llama.cpp/example/embedding

This example demonstrates generate high-dimensional embedding vector of a given text with llama.cpp.

Quick Start

To get started right away, run the following command, making sure to use the correct path for the model you have:

Unix-based systems (Linux, macOS, etc.):

./llama-embedding -m ./path/to/model --pooling mean --log-disable -p "Hello World!" 2>/dev/null

Windows:

llama-embedding.exe -m ./path/to/model --pooling mean --log-disable -p "Hello World!" 2>$null

The above command will output space-separated float values.

extra parameters

--embd-normalize $integer$

$integer$descriptionformula
$-1$none
$0$max absolute int16$\Large{{32760 * x_i} \over\max \lvert x_i\rvert}$
$1$taxicab$\Large{x_i \over\sum \lvert x_i\rvert}$
$2$euclidean (default)$\Large{x_i \over\sqrt{\sum x_i^2}}$
$>2$p-norm$\Large{x_i \over\sqrt[p]{\sum \lvert x_i\rvert^p}}$
