Q4 yes 1729k 1377.6-1661.3 t/s ~17.2-20.8 (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 data2vec (language)?โ–ถ

Yes. At Q4 it generates ~1377.6-1661.3 tok/s and fits up to 1729k context; beyond that it spills to SSD swap and slows to ~17.2-20.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1729k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
