arXiv:2605.26937v1 Announce Type: new Abstract: Parametric knowledge in large language models (LLMs) is a cornerstone of their success, yet remains poorly understood. Existing knowledge benchmarks typically rely on predefined questions (e.g., "What is the birth date of M.L. King?"), evaluating only knowledge that benchmark designers explicitly choose to query, a problematic availability bias. In this paper, we introduce open knowledge evaluation, a new paradigm for LLM knowledge benchmarking. Instead of asking narrow questions, it evaluates models on the knowledge they choose to surface in res
The rapid advancement and widespread deployment of large language models necessitates more robust and unbiased evaluation methods to understand their true capabilities and limitations beyond current question-answering benchmarks.
A nuanced understanding of LLM knowledge is critical for safely and effectively integrating these models into complex systems and for guiding future research toward more reliable AI systems.
The proposed 'open knowledge evaluation' paradigm shifts how LLM knowledge is assessed, moving away from pre-defined questions to evaluating knowledge models 'choose to surface,' potentially revealing deeper and broader understanding.

Improved methods for evaluating AI models will lead to a more accurate understanding of their capabilities and limitations.
This enhanced understanding will guide the development of more robust, transparent, and trustworthy large language models.
More reliable LLMs will accelerate their integration into sensitive applications, enabling new forms of automation and decision support.
