How we estimate →What it would cost to run these open weights yourself on rented GPUs. No API sells this model, so this is its price on the chart.
- Hardware
- 1× B200 180GB
- FP8 weights
- Throughput
- ~2,343 tok/s
- many requests batched
- Price
- $0.35–3.09 /M tok
- busy → light use
- On your own machine
- Mac Studio M5 Max 128GB (int4, ~12 tok/s single-stream)
- single consumer GPU or Mac
Assumptions (5)
- FP8 weights (70B params) + 40% KV-cache headroom ≈ 98 GB
- 1× B200 180GB at $5.98–$14.24/GPU-hour on-demand (2026-09-24)
- ~2,343 output tok/s aggregate at batch 67 (bandwidth-bound)
- Blended 3:1 input:output; prefill ~15,188 tok/s
- Low = 75% utilization at the low GPU price; high = 20% at the high price
