Can the Apple M1 Ultra 64GB run Adaptive Inputs + LayerDrop?
Yes — here's how fast and up to what context, with real measured numbers.
Adaptive Inputs + LayerDrop on the Apple M1 Ultra 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 843k | 643-775.4 t/s | ~8-9.7 (slow) |
| Q8 | yes | 850k | 1286.1-1550.8 t/s | ~16.1-19.4 (slow) |
| Q4 | yes | 852k | 2296.5-2769.3 t/s | ~28.7-34.6 (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 Adaptive Inputs + LayerDrop?▶
Yes. At Q4 it generates ~2296.5-2769.3 tok/s and fits up to 852k context; beyond that it spills to SSD swap and slows to ~28.7-34.6 tok/s.
How much context fits?▶
At Q4, up to about 852k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
