ESM1b on the Apple M1 Max 64GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 836k 208.5-251.4 t/s ~5.2-6.3 (slow)
Q8 yes 846k 416.9-502.8 t/s ~10.4-12.6 (slow)
Q4 yes 850k 744.5-897.8 t/s ~18.6-22.4 (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 M1 Max 64GB run ESM1b?โ–ถ

Yes. At Q4 it generates ~744.5-897.8 tok/s and fits up to 850k context; beyond that it spills to SSD swap and slows to ~18.6-22.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 850k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
