1919
* GPU - Run `0-setup.bat` (Windows) `0-setup.sh` (Linux).
20-
* CPU - Run `0-setup.bat CPU` (Windows) `0-setup.sh CPU` (Linux). You will need to manually download your own model, see "changing models" below.
21-
* Access `http://your-site.com/ai/` for the demo.
20+
* CPU - Run `0-setup.bat CPU` (Windows) `0-setup.sh CPU` (Linux).
21+
* You will need to [choose and download an AI model](https://code-boxx.com/core-boxx-ai-chatbot/#sec-choose).
22+
* Run `2-bot.bat 2-bot.sh`, access `http://your-site.com/ai/` for the demo.
