Abstract
Certain aspects of the disclosure provide a method for unsupervised detection of hallucinations in generative language model outputs. The method includes receiving a language model output comprising tokens and corresponding confidence scores, identifying low-confidence tokens whose scores fall below a confidence score threshold, and determining unsupervised attributes of these tokens. An anomaly score is then calculated based on the unsupervised attributes, and if this score meets or exceeds a set threshold, the system predicts that the language model output contains at least one hallucination.
