Can the Apple M4 Max 128GB run DeciLM 6B?
Yes — here's how fast and up to what context, with real measured numbers.
DeciLM 6B on the Apple M4 Max 128GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 780k | 32.6-39.3 t/s | ~0.6-0.7 (slow) |
| Q8 | yes | 824k | 65.1-78.5 t/s | ~1.2-1.4 (slow) |
| Q4 | yes | 843k | 116.3-140.3 t/s | ~2.1-2.6 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
