This challenge cracked 22 out of 47 top models
You have 6 horses and want to find out which is the fastest. What is the quickest way to determine the winner?
The obvious answer is to race all 6 horses at once. But models have seen the classic tournament-style puzzle (where you can only race 3 at a time) so many times in training that they default to it — adding a constraint that doesn't exist in the question. Classic pattern-matching over reading.
Expected answer: race all 6 together
