arXiv:2606.11105v1 Announce Type: new Abstract: Hallucinations, where language models (LMs) generate factually ungrounded responses, pose serious risks, as users tend to blindly rely on them. This is particularly concerning in high-stakes domains, where consequences of such model behavior can lead to significant harms. Despite notable progress in understanding hallucinations, it remains unclear how reliably these models can recognize the limits of their knowledge. We introduce PhantomBench, the first large-scale benchmark of its kind, comprising more than 60K non-existent terms and entities de
As AI models become more pervasive and integrated into high-stakes applications, the urgent need to address their limitations, particularly hallucinations, intensifies.
The reliable identification and mitigation of AI hallucinations are crucial for building trust, ensuring safety, and enabling wider adoption of language models in critical domains.
The introduction of PhantomBench provides a standardized, large-scale method to benchmark and improve language models' ability to recognize the boundaries of their knowledge, pushing toward more reliable AI systems.
