How we estimate →What it would cost to run these open weights yourself on rented GPUs, compared with the API price above.
- Hardware
- 8× B200 180GB
- FP8 weights
- Throughput
- ~4,098 tok/s
- many requests batched
- Price
- $2.27–20.3 /M tok
- busy → light use
- On your own machine
- Mac Studio M5 Ultra 512GB (int4, ~2 tok/s single-stream)
- single consumer GPU or Mac
Assumptions (5)
- FP8 weights (763B params) + 40% KV-cache headroom ≈ 1068 GB
- 8× B200 180GB at $5.98–$14.24/GPU-hour on-demand (2026-09-24)
- ~4,098 output tok/s aggregate at batch 117 (bandwidth-bound)
- Blended 3:1 input:output; prefill ~11,147 tok/s
- Low = 75% utilization at the low GPU price; high = 20% at the high price
