LUXIA-21.4B-Alignment on the NVIDIA RTX PRO 6000 Blackwell

QuantFits?Max contextSpeedBeyond context
FP16 yes 168k 30.6-36.4 t/s ~0.7-0.8 (slow)
Q8 yes 250k 61.1-72.9 t/s ~1.4-1.6 (slow)
Q4 yes 285k 109.2-130.1 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 RTX PRO 6000 Blackwell run LUXIA-21.4B-Alignment?โ–ถ

Yes. At Q4 it generates ~109.2-130.1 tok/s and fits up to 285k 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 285k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
