QuantFits?Max contextSpeedBeyond context
FP16 yes 326k 27.7-33.4 t/s ~0.5-0.6 (slow)
Q8 yes 377k 55.4-66.8 t/s ~1-1.2 (slow)
Q4 yes 399k 99-119.3 t/s ~1.8-2.2 (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 CRYSTALCODER?โ–ถ

Yes. At Q4 it generates ~99-119.3 tok/s and fits up to 399k context; beyond that it spills to SSD swap and slows to ~1.8-2.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 399k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
