FP16 yes 208k 24.7-29.8 t/s ~0.3-0.4 (slow)
Q8 yes 275k 49.5-59.6 t/s ~0.6-0.7 (slow)
Q4 yes 305k 88.3-106.5 t/s ~1.1-1.3 (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 64GB run Unicorn?โ–ถ

Yes. At Q4 it generates ~88.3-106.5 tok/s and fits up to 305k context; beyond that it spills to SSD swap and slows to ~1.1-1.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 305k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
