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 InternLM2.5?โ–ถ

Yes. At Q4 it generates ~18.2-22 tok/s and fits up to 75k context; beyond that it spills to SSD swap and slows to ~0.6-0.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 75k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
