Memory: 3x DGX Spark (GB10) has 384 GB. GLM-5.3 Flash weights are about 195.8 GB at Q4_K_M (320B 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.
