Research

The science behind the benchmarks

These benchmarks are based on research demonstrating that fusing sequential fitness evaluations into single GPU compute shader dispatches achieves 159× throughput over PyTorch's per-step dispatch. A native Metal baseline confirms Chrome's browser overhead is only 48% — yet WebGPU still outperforms PyTorch MPS running natively.
