Can the Apple M3 Max 36GB run Stable Diffusion 3.5 Large?

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

Stable Diffusion 3.5 Large on the Apple M3 Max 36GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 112k 12.6-15.2 t/s ~0.4-0.5 (slow)
Q8 yes 174k 25.2-30.4 t/s ~0.8-1 (slow)
Q4 yes 201k 45-54.2 t/s ~1.5-1.8 (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 M3 Max 36GB run Stable Diffusion 3.5 Large?โ–ถ

Yes. At Q4 it generates ~45-54.2 tok/s and fits up to 201k context; beyond that it spills to SSD swap and slows to ~1.5-1.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 201k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
