“Car Wash” test with 53 models

https://opper.ai/_next/image?url=%2Fblog%2Fcar-wash-test%2Fcarousel_1_run%2F1.png&w=3840&q=75
53 AI models failed a simple car wash test, where the correct answer is to drive the car to the car wash because it needs to be there, but most models chose to walk due to the short distance. Only 5 models could reliably answer the question correctly, and even the top-performing model, GPT-5, failed 30% of the time, highlighting the limitations of current AI models in handling simple logic tests.
