This is a langchain for some mysterious hackathon.

Demo

Currently, I build a sample Langchain application to see how langchain communicate with PDF file and response with help from OpenAI API.

How to start?

1. Create .env file with your own "OPENAI_API_KEY" and "TAVILY_API_KEY".
2. Start LangServe: python example.py
3. Go to http://localhost:8000 to how langchain intermediate steps work. You can ask questions about DARPA internet protocol design.

Structure

1. /sample: here comes some PDF files we want our chatbot knows.
2. example.py: the langchain server, currently does:
   • Load PDF file
   • Convert PDF content to embedding vectors
   • Create retriever tools to help search content based on user input
   • Create agent to actually execute prompt in specific model (I use "GPT-3.5-Turbo" for test)
   • Receive user input and generate output to user
3. client.py: currently works as a client to send question. This should be replaced with Discord Bot.
