// RUN — FITS

Can the Apple M3 Max 128GB run Xinyuan (心元大模型)?

Yes — here's how fast and up to what context, with real measured numbers.

Xinyuan (心元大模型) on the Apple M3 Max 128GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 523k 9.7-11.7 t/s ~0.2-0.3 (slow)
Q8 yes 609k 19.4-23.4 t/s ~0.5-0.6 (slow)
Q4 yes 646k 34.7-41.8 t/s ~0.9-1 (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 M3 Max 128GB run Xinyuan (心元大模型)?

Yes. At Q4 it generates ~34.7-41.8 tok/s and fits up to 646k context; beyond that it spills to SSD swap and slows to ~0.9-1 tok/s.

How much context fits?

At Q4, up to about 646k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
