FP16 yes 1701k 247.3-298.2 t/s ~3.1-3.7 (slow)
Q8 yes 1718k 494.5-596.4 t/s ~6.2-7.5 (slow)
Q4 yes 1726k 883.1-1064.9 t/s ~11-13.3 (slow)

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

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

Yes. At Q4 it generates ~883.1-1064.9 tok/s and fits up to 1726k context; beyond that it spills to SSD swap and slows to ~11-13.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1726k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
