single consumer GPU or Mac
Assumptions (5)
  • BF16 weights (1.28B params) + 25% KV-cache headroom ≈ 3 GB
  • 1× H200 141GB at $3.59–$7.91/GPU-hour on-demand (2026-09-24)
  • ~18,059 output tok/s aggregate at batch 256 (bandwidth-bound)
  • Blended 3:1 input:output; prefill ~182,540 tok/s
  • Low = 75% utilization at the low GPU price; high = 20% at the high price
