Assumptions (5)
  • FP8 weights (671B params, 37B active per token) + 25% KV-cache headroom ≈ 839 GB
  • 8× B200 180GB at $5.98–$14.24/GPU-hour on-demand (2026-09-24)
  • ~21,907 output tok/s aggregate at batch 627 (bandwidth-bound); MoE compute scales with active params
  • Blended 3:1 input:output; prefill ~229,865 tok/s
  • Low = 75% utilization at the low GPU price; high = 20% at the high price
