Generated throughput, including reasoning tokens — so a thinking model's line does not collapse; the table ranks on visible tokens · one cell per model, showing its best-covered provider · models with at least 4 samples in the window first, fastest of those at the top · shared vertical scale, 0 to 108 tok/s (99th percentile) · dashed rule is the model's own mean · 1 cell carry fewer than 4 samples
