Best quantization choices
Approximate memory per quantization (weights + KV cache at modest context). Treat as ±.
| Quant | ~Memory | When to use |
|---|---|---|
| Q4_K_M | ~8GB | Best size/quality trade-off — the usual default for local serving. |
| Q8_0 | ~13GB | Higher fidelity; ~1.7× the memory of 4-bit. |
| FP16 | ~24GB | Full precision; largest footprint, best quality. |
