| # Daytona Beach Ambassador | |
| This Space demonstrates a [long prompt](https://huggingface.co/spaces/kananj/Daytona-Beach-Ambassador/blob/main/daytona.py) running on the base model [Llama-2-13b-chat](https://huggingface.co/meta-llama/Llama-2-13b-chat). | |
| The prompt instructs the AI to be "helpful, respectful and honest ambassador for Daytona Beach Florida". The prompt then loads in the [Wikipedia page for Daytona Beach, Florida](https://en.wikipedia.org/wiki/Daytona_Beach,_Florida), slight shortened so it can fit into the token limit. | |
| It will attempt to answer questions about Daytona Beach, while also encouraging you to visit! | |
