Can the NVIDIA DGX Spark run Ovis2.5 9B?

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

Ovis2.5 9B on the NVIDIA DGX Spark

QuantFits?Max contextSpeedBeyond context
FP16 yes 730k 11.1-13.2 t/s ~0.4-0.5 (slow)
Q8 yes 799k 22.1-26.4 t/s ~0.8-1 (slow)
Q4 yes 829k 39.5-47.1 t/s ~1.4-1.7 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.

FAQ

Can the NVIDIA DGX Spark run Ovis2.5 9B?โ–ถ

Yes. At Q4 it generates ~39.5-47.1 tok/s and fits up to 829k context; beyond that it spills to SSD swap and slows to ~1.4-1.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 829k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
