Memory: Apple M4 Pro has 48 GB. Flint 40B-A2.5B weights are about 24.3 GB at Q4_K_M (39.8B params × 4.89 bits ÷ 8, before context/KV cache). Arithmetic, not a measurement; long contexts need more. Check other quants in the VRAM calculator.

Speeds are decode (generation) tokens/sec as reported by each source; quant, engine and context differ, so small gaps are noise.
