Can the Apple M2 Ultra 64GB run DEQ-Transformer (Post-LN) + Jacobian Regularisation?

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

DEQ-Transformer (Post-LN) + Jacobian Regularisation on the Apple M2 Ultra 64GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 853k 2775.5-3346.9 t/s ~34.7-41.8 (slow)
Q8 yes 855k 5551-6693.9 t/s ~69.4-83.7 (slow)
Q4 yes 855k 9912.5-11953.4 t/s ~123.9-149.4 (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 M2 Ultra 64GB run DEQ-Transformer (Post-LN) + Jacobian Regularisation?โ–ถ

Yes. At Q4 it generates ~9912.5-11953.4 tok/s and fits up to 855k context; beyond that it spills to SSD swap and slows to ~123.9-149.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 855k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
