QuantFits?Max contextSpeedBeyond context
FP16 yes 19k 7.3-8.8 t/s ~0.1-0.2 (slow)
Q8 yes 117k 14.6-17.6 t/s ~0.3-0.3 (slow)
Q4 yes 160k 26-31.4 t/s ~0.5-0.6 (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 M4 Max 64GB run InternVL2 26B?โ–ถ

Yes. At Q4 it generates ~26-31.4 tok/s and fits up to 160k context; beyond that it spills to SSD swap and slows to ~0.5-0.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 160k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
