Can the NVIDIA B200 run OPT-IML (175B)?
Yes — here's how fast and up to what context, with real measured numbers.
OPT-IML (175B) on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | no | — | — | — |
| Q8 | yes | 267 | 33.4-39.8 t/s | ~0.2-0.2 (slow) |
| Q4 | yes | 147k | 59.6-71 t/s | ~0.3-0.4 (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-IML (175B)?▶
Yes. At Q4 it generates ~59.6-71 tok/s and fits up to 147k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.3-0.4 tok/s.
How much context fits?▶
At Q4, up to about 147k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
