emb.c - Vector Embedding Library

emb.c is a portable C library and CLI for generating vector embeddings from text using a GGML-based model. It is designed as a composable primitive.

CLI

Generate vector embeddings from command-line arguments or standard input.

Examples

Single sentence embedding:

./bin/x86_64/linux/emb "The quick brown fox"

Batch processing via standard input:

echo "The quick brown fox" | ./bin/x86_64/linux/emb
cat sentences.txt | ./bin/x86_64/linux/emb

Parameters

Output

Results are printed as space-separated floats, one line per input text:

0.123456 0.234567 ... 0.345678

Public API

#include "emb.h"

kc_emb_t *ctx = kc_emb_open();
int dim = kc_emb_dim(ctx);
float *vec = malloc(dim * sizeof(float));

kc_emb_exec(ctx, "The quick brown fox", vec);

kc_emb_close(ctx);

Lifecycle

• kc_emb_open() - allocates and prepares a new embedding context.
• kc_emb_exec() - generates an embedding for the given text. Multiple calls on the same context are serialized.
• kc_emb_close() - releases the context and all associated resources.

Build

Compiled artifacts are generated under bin/{arch}/{platform}/ for the host architecture running the build.

make clean && make

Multiarch Builds

The project is prepared to build artifacts for multiple architectures under bin/{arch}/{platform}/. A plain make builds only the current host architecture, while the targets below build the full matrix or a specific target.

Dependencies

Beta Notice

This is a beta project tested only on Debian x86_64. It was created out of a personal need for these libraries, but no guarantees are provided regarding its stability or future support. You are free to test it, use it, and modify it as you please.

If you'd like to reach out, you can send an email to [email protected]. Please note that I do not accept pull requests; the goal is to avoid long-term dependency on platforms like GitHub, and I do not maintain fixed infrastructure to guarantee long-term stability for these projects.
