FP16 yes 228k 6.9-8.3 t/s ~0.1-0.2 (slow)
Q8 yes 331k 13.8-16.6 t/s ~0.3-0.3 (slow)
Q4 yes 376k 24.6-29.6 t/s ~0.4-0.5 (slow)

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

Can the Apple M4 Max 128GB run Qwen Image?โ–ถ

Yes. At Q4 it generates ~24.6-29.6 tok/s and fits up to 376k context; beyond that it spills to SSD swap and slows to ~0.4-0.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 376k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
