Assumptions (5)
  • BF16 weights (20.9B params) + 25% KV-cache headroom ≈ 52 GB
  • 1× B200 180GB at $5.98–$14.24/GPU-hour on-demand (2026-09-24)
  • ~5,602 output tok/s aggregate at batch 160 (bandwidth-bound)
  • Blended 3:1 input:output; prefill ~25,434 tok/s
  • Low = 75% utilization at the low GPU price; high = 20% at the high price
