# Local model quantization

> Create smaller GGUF models with a safe preview-first workflow.

```bash theme={null}
arka quantize model-f16.gguf --output model-q4.gguf --type Q4_K_M
arka quantize model-f16.gguf --output model-q4.gguf --type Q4_K_M --run
```

The first command previews the `llama-quantize` command. `--run` is required to
execute it, and the output directory is created automatically. Install a
llama.cpp build exposing `llama-quantize` before running conversions.
