// RUN — FITS
Can the Apple M4 Max 64GB run CPM-Bee?
Yes — here's how fast and up to what context, with real measured numbers.
CPM-Bee on the Apple M4 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 220k | 18.6-22.4 t/s | ~0.3-0.4 (slow) |
| Q8 | yes | 281k | 37.1-44.8 t/s | ~0.7-0.8 (slow) |
| Q4 | yes | 308k | 66.3-80 t/s | ~1.2-1.5 (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 64GB run CPM-Bee?▶
Yes. At Q4 it generates ~66.3-80 tok/s and fits up to 308k context; beyond that it spills to SSD swap and slows to ~1.2-1.5 tok/s.
How much context fits?▶
At Q4, up to about 308k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
