Can the Apple M4 Max 48GB run GTE-ModernColBERT-v1?

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

GTE-ModernColBERT-v1 on the Apple M4 Max 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 632k 1245.9-1502.4 t/s ~22.8-27.5 (slow)
Q8 yes 634k 2491.8-3004.8 t/s ~45.6-55 (slow)
Q4 yes 635k 4449.7-5365.8 t/s ~81.5-98.3 (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 GTE-ModernColBERT-v1?โ–ถ

Yes. At Q4 it generates ~4449.7-5365.8 tok/s and fits up to 635k context; beyond that it spills to SSD swap and slows to ~81.5-98.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 635k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
