Can the NVIDIA H200 run LUXIA-21.4B-Alignment?

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

LUXIA-21.4B-Alignment on the NVIDIA H200

QuantFits?Max contextSpeedBeyond context
FP16 yes 326k 81.9-97.6 t/s ~0.7-0.8 (slow)
Q8 yes 407k 163.7-195.1 t/s ~1.4-1.6 (slow)
Q4 yes 443k 292.4-348.5 t/s ~2.4-2.9 (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 H200 run LUXIA-21.4B-Alignment?โ–ถ

Yes. At Q4 it generates ~292.4-348.5 tok/s and fits up to 443k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2.4-2.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 443k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
