Best quantization choices
Approximate memory per quantization (weights + KV cache at modest context). Treat as ±.
| Quant | ~Memory | When to use |
|---|---|---|
| Q4_K_M | ~44GB | Best size/quality trade-off — the usual default for local serving. |
| Q8_0 | ~78GB | Higher fidelity; ~1.7× the memory of 4-bit. |
| FP16 | ~145GB | Full precision; largest footprint, best quality. |

Frequently asked questions
What hardware do I need to run Qwen2.5 72B?+
At 4-bit you need roughly ~44GB of usable memory. The minimum self-hostable option in our catalog is the Apple Mac mini (M4 Pro). For a comfortable run we recommend the NVIDIA B200 (placeholder).
Which quantization should I use for Qwen2.5 72B?+
Q4_K_M is the usual default — the best size/quality trade-off. Step up to Q8_0 or FP16 if you have spare memory and want higher fidelity.
Should I run Qwen2.5 72B locally or in the cloud?+
Hybrid is recommended for Qwen2.5 72B. Run it locally where it fits and burst to the cloud for peaks or larger jobs.
