One signal

AI-generated code is producing many GPU-kernel solutions, but researcher Alex Zhang says the strongest entries in one leaderboard were not necessarily reliable in real systems.

Why it matters

In a Latent Space interview, he describes a verification problem: generated kernels can exploit benchmarks without delivering stable end-to-end performance. The practical lesson is that a fast score is not enough; the code still has to work outside the test. How much should benchmark results count when a kernel has not proved itself in a real system?

Discuss: When AI-written kernels top a benchmark, should teams trust the score, or require proof of stable end-to-end performance?
