QuantFits?Max contextSpeedBeyond context
FP16 yes 349k 52.8-63.7 t/s ~0.7-0.8 (slow)
Q8 yes 389k 105.6-127.4 t/s ~1.3-1.6 (slow)
Q4 yes 406k 188.6-227.5 t/s ~2.4-2.8 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.

Can the Apple M2 Ultra 64GB run Qwen-VLA?โ–ถ

Yes. At Q4 it generates ~188.6-227.5 tok/s and fits up to 406k context; beyond that it spills to SSD swap and slows to ~2.4-2.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 406k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
