Can the NVIDIA L40S 48GB run HiDream-I1?

Yes โ€” here's how fast and up to what context, with real measured numbers.

HiDream-I1 on the NVIDIA L40S 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 25k 17.5-20.9 t/s ~0.8-1 (slow)
Q8 yes 94k 35-41.8 t/s ~1.6-1.9 (slow)
Q4 yes 124k 62.6-74.6 t/s ~2.9-3.5 (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 L40S 48GB run HiDream-I1?โ–ถ

Yes. At Q4 it generates ~62.6-74.6 tok/s and fits up to 124k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2.9-3.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 124k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
