 ## Overview
 `LLM.swift` is basically a lightweight abstraction layer over [`llama.cpp`](https://github.com/ggerganov/llama.cpp) package, so that it stays as performant as possible while is always up to date. so theoretically, any model that works on [`llama.cpp`](https://github.com/ggerganov/llama.cpp) should work with this library as well.  
 It's only a single file library, so you can copy, study and modify the code however you want.
