QuantFits?Max contextSpeedBeyond context
FP16 yes 575k 92.8-111.9 t/s ~1.7-2.1 (slow)
Q8 yes 606k 185.6-223.9 t/s ~3.4-4.1 (slow)
Q4 yes 619k 331.5-399.8 t/s ~6.1-7.3 (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 48GB run Infinity?โ–ถ

Yes. At Q4 it generates ~331.5-399.8 tok/s and fits up to 619k context; beyond that it spills to SSD swap and slows to ~6.1-7.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 619k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
