Can the NVIDIA DGX Spark run ANITA-NEXT 20B?

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

ANITA-NEXT 20B on the NVIDIA DGX Spark

QuantFits?Max contextSpeedBeyond context
FP16 yes 281k 5-5.9 t/s ~0.2-0.2 (slow)
Q8 yes 357k 10-11.9 t/s ~0.4-0.4 (slow)
Q4 yes 391k 17.8-21.2 t/s ~0.7-0.8 (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 ANITA-NEXT 20B?โ–ถ

Yes. At Q4 it generates ~17.8-21.2 tok/s and fits up to 391k context; beyond that it spills to SSD swap and slows to ~0.7-0.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 391k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
