About llama.cpp

llama.cpp is an inference engine for large language models, written in C and C++ and maintained under the ggml organization. Its repository describes it as LLM inference in C and C++ and includes a server, a library API and command-line tools for running GGUF model files on local hardware.

Many other local AI tools build on it. The Jan and GPT4All projects in this category and the llamafile project all list llama.cpp among their foundations. Because it is a low-level engine, llama.cpp suits developers and people who are comfortable with the command line. Users who want a graphical app are better served by Jan or GPT4All. The MIT license allows commercial use and modification.
