Hallucination Leaderboard

Public LLM leaderboard computed using Vectara's Hughes Hallucination Evaluation Model. This evaluates how often an LLM introduces hallucinations when summarizing a document. We plan to update this regularly as our model and the LLMs get updated over time. Also, feel free to check out our hallucination leaderboard on Hugging Face. The rankings in this leaderboard are computed using the HHEM-2.1 hallucination evaluation model. If you are interested in the previous leaderboard, which was based on HHEM-1.0, it is available here for more details.
