FAQ

Can the Apple M1 Ultra 128GB run GLM-130B?โ–ถ

Yes. At Q4 it generates ~7.5-9 tok/s and fits up to 125k 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 125k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
