A longitudinal AI reasoning diagnostic that tests whether models can preserve a prompt’s logical constraint when familiar wording pushes them toward the wrong answer.

Why it surfaced

Its deceptively simple prompt asks whether someone should walk or drive a dirty car to a carwash 100 feet away. The site preserves single-shot responses across 219 English-language runs and 17 model families, alongside separate multilingual and open-weight records, making the transcripts as important as the verdicts.
