Hallucination Detection via Activations of Open-Weight Proxy Analyzers
Researchers introduce a proxy-analyzer framework that detects hallucinations in large language models by analyzing internal activations of a small open-weight reader model rather than the generator itself. The system achieves competitive or superior performance compared to existing methods across multiple model architectures, with notably consistent results showing that model size has minimal impact on detection accuracy.
