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
