## AI overview

The article tests AI agents generating CUDA kernels on an NVIDIA DGX Spark and emphasizes that trustworthy benchmarking is harder than producing optimized code. Its experiments report a correct matrix multiplication kernel that ran 1.57x faster than torch.compile, while showing how flawed baselines, timing, and correctness checks can exaggerate speedups. It offers practical guidance for deciding when custom AI-generated GPU kernels are useful.

## Source excerpt

AI agents can now write CUDA kernels that outperform PyTorch--but proving those speedups are real is the harder problem. I put them to the test on an NVIDIA DGX Spark and found that benchmark design matters just as much as the code.
