Practical use of small LLMs — criteria for choosing 7B–32B models

We have organized models that are usable in the field based on VRAM, throughput, and Korean performance.

Model size is directly tied to VRAM. Based on 4-bit quantization, approximately the same number of GB as the model size is required.

Korean-language performance

English benchmark rankings do not carry over unchanged to Korean. You must compare using actual work documents.

The largest model is not always the best. Most field work is sufficient with 7–14B.
