CVS Health releases UQLM: Open‑source tool for LLM hallucination detection via uncertainty quantification
CVS Health has open‑sourced UQLM, a Python library that detects hallucinations in LLM outputs by quantifying uncertainty. The tool offers black‑box, white‑box, LLM‑as‑judge and ensemble scorers that work with any model, letting enterprises add a safety layer without modifying the underlying LLM.
