The math proof on the front page seems to be wrong. It gets the correct answer, of course, but the reasoning is nonsensical.

It incorrectly says to pick one point A and draw a great circle through it and the “antipodal point” A’ (which is then forgotten about). Then continues and says the great circle “contains A” and one hemisphere must have at least two points. It then asserts that 1+2=4 (!) and therefore 4 points lie on a hemisphere.

Instead, the question should have said to pick two points A and B, and construct a great circle through those. Then continue as before and 2+2=4, QED.

(This is not just a notation thing: A’ can’t, in general be one of the given points since there’s no guarantee that any two points will be antipodal)

The test time computation with Compound AI marks a significant breakthrough. It seems that model diversity fosters greater innovation and could potentially offer a more comprehensive solution compared to the more narrowly focused O1 approach. Let’s see how this unfolds.

Just failed the Rs in strawberry test.

It would be nice when they give you the fancy, come join us marketing bs that they tell you it is a paid service. No intention of paying for AI that doesn't make me money. Sheesh
