Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.

FAQ

Can the Apple M2 Ultra 192GB run AREX Base?โ–ถ

Yes. At Q4 it generates ~8-9.6 tok/s and fits up to 314k context; beyond that it spills to SSD swap and slows to ~0.1-0.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 314k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
