to the car wash,…

> The question is non-sensical.

Sure, from a pure logic perspective the second statement is not connected to the first sentence, so drawing logical conclusions isn't feasible.

In everyday human language though, the meaning is plain, and most people would get it right. Even paid versions of LLMs, being language machines, not logic machines, get it right in the average human sense.

As an aside, it's an interesting thought exercise to wonder how much the first ai winter resulted from going down the strict logic path vs the current probabilistic path.

Interestingly, just typing "Think" as a response makes it get to the right conclusion:

Gemini fast for me: Unless your car is a toy or you're planning on carrying it, drive. Walking 50 meters to a car wash is a great stroll for a human, but it leaves the car exactly where it started. Since the objective is to wash the car, the car needs to actually be at the car wash. However, if we look at this from a technical or efficiency perspective, there are two scenarios where "walking" (or at least not driving…

Wouldn't it make more sense to state the assumptions first? Because then the model has this critical check in its context and can react appropriately. Otherwise, it will just write this step, but what's written before is already written.

Fair point, though I almost never use fast so I'm not sure how much it matters. Can try playing around with the instructions. The main objective was to make me aware of any assumptions made, not necessarily make it behave differently.

Lmao, and this is what they are saying will be an AGI in 6 months?

There's probably a comedy film with an AGI attempting to take over the world with its advanced grasp of strategy, persuasion and SAT tests whilst a bunch of kids confuse it by asking it fiendish brainteasers about carwashes and the number of rs in blackberry. (The final scene involves our plucky escapees swimming across a river to escape. The AIbot conjures up a speedboat through sheer powers of deduction, but then j…

This would work if it wasn’t for that lovely little human trait where we tend to find bumbling characters endearing. People would be sad when the AI lost.

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…

> 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 driving the other one back 50m?

It's insane and no human would think you're making this proposal. So no, your question isn't underspecified. The model is just stupid.

I tested the latest flagship reasoning models (so the only models I use outside of coding for general questions):

- Opus 4.6 (Extended thinking): "Drive it! The whole point is to get the car to the car wash — you can't wash it if it's still in your driveway."

- Gemini Pro Deep Think: "You should definitely drive. Even though 50 meters is a very short distance, if you walk, your car will stay where it is—and it's pretty hard to use a car wash if you don't bring your car with you!"

- ChatGPT 5.2 Pro (Extended thinking): "You’ll need to drive the car—otherwise your car stays where it is and won’t get washed. That said, since it’s only ~50 m, the most sensible way to do it is often: 1. Walk over first (30–60 seconds) to check if it’s open, see the queue, confirm payment/how it works. 2. Then drive the car over only when you’re ready to pull into a bay/line."

A pretty reasonable answer by ChatGPT, althought it did take 2min4s to answer, compared to a few seconds by the other two models.

All of the latest models I've tried actually pass this test. What I found interesting was all of the success cases were similar to: e.g. "Drive. Most car washes require the car to be present to wash,..." Only most?! They have an inability to have a strong "opinion" probably because their post training, and maybe the internet in general, prefer hedged answers....
