FAQ

Can the Apple M2 Ultra 64GB run LLaVA-NeXT-34B (LLaVA-1.6)?โ–ถ

Yes. At Q4 it generates ~28-33.7 tok/s and fits up to 140k context; beyond that it spills to SSD swap and slows to ~0.3-0.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 140k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
