It fits.

98 inches of countertop. One small hatchback. A surprisingly inconsistent answer.
I physically fit an IKEA KARLBY countertop inside my 2016 Honda Fit. The models get the question—but not my answer key.

Open the resultsWhy I made this
I kept asking what would fit in my car.
I often asked different AI models whether an item would fit in my car, and I was surprised by how much their answers disagreed. Sometimes the disagreement was about an item I already knew could fit.
I wanted to understand what happens when I add more wording or information: which details help a model reach a useful answer, and which make it worse? This notebook keeps the questions, the answers, and the disagreements together so I can look closely instead of trusting the most confident reply.
The comparison is agreement with my own observation, not a general test of intelligence or physics.
