Llama is a macOS menu bar app for running local LLMs.
brew install --cask llama-app
Or download from Releases.
When you start Llama, it runs a local server at http://localhost:9931/v1
.
If you have llama.cpp installed, Llama uses it. Otherwise, it installs a prebuilt binary for your Mac. Models you've already installed via llama.cpp show up in the app automatically. You can install any GGUF model from Hugging Face, and Llama also recommends models that fit your Mac's hardware.
You can chat with any model in the built-in WebUI, connect other apps (coding agents, chat UIs, editors), or use the API directly. Models load when requested and unload when idle, so they don't take up memory when not in use.

List installed models:
curl http://localhost:9931/v1/models
Send a message to a model:
curl http://localhost:9931/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"model": "ggml-org/gpt-oss-20b-GGUF:MXFP4",
"messages": [{"role": "user", "content": "Hello"}]
}'
See complete API reference in the llama.cpp server docs.
Expose to network — By default, the server is only accessible from your Mac (localhost
). This option allows connections from other devices on your local network. Only enable this if you understand the security risks.
defaults write app.llama.Llama exposeToNetwork -bool YES
defaults write app.llama.Llama exposeToNetwork -string "100.x.x.x"
defaults delete app.llama.Llama exposeToNetwork
Custom server arguments — Extra CLI arguments appended to the llama serve
command, for server flags the app doesn't expose (e.g. --api-key
). They come after the app's own flags, so where the server honors the later occurrence they can override the app's settings. Takes effect on the next server start.
defaults write app.llama.Llama extraServerArgs -string "--api-key secret"
defaults delete app.llama.Llama extraServerArgs
