QuantFits?Max contextSpeedBeyond context
FP16 yes 459k 251.1-302.7 t/s ~8.4-10.1 (slow)
Q8 yes 465k 502.1-605.5 t/s ~16.7-20.2 (slow)
Q4 yes 468k 896.6-1081.2 t/s ~29.9-36 (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 BART-large?โ–ถ

Yes. At Q4 it generates ~896.6-1081.2 tok/s and fits up to 468k context; beyond that it spills to SSD swap and slows to ~29.9-36 tok/s.

How much context fits?โ–ถ

At Q4, up to about 468k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
