Zagreus 0.4B on the NVIDIA GeForce RTX 5090

QuantFits?Max contextSpeedBeyond context
FP16 yes 414k 1635.2-1948.8 t/s ~36.5-43.5 (slow)
Q8 yes 420k 3270.4-3897.6 t/s ~73-87 (slow)
Q4 yes 423k 5840-6960 t/s ~130.4-155.4 (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 GeForce RTX 5090 run Zagreus 0.4B?โ–ถ

Yes. At Q4 it generates ~5840-6960 tok/s and fits up to 423k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~130.4-155.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 423k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
