Can the Apple M4 Max 48GB run GBERT-Large?

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

GBERT-Large on the Apple M4 Max 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 626k 554.1-668.2 t/s ~10.1-12.2 (slow)
Q8 yes 631k 1108.3-1336.5 t/s ~20.3-24.5 (slow)
Q4 yes 633k 1979.1-2386.6 t/s ~36.2-43.7 (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 48GB run GBERT-Large?โ–ถ

Yes. At Q4 it generates ~1979.1-2386.6 tok/s and fits up to 633k context; beyond that it spills to SSD swap and slows to ~36.2-43.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 633k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
