How we got this number
Each generated token reads the whole model from memory once: 5.3 GB. The Mac mini M4 Pro (64GB) moves 273 GB/s, so the ceiling is 52 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.
