arXiv:2605.30018v1 Announce Type: cross Abstract: Large language models (LLMs) frequently achieve impressive scores on standardized benchmarks, yet accuracy alone offers a limited view of their capabilities. Evaluating open-source LLMs through leaderboards faces persistent issues like data contamination, narrow task scope, and weak alignment with real-world reliability. Benchmark-based evaluations such as MMLU PRO, BBH, or IFEval primarily capture \textit{what} a model outputs on fixed test sets, not \textit{how} it processes information, calibrates uncertainty, or structures internal knowledg
The proliferation of LLMs and their increasing deployment in critical applications necessitates more robust and transparent evaluation methodologies beyond simple accuracy scores, which current benchmarks fail to provide.
A strategic reader should care because understanding LLM performance 'how' not just 'what' directly impacts their deployability, trustworthiness, and the strategic advantage derived from their use, affecting innovation and competitive landscapes.
The focus of LLM evaluation is shifting from output accuracy on fixed benchmarks to a more comprehensive understanding of internal processing, uncertainty calibration, and real-world reliability, impacting model development and adoption strategies.
