Best quantization choices

Approximate memory per quantization (weights + KV cache at modest context). Treat as ±.

Quant~MemoryWhen to use
Q4_K_M~44GBBest size/quality trade-off — the usual default for local serving.
Q8_0~78GBHigher fidelity; ~1.7× the memory of 4-bit.
FP16~145GBFull 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.
