FAQ

Can the NVIDIA GeForce RTX 4090 run Magistral Small 1.1?โ–ถ

Yes. At Q4 it generates ~54.8-65.3 tok/s and fits up to 27k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2.2-2.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 27k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
