Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.

FAQ

Can the Apple M4 Max 128GB run Stable Beluga 1?โ–ถ

Yes. At Q4 it generates ~10.2-12.3 tok/s and fits up to 236k 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 236k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
