-# Limitations
-A common issue with RAG and LLMs is hallucination. There are two common
-approaches:
-
-1. Prompt engineering
-- This approach is the most obvious but is susceptible to prompt injection
-
-2. Build a Classifier to return the "I don't know" response
-- This approach is less obvious, requires another model, more training data,
-and fine tuning
-
-We can, in fact, use both approaches to further attempt to minimize the
-likelihood of prompt injection.
-
-This demo will display both.
