Yes — here's how fast and up to what context, with real measured numbers.
SANA 1.5 4.8B on the Apple M2 Max 32GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 270k | 28.3-34.2 t/s | ~0.7-0.9 (slow) |
| Q8 | yes | 343k | 56.7-68.3 t/s | ~1.4-1.7 (slow) |
| Q4 | yes | 376k | 101.2-122 t/s | ~2.5-3.1 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
