Stable Code 3B on the Apple M1 Ultra 64GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 771k 97.3-117.3 t/s ~1.2-1.5 (slow)
Q8 yes 813k 194.5-234.6 t/s ~2.4-2.9 (slow)
Q4 yes 832k 347.4-418.9 t/s ~4.3-5.2 (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 Stable Code 3B?โ–ถ

Yes. At Q4 it generates ~347.4-418.9 tok/s and fits up to 832k context; beyond that it spills to SSD swap and slows to ~4.3-5.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 832k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
