Configuration Summary

The following hardware specifications are typical for each model version when deployed locally:

1.5B – 4 CPU cores+, 8 GB RAM+, optional GPU (≥4 GB VRAM, e.g., GTX 1650/RTX 2060).

7B – 8 CPU cores+, 16 GB RAM+, GPU ≥8 GB VRAM (e.g., RTX 3070/4060).

8B – same as 7B.

14B – 12 CPU cores+, 32 GB RAM+, GPU ≥16 GB VRAM (e.g., RTX 4090/A5000).

32B – 16 CPU cores+, 64 GB RAM+, GPU ≥24 GB VRAM (e.g., A100 40GB).

70B – 32 CPU cores+, 128 GB RAM+, multi‑GPU setup (e.g., 2×A100 80GB).

671B – 64 CPU cores+, 512 GB RAM+, multi‑GPU cluster (e.g., 8×A100/H100).

Note that the listed configurations represent typical upper bounds; actual requirements may be lower if you can tolerate reduced performance or quality.
