Chat UI supports the llama.cpp API server directly without the need for an adapter. You can do this using the `llamacpp` endpoint type.

If you want to run Chat UI with llama.cpp, you can do the following, using [microsoft/Phi-3-mini-4k-instruct-gguf](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-gguf) as an example model:

```bash
# install llama.cpp
brew install llama.cpp
# start llama.cpp server
llama-server --hf-repo microsoft/Phi-3-mini-4k-instruct-gguf --hf-file Phi-3-mini-4k-instruct-q4.gguf -c 4096
```

_note: you can swap the `hf-repo` and `hf-file` with your fav GGUF on the [Hub](https://huggingface.co/models?library=gguf). For example: `--hf-repo TheBloke/TinyLlama-1.1B-Chat-v1.0-GGUF` for [this repo](https://huggingface.co/TheBloke/TinyLlama-1.1B-Chat-v1.0-GGUF) & `--hf-file tinyllama-1.1b-chat-v1.0.Q4_0.gguf` for [this file](https://huggingface.co/TheBloke/TinyLlama-1.1B-Chat-v1.0-GGUF/blob/main/tinyllama-1.1b-chat-v1.0.Q4_0.gguf)._

A local LLaMA.cpp HTTP Server will start on `http://localhost:8080` (to change the port or any other default options, please find [LLaMA.cpp HTTP Server readme](https://github.com/ggerganov/llama.cpp/tree/master/examples/server)).

Add the following to your `.env.local`:

```ini
