ESM1-670M (UR50/S) on the Apple M3 Max 36GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 451k 152.4-183.8 t/s ~5.1-6.1 (slow)
Q8 yes 461k 304.8-367.6 t/s ~10.2-12.3 (slow)
Q4 yes 466k 544.4-656.4 t/s ~18.1-21.9 (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 M3 Max 36GB run ESM1-670M (UR50/S)?โ–ถ

Yes. At Q4 it generates ~544.4-656.4 tok/s and fits up to 466k context; beyond that it spills to SSD swap and slows to ~18.1-21.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 466k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
