Penn Course LLM (PCL) is a RAG-based Chatbot built to help Penn students search, plan and explore courses at UPenn more easily. Users can chat with the LLM, save their interaction sessions and share their sessions via a public link.

Features Requests

• Agent-based approach for more complex answers
• More connectors (with web, Penn-related products, etc) to enrich responses
• Reduce latency with saving chat sessions
• Include citations

Technologies

The project uses Next.js (frontend + server functions), Cohere (LLM) and Vercel KV (data store for chat sessions)

How to run

Run app locally on your computer. Available on localhost:3000

$ npm install
$ npm run dev

Cohere Connector

This app uses the Cohere Connector API for RAG (Retrieval Augmented Generation) functionality. This is a Flask server running a /search endpoint for Cohere to query relevant documents.

Run Cohere Connector

First, generate embeddings courses_graph.json using Cohere Embed

python run dev/generate_embeddings.py

Secondly, load embeddings into a Pinecone instance,

python run dev/load_data.py

Thirdly, run the Flask serving the document search functionality

poetry run flask --app provider --debug run

You can now test the endpoint like so:

  curl --request POST \
    --url http://localhost:5000/search \
    --header 'Content-Type: application/json' \
    --header 'Authorization: Bearer {PINECONE_CONNECTOR_API_KEY} \
    --data '{
    "query": "BBQ"
  }'

Deployment

Uses Vercel for quick deployment

$ vercel deploy
