This MacOS app used to be called LlamaBarn. Really excellent to see the fast progress being made.

Official repo, also has documentation how to configure server parameters:

Small tip, install llama.cpp with brew before llama.app, which will pick up the existing llama.cpp. That way it's easier to stay up to date with llama.cpp, since llama.app is on a slower release cadence.

Also, models installed with the hugging face CLI (hf) are picked up by llama.app automatically. The CLI will keep the model cache updated, e.g. when models get updated.

Llama.cpp became part of Huggingface recently.
