FAQ

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

Yes. At Q4 it generates ~9.7-11.7 tok/s and fits up to 352k 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 352k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
