Can the Apple M4 Max 48GB run AWD-LSTM-MoS + dynamic evaluation (PTB, 2018)?

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

AWD-LSTM-MoS + dynamic evaluation (PTB, 2018) on the Apple M4 Max 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 636k 7735-9327.5 t/s ~141.7-170.8 (slow)
Q8 yes 636k 15470-18655 t/s ~283.3-341.7 (slow)
Q4 yes 636k 27625-33312.5 t/s ~506-610.1 (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 M4 Max 48GB run AWD-LSTM-MoS + dynamic evaluation (PTB, 2018)?โ–ถ

Yes. At Q4 it generates ~27625-33312.5 tok/s and fits up to 636k context; beyond that it spills to SSD swap and slows to ~506-610.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 636k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
