BEACON: Behavioral Entropy Aggregation for Cross-Model Hallucination Detection in Large Language Models
arXiv:2606.07528v1 Announce Type: cross Abstract: Hallucination in large language models (LLMs), defined as the generation of factually incorrect or unsupported content, remains a critical barrier to reliable deployment. We present BEACON (Behavioral Entropy Aggregation for Cross-model hallucination detectiON), a black-box hallucination detection framework that operates purely on model outputs without requiring access to internal representations or external knowledge bases. BEACON extracts a 31-dimensional feature vector from structured multi-pass generation, integrating NLI-based semantic ent
The proliferation of LLMs across critical applications necessitates robust methods for detecting hallucinations, and advances in AI model analysis are enabling new black-box detection techniques.
Improved hallucination detection enhances the trustworthiness and reliability of AI systems, expanding their practical deployment and commercial viability across various sectors.
The ability to detect LLM hallucinations without internal model representations or external knowledge bases creates a more flexible and robust validation paradigm for AI outputs.
