## What's inside?

Combines [LFM2.5-Audio-1.5B](https://huggingface.co/LiquidAI/LFM2.5-Audio-1.5B-GGUF) in TTS and STT modes with [LFM2-1.2B-Tool](https://huggingface.co/LiquidAI/LFM2-1.2B-Tool-GGUF) within a mockup of a car cockpit, letting the user control the car functionalities by voice.

All running locally in real-time.

## Key Components

[Llama.cpp](https://github.com/ggml-org/llama.cpp) is used for both models inference, with a custom runner for the audio model. The car cockpit (UI) is vanilla js+html+css, and the communication with the backend is through messages over websocket, like a widely simplified [car CAN bus](https://en.wikipedia.org/wiki/CAN_bus).

   ln -s $(which llama-server) llama-server
   ```

3. Prepare the audio and tool calling models:
   ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}}
