Classic fact-checking setups rarely fit this case. They usually assume that the claim to check, or the evidence for it, is already given. LLM outputs instead come without either, and they are long, with no clear unit… 2. **[Halu-J: Critique-Based Hallucination Judge](https://md.research.elamur.ai/free/en/papers/wang-2024-halu-j-critique-based-hallucination/)** *(2024 · 8 citations)* LLMs often produce factually wrong statements.
