Can the NVIDIA B200 run OPT-125M (finetuned)?
Yes — here's how fast and up to what context, with real measured numbers.
OPT-125M (finetuned) on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2669k | 23360-27840 t/s | ~116.8-139.2 (slow) |
| Q8 | yes | 2671k | 46720-55680 t/s | ~233.6-278.4 (slow) |
| Q4 | yes | 2671k | 83428.6-99428.6 t/s | ~417.1-497.1 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.
FAQ
Can the NVIDIA B200 run OPT-125M (finetuned)?▶
Yes. At Q4 it generates ~83428.6-99428.6 tok/s and fits up to 2671k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~417.1-497.1 tok/s.
How much context fits?▶
At Q4, up to about 2671k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
