Yes. the earlier models are esp bad at even simple math / simple logic for instance with this simple puzzle:

> I live in an apartment building with a broken elevator.
> 
> If I enter it and push the button for a floor with an even number, it goes to that floor but doesn’t open the door and then goes back to where I started.
> 
> So if I enter the elevator on floor 1 and push the floor 4 button.. and when it stops, I get out and climb three additional flights by foot… what floor do I end up on ?

best answer: floor 4

All my Discourse AI personas based on gpt4o get this right , (except the one with only local / RAG context .. because no relevant context.. )

but I just ran this by gpt 3.5 in the openAI gui, and it replied ..

> **Let’s break it down step by step:**
> 
> 1. You enter the elevator on floor 1 and press the button for floor 4.
> 2. The elevator goes up to floor 4 but doesn’t open the door, then it goes back to where you started (floor 1).
> 3. You get out of the elevator on floor 4 and climb three additional flights of stairs by foot.
> 
> Since you started on floor 1 and climbed three additional flights of stairs, you would end up on floor 7.

and oddly.. in the Gemini 1.5 Pro in browser GUI … ask about towel drying..

> … with 10 towels, each towel has more surface area exposed to the sun and air, allowing for faster drying. With 15 towels, some towels might be bunched together or overlapping, reducing the effective drying surface area per towel.
> 
> Therefore, it won’t simply take 50% more time (1.5 times 30 minutes) to dry 50% more towels. It likely will take more time, but not necessarily an exact 1.5 fold increase.
> 
> **Estimation:**
> 
> A reasonable estimate could be around 45 minutes to 1 hour. This considers the reduced drying efficiency with more towels but avoids assuming a perfectly linear relationship between drying time and towel count.

.. Scary stuff ! : )
