FAQ

Can the Apple M4 Max 36GB run Flan UL2?โ–ถ

Yes. At Q4 it generates ~34-41 tok/s and fits up to 76k context; beyond that it spills to SSD swap and slows to ~0.6-0.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 76k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
