🍇🥑 LlamaIndex - Chat with the Nutrition AI

A chatbot powered by LlamaIndex that augments GPT 3.5 with the contents of the Human Nutrition textbook by University of Hawaii Food Science and Human Nutrition Program.

Overview of the App

• Takes user queries via Streamlit's st.chat_input and displays both user queries and model responses with st.chat_message
• Uses LlamaIndex to load and index data and create a chat engine that will retrieve context from that data to respond to each user query

Demo App

Get an OpenAI API key

You can get your own OpenAI API key by following the following instructions:

1. Go to https://platform.openai.com/account/api-keys.
2. Click on the + Create new secret key button.
3. Next, enter an identifier name (optional) and click on the Create secret key button.
4. Add your API key to your secrets.toml file. If you don't already have a secrets.toml file, add a folder named .streamlit, create a file called secrets.toml within the folder, and add the following to it: openai_key = <your key here>

Alternatively, you can use Streamlit Community Cloud's secrets management feature to add your API key via the web interface.

Caution
