Safe, high-level Rust bindings to the C++ project of the same name, meant to be as user-friendly as possible. Run GGUF-based large language models directly on your CPU in fifteen lines of code, no ML experience required!
// Create a model from anything that implements `AsRef<Path>`:
let model = LlamaModel::load_from_file("path_to_model.gguf").expect("Could not load model");
// A `LlamaModel` holds the weights shared across many _sessions_; while your model may be
// several gigabytes large, a session is typically a few dozen to a hundred megabytes!
let mut ctx = model.create_session();
// You can feed anything that implements `AsRef<[u8]>` into the model's context.
ctx.advance_context("This is the story of a man named Stanley.").unwrap();
// LLMs are typically used to predict the next word in a sequence. Let's generate some tokens!
let max_tokens = 1024;
let mut decoded_tokens = 0;
// `ctx.get_completions` creates a worker thread that generates tokens. When the completion
// handle is dropped, tokens stop generating!
while let Some(next_token) = ctx.get_completions().next_token() {
println!("{}", String::from_utf8_lossy(next_token.as_bytes()));
decoded_tokens += 1;
if decoded_tokens > max_tokens {
break;
}
}This repository hosts the high-level bindings (crates/llama_cpp) as well as automatically generated bindings to
llama.cpp's low-level C API (crates/llama_cpp_sys). Contributions are welcome--just keep the UX clean!
