Can the Apple M3 Max 128GB run s1?

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

s1 on the Apple M3 Max 128GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 190k 4.3-5.1 t/s ~0.1-0.1 (slow)
Q8 yes 312k 8.5-10.3 t/s ~0.2-0.3 (slow)
Q4 yes 365k 15.2-18.3 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.

FAQ

Can the Apple M3 Max 128GB run s1?โ–ถ

Yes. At Q4 it generates ~15.2-18.3 tok/s and fits up to 365k 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 365k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
