A team of researchers based at the University of Waterloo have created a new tool – nicknamed “RAGE” – that reveals where large language models (LLMs) like ChatGPT are getting their information and whether that information can be trusted.

Furthermore, LLMs are prone to “hallucination” – that is, they write convincingly about concepts and sources that are either incorrect or nonexistent.

“You can’t necessarily trust an LLM to explain itself,” said Joel Rorseth, a Waterloo computer science PhD student and lead author on the study. “It might provide explanations or citations that it has also made up.”
