Can the Apple M4 Max 36GB run Stable Diffusion 3 Medium?

Yes โ€” here's how fast and up to what context, with real measured numbers.

Stable Diffusion 3 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 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.
