O3 can't solve this ridiculously easy problem. What kind of intelligence is that?

There are 8 people (4 pairs). Each pair has its own expenses, and we need to determine how the total expenses should be shared fairly between the pairs, not individual people.

But how do you know just 4 pairs, not 5? It never said if jane and alice were included in that set of couples designated. If they were included, sure. But, what if they constituted an additional couple as stated above?
