How we got this number
Each generated token reads the whole model from memory once: 8.1 GB. The NVIDIA DGX Spark (128GB) moves 273 GB/s, so the ceiling is 34 tokens/sec. Real machines reach a fraction of that ceiling; we use 70%, an assumption until we get measured runs for this kind of machine. Send us your real numbers and we'll replace the estimate.
