  This paper investigates the problem-solving capabilities of Large Language
Models (LLMs) by evaluating their performance on stumpers, unique single-step
intuition problems that pose challenges for human solvers but are easily
verifiable. We compare the performance of four state-of-the-art LLMs
(Davinci-2, Davinci-3, GPT-3.5-Turbo, GPT-4) to human participants. Our
findings reveal that the new-generation LLMs excel in solving stumpers and
surpass human performance. However, humans exhibit superior skills in verifying
solutions to the same problems. This research enhances our understanding of
LLMs' cognitive abilities and provides insights for enhancing their
problem-solving potential across various domains.
