#### Local LLM (optional) #### Local LLM (optional)
The application supports running a local LLM, using Ollama. If you would like to run the application using a local LLM backend (`-b local` flag), you need to install Ollama.
To install Ollama, please run following commands
```bash ```bash
curl -fsSL https://ollama.com/install.sh | sh # install Ollama curl -fsSL https://ollama.com/install.sh | sh # install Ollama
ollama pull llama3.1:8b # fetch and dowload specific model ollama pull llama3.1:8b # fetch and download as model
``` ```
Include the model in the `.env` file: Include the downloaded model in the `.env` file:
```text ```text
LOCAL_CHAT_MODEL="llama3.1:8b" LOCAL_CHAT_MODEL="llama3.1:8b"
LOCAL_EMB_MODEL="llama3.1:8b" LOCAL_EMB_MODEL="llama3.1:8b"
``` ```
And run the generic RAG demo with the `-b local` flag.
