Fixed test passed
Candidate sketch
Interactive code evaluation
One green test can lie.
A generated kernel passes the fixed test. Choose the next input that exposes what it missed. The browser runs both the candidate and a reference for every choice.
Five original teaching examples. About three minutes. No model call or upload.
Case 1 of 5Caught: 0

A passing fixed input says the candidate handled that input. Shape, stride, value range, row count and aliasing each need their own checks.
Why this matters
Correctness needs a wider input regime.
These browser-run sketches use original examples, not GPU kernels. They illustrate the fixed-shape testing problem studied in Dipankar Sarkar's work on LLM-generated GPU kernels. His published corpus pairs deliberately faulty variants with correct controls and uses seeded tests across shapes and dtypes.
