FP16 yes 216k 20.3-24.5 t/s ~0.5-0.6 (slow)

Q4 yes 290k 72.5-87.4 t/s ~1.8-2.2 (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 48GB run Amber?โ–ถ

Yes. At Q4 it generates ~72.5-87.4 tok/s and fits up to 290k context; beyond that it spills to SSD swap and slows to ~1.8-2.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 290k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
