Hhem 2 1 Announcements Vectara Forums Public llm leaderboard computed using vectara's hallucination evaluation model, also known as hhem. this evaluates how often an llm introduces hallucinations when summarizing a document. Hhem performs binary factual consistency classification on llm generated summaries to detect hallucinations. this page covers the technical architecture, version history, classification mechanism, and integration details of hhem models. The vectra hhem evaluator, or hughes hallucination evaluation model, is a tool used to determine if a summary produced by a large language model (llm) might contain hallucinated information.

In april 2024, we introduced hhem 2.0 with improved accuracy, longer sequences, and multilingual support. The hhem model is an open source model, created by vectara, for detecting hallucinations in llms. it is particularly useful in the context of building retrieval augmented generation (rag) applications where a set of facts is summarized by an llm, but the model can also be used in other contexts. Vectara uses the hughes hallucination evaluation model (hhem) to assess the likelihood of ai generated summary being factually consistent based on search results. this calibrated score can range from 0.0 to 1.0. The hhem 2.1 model was trained on various open source datasets from factual consistency research in summarization. it systematically compares source documents with their summaries to identify statements that cannot be verified from the source.
