QuantFits?Max contextSpeedBeyond context
FP16 yes 735k 15.7-18.9 t/s ~0.4-0.5 (slow)
Q8 yes 801k 31.4-37.9 t/s ~0.8-0.9 (slow)
Q4 yes 830k 56.1-67.6 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 Apple M3 Max 128GB run Mamba2-Hybrid?▶

Yes. At Q4 it generates ~56.1-67.6 tok/s and fits up to 830k context; beyond that it spills to SSD swap and slows to ~1.4-1.7 tok/s.

How much context fits?▶

At Q4, up to about 830k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
