GPT-4 reasons about a lot of gotcha logic puzzles correctly any pre GPT-4 opinions should be reconsidered, that is effectively two different epochs in the history of AI effectiveness and reasoning.
> Me: Mike leaves the elevator at the 2nd floor. Jenny leaves at the 9th floor. Who left the elevator first?
> GPT-4: Mike left the elevator first, as he got off at the 2nd floor, while Jenny left at the 9th floor.
> Me: If the elevator started at the 10th floor, who would have left first?
> GPT-4: If the elevator started at the 10th floor and went downward, then Jenny would have left first, as she got off at the 9th floor, while Mike left at the 2nd floor.
> Me: How many footballs fit in a coffe-mug?
> GPT-4: A standard football (soccer ball) has a diameter of around 22 centimeters (8.65 inches), while a coffee mug is typically much smaller, with a diameter of around 8-10 centimeters (3-4 inches). Therefore, it is not possible to fit a standard football inside a coffee mug. If you were to use a mini football or a much larger mug, the number of footballs that could fit would depend on the specific sizes of the footballs and the mug.
It easily answered all of your questions and produces explanations I would expect most reasonable people to make.
