Can the Apple M2 Ultra 192GB run Transformer (Adaptive Input Embeddings) WT103?

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

Transformer (Adaptive Input Embeddings) WT103 on the Apple M2 Ultra 192GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 2606k 1101.2-1327.9 t/s ~13.8-16.6 (slow)
Q8 yes 2610k 2202.4-2655.9 t/s ~27.5-33.2 (slow)
Q4 yes 2612k 3932.9-4742.6 t/s ~49.2-59.3 (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 192GB run Transformer (Adaptive Input Embeddings) WT103?โ–ถ

Yes. At Q4 it generates ~3932.9-4742.6 tok/s and fits up to 2612k context; beyond that it spills to SSD swap and slows to ~49.2-59.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 2612k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
