Can the Apple M4 Max 36GB run GenSLM?

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

GenSLM on the Apple M4 Max 36GB

FP16 no โ€” โ€” โ€”
Q8 yes 23k 14.9-17.9 t/s ~0.3-0.3 (slow)
Q4 yes 64k 26.5-32 t/s ~0.5-0.6 (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 GenSLM?โ–ถ

Yes. At Q4 it generates ~26.5-32 tok/s and fits up to 64k context; beyond that it spills to SSD swap and slows to ~0.5-0.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 64k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
