announce: guile_llama_cpp 0.1 release

# guile_llama_cpp

GNU Guile binding for llama.cpp

This is version 0.1, Copyright 2024 Li-Cheng (Andy) Tai, [email protected]
Available as https://codeberg.org/atai/guile_llama_cpp/releases/download/0.1/guile_llama_cpp-0.1.tar.gz


Guile_llama_cpp wraps around llama.cpp APIs so llama.cpp can be
accessed from Guile scripts and programs, in a manner
similar to llama-cpp-ython allowing the use of llama.cpp in Python programs.

Currently a simple Guile script is provided to allow simple "chat"
with a LLM in gguf format.

## setup and build

guile_llama_cpp is written in GNU Guile and C++ and requires

Swig 4.0 or later, GNU guile 3.0, and llama.cpp (obviosuly)

installed on your system.

From sources, guile_llama_cpp can be built via the usual GNU convention,

export LLAMA_CFLAGS=-I<llama_install_dir>/include
export LLAMA_LIBS=-L<llama_install_dir>/lib -lllama

./configure --prefix=<install dir>
make
make install

Once in the future llama.cpp provides pkg-config support, the first
two "export" lines can be omitted.

If you are running GNU Guix on your system, you can get a shall with
all needed dependencies set up with

guix shell -D -f guix.scm

and then use the usual

configure && make && make install

commands to build.

## run

To use guile_llama_cpp to chat with a LLM (Large Language Model), you
need to first download a LLM in gguf format.
See instructions on the web such as
https://stackoverflow.com/questions/67595500/how-to-download-a-model-from-huggingface

As an example, using a "smaller" LLM "Phi-3-mini" from Microsoft; we
would first download the model in gguf format via wget:

wget https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-gguf/resolve/main/Phi-3-mini-4k-instruct-q4.gguf

then you can chat with it, in the build directory:

./pre-inst-env simple.scm  "What are the planets?"
Phi-3-mini-4k-instruct-q4.gguf

The general form to do a chat with a model is to invoke the script
scripts/simple.scm

simple.scm prompt_text model_file_path

in the build directory, pretend the command with

./pre-inst-env

as it sets up the needed paths and environment variables for proper
guile invocation.

Currently, the chat supported is limited; you would see the replies
from the LLM cut of after a sentence or so.
The outputs length issue will be further addressed in future releases.

## roadmap

* support for continuous chat, with long replies
* support for expose the LLM as a web end point, using a web server
built in Guile, so
  the LLM can be done via a web interface, to allow chatting with remote users
* support for embedding LLMs in Guile programs for scenarios like LLM
driven software
  agents
