Can the Apple M4 Max 64GB run CodeGen2?
Yes — here's how fast and up to what context, with real measured numbers.
CodeGen2 on the Apple M4 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 92k | 11.6-14 t/s | ~0.2-0.3 (slow) |
| Q8 | yes | 153k | 23.2-28 t/s | ~0.4-0.5 (slow) |
| Q4 | yes | 180k | 41.4-50 t/s | ~0.8-0.9 (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 CodeGen2?▶
Yes. At Q4 it generates ~41.4-50 tok/s and fits up to 180k context; beyond that it spills to SSD swap and slows to ~0.8-0.9 tok/s.
How much context fits?▶
At Q4, up to about 180k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
