embedding

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 $integer$

$integer$	description	formula
$-1$	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	$\Large{x_i \over\sqrt[p]{\sum \lvert x_i\rvert^p}}$

--embd-output-format $'string'$

$'string'$	description
''	same as before	(default)
'array'	single embeddings	$[[x_1,...,x_n]]$
	multiple embeddings	$[[x_1,...,x_n],[x_1,...,x_n],...,[x_1,...,x_n]]$
'json'	openai style
'json+'	add cosine similarity matrix

--embd-separator $"string"$

$"string"$
"\n"	(default)
"<#embSep#>"	for exemple
"<#sep#>"	other exemple
