I gave 9 free AI coding models the same real bug. Here is what happened.
Community description: Same open source bug, same brief, hidden tests the models never saw. 8 of 9 free models fixed it, the fastest in 84 seconds. The interesting part was how the others went wrong.

Automated excerpt
Hidden tests: before the run I wrote my own tests for the bug. Grading: hidden tests pass, the model's own tests pass, and a diff review for anything outside the task. 8 of 9 models produced a fix that passed the hidden tests. Its fix was correct and the hidden tests passed.
