Stable Diffusion 3.5 Medium on the Apple M4 Max 36GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 395k 74.3-89.5 t/s ~1.4-1.6 (slow)
Q8 yes 433k 148.5-179.1 t/s ~2.7-3.3 (slow)
Q4 yes 450k 265.2-319.8 t/s ~4.9-5.9 (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 36GB run Stable Diffusion 3.5 Medium?โ–ถ

Yes. At Q4 it generates ~265.2-319.8 tok/s and fits up to 450k context; beyond that it spills to SSD swap and slows to ~4.9-5.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 450k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
