Celebrating 2 Million Downloads of HHEM

Vectara's Hallucination Evaluation Model (HHEM) has surpassed 2 million downloads as it continues to be a leading solution for detecting hallucinations in enterprise Retrieval-Augmented Generation (RAG) pipelines. Since its launch, HHEM has been improved with updates such as HHEM-2.1 and an open source version. The model provides a score that quantifies the level of trust in responses from RAG pipelines, helping to reduce hallucinations in enterprise applications. With significant growth in usage, HHEM is becoming increasingly important for mission-critical RAG applications where accuracy is paramount.
