Run the interactive chatbot

This application is an interactive chatbot that answers questions about coffee and built with a RAG design pattern. Workflow is a python program using Langchain LLM orchestration framework. The vector dataset is built using text-embedding-3-large embedding model from OpenAI from a local dataset about coffee. The vector data is stored in a local filebased Chroma vectorDB. The app uses OpenAI gpt-4o-mini model for inference.

Example output

$ python lc-openai-with-okahu.py 

Ask a coffee question [Press return to exit]: What is an americano?
An americano is a type of coffee drink that is made by diluting an espresso shot with hot water at a 1:3 to 1:4 ratio, resulting in a drink that retains the complex flavors of espresso, but in a lighter way.

Okahu instrumentation

To run the chatbot app without Okahu instrumentation, use the command python lc-openai.py
