BLUEX v2: Benchmarking LLMs on Open-Ended Questions from Brazilian University Entrance Exams
arXiv:2606.22723v2 Announce Type: replace Abstract: Although Large Language Models (LLMs) excel in many tasks, their assessment in Portuguese has received less attention, particularly for open-ended, discursive tasks that demand deeper reasoning and generation capabilities. While the original BLUEX benchmark addressed the scarcity of Portuguese evaluation datasets through multiple-choice questions from Brazilian university entrance exams, it did not cover the more challenging second-phase examinations, which require free-form written responses. In this work, we introduce BLUEX v2, a benchmark
The rapid advancement of LLMs necessitates more sophisticated and diverse benchmarks, especially as their global deployment highlights language-specific performance gaps.
Sophisticated readers should care about the enhanced evaluation of LLMs in non-English languages, as it directly impacts their effective deployment and capability assessment in new markets and cultural contexts.
The introduction of BLUEX v2 provides a new, more challenging benchmark for assessing LLMs' reasoning and generation capabilities in Portuguese, moving beyond multiple-choice formats.
