Challenge: Currently, tool-augmented large language models (LLMs) only achieve total scores of 45.3 and 37.0, respectively, on a scale of 100.
Approach: They propose a multi-level diagnostic process to assess the LLM's hallucinations through two perspectives: depth and breadth.
Outcome: The proposed diagnostic process assesses the hallucinations of large language models through two perspectives: depth and breadth.
