SKYLENAGE Technical Report: Mathematical Reasoning and Contest-Innovation Benchmarks for Multi-Level Math Evaluation

Hu Wei, Ze Xu, Boyu Yang +15

Large language models (LLMs) now perform strongly on many public math suites, yet frontier separation within mathematics increasingly suffers from ceiling effects. We present two c…

Moral Reasoning Across Languages: The Critical Role of Low-Resource Languages in LLMs

Huichi Zhou, Zehao Xu, Munan Zhao +3

In this paper, we introduce the Multilingual Moral Reasoning Benchmark (MMRB) to evaluate the moral reasoning abilities of large language models (LLMs) across five typologically di…
