This repo is a simple demonstration of using langchain to do fact-checking with prompt chaining. How it works:
- you ask your desired LLM a question
- the LLM generates an initial answer to the question
- the LLM self-interrogates what the assumptions were that went into that answer
- the LLM sequentially determines if each of these assumptions are true
- the LLM generates a new answer to the question, incorporating the new information
Make sure you have langchain installed (pip install langchain
). Then run
python3 fact_checker.py 'insert question here'
Be sure to wrap your question in quotes if you're passing it as a command line argument.
Alternatively, you can use the provided fact_checker.ipynb
notebook.
Question: "What type of mammal lays the biggest eggs?"
Initial answer: The biggest eggs laid by any mammal belong to the elephant.
Assumptions made:
- The elephant is a mammal
- Mammals lay eggs
- Eggs come in different sizes
- Elephants lay bigger eggs than other mammals
Verification of assumptions:
- The elephant is a mammal: TRUE
- Mammals lay eggs: FALSE - Most mammals give birth to live young.
- Eggs come in different sizes: TRUE
- Elephants lay bigger eggs than other mammals: FALSE - Elephants do not lay eggs.
New answer: This question cannot be answered because elephants do not lay eggs and most mammals give birth to live young.
