Best quantization choices
Approximate memory per quantization (weights + KV cache at modest context). Treat as ±.
| Quant | ~Memory | When to use |
|---|---|---|
| Q4_K_M | ~400GB | Best size/quality trade-off — the usual default for local serving. |
| Q8_0 | ~700GB | Higher fidelity; ~1.7× the memory of 4-bit. |
| FP16 | ~1340GB | Full precision; largest footprint, best quality. |

Frequently asked questions
What hardware do I need to run DeepSeek-R1 671B (MoE)?+
At 4-bit you need roughly ~400GB of usable memory. The minimum self-hostable option in our catalog is the Supermicro 8x H100 SuperServer. For a comfortable run we recommend the Supermicro 8x H100 SuperServer.
Which quantization should I use for DeepSeek-R1 671B (MoE)?+
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 DeepSeek-R1 671B (MoE) locally or in the cloud?+
Cloud / API is recommended for DeepSeek-R1 671B (MoE). Its size or hosting model makes the cloud the practical choice; pair with smaller local models for everyday private work.
