ESM1-670M (UR50/S) on the Apple M2 Max 32GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 396k 203.2-245.1 t/s ~5.1-6.1 (slow)
Q8 yes 406k 406.5-490.1 t/s ~10.2-12.3 (slow)
Q4 yes 411k 725.8-875.2 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 M2 Max 32GB run ESM1-670M (UR50/S)?โ–ถ

Yes. At Q4 it generates ~725.8-875.2 tok/s and fits up to 411k 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 411k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
