Does this actually need to be local? Since the chat bot is open to the public and I assume the course material used for RAG all on this page (https://canvas.illinois.edu/courses/54315/pages/exam-schedul...) all stays freely accessible - I clicked a few links without being a student - I assume a pre-prompted larger non-local LLM would outperform the local instance. Though, you can imagine an equivalent course with all of its content ACL-gated/'paywalled' could benefit from local RAG, I guess.
