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
- NVFP4 weights
- Throughput
- ~5,918 tok/s
- many requests batched
- Price
- $0.14–1.22 /M tok
- busy → light use
- On your own machine
- RTX 5090 32GB (NVFP4, ~80 tok/s single-stream)
- single consumer GPU or Mac
Assumptions (5)
- NVFP4 weights (27.8B params) + 25% KV-cache headroom ≈ 20 GB
- 1× B200 180GB at $5.98–$14.24/GPU-hour on-demand (2026-09-24)
- ~5,918 output tok/s aggregate at batch 169 (bandwidth-bound)
- Blended 3:1 input:output; prefill ~38,242 tok/s
- Low = 75% utilization at the low GPU price; high = 20% at the high price
