QuantFits?Max contextSpeedBeyond context
FP16 yes 114k 4.1-4.9 t/s ~0.1-0.1 (slow)
Q8 yes 318k 8.1-9.8 t/s ~0.1-0.1 (slow)
Q4 yes 408k 14.5-17.5 t/s ~0.2-0.2 (slow)

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

Can the Apple M2 Ultra 192GB run DeepSeek LLM 67B?โ–ถ

Yes. At Q4 it generates ~14.5-17.5 tok/s and fits up to 408k context; beyond that it spills to SSD swap and slows to ~0.2-0.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 408k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
