llama-cpp-rs

llama-cpp-rs  

This is the home for llama-cpp-2. It also contains the llama-cpp-sys bindings which are updated semi-regularly and in sync with llama-cpp-2.

This project was created with the explict goal of staying as up to date as possible with llama.cpp, as a result it is dead simple, very close to raw bindings, and does not follow semver meaningfully.

Check out the docs.rs for crate documentation or the readme for high level information about the project.

Try it

We maintain a super simple example of using the library:

Clone the repo

git clone --recursive https://github.com/utilityai/llama-cpp-rs
cd llama-cpp-rs

Run the simple example (add --features cuda if you have a cuda gpu)

cargo run --release --bin simple -- --prompt "The way to kill a linux process is" hf-model TheBloke/Llama-2-7B-GGUF llama-2-7b.Q4_K_M.gguf

Hacking

Ensure that when you clone this project you also clone the submodules. This can be done with the following command:

git clone --recursive https://github.com/utilityai/llama-cpp-rs

or if you have already cloned the project you can run:

git submodule update --init --recursive
