FAQ

Can the Apple M1 Ultra 64GB run Karakuri LM?โ–ถ

Yes. At Q4 it generates ~13.9-16.7 tok/s and fits up to 52k 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 52k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
