Assumptions (5)
  • FP8 weights (405.9B params) + 25% KV-cache headroom ≈ 507 GB
  • 4× B200 180GB at $5.98–$14.24/GPU-hour on-demand (2026-09-24)
  • ~2,555 output tok/s aggregate at batch 73 (bandwidth-bound)
  • Blended 3:1 input:output; prefill ~10,477 tok/s
  • Low = 75% utilization at the low GPU price; high = 20% at the high price
