How we got this number
Each generated token reads the active part of the model from memory once: 5.8 GB. The Mac Studio M5 Ultra (256GB) moves 1228.8 GB/s, so the ceiling is 120+ tokens/sec. Real machines reach a fraction of that ceiling; we use 80%, calibrated against a measured Mac run. Send us your real numbers and we'll replace the estimate.
