FP16 yes 319k 18.1-21.9 t/s ~0.2-0.3 (slow)
Q8 yes 377k 36.3-43.7 t/s ~0.5-0.5 (slow)
Q4 yes 402k 64.8-78.1 t/s ~0.8-1 (slow)

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

FAQ

Can the Apple M1 Ultra 128GB run FunSearch?โ–ถ

Yes. At Q4 it generates ~64.8-78.1 tok/s and fits up to 402k context; beyond that it spills to SSD swap and slows to ~0.8-1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 402k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
