### Perplexity (Measuring model quality)
You can pass `--perplexity` as a command line option to measure perplexity over the given prompt. For more background,
see https://huggingface.co/docs/transformers/perplexity. However, in general, lower perplexity is better for LLMs.
#### Measurements
#### Latest measurements
https://github.com/ggerganov/llama.cpp/pull/270 is the unofficial tracking page for now. llama.cpp is measuring very well
The latest perplexity scores for the various model sizes and quantizations are being tracked in [discussion #406](https://github.com/ggerganov/llama.cpp/discussions/406). `llama.cpp` is measuring very well
compared to the baseline implementations. Quantization has a small negative impact to quality, but, as you can see, running
13B at q4_0 beats the 7B f16 model by a significant amount.
