arXiv:2502.15845v2 Announce Type: replace Abstract: Large Language Models (LLMs) often hallucinate, limiting their reliability in sensitive applications. In black-box settings, several self-consistency-based techniques have been proposed for hallucination detection. We empirically show that these methods perform nearly as well as a supervised (black-box) oracle, leaving limited room for further gains within this paradigm. To address this limitation, we explore cross-model consistency checking between the target model and an additional verifier LLM. With this extra information, we observe impro
The proliferation of LLM applications necessitates robust methods for ensuring factual accuracy, making hallucination detection a critical and active area of research.
Reliable hallucination detection is crucial for the widespread adoption of LLMs in sensitive domains, directly impacting their trustworthiness and applicability.
This research suggests a pivot from pure self-consistency to cross-model verification for improved hallucination detection in black-box LLMs.
